Acetaminophen (APAP) is a widely used analgesic and antipyretic that can lead to severe liver damage when taken at excessive doses. APAP toxicity results when cytochrome P450-generated APAP metabolites trigger an oxidative stress and covalently modify target proteins. APAP has also been reported to inhibit cells from completing S-phase through a cytochrome P450-independent mechanism, raising the possibility that APAP may directly suppress liver regeneration and repair. Here we show that APAP also inhibits entrance of Hepa 1-6 cells into the cell cycle by blocking a number of events associated with the G0-G1 transition. We have found that APAP inhibits serum growth factor activation of c-myc expression, NF-kappaB DNA binding, and Raf kinase. Therefore, the ability of APAP to inhibit passage of cells through both G1 and S phases might interfere with organ regeneration and thus exacerbate acute liver damage caused by APAP.
