CR-activated cell cycle periodic genes in our study are directly or indirectly involved in tumorigenesis pathways, drive cancer cell proliferation, and aggressiveness (RRM2, ACSL3, RBBP8, KMO, FKBP5), drug resistance (ABCC5), and modulate chemosensitivity (FKBP5) (references in Table S2A). This evidence concerns the gene ABCC5 and cancer.
