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). Here, GJA1 is linked to breast carcinoma.
