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 ...

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 ...

Slncky – evolutionary analysis across mammals reveals distinct classes of long non-coding RNAs

lncRNA

Recent advances in transcriptome sequencing have enabled the discovery of thousands of long non-coding RNAs (lncRNAs) across many species. Though several lncRNAs have been shown to play important roles in diverse biological processes, the functions and mechanisms of most lncRNAs remain unknown. Two significant obstacles lie between transcriptome sequencing and functional characterization of lncRNAs: identifying truly non-coding genes from de ...

lncRNA-screen – an interactive platform for computationally screening long non-coding RNAs in large genomics datasets

lncRNA

Long non-coding RNAs (lncRNAs) have emerged as a class of factors that are important for regulating development and cancer. Computational prediction of lncRNAs from ultra-deep RNA sequencing has been successful in identifying candidate lncRNAs. However, the complexity of handling and integrating different types of genomics data poses significant challenges to experimental laboratories that lack extensive genomics expertise. To address this ...

Next-Generation Sequencing Analysis of Long Noncoding RNAs

lncRNA

Next-generation sequencing approaches, in particular RNA-seq, provide a genome-wide expression profiling allowing the identification of novel and rare transcripts such as long noncoding RNAs (lncRNA). Many RNA-seq studies have now been performed aimed at the characterization of lncRNAs and their possible involvement in cell development and differentiation in different organisms, cell types, and tissues. Researchers from the National Institute of ...

CRISPR Deletion-Based Screen Identifies Functional Long Non-Coding RNAs

lncRNA

from GenomeWeb by Andrew Han – A new study published today in Nature Biotechnology turns high-throughput CRISPR/Cas9-based knockout screening towards long non-coding RNAs to find functional elements. A Chinese-American collaboration, led by first author Shiyou Zhu and senior author Wei Li  of Peking University and first author Wensheng Wei and senior author Xiaole Shirley Liu of the Dana-Farber Cancer Institute, ...

lncScore – alignment-free identification of long noncoding RNA from assembled novel transcripts

lncRNA

RNA-Seq based transcriptome assembly has been widely used to identify novel lncRNAs. However, the best-performing transcript reconstruction methods merely identified 21% of full-length protein-coding transcripts from H. sapiens. Those partial-length protein-coding transcripts are more likely to be classified as lncRNAs due to their incomplete CDS, leading to higher false positive rate for lncRNA identification. Furthermore, potential sequencing or assembly error ...

Identification and function annotation of long intervening noncoding RNAs

RNA-seq technology offers the promise of rapid comprehensive discovery of long intervening noncoding RNAs (lincRNAs). Basic tools such as Tophat and Cufflinks have been widely used for RNA-seq assembly. However, advanced bioinformatics methodologies that allow in-depth analysis of lincRNAs are lacking. Here, researchers from the Chinese Academy of Sciences describe a computational protocol that is especially designed for the identification ...

Quantitative gene profiling of long noncoding RNAs with targeted RNA sequencing

lncRNA

The majority of the human genome is differentially expressed across a wide dynamic range to produce a spectrum of protein-coding and noncoding RNAs, generating a transcriptome of unexpected scale and complexity. These features present a challenge for gene-expression profiling with qRT-PCR and RNA-seq. qRT-PCR is ill suited for discovering genes, resolving alternative splicing or characterizing whole transcriptomes. RNA-seq measures global ...
