Compared to control lung tissues, 43 differentially expressed MMRGs were identified in lung cancer tissues, including 24 upregulated (ATP4A, ALDH3B2, ATP4B, ALDH3A1, CYP4A22-AS1, ADH1C, GAPDH, PKLR, PPAT, CPT1B, PFKP, PC, PFKP-DT, ALDH1L1, ADH4, GPI, ALDH8A1, ALDH18A1, ATP12A, GAPDHS, NDUFS6, OXCT2, CYC1, and ALDH1L2) and 19 downregulated MMRGs (ADH1B, ACADL, ADH1A, CYP4A26P, PPARG, ALDH1A2, ALDH2, ALDH3B1, CYP4A11, MDH1B, ACSBG1, ACSL4, CYP2U1, CYP4A22, CYP4A27P, ACSL1, PPARGC1A, ACAA2, and PFKFB2). Here, ATP12A is linked to lung cancer.
