Cytoskeletal remodeling

Cytoskeletal remodeling is a highly dynamic biological process involving the continuous assembly, disassembly, and reorganization of the cellular framework, primarily composed of actin filaments, microtubules, and intermediate filaments [1][2]. This process is critical for fundamental cellular activities including migration, maintaining structural integrity, and executing cell division [2]. In oncology, aberrant cytoskeletal remodeling is a hallmark of metastasis, as it enables cancer cells to become motile and invade surrounding tissues [3]. In cardiovascular medicine, remodeling of the actin-myosin cytoskeleton in smooth muscle cells regulates vascular resistance and is a target for treating hypertension [4]. While 'Cytoskeletal remodeling' is a process rather than a single molecular target, many of its components—such as tubulin and Rho-associated protein kinase (ROCK)—serve as established therapeutic targets for drugs like taxanes and ROCK inhibitors [4][5]. However, because these structural proteins are essential for the survival of almost all cell types, therapeutic interventions often face a narrow window between efficacy and systemic toxicity [5].

Drugs targeting this process typically act by stabilizing or destabilizing protein polymers (such as microtubules or actin filaments) or by inhibiting upstream regulatory signaling molecules like Rho-associated protein kinase (ROCK) and other Rho GTPases [1][4].
