YTHDF3 enhanced the translation of m6A-enriched transcripts of ST6 beta-galactoside alpha-2, 6-sialyltransferase 5 (ST6GALNAC5), gap junction protein alpha 1 (GJA1), epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF), which promoted breast cancer metastasis to the brain (Chang et al., 2020). This evidence concerns the gene GJA1 and breast cancer.
