AB  - A specific feature of dyslipidemia in pregnancy is increased high-density lipoprotein (HDL) cholesterol concentration, which is probably associated with maternal endothelium protection. However, preeclampsia is most often associated with low HDL cholesterol, and the mechanisms behind this change are scarcely explored. We aimed to investigate changes in HDL metabolism in risky pregnancies and those complicated by late-onset preeclampsia. We analyze cholesterol synthesis (cholesterol precursors: desmosterol, 7-dehydrocholesterol, and lathosterol) and absorption markers (phytosterols: campesterol and β-sitosterol) within HDL particles (NCSHDL), the activities of principal modulators of HDL cholesterol’s content, and major HDL functional proteins levels in mid and late pregnancy. On the basis of the pregnancy outcome, participants were classified into the risk group (RG) (70 women) and the preeclampsia group (PG) (20 women). HDL cholesterol was lower in PG in the second trimester compared to RG (p < 0.05) and followed by lower levels of cholesterol absorption markers (p < 0.001 for campesterolHDL and p < 0.05 for β-sitosterolHDL). Lowering of HDL cholesterol between trimesters in RG (p < 0.05) was accompanied by a decrease in HDL phytosterol content (p < 0.001), apolipoprotein A-I (apoA-I) concentration (p < 0.05), and paraoxonase 1 (PON1) (p < 0.001), lecithin–cholesterol acyltransferase (LCAT) (p < 0.05), and cholesterol ester transfer protein (CETP) activities (p < 0.05). These longitudinal changes were absent in PG. Development of late-onset preeclampsia is preceded by the appearance of lower HDL cholesterol and NCSHDL in the second trimester. We propose that reduced capacity for intestinal HDL synthesis, decreased LCAT activity, and impaired capacity for HDL-mediated cholesterol efflux could be the contributing mechanisms resulting in lower HDL cholesterol.

AB  - Background/Aim. One of the complications that can oc-
cur during pregnancy is the development of preeclampsia
(PE). The main characteristics of this condition are high
blood pressure and very often signs of kidney damage or
other organ damage. The condition affects 5–7% of all
pregnant women and is one of the main factors of maternal
and perinatal morbidity and mortality worldwide. The aim
of this study was to investigate the structural and functional
modifications of high-density lipoprotein (HDL) particles
during high-risk pregnancies (HRP) for PE development.
Methods. The longitudinal prospective study included a to-
tal of 91 pregnant women with a HRP for developing PE.
Out of this total number, 71 women did not develop PE
until delivery, and this group was designated as the group
without PE (WPE). The rest of the 20 HRP women devel-
oped PE before delivery and were designated as the PE
group. The blood was sampled toward the end of each tri-
mester and before the delivery. The distribution of HDL
particles was determined by the vertical 3–31% polyacryla-
mide gradient gel electrophoresis method. The antioxidative capacity of HDL particles was measured by the activity of
the HDL-associated enzyme – paraoxonase 1 (PON1).
PON1 activity was determined by the method of kinetic
spectrophotometry from serum samples. Results. The re-
sults have shown that the proportions of HDL 2b particles
significantly increased in the 2nd trimester (p ˂ 0.05) and
remained increased until the end of pregnancy in the WPE
group. PON1 activity was significantly higher in the 3 rd tri-
mester (p < 0.05) of the WPE group. In the PE group, we
found that the proportions of HDL 3a particles significantly
decreased in the 2 nd trimester (p < 0.05) and remained de-
creased until the end of pregnancy. PON1 activity has not
changed in the PE group during pregnancy. Conclusion.
Dyslipidemia in pregnancy could be associated with differ-
ent modifications of HDL particles. The adaptive pregnancy
mechanisms expressed as a functional modification of HDL
particles in pregnant women who develop PE seem inade-
quate and, therefore, lose their atheroprotective role.

AB  - In order to understand the metabolic and immune potential of adiponectin in
colorectal cancer (CRC), attention is drawn to its receptors: adiponectin receptor 1
(ADIPOR1) and adiponectin receptor 2 (ADIPOR2). Gene set enrichment analysis (GSEA) of
datasets based on malignant tissue samples and peripheral blood monocytes (PBMs) was
used to explore mRNA fingerprints of different signaling pathways best associated with
ADIPOR1/ADIPOR2 gene expression levels. Transcriptomic datasets GSE44076 (1) and
GSE47756 (2) were downloaded from the NCBI Gene Expression Omnibus database. In the
GSE44076 dataset, three groups were formed: 98 colon tumor tissue and matched tumor-
adjacent mucosa samples and tissue samples from 50 healthy volunteers. The other set
(GSE47756) contained information on PBMs' gene signature in CRC, by forming two groups:
38 samples from healthy subjects and 55 CRC patients. GSEA analysis of the GSE44076
dataset implied that ADIPOR1 mRNA levels were in negative association with MTORC1 and
TNF-α NF-κB signaling pathways in tumor tissue. At the same time, ADIPOR2 was positively
associated with metabolic gene sets such as cholesterol homeostasis, glycolysis and PPAR
signaling. Quite opposite to the GSE44076 dataset, GSEA analysisis of GSE47756 revealed
that ADIPOR1 was a metabolically active receptor in PBMs of CRC patients. Surprisingly, the
TNF-α NF-κB signaling pathway gene sets were positively associated with ADIPOR1 mRNA
levels in monocytes of the cancer group. Different types of metabolic and immune regulation
achieved through ADIPOR1/ADIPOR2 in tumor and PBMs suggest possible novel therapeutic
targets in CRC.
AB  - Da bi se razumeo metabolički i imuni potencijal adiponektina u kolorektalnom
karcinomu (CRC), pažnja se mora obratiti i na njegove receptore: adiponektinski receptor 1
(ADIPOR1) i adiponektinski receptor 2 (ADIPOR2). Gene set enrichment analiza (GSEA) dva
skupa podataka, zasnovanih na uzorcima malignog tkiva i na monocitima periferne krvi
(PBM) je korišćena da bi se obezbedili genetski otisci različitih signalnih puteva koji su bili
najbolje povezani sa ekspresijom gena ADIPOR1/ADIPOR2. Skupovi transkriptomskih
podataka GSE44076 (1) i GSE47756 (2) su preuzeti iz NCBI Gene Expression Omnibus baze
podataka. U skupu podataka GSE44076 formirane su tri grupe: 98 uparenih uzoraka
tumorskog tkiva debelog creva i susedne mukoze i uzorci tkiva 50 zdravih dobrovoljaca.
Drugi set (GSE47756) je sadržao informacije o otisku gena PBM u CRC sa formiranim dvema
grupama: 38 uzoraka zdravih subjekata i 55 pacijenata sa CRC. GSEA analiza skupa podataka
GSE44076 je implicira da su nivoi iRNK ADIPOR1 negativno korelirali sa MTORC1 i TNF-α
NF-κB signalnim putevima u tumorskom tkivu. Istovremeno, ADIPOR2 je bio pozitivno
povezan sa skupovima gena metaboličkih puteva kao što su homeostaza holesterola,
glikoliza i PPAR signalizacija. Nasuprot GSE44076 skupu podataka, GSEA analiza GSE47756
transkriptomskog seta je otkrila da je ADIPOR1 zapravo metabolički aktivan receptor u PBM
pacijenata sa CRC. Iznenađujuć e, setovi gena koji su se odnosili na signalni put TNF-α NF-κB
su bili pozitivno povezani sa nivoima iRNK ADIPOR1 u monocitima grupe sa karcinomom.
Različite vrste metaboličke i imune regulacije koje se postižu preko ADIPOR1/ADIPOR2 u
tumoru i PBM sugerišu moguć e nove terapeutske ciljeve u CRC.

