Maternal emotional distress symptoms, including life satisfaction, anxiety and depressed mood, are worse in Severely Obese (SO) than lean pregnancy and may alter placental genes regulating fetal glucocorticoid exposure and placental growth. We hypothesised that the associations between increased maternal distress symptoms and changes in placental gene expression including IGF2 and genes regulat...

Asymmetric distribution of maternal mRNAs has not been well documented in zebrafish. Recently, we have shown that dazl mRNA is localized at the vegetal pole. Here we report a novel zebrafish gene, bruno-like (brul), which provides another example of vegetal mRNA localization. brul encodes an Elav-type RNA-binding protein that belongs to the Bruno-like family that includes mammalian CUG-BP, Xeno...

The Mos protein kinase is a key regulator of vertebrate oocyte maturation. Oocyte-specific Mos protein expression is subject to translational control. In the frog Xenopus, the translation of Mos protein requires the progesterone-induced polyadenylation of the maternal Mos mRNA, which is present in the oocyte cytoplasm. Both the Xenopus p42 mitogen-activated protein kinase (MAPK) and maturation-...

The objective of this study was to determine if levels of mRNA encoding cytosolic glutathione peroxidase (cGPx) and thioredoxin reductase (TrxR-1) change during fetal development, and if maternal Se intake during gestation affects the mRNA levels of these proteins. Prepubertal gilts (n = 24) were randomly assigned to either Se-adequate (0.39 ppm of Se; n = 12) or Se-deficient (0.05 ppm of Se; n...

BACKGROUND. The significant risks posed to mothers and fetuses by COVID-19 in pregnancy have sparked a worldwide debate surrounding the pros cons of antenatal SARS-CoV-2 inoculation, as we lack sufficient evidence regarding vaccine effectiveness pregnant women their offspring. We aimed provide substantial for effect BNT162b2 mRNA versus native infection on maternal humoral, well transplacentall...

Objective : The placental growth factor (PlGF) plays a crucial role in early and late pregnancy development. Pregestational type 1 diabetes (T1D) is complication that may lead to serious fetomaternal complications. Our study analyzed the association between PlGF mRNA expression metabolic control, fetal weight development women with T1D. Materials methods A cross-sectional on 65 pregnant T1D sin...

OBJECTIVE Noninvasive prenatal detection of trisomy 21 (T21) has been achieved by measuring the ratio of two alleles of a single nucleotide polymorphism in circulating placenta specific 4 (PLAC4) mRNA in maternal plasma with a few assays in recent years. Our research is to explore the variations of PLAC4 mRNA expression level in maternal plasma with normal pregnancies in second trimester, which...

We have studied protein synthesis in the viable hybrid Xenopus laevis (female) X Xenopus borealis (male) using 2D gel electrophoresis. Fourteen borealis-specific proteins were studied. Two of these proteins appeared by the gastrula stage, five in the gastrula and the rest later. Where homologous laevis proteins were tentatively identified, androgenetic haploid hybrids were used to study whether...

Objective(s): Maternal high-fat diet (HFD) consumption has been linked to metabolic disorders and reproductive dysfunctions in offspring. Troxerutin (TRO) has anti-hyperlipidemic, anti-oxidant, and anti-inflammatory effects. This study examined the effects of TRO on apelin-13, its receptors mRNA and ovarian histological changes in the offspring of HFD fed rats. <...
