Figure 2. P4HB protein expression was significantly higher in KIRC tissues in comparison with normal tissues, while GABRAPL1 protein expression was significantly lower. Representive IHC images of P4HB (A) and GABRAPL1 (B) in normal (left) and KIRC (middle) tissues. Images were downloaded from HPA Database. Statistical analyses of the protein expression levels of P4HB and GABRAPL1 according to the information of normal and KIRC tissues (right). * p<0.05; ** p<0.01.