colorectal cancer (CRC), attention is drawn to its receptors: adiponectin receptor 1
(ADIPOR1) and adiponectin receptor 2 (ADIPOR2). Gene set enrichment analysis (GSEA) of
datasets based on malignant tissue samples and peripheral blood monocytes (PBMs) was
used to explore mRNA fingerprints of different signaling pathways best associated with
ADIPOR1/ADIPOR2 gene expression levels. Transcriptomic datasets GSE44076 (1) and
GSE47756 (2) were downloaded from the NCBI Gene Expression Omnibus database. In the
GSE44076 dataset, three groups were formed: 98 colon tumor tissue and matched tumor-
adjacent mucosa samples and tissue samples from 50 healthy volunteers. The other set
(GSE47756) contained information on PBMs' gene signature in CRC, by forming two groups:
38 samples from healthy subjects and 55 CRC patients. GSEA analysis of the GSE44076
dataset implied that ADIPOR1 mRNA levels were in negative association with MTORC1 and
TNF-α NF-κB signaling pathways in tumor tissue. At the same time, ADIPOR2 was positively
associated with metabolic gene sets such as cholesterol homeostasis, glycolysis and PPAR
signaling. Quite opposite to the GSE44076 dataset, GSEA analysisis of GSE47756 revealed
that ADIPOR1 was a metabolically active receptor in PBMs of CRC patients. Surprisingly, the
TNF-α NF-κB signaling pathway gene sets were positively associated with ADIPOR1 mRNA
levels in monocytes of the cancer group. Different types of metabolic and immune regulation
achieved through ADIPOR1/ADIPOR2 in tumor and PBMs suggest possible novel therapeutic
targets in CRC., Da bi se razumeo metabolički i imuni potencijal adiponektina u kolorektalnom
karcinomu (CRC), pažnja se mora obratiti i na njegove receptore: adiponektinski receptor 1
(ADIPOR1) i adiponektinski receptor 2 (ADIPOR2). Gene set enrichment analiza (GSEA) dva
skupa podataka, zasnovanih na uzorcima malignog tkiva i na monocitima periferne krvi
(PBM) je korišćena da bi se obezbedili genetski otisci različitih signalnih puteva koji su bili
najbolje povezani sa ekspresijom gena ADIPOR1/ADIPOR2. Skupovi transkriptomskih
podataka GSE44076 (1) i GSE47756 (2) su preuzeti iz NCBI Gene Expression Omnibus baze
podataka. U skupu podataka GSE44076 formirane su tri grupe: 98 uparenih uzoraka
tumorskog tkiva debelog creva i susedne mukoze i uzorci tkiva 50 zdravih dobrovoljaca.
Drugi set (GSE47756) je sadržao informacije o otisku gena PBM u CRC sa formiranim dvema
grupama: 38 uzoraka zdravih subjekata i 55 pacijenata sa CRC. GSEA analiza skupa podataka
GSE44076 je implicira da su nivoi iRNK ADIPOR1 negativno korelirali sa MTORC1 i TNF-α
NF-κB signalnim putevima u tumorskom tkivu. Istovremeno, ADIPOR2 je bio pozitivno
povezan sa skupovima gena metaboličkih puteva kao što su homeostaza holesterola,
glikoliza i PPAR signalizacija. Nasuprot GSE44076 skupu podataka, GSEA analiza GSE47756
transkriptomskog seta je otkrila da je ADIPOR1 zapravo metabolički aktivan receptor u PBM
pacijenata sa CRC. Iznenađujuć e, setovi gena koji su se odnosili na signalni put TNF-α NF-κB
su bili pozitivno povezani sa nivoima iRNK ADIPOR1 u monocitima grupe sa karcinomom.
Različite vrste metaboličke i imune regulacije koje se postižu preko ADIPOR1/ADIPOR2 u
tumoru i PBM sugerišu moguć e nove terapeutske ciljeve u CRC.",

