FOXM1 and renal fibrosis: To observe the effects of FoxM1 on expressions of Wnts and renal fibrosis‐related genes, UUO mice were treated with FoxM1 inhibitor Siomycin A. The result showed that Siomycin A did not exhibit obvious effects on the expression of FoxM1 in sham‐operated kidneys, but dramatically abrogated the increase in FoxM1 in obstructed kidneys (Figure 7A,B).
