We found that (1) Diabetic mice exhibited severe fibrosis by BSA injection when compared to BSA injected control mice associated with induction of EMT program, (2) the TENE treatment ameliorated the proximal tubular damage and tubulointerstitial fibrosis induced by the BSA injection in the control and diabetic mice, (3) the TENE treatment suppressed the EMT program induced by the BSA injection in the diabetic mice by increasing anti-EMT miRs and (4) The crosstalk among DPP-4, integrin β1 and CAV1 was TGF-β/smad3 signaling dependent. The gene discussed is SMAD3; the disease is fibrosis.
