TLDR
The results suggest that lincRNAs may serve as scaffolds by providing binding surfaces to assemble select histone modification enzymes, thereby specifying the pattern of histone modifications on target genes.Abstract:
Long intergenic noncoding RNAs (lincRNAs) regulate chromatin states and epigenetic inheritance. Here, we show that the lincRNA HOTAIR serves as a scaffold for at least two distinct histone modification complexes. A 5' domain of HOTAIR binds polycomb repressive complex 2 (PRC2), whereas a 3' domain of HOTAIR binds the LSD1/CoREST/REST complex. The ability to tether two distinct complexes enables RNA-mediated assembly of PRC2 and LSD1 and coordinates targeting of PRC2 and LSD1 to chromatin for coupled histone H3 lysine 27 methylation and lysine 4 demethylation. Our results suggest that lincRNAs may serve as scaffolds by providing binding surfaces to assemble select histone modification enzymes, thereby specifying the pattern of histone modifications on target genes.read more

Regulation of chromatin by histone modifications
TL;DR: The known histone modifications are described, where they are found genomically and discussed and some of their functional consequences are discussed, concentrating mostly on transcription where the majority of characterisation has taken place.

Non-coding RNAs in human disease
TL;DR: Dysregulation of these ncRNAs is being found to have relevance not only to tumorigenesis, but also to neurological, cardiovascular, developmental and other diseases, and there is great interest in therapeutic strategies to counteract these perturbations.

TL;DR: These archetypes of lncRNA function may be a useful framework to consider how lncRNAs acquire properties as biological signal transducers and hint at their possible origins in evolution.

Genome Regulation by Long Noncoding RNAs
John L. Rinn,Howard Y. Chang +1 more
TL;DR: Long noncoding RNAs (lncRNAs) as discussed by the authors form extensive networks of ribonucleoprotein (RNP) complexes with numerous chromatin regulators and then target these enzymatic activities to appropriate locations in the genome.

TL;DR: The Gene Set Enrichment Analysis (GSEA) method as discussed by the authors focuses on gene sets, that is, groups of genes that share common biological function, chromosomal location, or regulation.

TL;DR: It is proposed that bivalent domains silence developmental genes in ES cells while keeping them poised for activation, highlighting the importance of DNA sequence in defining the initial epigenetic landscape and suggesting a novel chromatin-based mechanism for maintaining pluripotency.
