They investigated the effects of ethanol on the IGF-I system with the involvement of JNK1/2 activity and ADH by using each chemical inhibitor in primary cultured rat hepatocytes. The results indicate that ethanol inducedp-JNK1/2 activation is associated with the IGF-I system and cell viability in hepatocytes. Furthermore, alcohol dehydrogenase is involved in the relationship between ethanol-induced inactivation of p-JNK1/2 and the changes of the IGF-I system and cell viability.
