However, although METTL3-m6A-CDCP1 axis can promote the proliferation and migration of SV-HUC-1 uroepithelial cells in vitro, injection of METTL3 or CDCP1-overexpressing SV-HUC-1 cells into immunodeficient mice did not induce tumor formation in vivo (data not shown). The gene discussed is METTL3; the disease is neoplasm.
