UTA researchers discover connection between low oxygen levels and the lncRNA HOTAIR

lncrna

University of Texas at Arlington researchers have established a link between hypoxia, a condition that reduces the flow of oxygen to tissues, and HOTAIR, a noncoding RNA or molecule that has been implicated in several types of cancer. RNA, or ribonucleic acid, is present in all living cells. Its primary role is to carry instructions from DNA. In a study ...

Targeting lncRNA to reduce heart failure in pulmonary hypertension

lncrna

An article published in Experimental Biology and Medicine identifies a new signaling pathway that promotes heart failure in pulmonary hypertension.  The study, led by Dr. Matthias Brock, from the Division of Pulmonology, University Hospital of Zurich, University of Zurich in Switzerland, reports that inhibition of MALAT1, a long noncoding RNA, reduces heart hypertrophy in mice with pulmonary hypertension. Pulmonary hypertension ...

Long non-coding RNA MALAT1 is induced by hypoxia

lncRNA

Long thought to be “junk DNA”, in recent years it has become clear that a substantial fraction of intergenic genomic DNA is actually transcribed, forming long noncoding RNA (lncRNA). Like mRNA, lncRNA can also be spliced, capped, and polyadenylated, affecting a multitude of biological processes. While the molecular mechanisms underlying the function of lncRNAs have just begun to be elucidated, ...

RNA-Seq reveals long noncoding RNAs response to hypoxia in the endothelial cell

lncRNA

Long noncoding RNAs (lncRNAs) are non-protein coding RNAs regulating gene expression. Although for some lncRNAs a relevant role in hypoxic endothelium has been shown, the regulation and function of lncRNAs is still largely unknown in the vascular physio-pathology. Taking advantage of next-generation sequencing techniques, researchers at the Policlinico San Donato-IRCCS investigated transcriptomic changes induced by endothelial cell exposure to hypoxia. ...

AR promotes RCC via lncRNA interaction

lncRNA

The androgen receptor (AR) regulates progression of renal cell carcinoma (RCC) via a mechanism dependent on VHL status and hypoxia, according to data published in Oncogene. RCC is associated with inactivation of the von Hippel–Lindau (VHL) suppressor protein, which targets hypoxia-inducible factors HIF-1α and HIF-2α. VHL inactivation is associated with a good prognosis, but the mechanisms of this effect are ...
