The fraction of AGE, RAGE, TGF-β1, TGF- β1 receptor, BDNF and TrkB in the different layers of the colon between two groups. In the different layers, the fraction of AGE, RAGE, TGF-β1 and TGF- β1 receptor was bigger whereas the fraction of BDNF and TrkB was smaller in the Diabetes group than in Control group. Compared with Control group: *P < 0.05, **P < 0.01.
