AI Article Synopsis

  • Chromatin-enriched RNAs (cheRNAs) are a type of long noncoding RNAs that help regulate gene transcription by interacting with chromatin and influencing gene expression.
  • These RNAs can alter chromatin structure and recruit chromatin modifiers, playing a significant role in various diseases, especially tumors.
  • The review highlights the unexplored role of cheRNAs in cancer stem cells (CSCs) and their potential impact on tumor formation and treatment strategies.

Article Abstract

Chromatin-enriched RNAs (cheRNAs) constitute a special class of long noncoding RNAs (lncRNAs) that are enriched around chromatin and function to activate neighboring or distal gene transcription. Recent studies have shown that cheRNAs affect chromatin structure and gene expression by recruiting chromatin modifiers or acting as bridges between distal enhancers and promoters. The abnormal transcription of cheRNAs plays an important role in the occurrence of many diseases, particularly tumors. The critical effect of cancer stem cells (CSCs) on the formation and development of tumors is well known, but the function of cheRNAs in tumorigenesis, especially in CSC proliferation and stemness maintenance, is not yet fully understood. This review focuses on the mechanisms of cheRNAs in epigenetic regulation and chromatin conformation and discusses the way cheRNAs function in CSCs to deepen the understanding of tumorigenesis and provide novel insight to advance tumor-targeting therapy.

RNA species act as architectural scaffolds for nuclear structures including chromatin in eukaryotic cells. However, the composition and dynamics of tightly bound chromatin-associated RNAs during mitosis remains elusive. Here we report the identification of chromatin-enriched RNA (cheRNAs) by biochemical nuclear fractionation coupled with RNA sequencing in both interphase and mitotic phase of A549 and HeLa-S3 cell lines.

Article Synopsis
  • Plants can generate callus, a cell mass crucial for tissue regeneration, but the role of chromatin-enriched noncoding RNAs (cheRNAs) in this process is still unclear.
  • Recent research identified 2,284 cheRNAs during various stages of callus formation in rice, revealing their regulatory functions in gene expression and their importance for plant size and seed morphology.
  • These findings highlight cheRNAs' vital role in somatic cell regeneration and suggest they could be key targets for enhancing crop traits in the future.

Long noncoding RNAs (lncRNAs) localize in the cell nucleus and influence gene expression through a variety of molecular mechanisms. Chromatin-enriched RNAs (cheRNAs) are a unique class of lncRNAs that are tightly bound to chromatin and putatively function to locally cis-activate gene transcription. CheRNAs can be identified by biochemical fractionation of nuclear RNA followed by RNA sequencing, but until now, a rigorous analytic pipeline for nuclear RNA-seq has been lacking.

Chromatin-enriched lncRNAs: a novel class of enhancer RNAs.

Nat Struct Mol Biol

Long noncoding (lnc)RNAs are postulated to control diverse biological processes by modulating transcription, yet for most lncRNAs evidence supporting this function has been lacking. A new report describes the role of a novel class of lncRNAs—chromatin-associated enhancer RNAs or cheRNAs—in the regulation of proximal gene expression.
