Figures 2B, C show the differences in the expression of m6A-related lncRNAs between 406 tumor tissues and 19 tumor-adjacent normal pairs from the TCGA dataset. Except for RAP2C-AS1, AC025280.1, ATP1B3-AS1, AC087286.2, AC012568.1, AC007686.3 and BDNF-AS, the other m6A-related lncRNAs were highly expressed in BC tissues (P < 0.05). The gene discussed is RAP2C; the disease is breast cancer.
