Objectives: This study aims to elucidate the expression patterns of LGALS1 (galectin-1) and LGALS9 (galectin-9) genes in placental tissues of pregnancies affected by preterm prelabor rupture of membranes (PPROM). The overarching goal is to understand the potential roles of these galectins in the pathophysiology of PPROM, particularly in maternal-fetal immune tolerance and placental development.

Material And Methods: Conducted as a prospective, single-center study at the Gynecology and Obstetrics Clinical Hospital in Poznan, Poland, from June 2021 to May 2023, the research involved 25 participants, including 12 with PPROM and 13 healthy controls.

Genetic risk score for gestational weight gain.

Gestational weight gain (GWG) involves health consequences for both mother and offspring. Genetic factors seem to play a role in the GWG trait. For small effect sizes of a single genetic polymorphism (SNP), a genetic risk score (GRS) summarizing risk-associated variation from multiple SNPs can serve as an effective approach to genetic association analysis.

Comprehensive Analysis of the Role of Gene Variants in Matrix Metalloproteinases and Their Tissue Inhibitors in Retinopathy of Prematurity: A Study in the Polish Population.

This study was designed to investigate the relationship between variants of matrix metalloproteinases (-1 rs179975, -9 rs17576 and rs17577), their tissue inhibitors (-1 rs4898, -2 rs2277698 and rs55743137) and the development of retinopathy of prematurity (ROP) in infants from the Polish population. A cohort of 100 premature infants (47% female) was enrolled, including 50 ROP cases and 50 no-ROP controls. Patients with ROP were divided into those with spontaneous remission and those requiring treatment.

Common Variants in One-Carbon Metabolism Genes (, , ) and Depression in Gynecologic Cancers.

We investigated the association between methylenetetrahydrofolate reductase (gene 677C>T, rs1801133), 5-methyltetrahydrofolate-homocysteine methyltransferase ( 2756A>G, rs1805087), and methylenetetrahydrofolate dehydrogenase, cyclohydrolase and formyltetrahydrofolate synthetase 1 (gene 1958G>A, rs2236225)-well-studied functional variants involved in one-carbon metabolism-and gynecologic cancer risk, and the interaction between these polymorphisms and depression. A total of 200 gynecologic cancer cases and 240 healthy controls were recruited to participate in this study. Three single-nucleotide variants (SNVs) (rs1801133, rs1805087, rs2236225) were genotyped using the PCR-restriction fragment length polymorphism method.

Expression of ABCA1 Transporter and LXRA/LXRB Receptors in Placenta of Women with Late Onset Preeclampsia.

Background: Appropriate levels of cholesterol are necessary for the mother and developing fetus, but theirexcess may cause preeclampsia. The ABCA1 transporter mediates the secretion of cholesterol and is highly regulated at the transcriptional level via the nuclear liver X receptors (LXRs).

Methods: Sixteen preeclamptic and 39 normotensives healthy women with uncomplicated pregnancies were involved in the case-control study.

Low placental angiotensin-converting enzyme expression is related to fetal small for gestational age but not to metabolic control in type 1 diabetic pregnancies.

The maternal renin-angiotensin system is involved in blood pressure control and plays a crucial role in fetoplacental nutrition. Pre-gestational type 1 diabetes (PGDM) leads to serious pregnancy complications. We thus performed a longitudinal study to analyse the association of maternal angiotensin-converting enzyme (ACE) serum levels and placental mRNA expression with fetal newborns gestational weight in type 1 diabetes mellitus (T1DM) women.

Genetic variants of progesterone receptor in etiology of preterm delivery.

Objectives: Preterm delivery (PTD) accounts for around 11% of pregnancies worldwide. Unfortunately, no diagnostic indicator, specific mechanism or genetic predisposition has yet been identified. One of the hypotheses suggest local or functional progesterone decrease as a potential reason for preterm uterine contractions leading to preterm delivery.

Polymorphisms of fibronectin-1 (rs3796123; rs1968510; rs10202709; rs6725958; and rs35343655) are not associated with bronchopulmonary dysplasia in preterm infants.

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that mainly affects premature newborns. Many different factors, increasingly genetic, are involved in the pathogenesis of BPD. The aim of the study is to investigate the possible influence of fibronectin SNP on the occurrence of BPD.

The role of galectins in obstetrics with particular emphasis on premature preterm rupture of membranes.