AB  - Adiponectin (ADIPOQ) as both a regulator of metabolic homeostasis and a protein involved in immune response might be of particular interest to contemporary laboratory medicine, especially in terms of minimally invasive diagnostics. The diverse roles of ADIPOQ with regard to the immune and metabolic aspects of colorectal carcinogenesis have been proposed. However, the expression of its receptors ADIPOR1 and ADIPOR2 is scarcely explored in peripheral blood mononuclear cells (PBMCs). Moreover, ADIPORs’ relationships with the immune response mediator TNF-α have not been previously investigated in the PBMCs of CRC patients. This study used both in silico and observational case–control analyses with the aim of exploring the association of ADIPOR gene expression and ADIPOQ single nucleotide polymorphisms (SNPs) with the inflammatory marker TNF-α and lipid status parameters in patients with CRC. Publicly available transcriptomic datasets (GSE47756, GSE44076) obtained from analyses of monocytes and CRC tissue samples were employed for the in silico evaluation of ADIPORs’ specific genetic traits. GSE47756 and GSE44076 datasets were processed with GSEA software to provide a genetic fingertip of different signaling pathways associated with ADIPORs’ mRNA levels. The case–control aspect of the study included the PBMC samples of 73 patients diagnosed with CRC and 80 healthy volunteers. The PCR method was carried out for the PBMC gene expression analysis (ADIPOR1, ADIPOR2, TNF-α mRNA levels) and for the subjects’ genotyping (ADIPOQ rs266729, ADIPOR1 rs7539542). GSEA showed significant associations of ADIPOR mRNA expression with gene sets related to metabolic and immune homeostasis in both datasets. The case–control study revealed the association of ADIPOR1 rs7539542 with reduced lipid status parameters in CRC. In addition, PBMC ADIPOR1 mRNA levels decreased in CRC (p < 0.001), whereas ADIPOR2 mRNA did not differ between the groups (p = 0.442). A reduction in PBMC TNF-α mRNA levels was noted in CRC (p < 0.05). Our results indicate that ADIPOR1 and ADIPOR2 play a significant role in the alteration of both metabolic and immune homeostasis during the progression of CRC. For the first time, ADIPOR1 is shown to be a specific receptor for mediating ADIPOQ’s effects in the PBMCs of CRC patients.

AB  - Objectives: Obstructive sleep apnea (OSA) is a common condition closely related to obesity, insulin resistance, dyslipidemia, and cardiovascular disease. The aim of this study was to explore the possible relationship between OSA and proprotein convertase subtilisin/kexin type 9 (PCSK9). Methods: Full-night polysomnography was performed on 150 participants who were divided into three groups: controls, OSA patients on statin therapy, and OSA patients not on statin therapy. Biochemical markers, plasma low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subclasses, and PCSK9 were determined. Results: PCSK9 was highest in OSA patients on statins compared to the control group and to OSA patients not on statins (p = 0.036 and p = 0.039, respectively), after adjustment for body mass index (BMI). LDL diameter was greater in OSA patients not on statins compared to OSA patients on statins (p = 0.032). PCSK9 was highest in the group of patients with all three risk factors (diagnosed OSA, statins, BMI ≥25 kg/m2) compared to groups with no, one, and two risk factors (p = 0.031, p = 0.001, and p = 0.029, respectively). Presence of OSA, statin therapy, and BMI ≥25 kg/m2 when combined were independently associated with higher levels of PCSK9 when adjusted for antihypertensive therapy, small dense LDL, and HDL 3c subclass (odds ratio = 2.849; interquartile range [1.026–7.912], p = 0.044). Conclusion: Statin therapy was closely related to PCSK9. OSA along with obesity and statin use induces elevation of PCSK9.

AB  - Background and aims: Obstructive sleep apnea (OSA) is closely linked to obesity and related adverse metabolic changes, including dyslipidemia. However, it is not clear whether OSA is an independent contributing factor to dyslipidemia, or the observed association is a reflection of a concomitant presence of obesity. Additionally, dyslipidemia is usually evaluated through measurement of parameters of routine lipid status, while more precise evaluation of lipid homeostasis is rarely performed in OSA. In this study, we analyzed markers of cholesterol synthesis and absorption in patients with OSA with respect to the presence of obesity and the disease severity. Methods and results: This study enrolled 116 OSA patients. Concentrations of non-cholesterol sterols (NCS), measured by LC-MS/MS, were used as markers of cholesterol synthesis and absorption. Apnea-hypopnea index (AHI) and oxygen saturation (SaO2) were utilized as markers of OSA severity. Serum lipid status parameters were determined by routine enzymatic methods. Markers of cholesterol synthesis were increased (P = 0.005), whilst markers of cholesterol absorption decreased (P = 0.001) in obese OSA patients. Cholesterol synthesis/absorption ratio was elevated in obese subjects (P < 0.001). Concentration of cholesterol synthesis marker lathosterol was significantly higher in subjects with severe OSA (P = 0.014) and we observed a trend of decreased cholesterol absorption in these patients. AHI was revealed as an independent determinant of lathosterol concentration (P = 0.022). Conclusions: Our results suggest that the presence of obesity and severe forms of OSA is characterized by elevated endogenous cholesterol synthesis. AHI was singled out as an independent determinant of the serum level of cholesterol synthesis marker lathosterol.

AB  - Metabolic disorders in pregnancy, particularly gestational diabetes mellitus (GDM), are associated with an increased risk for adverse pregnancy outcome and long-term cardiometabolic health of mother and child. This study analyzed changes of serum cholesterol synthesis and absorption markers during the course of high-risk pregnancies, with respect to the development of GDM. Possible associations of maternal lipid biomarkers with neonatal characteristics were also investigated. The study included 63 women with high risk for development of pregnancy complications. Size and proportions of small low-density (LDL) and high-density lipoprotein (HDL) particles were assessed across trimesters (T1–T3), as well as concentrations of cholesterol synthesis (lathosterol, desmosterol) and absorption markers (campesterol, β-sitosterol). During the study, 15 women developed GDM, while 48 had no complications (non-GDM). As compared to the non-GDM group, women with GDM had significantly higher triglycerides in each trimester, while having a lower HDL-C level in T3. In addition, they had significantly lower levels of β-sitosterol in T3 (p < 0.05). Cholesterol synthesis markers increased across trimesters in both groups. A decrease in serum β-sitosterol levels during the course of pregnancies affected by GDM was observed. The prevalence of small-sized HDL decreased in non-GDM, while in the GDM group remained unchanged across trimesters. Newborn’s size in the non-GDM group was significantly higher (p < 0.01) and inversely associated with proportions of both small, dense LDL and HDL particles (p < 0.05) in maternal plasma in T1. In conclusion, high-risk pregnancies affected by GDM are characterized by altered cholesterol absorption and HDL maturation. Advanced lipid testing may indicate disturbed lipid homeostasis in GDM.

