METTL3 can recognize the m6A modification of pri-miR-1246, and thus upregulate the expression of miR-1246, which inhibited CCNG2 to accelerate cell proliferation, migration, and invasion, but suppressed apoptosis of ovarian cancer cells, with the net effect of promoting the progression of ovarian cancer. The gene discussed is CCNG2; the disease is ovarian carcinoma.
