Mechanical force

Mechanical force is **not a molecule or receptor**, but rather a physical phenomenon—such as tension, compression, shear stress, or pressure—that acts on cells and tissues. In biology and medicine, mechanical forces are fundamental regulators of cellular behavior through the process of mechanotransduction—the conversion of physical stimuli into biochemical signals. Cells sense these forces via specialized structures like mechanosensitive ion channels, integrins (adhesion molecules), cytoskeletal elements (actin filaments), and connections to the extracellular matrix. These interactions influence essential processes including cell migration, proliferation, differentiation, morphogenesis during development, tissue maintenance/remodeling in adults—and play roles in various diseases when dysregulated[1][4][6][8]. While mechanical forces are central to many physiological processes and pathologies—including cancer progression/metastasis and cardiovascular disease—they themselves are not considered therapeutic targets; instead the molecular sensors that detect them may be targeted for therapy. **Note:** "Mechanical force" is not itself a druggable target such as an enzyme or receptor; it is an external stimulus affecting biological systems via other molecular entities. Therefore this entry should be flagged as incorrect for use as a canonical therapeutic target name[1][4][6].
