Ma et al. [20] demonstrated that METTL14 positively regulates the primary miRNA 126 (miR126) in an m6A-dependent manner by interacting with microprocessor complex subunit DiGeorge syndrome critical region 8 (DGCR8), and Ma et al. concluded that METTL14 can inhibit liver cancer metastasis. This evidence concerns the gene DGCR8 and liver cancer.
