Ethanol promotes apoptosis in rat ovarian granulosa cells via the Bcl-2 family dependent intrinsic apoptotic pathway.

This study recruited rat ovarian granulosa cells, the primary effector of ovary, to investigate the effects of ethanol on cell apoptosis and explore potential mechanism. Ovarian granulosa cells treated with ethanol for three hours manifested observable reduction in cell viability and apparent apoptosis. In the presence of 200 and 300 mmol/l of ethanol, the percentages of apoptotic cells increased to 33% and 36%, respectively. In addition, apoptosis related caspase-3 activity was elevated with increasing concentrations of ethanol, suggesting a dose dependent effect. Furthermore, high concentrations of ethanol significantly disturbed the transcriptional and translational regulation of anti-apoptotic Bcl-2 and pro-apoptotic Bax, which are the two key members of Bcl-2 family tightly involved in intrinsic apoptotic pathway. These results indicated that ethanol promotes apoptosis in rat ovarian granulosa cells, possibly via the intrinsic apoptotic pathway. PMID: 29412806 [PubMed - in process]

AbstractThe role of norepinephrine (NE) in the development of alcohol use disorder (AUD) has been studied over the past several decades. However, the NE system has been largely ignored for many years as a potential target for medication development for AUD. More recently, preclinical and clinical studies have demonstrated the potential value of targeting NE signaling for developing new pharmacological treatments for AUD. This review contributes to a special issue ofPsychopharmacology focused on promising targets for alcohol addiction. Specifically, this review coalesces preclinical and clinical neuroscience that re-evaluat...

Publication date: 15 May 2018 Source:Materials Letters, Volume 219 Author(s): Guoxia Lv, Jing Wang, Zhiqiang Shi, Liping Fan The initial multilayer-structure two-dimensional transition metal carbide MXene (as-Ti3C2Tx) are synthesized by selectively etching Mn+1AXn in HF, and the surface of MXene adhere to some functional groups. Intercalation and delamination by ultrasonication in alcohol or DMSO (dimethyl sulfoxide) produce less lamellar structure of resultant (d-Ti3C2Tx) and change the surface circumstance. This fabricated fewer-sheets samples not only improve the electrical conductibility, specific area, but also reduc...
