Inverted repeat Alu elements in the human lincRNA-p21 adopt a conserved secondary structure that regulates RNA function

leftarm

LincRNA-p21 is a long intergenic non-coding RNA (lincRNA) involved in the p53-mediated stress response. Yale University researchers sequenced the human lincRNA-p21 (hLincRNA-p21) and found that it has a single exon that includes inverted repeat Alu elements (IRAlus). Sense and antisense Alu elements fold independently of one another into a secondary structure that is conserved in lincRNA-p21 among primates. Moreover, the ...

Long noncoding RNA lincRNA-EPS as a repressor of inflammatory responses

lncRNA

Long intergenic noncoding RNAs (lincRNAs) are important regulators of gene expression. Although lincRNAs are expressed in immune cells, their functions in immunity are largely unexplored. Here, researchers at the University of Massachusetts Medical School identify an immunoregulatory lincRNA, lincRNA-EPS, that is precisely regulated in macrophages to control the expression of immune response genes (IRGs). Transcriptome analysis of macrophages from lincRNA-EPS-deficient ...

lincRNAs linked to increased children’s risk of blood infection

lncRNA

A team led by Oxford University has identified genes that make certain children more susceptible to invasive bacterial infections by performing a large genome-wide association study in African children. Bacteraemia, bacterial infection of the bloodstream, is a major cause of illness and death in sub-Saharan Africa but little is known about whether human genetics play a part. The leading bacterial ...

Tissue-Specific RNA-Seq in Human Evoked Inflammation Identifies Blood and Adipose LincRNA Signatures

Inappropriate transcriptional activation of innate immunity is a pathological feature of several cardiometabolic disorders, but little is known about inflammatory modulation of long intergenic noncoding RNAs (lincRNAs) in disease-relevant human tissues. Researchers at the University of Pennsylvania applied deep RNA sequencing (>500 million filtered reads per sample) to blood and adipose during low-dose experimental endotoxemia (lipopolysaccharide) in a healthy human, ...

lincRNAs are required for life

lncRNA

Many studies are uncovering functional roles for long noncoding RNAs (lncRNAs), yet few have been tested for in vivo relevance through genetic ablation in animal models. To investigate the functional relevance of lncRNAs in various physiological conditions, a team led by researchers at Harvard University have developed a collection of 18 lncRNA knockout strains in which the locus is maintained transcriptionally ...

Genome-wide survey by ChIP-seq reveals YY1 regulation of lincRNAs in skeletal myogenesis

lncRNA

Skeletal muscle differentiation is orchestrated by a network of transcription factors, epigenetic regulators, and non-coding RNAs. The transcription factor Yin Yang 1 (YY1) silences multiple target genes in myoblasts (MBs) by recruiting Ezh2 (Enhancer of Zeste Homologue2). To elucidate genome-wide YY1 binding in MBs, we performed chromatin immunoprecipitation (ChIP)-seq and found 1820 specific binding sites in MBs with a large ...

Featured Long Non-coding RNA – lincRNA-Cox2

lincRNA

An inducible program of inflammatory gene expression is central to antimicrobial defenses. Signal-dependent activation of transcription factors, transcriptional co-regulators, and chromatin modifying factors collaborate to control this response. Here, researchers from University of Massachusetts Medical School identify a long noncoding RNA that acts as a key regulator of this inflammatory response. Pattern recognition receptors such as the Toll-like receptors induce ...
