Mettl3 is a downstream target of miR-193b-5p and is positively regulated by BLACAT2, so BLACAT2 promotes gastric cancer progression by regulating the miR-193b-5p/Mettl3 pathway.[96] In addition, it was found that LINC00240 suppresses the invasion of non-small cell lung cancer cells.[97] Mettl3 was found to be negatively regulated by miR-338-5p, and LINC00240 acts as a sponge for miR-338-5p to control the malignant phenotype of gastric cancer cells by regulating the miR-338-5p/Mettl3 axis. The gene discussed is LINC00958; the disease is gastric cancer.