This study analyzed changes of serum cholesterol synthesis and absorption markers during the course of high-risk pregnancies, with respect to the development of GDM. Possible associations of maternal lipid biomarkers with neonatal characteristics were also investigated. The study included 63 women with high risk for development of pregnancy complications. Size and proportions of small low-density (LDL) and high-density lipoprotein (HDL) particles were assessed across trimesters (T1–T3), as well as concentrations of cholesterol synthesis (lathosterol, desmosterol) and absorption markers (campesterol, β-sitosterol). During the study, 15 women developed GDM, while 48 had no complications (non-GDM). As compared to the non-GDM group, women with GDM had significantly higher triglycerides in each trimester, while having a lower HDL-C level in T3. In addition, they had significantly lower levels of β-sitosterol in T3 (p < 0.05). Cholesterol synthesis markers increased across trimesters in both groups. A decrease in serum β-sitosterol levels during the course of pregnancies affected by GDM was observed.

AB  - Introduction  The aim of this study was to investigate lipoprotein particle distributions and the likelihood of achieving cholesterol homeostasis in the remission phase of nephrotic syndrome (NS) in paediatric patients. We hypothesized that lipoprotein particle distributions moved toward less atherogenic profile and that cholesterol homeostasis was achieved. Materials and methods  Thirty-three children, 2 to 9 years old with NS were recruited. Blood sampling took place both in the acute phase and during remission. Serum low-density lipoprotein particles (LDL) and high-density lipoprotein particles (HDL) were separated using non-denaturing polyacrylamide gradient gel (3-31%) electrophoresis. Serum non-cholesterols sterols (NCSs), desmosterol, lathosterol, 7-dehydrocholesterol (7-DHC), campesterol and β-sitosterol were measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Results  All patients had desirable serum HDL cholesterol concentrations during remission. The dominant lipoprotein diameters and LDL subclass distribution did not change significantly during follow-up. In contrast, HDL lipoprotein particle distribution shifted towards larger particles. The absolute concentration of desmosterol was significantly lower during remission (P = 0.023). β-sitosterol concentration markedly increased during remission (P = 0.005). Desmosterol/β-sitosterol (P < 0.001) and 7-DHC/β-sitosterol (P = 0.005) ratios significantly declined during disease remission. Conclusions  Favourable changes in the serum lipid profiles, HDL particle subclass distribution and cholesterol metabolism in paediatric patients with NS during remission took place. For the first time, we found that cholesterol homeostasis changed in favour of increased cholesterol absorption during disease remission. Nevertheless, complete cholesterol homeostasis was not achieved during disease remission.

AB  - Compelling evidence supports the causative link between increased levels of low-density lipoprotein cholesterol (LDL-C) and atherosclerotic cardiovascular disease (CVD) development. For that reason, the principal aim of primary and secondary cardiovascular prevention is to reach and sustain recommended LDL-C goals. Although there is a considerable body of evidence that shows that lowering LDL-C levels is directly associated with CVD risk reduction, recent data shows that the majority of patients across Europe cannot achieve their LDL-C targets. In attempting to address this matter, a new overarching concept of a lipid-lowering approach, comprising of even more intensive, much earlier and longer intervention to reduce LDL-C level, was recently proposed for high-risk patients. Another important concern is the residual risk for recurrent cardiovascular events despite optimal LDL-C reduction, suggesting that novel lipid biomarkers should also be considered as potential therapeutic targets. Among them, small dense LDL particles (sdLDL) seem to have the most significant potential for therapeutic modulation. This paper discusses the potential of traditional and emerging lipid-lowering approaches for cardiovascular prevention by targeting sdLDL particles.

AB  - Despite significant progress in improving pregnancy outcomes in recent decades,
predicting the risk and treatment of preeclampsia are still major challenges in clinical
practice (1). The aim of this study was to examine non-routine biomarkers in preeclampsia
risk assessment. The study involved 90 women with high-risk pregnancies, 20 of whom
developed preeclampsia by the end of pregnancy. Biochemical parameters were determined
between the 12th and 13 th weeks of gestation. The results of the study showed that women
who later developed preeclampsia had higher concentrations of lathosterol, cholesterol
synthesis marker (p <0.05), inflammatory proteins - monocyte chemoattractant protein-1
(MCP-1), and resistin (p <0.01, both), as well as paraoxonase-1 (PON1) activity (p <0.05).
Binary logistic regression analysis showed that higher concentrations of lathosterol, MCP-1,
resistin, and PON-1 were associated with preeclampsia development. To determine whether
the parameters significant in univariate analysis, are independent predictors of
preeclampsia, we applied multivariate regression analysis. Clinical markers commonly used
in risk assessment (maternal age and body mass index, mean arterial pressure, and uterine
blood flow), lathosterol, MCP-1, resistin, and PON-1 were included in the model. MCP-1 and
resistin stood out as significant independent predictors of preeclampsia. The diagnostic
accuracy of the investigated model was excellent (AUC=0.859). The study results indicated
the importance of a multi-marker approach in risk assessment for preeclampsia
development.

