LNC942 directly bound to METTL14 and promoted the expression of METTL14 protein through a specific binding domain (+176 to +265), resulting in the regulation of m6A methylation of C-X-C motif chemokine receptor 4 (CXCR4) and cytochrome P450 family 1 subfamily B member 1 (CYP1B) to stabilize their expression and translation and mediate the onset and development of breast cancer (Sun et al., 2020). This evidence concerns the gene METTL14 and breast carcinoma.
