BRWLDA – bi-random walks for predicting lncRNA-disease associations

lncrna

Increasing efforts have been done to figure out the association between lncRNAs and complex diseases. Many computational models construct various lncRNA similarity networks, disease similarity networks, along with known lncRNA-disease associations to infer novel associations. However, most of them neglect the structural difference between lncRNAs network and diseases network, hierarchical relationships between diseases and pattern of newly discovered associations. In ...

LncFunNet – an integrated computational framework for identification of functional long noncoding RNAs

lncRNA

Long noncoding RNAs (lncRNAs) are key regulators of diverse cellular processes. Recent advances in high-throughput sequencing have allowed for an unprecedented discovery of novel lncRNAs. To identify functional lncRNAs from thousands of candidates for further functional validation is still a challenging task. Here, researchers from the Chinese University of Hong Kong present a novel computational framework, lncFunNet (lncRNA Functional inference ...

High-throughput annotation of full-length long noncoding RNAs with Capture Long-Read Sequencing (CLS)

lncrna

Accurate annotations of genes and their transcripts is a foundation of genomics, but no annotation technique presently combines throughput and accuracy. As a result, current reference gene collections remain far from complete: many genes models are fragmentary, while thousands more remain uncatalogued, particularly for long non coding RNAs (lncRNAs). To accelerate lncRNA annotation, the GENCODE consortium has developed RNA Capture ...

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 ...

AnnoLnc – a web server for systematically annotating novel human lncRNAs

lncRNA

Long noncoding RNAs (lncRNAs) have been shown to play essential roles in almost every important biological process through multiple mechanisms. Although the repertoire of human lncRNAs has rapidly expanded, their biological function and regulation remain largely elusive, calling for a systematic and integrative annotation tool. Here researchers from Peking University present AnnoLnc, a one-stop portal for systematically annotating novel human ...

Structural and Functional Annotation of Long Noncoding RNAs

lncrna

Protein-coding RNAs represent only a small fraction of the transcriptional output in higher eukaryotes. The remaining RNA species encompass a broad range of molecular functions and regulatory roles, a consequence of the structural polyvalence of RNA polymers. Albeit several classes of small noncoding RNAs are relatively well characterized, the accessibility of affordable high-throughput sequencing is generating a wealth of novel, ...

LDAP – a web server for lncRNA-disease association prediction

lncRNA

Increasing evidences have demonstrated that long noncoding RNAs (lncRNAs) play important roles in many human diseases. Therefore, predicting novel lncRNA-disease associations would contribute to dissect the complex mechanisms of disease pathogenesis. Some computational methods have been developed to infer lncRNA-disease associations. However, most of these methods infer lncRNA-disease associations only based on single data resource. Researchers at Central South University, ...

CHART – Mapping Long Noncoding RNA Chromatin Occupancy Using Capture Hybridization Analysis of RNA Targets

lncRNA

Capture Hybridization Analysis of RNA Targets (CHART) has recently been developed to map the genome-wide binding profile of chromatin-associated RNAs. This protocol uses a small number of 22-28 nucleotide biotinylated antisense oligonucleotides, complementary to regions of the target RNA that are accessible for hybridization, to purify RNAs from a cross-linked chromatin extract. RNA-chromatin complexes are next immobilized on beads, washed, ...

COME – a robust coding potential calculation tool for lncRNA identification and characterization

lncrna

Recent genomic studies suggest that novel long non-coding RNAs (lncRNAs) are specifically expressed and far outnumber annotated lncRNA sequences. To identify and characterize novel lncRNAs in RNA sequencing data from new samples, researchers at Tsinghua University have developed COME, a coding potential calculation tool based on multiple features. It integrates multiple sequence-derived and experiment-based features using a decompose-compose method, which ...

Functional annotation of noncoding variants and prioritization of cancer-associated lncRNAs in lung cancer

lncRNA

Multiple computational tools have been widely applied to the detection of coding driver mutations in cancer; however, the prioritization of pathogenic non-coding variants remains a difficult and demanding task. The present study was performed to distinguish non-coding disease-causing mutations from neutral ones, and to prioritize potential cancer-associated long non-coding RNAs (lncRNAs) with a logistic regression model in lung cancer. A ...
