Bioinformatics for Novel Long Intergenic Noncoding RNA (lincRNA) Identification

lncRNA

Long intergenic noncoding RNAs (lincRNAs) , which are larger than 200 nucleotides and transcribed from the intergenic regions of protein coding genes, have been shown by accumulating findings to be widely expressed and extensively functional in many cellular processes. Nevertheless, given their cell/tissue-specificity, there is a need of identifying novel lincRNAs in a given system. To fulfill this purpose, researchers ...

Inheritable and Precise Large Genomic Deletions of Non-Coding RNA Genes in Zebrafish Using TALENs

lncRNA

Transcription activator-like effector nucleases (TALENs) have so far been applied to disrupt protein-coding genes which constitute only 2–3% of the genome in animals. The majority (70–90%) of the animal genome is actually transcribed as non-coding RNAs (ncRNAs), yet the lack of efficient tools to knockout ncRNA genes hinders studies on their in vivo functions. Here a team led by researchers ...

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 ...

Targeting long non-coding RNAs in cancers: Progress and prospects

lncRNA

Pervasive transcription occurs in the human genome to generate thousands of RNA transcripts, and accumulating evidence suggested that the RNA molecules, without protein coding ability, have important roles in diverse biological functions. Long non-coding RNA (lncRNA), with size larger than 200nt, is a new class of the non-coding RNA that contributes to cancer development and progression. Roles for several lncRNAs ...

iSeeRNA: identification of long intergenic non-coding RNA transcripts from RNA-Seq data

iSeeRNA

Long intergenic non-coding RNAs (lincRNAs) are emerging as a novel class of non-coding RNAs and potent gene regulators. High-throughput RNA-sequencing combined with de novo assembly promises quantity discovery of novel transcripts. However, the identification of lincRNAs from thousands of assembled transcripts is still challenging due to the difficulties of separating them from protein coding transcripts (PCTs). A team of scientists ...
