Abstract
Plasma membranes were isolated from the cerebral cortex of control and chronic ethanol-treated rat brains. Analysis of protein composition by SDS-PAGE and by two-dimensional gel electrophoresis (IEF-SDS-PAGE) revealed significant differences in the membrane protein patterns between control and ethanol-treated rat cerebral cortices, indicating the loss of several proteins in membranes from ethanol-treated rat brains. Plasma membrane-associated protein species are categorized into ethanol-sensitive and -insensitive proteins, based on their response to ethanol. This study reports that ethanol depletes certain intrinsic proteins of membranes that might be responsible for plasma membrane disruption by ethanol.
