Targeting extrinsic apoptosis in cancer: Challenges and opportunities

Apoptosis is a form of programmed cell death that plays a critical role in the regulation of various physiological and pathophysiological processes. Since apoptosis is typically disturbed in human cancers, therapeutic targeting of apoptosis represents a promising avenue for the development of novel therapeutic approaches. This strategy is particularly relevant, since many currently used anticancer therapies utilize apoptosis signaling pathways to exert their antitumor activities. A better understanding of these signaling networks and their deregulation in human cancers is anticipated to open new perspectives for the development of apoptosis-targeted therapies for the treatment of cancer.
