METTL14 and hepatocellular carcinoma: Bioinformatics analysis based on TCGA database data has revealed that METTL14 may participate in the malignant progression of HCC by regulating m6A-modified genes, including cysteine sulfinic acid decarboxylase (CSAD), glutamate oxaloacetate transaminase 2 (GOT2), and suppressor of cytokine signaling 2 (SOCS2) (Li et al., 2020).