Premature rupture of membranes (pPROM) affects about 4% of pregnancies and remains the main cause of preterm delivery (PTD). We currently lack a method for screening patients at high risk of pPROM as well as causal treatment for this yet not fully understood pathology of pregnancy. Promising, potential markers are proteins from a family of lectins-galectins.

The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was performed to examine the maternal , , , and polymorphisms.

The importance of the UGT1A1 variants in the development of osteopenia and osteoporosis in postmenopausal women.

The UDP-glucuronosyltransferase 1A1 (UGT1A1) is involved in the process of estrogen conjugation and elimination. The aim of the study was to analyze whether the UGT1A1 genetic variants are associated with the development of osteopenia and osteoporosis in postmenopausal women. The analysis of the rs4148323 (UGT1A1*6) and rs3064744 (UGT1A1*28) variants in the UGT1A1 gene was conducted using real-time PCR.

Plant Preparations and Compounds with Activities against Biofilms Formed by spp.

Fungi from the genus are very important human and animal pathogens. Many strains can produce biofilms, which inhibit the activity of antifungal drugs and increase the tolerance or resistance to them as well. Clinically, this process leads to persistent infections and increased mortality.

Vitamin D3 and its receptor in selected obstetrical complications.

Vitamin D3 (VD3) and its steroidal nuclear receptor are necessary for proper development of a pregnancy. They play a key role in implantation, modulate the mother's immune response to the developing fetus, influence the final development of a placenta, and regulate blood pressure and glucose tolerance. VD3 deficiency can lead to the occurrence of obstetric complications such as recurrent miscarriages, preeclampsia, intrauterine growth restriction, gestational diabetes and preterm labor.

The importance of NFκB1 rs4648068 and RUNX2 rs7771980 polymorphisms in bone metabolism of postmenopausal Polish women.

Objectives: Osteoporosis is a multifactorial disease that causes a loss of bone density. However, genetic factors play an increasingly important role in its development. To thoroughly understand the molecular mechanisms, polymorphic variants of genes candidate for osteoporosis are still being sought.

Plant Phenolics and Extracts in Animal Models of Preeclampsia and Clinical Trials-Review of Perspectives for Novel Therapies.

The current health requirements set the direction in pharmacological research, especially as regards diseases that require improvement of existing therapeutic regimens. Such diseases include preeclampsia, which is a hypertensive disorder of pregnancy during which there occurs progressive increasing activation of the immune system through elevation of pro-inflammatory cytokines and antiangiogenic factors, which is dangerous for the mother and fetus. A promising field of research for new drugs to treat this disease is the study of natural phenolic compounds of plant origin and herbal extracts, which are complex matrices of chemical compounds with broad biological activities.

Combined Effects of Methyldopa and Flavonoids on the Expression of Selected Factors Related to Inflammatory Processes and Vascular Diseases in Human Placenta Cells-An In Vitro Study.

The aim of the study was to investigate combined effects of flavonoids (apigenin, baicalein, chrysin, quercetin, and scutellarin) and methyldopa on the expression of selected proinflammatory and vascular factors in vitro for prediction of their action in pregnancy-induced hypertension. The research was conducted on a trophoblast-derived human choriocarcinoma cell line and a primary human umbilical vein endothelial cell line. Cytotoxicity of compounds in selected concentrations (20, 40, and 100 µmol) was measured using the MTT test and the concentration of 40 µmol was selected for further analysis.

Vitamin D receptor gene polymorphisms and haplotypes in the etiology of recurrent miscarriages.

A few years ago it was shown that disturbed metabolism of the vitamin D/receptor (VD/VDR) complex may be important in the etiology of spontaneous abortion, as well as in the etiology of recurrent miscarriages (RM). The goal of this study was to investigate the association between four maternal VDR polymorphisms as well as haplotypes settings and RM occurrence in a Polish population of women in reproductive age. A total of 230 women were recruited to this study (110 with RM, 120 consecutively recruited age-matched healthy women with at least two full-term pregnancies and with no history of miscarriages).

FokI vitamin D receptor polymorphism as a protective factor in intrahepatic cholestasis of pregnancy.

Objectives: Intrahepatic cholestasis in pregnancy (ICP) is a pregnancy-specific liver disorder. Its etiology is not fully understood. Increasing evidence indicates the important role of vitamin D and the vitamin D receptor (VDR) in this disorder.
