Prenatal caffeine ingestion is one of the risk factors for intrauterine growth retardation (IUGR). Adrenal plays a pivotal role, mainly through steroidogenesis, in the regulation of intrauterine homeostasis and in fetal development and maturation. We have shown that prenatal caffeine ingestion can inhibit fetal adrenal corticosterone production, but the underlying ...

Eukaryotic cells carry out quality control (QC) over the processes of RNA biogenesis to inactivate or eliminate defective transcripts, and to avoid their production. In the case of protein-coding transcripts, the quality controls can sense defects in the assembly of mRNA-protein complexes, in the processing of the precursor mRNAs, and ...

Here, we investigated the effects of thrombin on matrix metalloproteinases (MMPs) and prostaglandin (PG) synthesis in fetal membranes. Thrombin activity was increased in human amnion from preterm deliveries. Treatment of mesenchymal, but not epithelial, cells with thrombin resulted in increased MMP-1 and MMP-9 mRNA and enzymatic activity. Thrombin also increased ...

Studies have showed that increase of placental expression of imprinted genes PHLDA2 may have a potential regulatory role in fetal IUGR (intrauterine growth restriction) in singleton. In this study, we investigate the expression level of PHLDA2 in placenta of monozygotic twins (MZT) with selective intrauterine growth restriction (sIUGR) and normal ...

We have previously identified sex-specific differences in the fetal-placental response to cortisol. Our recent studies suggest that this differential response to cortisol is driven by differences in glucocorticoid receptor (GR) protein function rather than through changes in gene transcription or protein expression. This study was designed to define whether the ...

Steroidogenic factor 1 (SF1; Ad4BP/NR5A1) plays key roles in gonadal development. Initially, the Sf1 gene is expressed in mouse fetal gonads of both sexes, but later is up-regulated in testes and down-regulated in ovaries. While Sf1 expression is activated and maintained by Wilms tumor 1 (WT1) and LIM homeobox 9 ...

Fetal growth involves highly complex molecular pathways. IGF2 is a key paternally expressed growth hormone that is critical for in utero growth in mice. Its role in human fetal growth has remained ambiguous, as it has only been studied in term tissues. Conversely the maternally expressed growth suppressor, PHLDA2, has ...

Recent advances reveal mRNA 3'end processing as a highly regulated process that fine-tunes posttranscriptional gene expression. This process can affect the site and/or the efficiency of 3'end processing, controlling the quality and the quantity of substrate mRNAs. The regulation of 3'end processing plays a central role in fundamental physiology such ...

Insulin-like growth factor 2 (IGF2), a developmentally regulated and maternally imprinted gene, is frequently overexpressed in pediatric cancers. Although loss of imprinting (LOI) at fetal promoters contributes to increased IGF2 in tumors, the magnitude of IGF2 expression suggests the involvement of additional regulatory mechanisms. A microRNA (miRNA) screen of primary ...

P-glycoprotein (P-gp), an efflux transporter encoded by the abcb1 gene, protects the developing fetal brain. Levels of P-gp in endothelial cells of the blood-brain barrier (BBB) increase dramatically during the period of peak brain growth. This is coincident with increased release of TGF-β1 by astrocytes and neurons. Although TGF-β1 has ...

Reduced monocyte human leukocyte antigen (mHLA)-DR surface expression in the late phase of sepsis is postulated as a general biomarker of sepsis-induced immunosuppression and an independent predictor of nosocomial infections.However, traditional monitoring of mHLA-DR by flow cytometry has disadvantages due to specific laboratory requirements. An mRNA-based HLA-DR monitoring by PCR ...

Germ cells are unique in undergoing meiosis to generate oocytes and sperm. In mammals, meiosis onset is before birth in females, or at puberty in males, and recent studies have uncovered several regulatory steps involved in initiating meiosis in each sex. Evidence suggests that retinoic acid (RA) induces expression of ...

The mechanisms that regulate the induction of term or preterm delivery are not fully understood. Infection is known to play a role in the induction of pro-inflammatory cascades in uteroplacental tissues associated with preterm pathological parturition. Similar, but not identical cascades are evident in term labor. In the current study ...

Cytotoxic T lymphocytes (CTLs) modified with chimeric antigen receptors (CAR) for adoptive immunotherapy of hematologic malignancies have demonstrated activity in early phase clinical trials. While CTLs bearing stably expressed CARs are efficacious and have potential long-term persistence, temporary expression of a CAR via RNA electroporation is also potentially efficacious in ...

Maternal obesity (MO) predisposes offspring to obesity and type 2 diabetes (T2D) despite poorly defined mechanisms. Zfp423 is the key transcription factor committing cells to the adipogenic lineage and with exceptionally dense CpG sites in its promoter. We hypothesized that MO enhances adipogenic differentiation during fetal development through inducing epigenetic ...

While differentiated cardiomyocytes proliferate prior to birth, adult cardiomyocytes in mammals exhibit relatively little proliferative activity. The T-box transcription factor Tbx20 is necessary and sufficient to promote prenatal cardiomyocyte proliferation, and Tbx20 also is required for adult cardiac homeostasis. The ability of Tbx20 to promote post-natal and adult cardiomyocyte proliferation ...

Preterm birth remains one of the most important issues facing perinatal medicine today, with chronic inflammation and/or infection being the biggest aetiological factor. The nucleotide oligomerization domain (NOD) intracellular molecules recognise a wide range of microbial products as well as other intracellular danger signals, thereby initiating inflammation through activation of ...

Children with Down syndrome (DS) develop a unique congenital clonal megakaryocytic proliferation disorder (transient myeloproliferative disorder -TMD). It is caused by an expansion of fetal megakaryocyte-erythroid progenitors (MEP) triggered by trisomy of chromosome 21 and further enhanced by the somatic acquisition of a mutation in GATA1. These mutations result in ...

Keloids are tumor-like skin scars that grow as a result of the aberrant healing of skin injuries, with no effective treatment. The molecular mechanism underlying keloid pathogenesis is still largely unknown. In this study, we compared microRNA (miRNA) expression profiles between keloid-derived fibroblasts and normal fibroblasts (including fetal and adult ...

Strategies to increase fetal hemoglobin (HbF) levels can ameliorate symptoms and improve the lives of β-hemoglobinopathy patients. While most studies have focused on induction of γ-globin gene expression as an approach to induce HbF, we hypothesized that post-transcriptional regulation of HbF plays an underappreciated yet important role in controlling HbF ...

Cardiac hypertrophy has been well-characterized at the level of transcription. During cardiac hypertrophy, genes normally expressed primarily during fetal heart development are re-expressed, and this fetal gene program is believed to be a critical component of the hypertrophic process. Recently, alternative splicing of mRNA transcripts has been shown to be ...
