Tan IIA down-regulates TGF-β1, TSP-1, Grp78 and CHOP expression in the renal tissues of the diabetic rats. (A) Immunohistochemical analysis of TGF-β1, TSP-1, Grp78 and CHOP expression in the renal tissues among five groups and the pooled data from ten sections for each group is summarized. Scale bar: 50 μm (×400). (B, C) The expression levels of Grp78 (B) and CHOP (C) from different treatment groups were determined by qRT-PCR. N = 10; *P <0.05 and **P <0.01.
