PHF5A and colorectal carcinoma: ETBF‐infected cells could significantly down‐regulate miR‐149‐3p depending on the METTL14‐mediated N6‐methyladenosine methylation, which further increased the PHD finger protein 5A (PHF5A, a splicing modulator interacting with SF3b complex) expression, and promoted the RNA AS of Lysine acetyltransferase 2A (KAT2A) in CRC cells.
