SUMO1 and IgA glomerulonephritis: In a cell model of IgA nephropathy, the inhibition of SUMOylation by 2 μmol/L ginkgolic acid C15:1 could reduce SUMO1 expression, promote autophagy, and lessen cell proliferation of human mesangial cells, indicating a reno-protective effect of ginkgolic acid in IgA nephropathy.