Cilj ove studije je bio ispitivanje biomarkera koji se ne koriste u rutinskoj praksi u proceni

su određivani između 12. i 13. nedelje gestacije. Rezultati studije su pokazali da su žene koje
su razvile preeklampsiju imale više koncentracije latosterola, markera sinteze holesterola (p
<0,05), inflamatornih proteina - monocitnog hemoatraktantnog proteina-1 (MCP-1) i
rezistina (p < 0,01, oba), kao i aktivnost enzima paraoksonaze-1 (PON1) (p <0,05). Binarna
logistička regresiona analiza je pokazala da su više koncentracije latosterola, MCP-1,
rezistina i PON-1 povezane sa razvojem preeklampsije. Da bi se utvrdilo da su parametri koji
su se u univarijantnoj analizi pokazali značajnim, nezavisni prediktori preeklampsije,

AB  - Insulin resistance, hyperlipidemia, oxidative stress and low-grade inflammation are
mechanisms underlying endothelial dysfunction and atherosclerosis development in non-
pregnant state, but in pregnancy they are adaptive mechanisms responsible for fetal
development without health risks for mothers. A special feature of lipids profile in pregnancy
is increase in high density lipoprotein (HDL) cholesterol concentration. Protective role of
HDL particles resides on its complex composition that goes beyond its cholesterol
concentration and exhibits vasodilatory, antioxidant, anti-inflammatory and
antithrombogenic effects. Even the importance of HDL functionality in pathogenesis of
cardiovascular disease has been investigated and confirmed its role in persevering metabolic
health in pregnancy are almost unexplored. Project "HDL research to improve pregnancy
outcome" investigate the pattern of HDL particle distribution and functionality (HDL-ome)
with different pregnancy outcomes. With the sophisticated analytical methods we determine
HDL-ome in uncomplicated and high-risk pregnancies. We mark the HDL-ome component
with a different pattern of change during high-risk pregnancies and test their potential for
pregnancy complications risk assessment. In this this research we investigate molecular
mechanisms crucial for HDL remodelling during pregnancy and possible associations
between maternal metabolic health during pregnancy and maternal and child health in the
future. Such comprehensive approach will provide a better insight into HDL role in maternal
metabolic health during pregnancy and will open a door for further research in this area.
AB  - Insulinska rezistencija, hiperlipidemija, oksidativni stress i stanje inflamacije niskog
stepena, koji se u negravidnom stanju povezuju sa razvojem endotelne disfunkcije i
aterosklerozom, u trudnoći predstavljaju adaptivne mehanizme koji omogućavaju pravilan
rast i razvoj fetusa, a ne ugrožavaju zdravlje trudnice. Specifičnost dislipidemije koja se
razvija u trudnoći, a koja nije karakteristična za dislipidemiju u negravidnim stanjima, jeste
porast koncentracije holesterola u lipoproteinskim česticama visoke gustine (high density
lipoprotein, HDL). Međutim, HDL je mnogo više od sadržaja holesterola u njemu. Ovaj
lipoprotein ima izuzetno kompleksnu i heterogenu strukturu i ispoljava vazodilatatorne,
antioksidativne, antiinflamatorne i antitrombogene efekte. Iako je gubitak funkcionalnosti
ovog lipoproteina u patogenezi kardiovaskularnih bolesti detaljno ispitan i potvrđen,
njegova uloga u očuvanju metaboličkog zdravlja u trudnoći još uvek nije rasvetljena. Projekat
"Ispitivanje HDL-metaboloma u cilju unapređenja ishoda trudnoće" bavi se istraživanjem
povezanosti obrazaca promena strukture i funkcionalnosti HDL (HDL-om) sa različitim
ishodima trudnoće. Sofisticiranim analitičkim metodama, određuje se HDL-om u
visokorizičnim trudnoćama, kao i trudnoćama bez komplikacija. Izdvajaju se komponente

abstract = "Insulin resistance, hyperlipidemia, oxidative stress and low-grade inflammation are
mechanisms underlying endothelial dysfunction and atherosclerosis development in non-
pregnant state, but in pregnancy they are adaptive mechanisms responsible for fetal
development without health risks for mothers. A special feature of lipids profile in pregnancy
is increase in high density lipoprotein (HDL) cholesterol concentration. Protective role of
HDL particles resides on its complex composition that goes beyond its cholesterol
concentration and exhibits vasodilatory, antioxidant, anti-inflammatory and
antithrombogenic effects. Even the importance of HDL functionality in pathogenesis of
cardiovascular disease has been investigated and confirmed its role in persevering metabolic
health in pregnancy are almost unexplored. Project "HDL research to improve pregnancy
outcome" investigate the pattern of HDL particle distribution and functionality (HDL-ome)
with different pregnancy outcomes. With the sophisticated analytical methods we determine
HDL-ome in uncomplicated and high-risk pregnancies. We mark the HDL-ome component
with a different pattern of change during high-risk pregnancies and test their potential for
pregnancy complications risk assessment. In this this research we investigate molecular
mechanisms crucial for HDL remodelling during pregnancy and possible associations
between maternal metabolic health during pregnancy and maternal and child health in the
future. Such comprehensive approach will provide a better insight into HDL role in maternal
metabolic health during pregnancy and will open a door for further research in this area., Insulinska rezistencija, hiperlipidemija, oksidativni stress i stanje inflamacije niskog
stepena, koji se u negravidnom stanju povezuju sa razvojem endotelne disfunkcije i
aterosklerozom, u trudnoći predstavljaju adaptivne mehanizme koji omogućavaju pravilan
rast i razvoj fetusa, a ne ugrožavaju zdravlje trudnice. Specifičnost dislipidemije koja se
razvija u trudnoći, a koja nije karakteristična za dislipidemiju u negravidnim stanjima, jeste
porast koncentracije holesterola u lipoproteinskim česticama visoke gustine (high density
lipoprotein, HDL). Međutim, HDL je mnogo više od sadržaja holesterola u njemu. Ovaj
lipoprotein ima izuzetno kompleksnu i heterogenu strukturu i ispoljava vazodilatatorne,
antioksidativne, antiinflamatorne i antitrombogene efekte. Iako je gubitak funkcionalnosti
ovog lipoproteina u patogenezi kardiovaskularnih bolesti detaljno ispitan i potvrđen,
njegova uloga u očuvanju metaboličkog zdravlja u trudnoći još uvek nije rasvetljena. Projekat
"Ispitivanje HDL-metaboloma u cilju unapređenja ishoda trudnoće" bavi se istraživanjem
povezanosti obrazaca promena strukture i funkcionalnosti HDL (HDL-om) sa različitim
ishodima trudnoće. Sofisticiranim analitičkim metodama, određuje se HDL-om u
visokorizičnim trudnoćama, kao i trudnoćama bez komplikacija. Izdvajaju se komponente
HDL-oma koje imaju drugačiji obrazac promene tokom visoko rizičnih trudnoća i ispituje se
njihov značaj u proceni rizika za razvoj komplikacija u trudnoći. Poseban aspekt ovog
istraživanja odnosi se na ispitivanje molekularnih mehanizama ključnih za remodelovanje
HDL tokom trudnoće, kao i potencijalne povezanosti metaboličkog statusa majke tokom

