Use Of P55gamma As Therapeutic Target For Aortic Dissection (ad)

Abstract

Use of p55γ as a therapeutic target for aortic dissection (AD) is provided, belonging to the technical field of biomedicine. Over-expression of the p55γ inhibits formation of the AD and degradation of elastic fibers in mice induced by β-aminopropionitrile fumarate (BAPN); whereas knockdown of the p55γ in vascular smooth muscle cells (VSMCs) promotes the formation of the AD and the degradation of the elastic fibers induced by the BAPN. Mechanistically, the p55γ plays a role by maintaining phenotypic switching of the VSMCs, and knocking down the p55γ promotes phenotypic switching of the VSMCs from a contractile phenotype to a synthetic phenotype. The p55γ is used as a target in screening a drug for prevention and/or treatment of AD, such that a selected drug can effectively prevent and/or treat the AD, thus providing a new target for treating the AD.
