In total, 19 candidate genes (ACSS1, AK5, ALCAM, CHRD, CLDN1, CLDN16, GALNT10, HERC5, LAMB1, NFE2L3, OSTF1, PGM2, PODXL, PRKD3, SLC4A8, THBS1, CPT1A, ATP1B1, ABCB1) were confirmed according to our previously mentioned criteria (Figure 1A); among them, CPT1A, ATP1B1, ABCB1 were considered as PRGs in ovarian cancer. This evidence concerns the gene SLC4A8 and ovarian carcinoma.
