Extracellular vesicle associated long non-coding RNAs functionally enhance cell viability

Cells communicate with one another to create microenvironments and share resources. One avenue by which cells communicate is through the action of exosomes. Exosomes are extracellular vesicles that are released by one cell and taken up by neighbouring cells. But how exosomes instigate communication between cells has remained largely unknown. Researchers from the University of New South Wales present evidence ...

LncRNAs and miRNAs – potential biomarkers and therapeutic targets for prostate cancer

Prostate cancer (PCa) is the second lethal disease for men in western countries. Although androgen receptor (AR) signaling has been widely investigated, noncoding RNAs (ncRNAs), deficient of open reading frame, have also received considerable attention. Growing studies showed that the aberrant ncRNAs expression contributed to cell proliferation, metastasis and drug resistance in PCa. Therefore, therapeutically targeting ncRNAs may synergize androgen ...

KTCNlncDB – a first platform to investigate lncRNAs expressed in human keratoconus and non-keratoconus corneas

lncRNA

Keratoconus (KTCN, OMIM 148300) is a degenerative eye disorder characterized by progressive stromal thinning that leads to a conical shape of the cornea, resulting in optical aberrations and even loss of visual function. The biochemical background of the disease is poorly understood, which motivated researchers from the Medical University of Warsaw to perform RNA-Seq experiment, aimed at better characterizing the ...

LincSNP 2.0 – an updated database for linking disease-associated SNPs to human long non-coding RNAs

lncrna

Researchers from Harbin Medical University describe LincSNP 2.0, an updated database that is used specifically to store and annotate disease-associated single nucleotide polymorphisms (SNPs) in human long non-coding RNAs (lncRNAs) and their transcription factor binding sites (TFBSs). In LincSNP 2.0, the researchers have updated the database with more data and several new features, including: expanding disease-associated SNPs in human lncRNAs; ...

FEELnc – a tool for long non-coding RNA annotation

lncRNA

Whole transcriptome sequencing (RNA-seq) has become a standard for cataloguing and monitoring RNA populations. One of the main bottlenecks, however, is to correctly identify the different classes of RNAs among the plethora of reconstructed transcripts, particularly those that will be translated (mRNAs) from the class of long non-coding RNAs (lncRNAs). Here, researchers from University Rennes1 present FEELnc (FlExible Extraction of ...

Visualizing the secondary and tertiary architectural domains of lncRNA RepA

lncRNA

Long noncoding RNAs (lncRNAs) are important for gene expression, but little is known about their structures. RepA is a 1.6-kb mouse lncRNA comprising the same sequence as the 5′ region of Xist, including A and F repeats. It has been proposed to facilitate the initiation and spread of X-chromosome inactivation, although its exact role is poorly understood. To gain insight ...

LncPriCNet – Global Prioritizing Disease Candidate lncRNAs via a Multi-level Composite Network

lncRNA

LncRNAs play pivotal roles in many important biological processes, but research on the functions of lncRNAs in human disease is still in its infancy. Therefore, it is urgent to prioritize lncRNAs that are potentially associated with diseases. Researchers from the Shanghai Jiao Tong University have developed a novel algorithm, LncPriCNet, that uses a multi-level composite network to prioritize candidate lncRNAs ...

Human Pancreatic β Cell lncRNAs Control Cell-Specific Regulatory Networks

lncRNA

Recent studies have uncovered thousands of long non-coding RNAs (lncRNAs) in human pancreatic β cells. β cell lncRNAs are often cell type specific and exhibit dynamic regulation during differentiation or upon changing glucose concentrations. Although these features hint at a role of lncRNAs in β cell gene regulation and diabetes, the function of β cell lncRNAs remains largely unknown. In ...

Comparing Machine Learning Based Tools for Long Noncoding Transcripts Discrimination

lncRNA

Long noncoding RNA (lncRNA) is a kind of noncoding RNA with length more than 200 nucleotides, which aroused interest of people in recent years. Lots of studies have confirmed that human genome contains many thousands of lncRNAs which exert great influence over some critical regulators of cellular process. With the advent of high-throughput sequencing technologies, a great quantity of sequences ...
