Activation of the JNK/activator protein-1 (AP-1)-signaling pathway is a common mediator of hepatocyte death from a variety of stimuli. Although the mechanism by which JNK or AP-1 promotes death is unknown, it results when activation of this signaling pathway is unusually prolonged. Although JNK/AP-1 mediates TNF-induced cell death at or above the level of the mitochondria, the ability of JNK/AP-1 to promote death from necrosis as well as apoptosis suggests that JNK/AP-1 may induce death by several mechanisms. Recognition of JNK/AP-1 signaling as a critical promoter of hepatocyte death raises the possibility that the therapeutic manipulation of this pathway may be effective in the treatment of human liver disease.
