Core Tip

Core tip: Evasion of apoptosis has been established as a prominent hallmark of several human cancers, contributing to both tumor progression and chemo-resistance. In colorectal cancer development, the balance between the rates of cell growth and apoptosis that maintains intestinal epithelial cell homeostasis is impaired progressively. Recent studies indicated that failure of apoptosis may be an important factor in the evolution of colorectal cancer and its poor response to chemotherapy and radiation. We herein discussed the mechanisms of apoptosis, abnormal expression of apoptosis-related genes and future promises of apoptotic pathways as a therapeutic target for colorectal cancer chemoprevention and treatment.
