TLDR
Understanding this novel RNA crosstalk will lead to significant insight into gene regulatory networks and have implications in human development and disease.
Abstract
Recent reports have described an intricate interplay among diverse RNA species, including protein-coding messenger RNAs and non-coding RNAs such as long non-coding RNAs, pseudogenes and circular RNAs. These RNA transcripts act as competing endogenous RNAs (ceRNAs) or natural microRNA sponges — they communicate with and co-regulate each other by competing for binding to shared microRNAs, a family of small non-coding RNAs that are important post-transcriptional regulators of gene expression. Understanding this novel RNA crosstalk will lead to significant insight into gene regulatory networks and have implications in human development and disease.

Unique features of long non-coding RNA biogenesis and function

TL;DR: This Review describes special events in the lifetimes of lncRNAs — before, during and after transcription — and discusses how these events ultimately shape the unique characteristics and functional roles of lNCRNAs.

Long Noncoding RNAs in Cancer Pathways

TL;DR: It is understood that lncRNAs drive many important cancer phenotypes through their interactions with other cellular macromolecules including DNA, protein, and RNA, making these molecules attractive targets for therapeutic intervention in the fight against cancer.

Functional Classification and Experimental Dissection of Long Noncoding RNAs

TL;DR: This review categorizes lncRNA loci into those that regulate gene expression in cis versus those that perform functions in trans and proposes an experimental approach to dissect lncRNAs activity based on these classifications.

Integrated Genomic Characterization of Papillary Thyroid Carcinoma

Nishant Agrawal, +242 more
- 23 Oct 2014 - 
TL;DR: The genomic landscape of 496 PTCs is described and a reclassification of thyroid cancers into molecular subtypes that better reflect their underlying signaling and differentiation properties is proposed, which has the potential to improve their pathological classification and better inform the management of the disease.

Circular RNA profiling reveals an abundant circHIPK3 that regulates cell growth by sponging multiple miRNAs

TL;DR: The results provide evidence that circular RNA produced from precursor mRNA may have a regulatory role in human cells and characterize one abundant circRNA derived from Exon2 of the HIPK3 gene, termed circHIPK3.

Circular RNAs are a large class of animal RNAs with regulatory potency

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.

Natural RNA circles function as efficient microRNA sponges

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.

Circular RNAs are abundant, conserved, and associated with ALU repeats

TL;DR: High-throughput sequencing of libraries prepared from ribosome-depleted RNA with or without digestion with the RNA exonuclease showed that ecircRNAs are abundant, stable, conserved and nonrandom products of RNA splicing that could be involved in control of gene expression.
