Abstract:
:Chronic exposure of cultured canine cerebral vascular smooth muscle cells to ethanol (10-400 mM) for 1-5 days resulted in significant concentration-dependent elevation in resting intracellular free calcium ([Ca2+]i) levels. Preincubation of these cultured vascular cells with inhibitors of protein kinase C (PKC), staurosporine and H7, induced no apparent changes from the control resting levels of [Ca2+]i. However, the increases of [Ca2+]i due to ethanol treatment were attenuated markedly by staurosporine and H7. Our data suggest that activation of PKC plays an important role in ethanol's action in producing a sustained rise in [Ca2+]i in cerebral vascular smooth muscle cells. Activation of PKC could thus play a crucial role in the pathogenesis of alcohol-induced cerebral ischemia and stroke.

杂志文章abstract:BACKGROUND:The etiology of neurodegenerative disease remains unclear. Recently, SNP rs11868035, located in an intron of the sterol regulatory element binding factor (SREBF1) gene, was found to be associated with Parkinson's disease (PD) in a large European population in a genome-wide association study. To examine the p...
