Exosomal miR-4443 can reduce the expression level of methyltransferase-like 3 (METTL3) by targeting METTL3, and increase the level of FSP1 by N6-methyladenosine (m6A) methylation to inhibit ferroptosis and make NSCLC cells resistant to CDDP [151]. This evidence concerns the gene METTL3 and non-small cell lung carcinoma.
