چکیده

BACKGROUND The physiological demands of pregnancy on the maternal cardiovascular system can catapult women into a metabolic syndrome that predisposes to atherosclerosis in later life. We sought to identify the nature of the epigenomic changes associated with the increased cardiovascular disease (CVD) risk in adult women following pre-eclampsia. FINDINGS We assessed the genome wide epigenetic profile by methyl-C sequencing of monozygotic parous twin sister pairs discordant for a severe variant of pre-eclampsia. In the adult twin sisters at risk for CVD as a consequence of a complicated pregnancy, a set of 12 differentially methylated regions with at least 50% difference in methylation percentage and the same directional change was found to be shared between the affected twin sisters and significantly different compared to their unaffected monozygous sisters. CONCLUSION The current epigenetic marker set will permit targeted analysis of differentially methylated regions potentially related to CVD risk in large cohorts of adult women following complicated pregnancies.

Post-translational changes of histones, methylation level, and ERβ protein level in the cumulus cell genome of infertile women with endometriosis

Background: Endometriosis (which affects up to 50% of infertile women) is one of the major causes impacting female infertility. Endometriosis, defined as the presence of endometrial glands and stroma outside the uterine tissue, causes a wide range of functional disorders in the process of follicular development and changes in the follicular milieu, resulting in the formation of an incompetent o...

10-Year cardiovascular event risks for women who experienced hypertensive disorders in late pregnancy: the HyRAS study

BACKGROUND Cardiovascular disease is the cause of death in 32% of women in the Netherlands. Prediction of an individual's risk for cardiovascular disease is difficult, in particular in younger women due to low sensitive and specific tests for these women. 10% to 15% of all pregnancies are complicated by hypertensive disorders, the vast majority of which develop only after 36 weeks of gestation....

Evaluation of epigenetic changes of liver tissue induced by oral administration of Titanium dioxide nanoparticles and possible protective role of Nigella Sativa oil, in adult male albino rats

Objective (s): Titanium dioxide nanoparticles (TiO2 NPs) have been recognized as biologically inert material and have been used in a multitude of applications. Nevertheless, the negative impact on the human health is not yet well understood. Aim of the work: The study attempted to evaluate the epigenetic changes of the genome, in the form of DNA methylation in liver tissue samples, resulting fr...

Intergenerational factors: a missing link for preeclampsia, fetal growth restriction, and cardiovascular disease?

Preeclampsia and fetal growth restriction (FGR) are 2 obstetric syndromes that are generally associated with increased perinatal and maternal morbidities. Preeclampsia is defined as the onset of hypertension and proteinuria after 20 weeks gestation, and it complicates 3% to 5% of all pregnancies. FGR is defined as a birth weight below the fifth or 10th percentile for gestational age, and it can...