AB  - High-density lipoprotein (HDL) is the most complex lipoprotein particle, containing
lipids and dozens of various functional proteins. Such sophisticated composition enables
numerous activities of HDL; from the reverse cholesterol transport, to antioxidative, anti-
inflammatory, anti-aggregation, antiadhesive, and vasodilatory effects. Accordingly, the
significance of HDL goes far beyond its cardioprotective properties and novel research
points towards its role in etiopathogenesis of various other diseases. Antioxidative
properties of HDL are primarily attributed to the enzyme paraoxonase 1 (PON1), whose
principal role is to protect low-density lipoprotein (LDL) and cell membranes against
harmful effects of reactive oxygen species (1). PON1 is located on HDL particles and its
activity largely depends on HDL structure. Our investigations have shown that PON1 is not
equally distributed across the entire population of serum HDL subfractions. Namely, our
results suggest that the allocation of PON1 on specific HDL subclasses changes in
pathophysiological conditions, such as chronic kidney disease, polycystic ovary syndrome, or
hypertension in pregnancy. Similarly, a shift in HDL subclasses distribution toward smaller,
dysfunctional particles is reported in diabetes, metabolic syndrome, obstructive sleep apnea,
sarcoidosis, but also in malignant diseases, such as colorectal cancer. In parallel,
antioxidative defense mechanisms were diminished in all these categories of patients, which
was evident as decreased PON1 activity and rise of oxidative stress. Structural modifications
of HDL particles affect their functions, thus antioxidative capability of PON1 depends on
qualitative properties of its lipoprotein carrier. Such complex interaction is highly significant
for the initiation and progression of numerous diseases.

AB  - Introduction The link between preeclampsia and dyslipidemia has been established. Even though lipid profile parameters have been intensively investigated in the pathology of preeclampsia, their accurate molecular mechanisms of action have not been fully decoded. Objectives We aimed to identify the specifics of cholesterol metabolism in women affected by late‑onset preeclampsia and single out potential biomarkers associated with late‑onset syndrome. Patient s and methods A total of 90 pregnant women with a priori risk for preeclampsia were monitored at 4 time points during gestation and, based on the outcome of pregnancy, they were classified into the high‑risk group (70 women) and the preeclampsia group (20 women). Cholesterol metabolic profiling was done using liquid chromatography‑tandem mass spectrometry. Result s The only significant change in the preeclampsia group was an increase in the lathosterol level (P = 0.001). The first‑trimester lathosterol level was higher in the preeclampsia group compared with the high‑risk group (P = 0.02). Further, in the preeclampsia group, positive correlations were found between desmosterol and β‑sitosterol (ρ = 0.474; P = 0.03) in the third trimester, desmosterol and campesterol changes between the second and the first (ρ = 0.546; P = 0.02), and the third and first trimesters (ρ = 0.754; P <0.001), as well as between the desmosterol and β‑sitosterol differences between the third and first trimesters (ρ = 0.568; P = 0.01). No similar correlations were found in the high‑risk group. Conclusions Late‑onset preeclampsia could be associated with an altered lipid profile. By studying the quantitative metabolic signatures of cholesterol, we might assume that both cholesterol synthesis and absorption are increased, that is, there is an imbalance in the cholesterol homeostasis regulation in women affected by the disease.

abstract = "Introduction The link between preeclampsia and dyslipidemia has been established. Even though lipid profile parameters have been intensively investigated in the pathology of preeclampsia, their accurate molecular mechanisms of action have not been fully decoded. Objectives We aimed to identify the specifics of cholesterol metabolism in women affected by late‑onset preeclampsia and single out potential biomarkers associated with late‑onset syndrome. Patient s and methods A total of 90 pregnant women with a priori risk for preeclampsia were monitored at 4 time points during gestation and, based on the outcome of pregnancy, they were classified into the high‑risk group (70 women) and the preeclampsia group (20 women). Cholesterol metabolic profiling was done using liquid chromatography‑tandem mass spectrometry. Result s The only significant change in the preeclampsia group was an increase in the lathosterol level (P = 0.001). The first‑trimester lathosterol level was higher in the preeclampsia group compared with the high‑risk group (P = 0.02). Further, in the preeclampsia group, positive correlations were found between desmosterol and β‑sitosterol (ρ = 0.474; P = 0.03) in the third trimester, desmosterol and campesterol changes between the second and the first (ρ = 0.546; P = 0.02), and the third and first trimesters (ρ = 0.754; P <0.001), as well as between the desmosterol and β‑sitosterol differences between the third and first trimesters (ρ = 0.568; P = 0.01). No similar correlations were found in the high‑risk group. Conclusions Late‑onset preeclampsia could be associated with an altered lipid profile. By studying the quantitative metabolic signatures of cholesterol, we might assume that both cholesterol synthesis and absorption are increased, that is, there is an imbalance in the cholesterol homeostasis regulation in women affected by the disease.",

AB  - Preeclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality worldwide. Defects in trophoblast invasion, differentiation of extravillous trophoblasts and spiral artery remodeling are key factors in PE development. Currently there are no predictive biomarkers clinically available for PE. Recent technological advancements empowered transcriptome exploration and led to the discovery of numerous non-coding RNA species of which microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are the most investigated. They are implicated in the regulation of numerous cellular functions, and as such are being extensively explored as potential biomarkers for various diseases. Altered expression of numerous lncRNAs and miRNAs in placenta has been related to pathophysiological processes that occur in preeclampsia. In the following text we offer summary of the latest knowledge of the molecular mechanism by which lnRNAs and miRNAs (focusing on the chromosome 19 miRNA cluster (C19MC)) contribute to pathophysiology of PE development and their potential utility as biomarkers of PE, with special focus on sample selection and techniques for the quantification of lncRNAs and miRNAs in maternal circulation.

