The pre-clinical phase was integrated using a transcriptome BC cell line analysis, from which we identified an expression profile of lncRNAs that are expressed in luminal BC cell lines, such as GATA3-AS1 and LINC01016, and we also identified lncRNAs with expression specificity in luminal A tumors, such as LINC01016 and VIPR1-AS1, which are expressed only in luminal B cell lines and are novel lncRNAs related to the luminal phenotype. The gene discussed is GATA3; the disease is breast cancer.
