Non-coding RNA networks in cancer.
TLDR
A deeper understanding of the complex networks of interactions that ncRNAs coordinate would provide a unique opportunity to design better therapeutic interventions.Abstract:
Thousands of unique non-coding RNA (ncRNA) sequences exist within cells. Work from the past decade has altered our perception of ncRNAs from 'junk' transcriptional products to functional regulatory molecules that mediate cellular processes including chromatin remodelling, transcription, post-transcriptional modifications and signal transduction. The networks in which ncRNAs engage can influence numerous molecular targets to drive specific cell biological responses and fates. Consequently, ncRNAs act as key regulators of physiological programmes in developmental and disease contexts. Particularly relevant in cancer, ncRNAs have been identified as oncogenic drivers and tumour suppressors in every major cancer type. Thus, a deeper understanding of the complex networks of interactions that ncRNAs coordinate would provide a unique opportunity to design better therapeutic interventions.read more

TL;DR: In this paper, the identification of lincRNAs (lincRNA-p21) that serve as a repressor in p53-dependent transcriptional responses was reported, and the observed transcriptional repression was mediated through the physical association with hnRNP-K at repressed genes and regulation of p53 mediates apoptosis.

The Role of Non-coding RNAs in Oncology
TL;DR: For decades, research into cancer biology focused on the involvement of protein-coding genes, but an explosion of studies into ncRNA biology has shown that they represent a diverse and prevalent group of RNAs, including both oncogenic molecules and those that work in a tumor suppressive manner.

Translation and functional roles of circular RNAs in human cancer.
TL;DR: The works on circRNA translation will open a hidden human proteome, and enhance us to understand the importance of circRNAs in human cancer, which has been poorly explored so far.

The C. elegans heterochronic gene lin-4 encodes small RNAs with antisense complementarity to lin-14
TL;DR: Two small lin-4 transcripts of approximately 22 and 61 nt were identified in C. elegans and found to contain sequences complementary to a repeated sequence element in the 3' untranslated region (UTR) of lin-14 mRNA, suggesting that lin- 4 regulates lin- 14 translation via an antisense RNA-RNA interaction.

TL;DR: It is found that a human circRNA, antisense to the cerebellar degeneration-related protein 1 transcript (CDR1as), is densely bound by microRNA (miRNA) effector complexes and harbours 63 conserved binding sites for the ancient miRNA miR-7.

TL;DR: This study serves as the first functional analysis of a naturally expressed circular RNA, ciRS-7, which contains more than 70 selectively conserved miRNA target sites, and is highly and widely associated with Argonaute proteins in a miR-7-dependent manner.

A ceRNA Hypothesis: The Rosetta Stone of a Hidden RNA Language?
TL;DR: It is proposed that this "competing endogenous RNA" (ceRNA) activity forms a large-scale regulatory network across the transcriptome, greatly expanding the functional genetic information in the human genome and playing important roles in pathological conditions, such as cancer.