AB  - Epidemiological data have demonstrated a significant association between the presence of type 2 diabetes mellitus (T2DM) and the development of colorectal cancer (CRC). Chronic hyperglycemia, insulin resistance, oxidative stress, and inflammation, the processes inherent to T2DM, also play active roles in the onset and progression of CRC. Recently, small dense low-density lipoprotein (LDL) particles, a typical characteristic of diabetic dyslipidemia, emerged as another possible underlying link between T2DM and CRC. Growing evidence suggests that antidiabetic medications may have beneficial effects in CRC prevention. According to findings from a limited number of preclinical and clinical studies, glucagon-like peptide-1 receptor agonists (GLP-1RAs) could be a promising strategy in reducing the incidence of CRC in patients with diabetes. However, available findings are inconclusive, and further studies are required. In this review, novel evidence on molecular mechanisms linking T2DM with CRC development, progression, and survival will be discussed. In addition, the potential role of GLP-1RAs therapies in CRC prevention will also be evaluated.

AB  - Objective: Type 1 diabetes (T1D) mellitus is one of the most frequent autoimmune diseases in childhood. Chronic complications are the main causes of cardiovascular morbidity and mortality in T1D. Although interactions between advanced glycation end products (AGE) and their receptors (RAGE) and transforming growth factor-β1 (TGF-β1) are implicated in development and progression of diabetic micro-and macro-vascular complications, they also have important roles in immune system regulation. Methods: Blood samples were obtained from 156 adolescents with T1D and 80 apparently healthy controls. T1D patients diagnosed with any other autoimmune disease and receiving any kind of drugs except insulin therapy were excluded from this study. Exclusion criteria for controls were positive family history of T1D and drugs/supplements application. TGF-β1 and transmembrane full-length RAGE (flRAGE) messenger ribonucleic acid (mRNA) levels in peripheral blood mononuclear cells (PBMC) were obtained by quantitative polymerase chain reaction (qPCR) method. Circulating levels of biochemical markers, TGF-β1 and soluble RAGE (sRAGE) levels were also determined. Results: TGF-β1 and flRAGE mRNA levels were significantly higher in controls compared to patients (p<0.001, for both). However, TGF-β1 and sRAGE levels were higher in patients than controls (p<0.001, for both). There were significant independent associations of all mRNA and protein levels with T1D. TGF-β1 mRNA was the only marker independently negatively associated with urinary albumin excretion rate in T1D adolescents (p=0.005). Conclusion: Our results indicated gene expression downregulation of TGF-β1 and flRAGE in PBMC of T1D adolescents. TGF-β1 mRNA downregulation may be useful for predicting early elevation of urinary albumin excretion rate.

AB  - Objectives: The goal of this study was to investigate metabolic changes in lipids and oxidative stress parameters in the first trimester of pregnancy with the more specific aim of estimating the significance and strength of researched parameters in the prediction of preeclampsia. Design and Methods. The study included 87 high-risk pregnant (HRG) female subjects, 14 with developed preeclampsia (PEC) and 43 healthy pregnant female subjects matched for gestational age (CG). Thiobarbituric acid-reactive substances (TBARS) concentration, lipid hydroperoxides (LOOH), pro-oxidant antioxidant balance (PAB) and total oxidative status (TOS) were measured as oxidative stress markers, while total antioxidant capacity (TAC) was measured as an antioxidative defense parameter. The Atherogenic Index of Plasma (AIP) was calculated as the base 10 logarithm of the ratio of the plasma concentration of triglycerides (TG) to the plasma concentration of highdensity lipoprotein cholesterol (HDL-C), with each concentration expressed in mmol/L. Results: The results have shown that lipid indices, especially AIP, were significantly higher in the first trimester of HRG (p < 0.001) and PEC (p < 0.001). Oxidative stress parameters were significantlly higher, while TAC was significantly lower in HRG vs. CG [0.7 ± 0.15 vs 1.1 ± 0.16; (p < 0.001)] and in PEC [0.6 ± 0.12 vs 1.1 ± 0.16; (p < 0.001)] vs. CG. Also, in the HRG, results have shown an independent association of AIP with the preeclampsia development (p < 0.05), while placental growth factor did not show the expected level of significance (p = 0.648). Analysis of the Receiver Operating Characteristics (ROC) curves indicated that certain parameters included in the research model have very good diagnostic accuracy for preeclampsia (AUC = 0.856). Conclusions: AIP is associated with high-risk pregnancies. Furthermore, our results firmly underscored AIP as a potential marker for preeclampsia prediction.

AB  - Background: We evaluated the qualitative characteristics of high-density lipoprotein (HDL) particles in metabolically healthy and unhealthy overweight and obese subjects. Methods: The study involved 115 subject individuals classified as metabolically healthy and unhealthy, as in overweight and obese groups. Commercial enzyme-linked immunosorbent assay (ELISA) kits were used to measure oxidized HDL (OxHDL) and serum amyloid A (SAA) concentrations. Lipoprotein subfractions were separated using nondenaturing gradient gel electrophoresis. Results: An independent association was shown between increased OxHDL/HDL-cholesterol ratio and the occurrence of metabolically unhealthy phenotype in the overweight and obese groups. The OxHDL/HDL-cholesterol ratio showed excellent and acceptable diagnostic accuracy in determination of metabolic health phenotypes (overweight group, AUC = 0.881; obese group, AUC = 0.765). Accumulation of smaller HDL particles in metabolically unhealthy subjects was verified by lipoprotein subfraction analysis. SAA concentrations did not differ significantly between phenotypes. Conclusions: Increased OxHDL/HDL-cholesterol ratio may be a potential indicator of disturbed metabolic health in overweight and obese individuals.

