What Are the Functions of Signal Transduction Pathways?
Signal transduction pathways transmit signals from cell surface receptors to the nucleus, affecting gene expression and cell behavior. Dysregulation of these pathways can result in uncontrolled cell growth and cancer. Key pathways include the PI3K/AKT/mTOR pathway, the MAPK pathway, and the WNT pathway. Targeted therapies, such as PI3K inhibitors and BRAF inhibitors, aim to disrupt these abnormal signals.
