Long non-coding RNAs (lncRNAs) play diverse roles in physiological and pathological processes. Several lncRNAs have been suggested to modulate gene expression by guiding chromatin-modifying complexes to specific sites in the genome. However, besides the example of Xist, clear-cut evidence demonstrating this novel mode of regulation remains sparse. Here, we focus on HOTAIR, a lncRNA that is over...

Pancreatic cancer is one of the most deadly cancers with a poor prognosis. Though studies have implicated the roles of microRNAs in pancreatic cancer progression, little is known about the role of miR-613 in pancreatic cancer. In the present study, the expression of miR-613 was down-regulated in pancreatic cancer tissues and cancer cell lines. Down-regulation of miR-613 was positively correlate...

c-Myc is regarded as a transcription factor, but the basis for its function remains unclear. Here, we define a long noncoding RNA (lncRNA)/protein complex that mediates the transcriptional activation by c-Myc in breast cancer cells. Among 388 c-Myc target genes in human MCF-7 breast cancer cells, we found that their promoters could be occupied by the oncoprotein HBXIP. We confirmed that the HBX...

BACKGROUND HOX antisense transcript RNA (HOTAIR) is a 2148 nt long, intergenic, non-coding RNA molecule, which is reported to be highly expressed in many types of cancers. This meta-analysis summarizes its expression in cancer. METHODS We searched all eligible papers on the prognostic impact of HOTAIR in cancer from inception to 30 September 2015 in PubMed, CBMdisc, and the CNKI database. Onl...

Abstract Objective: To investigate the involvement of HOX transcript antisense RNA (HOTAIR) in injury renal tubular epithelial cells induced by high glucose. Results: In glucose‐induced HK‐2 cells, expression HOTAIR was upregulated, resulting suppressed cell proliferation. Meanwhile, upregulates pro‐apoptotic proteins Bax and cleaved caspase‐3, while downregulating anti‐apoptotic protein Bcl‐2....

This paper describes an extensible and scalable approach to indexing documents that is utilized within the Highly Organised Team of Agents for Information Retrieval (HOTAIR) architecture.

Cancer stem cells are associated with tumor recurrence. IKK is a protein kinase that is composed of IKKα, IKKβ, IKKγ. Herein, we demonstrate that IKKα plus IKKβ promoted and IKKγ inhibited liver cancer stem cell growth in vitro and in vivo. Mechanistically, IKKα plus IKKβ enhanced and IKKγ inhibited the interplay among HP1α, HP1β and HP1γ that competes for the interaction among HP1α, SUZ12, HEZ...

BACKGROUND Calycosin and genistein are the two main components of isoflavones. Previously, we reported that these compounds display antitumor activities in the breast cancer cell lines MCF-7 and T47D. In the present study, we investigated the mechanism of action of calycosin and genistein, and their respective efficacies as potential therapies for the treatment of breast carcinoma in the clinic...
