The functional role of long non-coding RNAs and epigenetics

Long non-coding RNAs (lncRNAs) are non-protein coding transcripts longer than 200 nucleotides. The post-transcriptional regulation is influenced by these lncRNAs by interfering with the microRNA pathways, involving in diverse cellular processes. The regulation of gene expression by lncRNAs at the epigenetic level, transcriptional and post-transcriptional level have been well known and widely studied. Recent recognition that lncRNAs make effects in many biological and pathological processes such as stem cell pluripotency, neurogenesis, oncogenesis and etc. This review focuses on the functional roles of lncRNAs in epigenetics and related research progress are summarized.

Long non-coding RNAs in cancer: implications for personalized therapy

lncRNA

Long non-coding RNAs (lncRNAs, pseudogenes and circRNAs) have recently come into light as powerful players in cancer pathogenesis and it is becoming increasingly clear that they have the potential of greatly contributing to the spread and success of personalized cancer medicine. In this concise review, the authors briefly:

  1. Introduce these three classes of long non-coding RNAs.
  2. Discuss their applications as diagnostic and prognostic biomarkers.
  3. Describe their appeal as targets and as drugs,
  4. Point out the limitations that still lie ahead of their definitive entry into clinical practice.

Non-coding RNA – Zooming in on lncRNA functions

lncRNALong non-coding RNAs (lncRNAs) are emerging as important regulators of gene expression; however, in contrast to transcription factors, their functional domain architecture remains poorly understood. Now, a new method has been developed to simultaneously map RNA–RNA, RNA–DNA and RNA–protein interactions at the level of individual RNA domains with increased sensitivity.

Quinn et al. developed a method called domain-specific chromatin isolation by RNA purification (dChIRP), in which several antisense oligonucleotide pools are used to target specific domains of lncRNAs. In this method, cells are subjected to fixation, crosslinking and sonication, and the resultant sheared chromatin is hybridized to the biotinylated oligonucleotide pools to recover chromatin fragments containing specific lncRNA domains of interest. The RNA, DNA and protein components associated with the lncRNA domains can then be analysed separately.

LncRNA: A link between RNA and cancer

Unraveling the gene expression networks governing cancer initiation and development is essential while remains largely uncompleted. With the innovations in RNA-seq technologies and computational biology, long noncoding RNAs (lncRNAs) are being identified and characterized at a rapid pace. Recent findings reveal that lncRNAs are implicated in serial steps of cancer development. These lncRNAs interact with DNA, RNA, protein molecules and/or their combinations, acting as an essential regulator in chromatin organization, transcriptional and post-transcriptional regulation. Their misexpression confers the cancer cell capacities for tumor initiation, growth, and metastasis. The review here will emphasize their aberrant expression and function in cancer, and the roles in cancer diagnosis and therapy will be also discussed.
