Abstract

Cisplatin is a broadly prescribed anti-tumor agent for the treatment of diverse cancers. Therapy with cisplatin, however, is associated with various adverse effects including nephrotoxicity and ototoxicity. AMP kinase (AMPK), an evolutionarily conserved enzyme, functions as the fundamental regulator of energy homeostasis. While AMPK activation protects normal tissues against cisplatin-induced toxicities, its impact in cancer is context-dependent and there is no single, uniform role for AMPK. On one hand, some report that AMPK activation augments cisplatin-induced apoptosis in cancer, while on the other hand, few reports indicate that AMPK activation rescues cancer cells from the cytotoxicity induced by cisplatin. Here we review the most salient signaling pathways regulated by AMPK with an emphasis on their relation to cisplatin toxicity and yet discuss context-dependent functions of AMPK in cancer.
