Abstract: Use of p55? as a therapeutic target for aortic dissection (AD) is provided, belonging to the technical field of biomedicine. Over-expression of the p55? inhibits formation of the AD and degradation of elastic fibers in mice induced by ?-aminopropionitrile fumarate (BAPN); whereas knockdown of the p55? 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 p55? plays a role by maintaining phenotypic switching of the VSMCs, and knocking down the p55? promotes phenotypic switching of the VSMCs from a contractile phenotype to a synthetic phenotype. The p55? 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.

Abstract: Use of a serine/arginine-rich splicing factor 1 (SRSF1) as a therapeutic target for aortic dissection is provided, which belonging to the technical field of biomedicine. The SRSF1 can be used as a target to screen a drug for preventing and/or treating aortic dissection. SRSF1 expression is upregulated in both ?-aminopropionitrile (BAPN)-induced aortic dissection model mice and aortic dissection patients. Mice with SRSF1 knockdown in vascular smooth muscle cells (VSMCs) are less susceptible to aortic dissection and elastic fiber degradation induced by BAPN. Mice with high expression of SRSF1 in VSMCs are more susceptible to aortic dissection and elastic fiber degradation induced by BAPN. Mechanistically, the SRSF1 can regulate the inflammatory phenotype of vascular smooth muscle and promote the degradation of vascular extracellular matrix. Knocking down the SRSF1 may improve the above phenomenon, thereby providing a new target for the treatment of aortic dissection.
