Background: Long noncoding RNAs (lncRNAs) play important roles in many physiological and pathological processes, this indicates that lncRNAs can serve as potential targets for gene therapy. Stable expression is a fundamental technology in the study of lncRNAs. The lentivirus is one of the most widely used delivery systems for stable expression.

Previous studies about the FOXA1 transcriptional network were mainly focused on protein-coding genes. Its regulatory network of long non-coding RNAs (lncRNAs) and their role in FOXA1 oncogenic activity remains unknown.

Although ER-regulated genes have been extensively investigated, little is known about roles of ER-regulated lncRNAs in breast cancer. Here, we conducted genome-wide study of ER-regulated lncRNAs by using RNA-seq, ChIP-seq and TCGA data.

Unlabelled: Several studies have shown that long non-coding RNAs (lncRNAs) may play an essential role in Epithelial-Mesenchymal Transition (EMT), which is an important step in tumor metastasis; however, little is known about the global change of lncRNA transcriptome during EMT. To investigate how lncRNA transcriptome alterations contribute to EMT progression regulation, we deep-sequenced the whole-transcriptome of MCF10A as the cells underwent TGF-β-induced EMT.
Results: Deep-sequencing results showed that the long RNA transcriptome of MCF10A had undergone global changes as early as 8h after treatment with TGF-β.
