1 Four days of ethanol exposure enhanced carbachol-stimulated c-fos mRNA expression, analyzed with Northern blot, and Fos/AP-1 binding activity, measured with gel mobility super shift assay. Carbachol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
2 Pre-incubation with muscarinic antagonists or the protein kinase C inhibitor GF109203X demonstrated that, in both control and ethanol-treated cells, carbachol-induced c-fos expression was mediated via muscarinic M1 receptors and to a large extent through protein kinase C. However, phorbol ester-induced c-fos expression was unaffected in ethanol-treated cells. Carbachol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens

4 Acute exposure to ethanol caused a suppression of both carbachol- and phorbol ester-stimulated c-fos expression. Carbachol Fos proto-oncogene, AP-1 transcription factor subunit Homo sapiens
