Non-small cell lung cancer (WP4255)

Non-small cell lung cancer (NSCLC) represents 85% of lung cancer and is defined as any type of epithelial lung cancer that is NOT small cell carcinoma, including squamous cell (SCC), adeno (AC) and large-cell carcinoma. Mutations in NSCLC: * KRAS (mutated in ~29% of NSCLC patients) inactivates its GTPase activity and the p21-RAS protein continuously transmits growth signals to the nucleus. * Mutations or overexpression of EGFR (~22% of NSCLC patients) leads to increased proliferation. * The abnormal fusion of EML4-ALK (~5% of NSCLC patients) leads to constitutive ALK activation, which causes cell proliferation, invasion, and inhibition of apoptosis. * Inactivating mutation of p53 (~50% of NSCLC patients) leads to reduced apoptosis and proliferation. * The protein encoded by the p16INK4a, CDKN2A, inhibits formation of CDK-cyclin-D complexes by competitive binding of CDK4 and CDK6. p16INK4a is mutated in ~12% of NSCLC patients, which leads to a loss of this inhibitory effect. * RARB is a nuclear retinoic acid receptor whose function is often lost in NSCLC, leading to a loss of cell growth control.
