p38 MAP kinase: a convergence point in cancer therapy.

ABSTRACT

Recent studies show that activation of p38 mitogen-activated protein kinase (MAPK) results in cancer cell apoptosis initiated by retinoids, cisplatin and other chemotherapeutic agents. The observation that divergent therapies act through a common signal transduction pathway raises the possibility of developing new anti-cancer agents that lack the side-effects caused by events upstream of p38 MAPK. Here, we review p38-MAPK-mediated tumor cell apoptosis and implications for cancer therapeutics.
