Among the identified genes, 19 genes (ABCA2, ABCA3, ABCA4, ABCC1, ABCD1, CYP7A1, DIO2, EFHC1, FADS1, FADS2, GNPAT, KLF1, LIPE, NPC1, PEX6, PFKM, SLC29A1, SLC35B2, and SLC51B) and 7 genes (ACSL1, AKR1D1, ALDH8A1, BBOX1, CYP39A1, SLC27A5, and SLCO1B3) were upregulated in the tumor and nontumor samples, respectively (P < 0.05) (Figures 1(b) and 1(c)). Here, KLF1 is linked to neoplasm.
