Sulfur Dioxide Alleviates Aortic Dissection Through Inhibiting Vascular Smooth Muscle Cell Phenotype Switch, Migration, and Proliferation via miR-184-3p/Cyp26b1 Axis.

Abstract excerpt

Aims: Abnormal migration and proliferation of vascular smooth muscle cells (VSMCs) are considered early events in the onset of thoracic aortic dissection (TAD). Endogenous sulfur dioxide (SO2), primarily produced by aspartate aminotransferase (AAT1) in mammals, has been reported to inhibit the migration and proliferation of VSMCs. However, the role of SO2 in the development of TAD remains unclear. Results:...
