Smac: Its role in apoptosis induction and use in lung cancer diagnosis and treatment.
Apoptosis is a conserved and regulated cell suicide process, the malfunction of which is closely linked with carcinogenesis. Caspases control the induction of apoptosis through an enzymatic cascade that can be activated by both the mitochondrial and death receptor pathways. Smac is a mitochondrial protein that interacts with Inhibitor of Apoptosis Proteins (IAPs) and, upon apoptotic stimuli, is released into the cytoplasm to inhibit the capase-binding activity of IAPs. Smac plays key roles in both the diagnosis and treatment of cancer, especially lung cancer. Our review will focus on the roles of Smac in lung carcinogenesis and cancer progression and its relevance in lung cancer treatment.
