SLC26A4 and breast cancer: They also proposed six lncRNAs with differential histone modifications at enhancers to be used as prognostic biomarkers of the basal subtype of BC (LINC00393, RP1-140K8.5, KB-1836B5.1, CASC11, AC020916.2, and AC005162.1) and three lncRNAs with differential DNA methylation in enhancers or promoters (CTC-303L1.2, SLC26A4-AS1, and RP11-738B7.1) as prognostic biomarkers of the luminal subtype.
