Cell proliferation, differentiation, and apoptosis (programmes cell death) are tightly regulated in healthy tissues by a variety of external signals via membrane-spanning receptors that activate intracellular signal transduction pathways. Some cancer cells acquire genetic mutations that dysregulate these pathways, resulting in malignant cells that uncontrollably proliferate and no longer respond to the signals that normally activate apotosis.1
