Furthermore, the RAD51 mRNA expression data were downloaded from the TCGA data portal to analyze the prognostic value of the RAD51 expression; the overall survival analysis of RAD51 expression did not show prognostic significance in colorectal cancer (p = 0.496; Figure 2A), colon cancer (p = 0.821; Figure 2B), and rectal cancer (p = 0.392; Figure 2C) in the TCGA data. This evidence concerns the gene RAD51 and rectal cancer.
