Ethanol inhibition of L1-mediated cell adhesion may contribute to the spectrum of neurological, behavioral and morphological abnormalities associated with prenatal ethanol exposure. We showed previously that the neuroprotective peptides NAPVSIPQ (NAP) and SALLRSIPA (SAL) antagonize ethanol inhibition of L1 adhesion and prevent ethanol-induced growth(More)
Ethanol-induced apoptosis in selected cell populations is a major component of pathogenesis underlying ethanol-induced teratogenesis. However, there is a fundamental gap in understanding how ethanol leads to apoptosis in embryos. In this study, we investigate the role of seven in absentia homolog-1 (Siah1) protein, an E3 ubiquitin ligase, in ethanol-induced(More)
MicroRNAs are a class of small noncoding RNAs that have been implicated in regulation of a broad range of cellular and physiologic processes, including apoptosis. The objective of this study is to elucidate the roles of miR-125b in modulating ethanol-induced apoptosis in neural crest cells (NCCs) and mouse embryos. We found that treatment with ethanol(More)
BACKGROUND The Siberian salamander (Ranodon sibiricus), distributed in geographically isolated areas of Central Asia, is an ideal alpine species for studies of conservation and phylogeography. However, there are few data regarding the genetic diversity in R. sibiricus populations. METHODOLOGY/PRINCIPAL FINDINGS We used two genetic markers (mtDNA and(More)
Previous studies have demonstrated that maternal ethanol exposure induces a moderate increase in Nrf2 protein expression in mouse embryos. Pretreatment with the Nrf2 inducer, 3H-1, 2-dithiole-3-thione (D3T), significantly increases the Nrf2 protein levels and prevents apoptosis in ethanol-exposed embryos. The present study, using PC12 cells, was designed to(More)
Fibroblast growth factor 21 (FGF21) is a hepatokine that regulates glucose and lipid metabolism in the liver. We sought to determine the role of FGF21 in hepatic steatosis in mice exposed to chronic alcohol treatment and to discern underlying mechanisms. Male FGF21 knockout (FGF21 KO) and control (WT) mice were divided into groups that were fed either the(More)
Seven in absentia homolog 1 (Siah1) is one of the E3 ubiquitin ligases and plays a key role in regulating target protein degradation. This study was designed to test the hypothesis that Siah1 mediates ethanol-induced apoptosis in NCCs through p38 MAPK-mediated activation of the p53 signaling pathway. We found that exposure of NCCs to ethanol resulted in the(More)
Reactive oxygen species (ROS) induce or protect cellular oxidative damage. ROS are also known to play an important role in apoptosis, autophagy, endoplasmic reticulum stress, mitochondrial dysfunction, cell migration, and invasion. This special issue presents the recent advances in basic research and association studies of some natural products and chemical(More)
