How is signal transduction related to carcinogenesis?

Signal transduction refers to the process by which cells respond to external signals through a series of molecular events, often leading to changes in gene expression and cellular behavior. In carcinogenesis, dysregulation of these signaling pathways can lead to uncontrolled cell proliferation, evasion of apoptosis, and enhanced survival, contributing to tumor development and progression. Mutations in key signaling molecules or receptors can drive oncogenic processes, making understanding these pathways crucial for developing targeted cancer therapies. Thus, aberrant signal transduction plays a pivotal role in the initiation and advancement of cancer.
