Study workflow. RNA and DNA were simultaneously extracted from 23 breast cancer ER+/HER2− tumors and their paired adjacent non-malignant tissues. Strand-specific paired-end RNA sequencing and comparative genomic hybridization (CGH) were performed. Quality control steps and RNA-Seq validation were performed and led to the elimination of one patient due to poor strand specificity in this sample. This strategy allowed the study of the differential expression of ncNATs and PCTs between tumors and non-malignant tissues and performance of differential correlation analysis of ncNAT/PCT pairs. Three lists of genes with deregulated ncNAT expression in tumors that could potentially affect the corresponding PC expression were extracted, and their coding genes were subjected to survival analysis with an external cohort (TCGA).
