Then, the correlation analysis between LDB1 expression and survival related genes' expression in CRC was analyzed by the public cancer database GEPIA, and we found that LDB1 expression was positively correlated with CCNA1, BCL2 and BCLW (Figures 2A–C), but negatively correlated with the pro-apoptotic signals BID, BAX and BAK (Figures 2D–F). This evidence concerns the gene LDB1 and cancer.
