The unsuspected functions of lncRNAs

The cell microenvironment (1)

A large majority of the genome, about 98%, is considered noncoding. However, the ENCODE project states that 80% of the genome has a function (1). LncRNAs (long non-coding RNAs) are RNAs that do not encode proteins and are constituted with more than 200 nucleotides (2).
But then what are they used for?

LncRNAs have no function as messenger RNA to be translated into protein, but they are involved in many cellular mechanisms. Here is a non-exhaustive list:

  1. Gene regulation (activation and repression of transcription).
  2. Chromatin structure regulation.
  3. Post-transcriptomic regulation.
  4. Regulation of signaling pathway.
LncRNA assays: Perform high-throughput analysis of lncRNA expression profile to explore their involvement in your samples by qPCR arrays.

lncRNAs in Cancer Phenotypes

Long Noncoding RNAs in Cancer Pathways. Cancer Cell. 2016

In 2015, Iyer MK, et al. (3) classified nearly 58000 lncRNA whose role is little known. However, the same team demonstrates that lncRNAs are regulators of the physiology of certain tissues and that they are involved in many pathologies such as cancer, cardiovascular diseases or autoimmune diseases. Their numerous roles and their ubiquity in the human body make them very efficient biomarkers.

In 2016, Schmitt AM and Chang HY (4) identified 499 lncRNAs as playing a key role in cell growth. In addition, 89% of those who had a role for a given cell type had no functional role in another cell type.
