HQD downregulated the expression of the Smad1 protein in the kidneys of db/db mice. A. The protein expression levels of P-Smad1/5/9, Smad1 and Smad4 in the kidney cortex by Western blot assay. B. Statistical results of the expression level of Smad1, Values are mean ± SEM (n = 3), *P < 0.05, compared with db/m group; ##P < 0.05, compared with db/db group. *P < 0.05 vs. db/m, #P < 0.05 vs. db/db by one-way ANOVA with Tukey's post doc analysis
