Through its mechanism, YTHDF3 increases the translation of m6A-enriched transcripts associated with cerebral metastasis of breast cancer, such as ST6 N-Acetylgalactosaminide Alpha-2,6-Sialyltransferase 5 (ST6GALNAC5), Gap Junction Protein Alpha 1 (GJA1), and EGFR. This evidence concerns the gene GJA1 and breast carcinoma.
