ERBB2 and invasive breast carcinoma: In the present study, we include analysis of TUG1 expression in 796 invasive breast carcinoma samples and 105 normal samples of RNA sequencing (RNA-seq) datasets from The Cancer Genome Atlas (TCGA), and describe that TUG1 expression is increased in HER2-enriched and basal-like subtypes compared to luminal A. Additionally, TUG1 expression is associated with overall survival in HER2-enriched patients.
