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 ...

The Xist lncRNA Exploits Three-Dimensional Genome Architecture to Spread Across the X Chromosome

lncRNA

Mammalian genomes encode thousands of large noncoding RNAs (lncRNAs), many of which regulate gene expression, interact with chromatin regulatory complexes, and are thought to play a role in localizing these complexes to target loci across the genome. A paradigm for this class of lncRNAs is Xist, which orchestrates mammalian X-chromosome inactivation (XCI) by coating and silencing one X chromosome in ...

Ribosome Profiling Provides Evidence that Large Noncoding RNAs Do Not Encode Proteins

Large noncoding RNAs are emerging as an important component in cellular regulation. Considerable evidence indicates that these transcripts act directly as functional RNAs rather than through an encoded protein product. However, a recent study of ribosome occupancy reported that many large intergenic ncRNAs (lincRNAs) are bound by ribosomes, raising the possibility that they are translated into proteins. Here, researchers from ...

The Future of lncRNAs with Dr. John Rinn

from Epigenie.com Dr. John L. Rinn from Harvard University and the Broad Institute (Harvard and MIT) is a prominent researcher in long non-coding RNAs (lncRNAs) and agreed to sit down and discuss his perspective on the intersection of lncRNA and epigenetics. EpiGenie: You’ve mentioned that you feel knockout models are going to play a key role in the next phase of ...
