Significant enrichment of RNA binding protein sites across some lncRNA classes

Long non-coding RNAs (lncRNAs), are being reported to be extensively involved in diverse regulatory roles and have exhibited numerous disease associations. LncRNAs modulate their function through interaction with other biomolecules in the cell including DNA, RNA, and proteins. The availability of genome-scale experimental datasets of RNA binding proteins (RBP) motivated us to understand the role of lncRNAs in terms of ...

PLPIHS – prediction of lncRNA-protein interactions using HeteSim scores

lncRNA

Massive studies have indicated that long non-coding RNAs (lncRNAs) are critical for the regulation of cellular biological processes by binding with RNA-related proteins. However, only a few experimentally supported lncRNA-protein associations have been reported. Existing network-based methods are typically focused on intrinsic features of lncRNA and protein but ignore the information implicit in the topologies of biological networks associated with ...

Long Non-coding RNAs in Gastric Cancer: A True Relationship or miR Chance?

Long non-coding RNAs (lncRNAs) are gradually drawing the attention of the cancer research community due to their pivotal involvement in tumorigenesis and tumor progression. These non-protein coding, >200 nucleotides long transcripts are aberrantly expressed in the majority of human malignancies, including gastric cancer (GC). The discovery that lncRNAs are severely deregulated across different human malignancies has prompted the pursuit of ...

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 ...

Researchers develop new CRISPR sgRNA design tool, demonstrate efficient CRISPR deletion of an enhancer and exonic fragment of the lncRNA MALAT1

lncRNA

CRISPR-Cas9 technology can be used to engineer precise genomic deletions with pairs of single guide RNAs (sgRNAs). This approach has been widely adopted for diverse applications, from disease modelling of individual loci, to parallelized loss-of-function screens of thousands of regulatory elements. However, no solution has been presented for the unique bioinformatic design requirements of CRISPR deletion. Researchers from the Centre for ...

ExInAtor – driver lncRNA discovery using mutational patterns in tumour DNA

lncRNA

Long noncoding RNAs (lncRNAs) represent a vast unexplored genetic space that may hold missing drivers of tumourigenesis, but few such “driver lncRNAs” are known. Until now, they have been discovered through changes in expression, leading to problems in distinguishing between causative roles and passenger effects. Researchers at the CRG – Barcelona Institute of Science and Technology have developed a different ...

Researchers describe the first use of spherical nucleic acids as nanoparticle platform for regulating lncRNAs in cells

Emerging evidence indicates that long noncoding RNAs (lncRNAs) are actively involved in a number of developmental and tumorigenic processes. Here, Northwestern University researchers describe the first successful use of spherical nucleic acids as an effective nanoparticle platform for regulating lncRNAs in cells; specifically, for the targeted knockdown of the nuclear-retained metastasis associated lung adenocarcinoma transcript 1 (Malat1), a key oncogenic ...
