Zhao et al. analyzed the epigenetic changes of lncRNAs in three breast cancer subtypes and identified three DNA methylation-dysregulated lncRNAs (CTC-303L1.2, RP11-738B7.1, and SLC26A4-AS1) as prognostic biomarkers of the basal subtype (Zhao et al., 2021). The gene discussed is SLC26A4; the disease is breast cancer.
