MTOR activation in proximal tubules during UUO is inhibited by autophagy deficiency in PT-Atg7 knockout mice. Animals and their treatment were the same as described in Fig. 4. (A) Representative images of immunoblot analysis of phospho-RPS6KB1 and RPS6KB1. PPIB was used as a loading control. (B) Densitometric analysis of phospho-RPS6KB1 signals. After normalization with RPS6KB1 and PPIB, the protein signal of PT-Atg7 FC sham was arbitrarily set as 1, and the signals of other conditions were normalized with PT-Atg7 FC sham to calculate fold changes. Data are expressed as mean ± SD. *, P < 0.05, significantly different from PT-Atg7 FC sham group; #, P < 0.05, significantly different from the relevant PT-Atg7 FC group.
