Figure 11. Validation of circRNAs and TRIM2 in ccRCC tissues and cell lines. (A) Bar plot for the relative expression of five hub circ_RNAs in ccRCC tissues and normal tissues. (B) Bar plot for the relative expression of 8 circ_RNAs in ccRCC cell lines and normal 293T cell line. (C, D) Immunohistochemical analysis of TRIM2 in ccRCC tissues. (E, F) Immunohistochemical analysis of TRIM2 in normal kidney tissues.
