To further explore the expression values of FBXO7, RAD23A, and MKRN1 genes concerning CD8+ T cells in different cancers, the correlations of FBXO7, RAD23A, and MKRN1 expression values with CD8+ T cells in the TIMER database were next obtained and downloaded and visualized using the “ggplot “ R package for visualization. This evidence concerns the gene RAD23A and cancer.