AB  - Aim: Despite many efforts, reliable biomarkers for the prediction and diagnosis of colorectal cancer (CRC) are still missing. Insulin-like growth factor 1 (IGF-1) and E-cadherin are recognized as potential biomarkers, but their diagnostic capacity is largely unexplored in CRC. The aim of this work is to investigate IGF-1 and E-cadherin levels with respect to various characteristics of CRC and to estimate their diagnostic potential. Method: Seventy CRC patients and 75 healthy individuals were enrolled. IGF-1 and E-cadherin were determined using enzyme-linked immunosorbent assay. The predictive and diagnostic capacities of IGF-1 and E-cadherin were estimated by logistic regression analysis and by determination of the area under the receiver operating characteristic (ROC) curve (AUC). Results: Concentrations of IGF-1 were lower (P = 0.019) while levels of E-cadherin were higher (P < 0.001) in CRC patients than in controls. IGF-1 concentration decreased in parallel with age and progression of CRC (P = 0.023). Also, IGF-1 was higher in men with CRC than in women (P = 0.003). E-cadherin levels were unaffected by variations in either anthropometric characteristics of CRC patients, or localization, grade and stage of the tumour. Both IGF-1 and E-cadherin were independently associated with CRC (P = 0.040; P < 0.001, respectively). The diagnostic accuracy of IGF-1 was estimated as acceptable (AUC = 0.757; P < 0.001), while the diagnostic accuracy of E-cadherin was outstanding (AUC = 0.954; P < 0.001). Conclusions: Decreased IGF-1 and increased E-cadherin levels were found in CRC patients. IGF-1, but not E-cadherin, concentrations differed according to age, gender and stage of CRC. Both markers were independently associated with the presence of the disease, while E-cadherin demonstrated high diagnostic accuracy.

AB  - A direct and an indirect relationship between paraoxonase 1 (PON1) and atherosclerosis exists. Given PON1's physical location within high-density lipoprotein (HDL) particles and its recognized enzyme activity, it is certainly reasonable to suggest that PON1 facilitates the antiatherogenic nature of HDL particles. PON1 also plays a role in regulating reverse cholesterol transport, antioxidative, anti-inflammatory, antiapoptotic, vasodilative, and antithrombotic activities and several endothelial cell functions. HDL dysfunctionality is a more recent issue and seems to be centered on pathological conditions affecting HDL structure and size profiles. This review is focused on the role of PON1 status in different atherosclerosis-related diseases that we have studied over the last twenty years (coronary heart disease, acute ischemic stroke, diabetes mellitus type 2, end-stage renal disease, chronic obstructive pulmonary disease, and sarcoidosis) with the aim to determine the true value of PON1 as a biomarker. The role of PON1 in cancer is also covered, as risk factors and mechanisms underlying both atherosclerosis and cancer share common features. © 2019 International Union of Biochemistry and Molecular Biology

AB  - Background:Vitamin D deficiency is repeatedly reported in colorectal  cancer  (CRC).  Since  cholesterol  and  vitamin  D share common precursor 7-dehydrocholesterol (7-DHC), it would be important to explore the associations of key vitamin D metabolites and serum lipid parameters in patients with high and low grade CRC. The aim of this study was toanalyze    relationships    between    serum    25(OH)D3,24,25(OH)2D3  and  7-DHC  levels  and  serum  lipids  inpatients with CRC, and to evaluate their potential for prediction of risk for development of high grade CRC. Methods:We  recruited  82  patients  CRC  and  77  controls.7-DHC, 25(OH)D3 and 24,25(OH)2D3 were quantified by LC-MS/MS methods.Results:7-DHC, 25(OH)D3 and vitamin D metabolic ratio(VDMR)  were  significantly  lower  in  CRC  patients  than  in control   group   (P<0.001,   P<0.010,   P<0.050   and P<0.050,  respectively).  25(OH)D3  levels  were  higher  inpatients  with  grade  I  CRC  when  compared  to  grade  II(P<0.050). All vitamin D metabolites positively correlated with  total  cholesterol  (TC)  concentration  in  CRC  patients.25(OH)D3 was significant predictor of increased CRC risk(P<0.010).   After   adjustment   for   TC   concentration,25(OH)D3 lost its predictive abilities. However, 25(OH)D3 remained significant predictor of poorly differentiated type of cancer (P<0.050). Conclusions:We  found  significant  positive  association between  vitamin  D  status  and  serum  total  cholesterol.Although low 25(OH)D3 was found to be a significant risk factor for CRC development, the obtained results primarily suggest profound impact of cholesterol level on vitamin D status  in  CRC.  However,  our  results  suggest  that  low 25(OH)D3 might independently contribute to development of poorly differentiated tumor.

U ovom radu ispitivali smo odnos između serumskih koncentracija 25(OH)D3, 24,25(OH)2D3 and 7-DHC i serumskih lipida kod pacijenata sa CRC, kao i doprinos metabolita vitamina D u predikciji rizika za nastanak CRC visokog gradusa. Metode: U studiji su učestvovala 82 pacijenta sa CRC i 77 zdravih ispitanika. 7-DHC, 25(OH)D3 i 24,25(OH)2D3 su kvantifikovani pomoću metode LC-MS/MS. Rezultati: 7-DHC, 25(OH)D3 i odnos metabolita vitamina D (VDMR) su bili značajno niži kod pacijenata sa CRC u odnosu na kontrolnu grupu (P<0,001, P<0,010, P<0,050 i P<0,050, redom). Koncentracije 25(OH)D3 su bile više kod pacijenata sa gradusom I u odnosu na pacijente sa gradusom II (P<0,050). Svi metaboliti vitamina D su pozitivno korelirali sa ukupnim holesterolom kod pacijenata sa CRC. 25(OH)D3 je bio značajan prediktor povećanog rizika za nastanak CRC (P<0,010). Nakon korekcije za koncentraciju ukupnog holesterola, 25(OH)D3 je izgubio prediktivni značaj. Međutim, 25(OH)D3 je ostao značajan prediktor slabo diferenciranog karcinoma (P<0,050).
