Silencing Myo1b in senescent cells ameliorates endothelial dysfunctions and reverses endothelial senescence phenotypic changes such as senescence-associated-β-galactosidase activity, cyclin-dependent kinase inhibitor p21WAF1, expression of vascular adhesion molecule-1 (VCAM1) and intercellular adhesion molecule-1 (ICAM1), and the senescence-associated cytokines. The gene discussed is VCAM1; the disease is endothelial dysfunction.
