Microtubule dynamics disruption

Microtubule dynamics disruption refers to interference with the normal polymerization and depolymerization of microtubules—cytoskeletal filaments essential for cell division, intracellular transport, and maintenance of cell shape. This process is the pharmacological target of several anti-cancer drugs, as rapidly dividing cells (such as cancer cells) rely on precise control of microtubule dynamics for proper mitosis. Drugs targeting microtubule dynamics either stabilize microtubules (e.g., taxanes) and prevent depolymerization or destabilize them (e.g., vinca alkaloids, colchicine), leading to cell cycle arrest and apoptosis of proliferating cells. Targeting this process is clinically important but presents safety concerns, especially regarding neurotoxicity and resistance. This entry is not a valid molecule/receptor for structured target annotation, but describes a pharmacological strategy used in modern therapeutics.
