Spinal microglia activation is one of the pathologic mechanisms involved in post-operative pain, which results from surgical injuries in skin, fascia, muscle and small nerves innervating these tissues. Recent research has shown that neuregulin-1 (NRG1) and its receptor erythroblastosis oncogene B (ErbB) family mediate microglia proliferation and chemotaxis contributing to ...

Poly(ADP-ribose) polymerase 1 (PARP1) contributes to fibrosis in several disease models. Recent in vivo data indicate that loss of PARP1 attenuates renal fibrosis and inflammation independent on transforming growth factor-β (TGF-β); however, the role of PARP1 in kidney tubular cells in response to tubulointerstitial fibrosis remains to be defined. Here, ...

Myocardin is well known to play a key role in development of cardiomyocyte hypertrophy. But the exact molecular mechanism regulating myocardin stability and transactivity to affect cardiomyocyte hypertrophy has not been studied clearly. We now report that NF-κB (p65) can inhibit myocardin-induced cardiomyocyte hypertrophy. Then we explore the molecular mechanism ...

The vast majority of mammalian DNA does not encode for proteins but instead is transcribed into noncoding (nc)RNAs having diverse regulatory functions. The poorly characterized subclass of long ncRNAs (lncRNAs) can epigenetically regulate protein-coding genes by interacting locally in cis or distally in trans. A few reports have implicated specific ...

Ethanol exposure during pregnancy is an established cause of birth defects, including neurodevelopmental defects. Most adult neurons are produced during the second trimester-equivalent period. The fetal neural stem cells (NSCs) that generate these neurons are an important but poorly understood target for teratogenesis. A cohort of miRNAs, including miR-153, may ...

Inflammation is commonly associated with preterm birth. In non-gestational tissues, the cellular inhibitor of apoptosis protein (cIAP) 1 and 2, independent of their role in apoptosis, have emerged as important regulators of inflammation. There is, however, no data on the effect of human labour on the expression of cIAPs in ...

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 ...

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 ...

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 ...
