Additionally, lysine acetyltransferase 2 A (KAT2A)-mediated H3K27 acetylation activates METTL3, promoting cancer metastasis by activating early growth response-1 (EGR1)/Snail signaling in a YTHDF3-dependent manner and revealing a susceptibility to METTL3 blockade in esophageal squamous cell carcinoma. Here, METTL3 is linked to cancer.
