Smad7 protein expression in each group by Western blot. (a) Western blot strip chart. (b) The gray graph shows the relative statistical values of Smad7 for each group. Compared with the NC group, Smad7 expression decreased in the experimental groups, especially in the diabetic nephropathy group, with a subsequent increase in the MH and ML groups, and a more pronounced increase in the MH group compared with the ML group. ^▲ P < 0.01 versus NC group, ^● P < 0.01 versus diabetic nephropathy group, and *P < 0.05 versus ML group.
