BECN1 and diabetes mellitus: We observed that both surgical trauma and DM significantly increased the expression levels of p‐mTOR and P62 (Figure 2A,B,D,E, p < 0.05) and decreased Beclin‐1 expression and the LC3‐II/LC3‐I ratio (Figure 2D, E, p < 0.05) on days 3 and 7 after surgery compared with those in the control group.
