Abstract：
:We have used an in vitro system to monitor the effects of high levels of ammonia and ethanol on glial cells. Nuclei were isolated and the protein profiles examined by two-dimensional gel electrophoresis. Acute exposure of rat astrocyte cell cultures to ammonia or ethanol resulted in changes in cellular morphology and the level of some nuclear proteins. Glial fibrillary acidic protein (GFAP) levels remained constant under both treatments. Several nuclear proteins were increased specifically. Only one protein was visually detected which was unique to treatment with ammonia or ethanol. This protein (p2a) appeared only in the presence of ammonia. There were no changes in previously observed astrocyte-associated proteins (Silverman et al. Neurochem Int.12, 513-518, 1988). Two proteins appeared de novo upon either treatment with either ammonia or ethanol. These latter proteins had a molecular weight and pI profile similar to the major class of nuclear stress proteins (hsp70). However, results from immunoblot experiments clearly demonstrated that hsp70 was not induced in astroycte cultures following exposure to ammonia or ethanol.
