Endothelin-1 Downregulates Sulfur Dioxide/Aspartate Aminotransferase Pathway via Reactive Oxygen Species to Promote the Proliferation and Migration of Vascular Smooth Muscle Cells

Figure 1

ET-1 downregulated the SO2/AAT pathway in primary VSMCs. In situ fluorescent staining (blue) detection of endogenous SO2 in primary VSMCs and quantified average fluorescence intensity by Image J. Fluorescent signal intensity reflects SO2 levels (a). Protein expression of AAT1 and AAT2 in primary VSMCs (b, c). AAT activity in VSMCs (d). Results are expressed as (). , vs. control. AAT1: aspartate aminotransferase 1; AAT2: aspartate aminotransferase 2; ET-1: endothelin-1; VSMCs: vascular smooth muscle cells.
