Towards a molecular understanding of microRNA-mediated gene silencing

TL;DR: Understanding of the mechanisms of silencing is enhanced, making it possible to describe in molecular terms a continuum of direct interactions from miRNA target recognition to mRNA deadenylation, decapping and 5′-to-3′ degradation.
Journal ArticleDOI

The complexity of miRNA-mediated repression.

TL;DR: The most recent advances in the understanding of the molecular underpinnings of miRNA-mediated repression are discussed and the multitude of regulatory mechanisms that modulate miRNA function are highlighted.

Stress granules, P-bodies and cancer

TL;DR: Evidence implicating RNA granules in the pathogenesis of cancer and their potential as targets for anticancer therapies are examined.

The Ccr4‐Not complex is a key regulator of eukaryotic gene expression

TL;DR: Ccr4‐Not is a master regulator of eukaryotic gene expression and is a key player in mRNA decay, generic mRNA decay that follows normal translation termination, co‐translational mRNA decay of transcripts on which the ribosomes stall durably or which carry a non‐sense mutation and finally mRNA Decay that is induced by external signaling for a change in genetic programming.

A DDX6-CNOT1 complex and W-binding pockets in CNOT9 reveal direct links between miRNA target recognition and silencing.

TL;DR: The structural basis for the repressive activity of CCR4-NOT and its interaction with TNRC6/GW182s is elucidated, and the crystal structure of this complex demonstrates striking similarity to the eIF4G-eIF4A complex.

MicroRNAs direct rapid deadenylation of mRNA.

TL;DR: It is shown that in mammalian cells this reduction in message abundance is a consequence of accelerated deadenylation, which leads to rapid mRNA decay, suggesting that miRNAs use two distinct posttranscriptional mechanisms to down-regulate gene expression.
Journal ArticleDOI

mRNA degradation by miRNAs and GW182 requires both CCR4:NOT deadenylase and DCP1:DCP2 decapping complexes

TL;DR: It is shown that depletion of GW182 leads to changes in mRNA expression profiles strikingly similar to those observed in cells depleted of the essential Drosophila miRNA effector AGO1, indicating that GW182 functions in the miRNA pathway.

The Many Pathways of RNA Degradation

TL;DR: From the earliest comparisons of RNA production with steady-state levels, it has been clear that cells transcribe more RNA than they accumulate, implying the existence of active RNA degradation systems.
Journal ArticleDOI

The enzymes and control of eukaryotic mRNA turnover.

TL;DR: It is highlighted that there are a variety of enzymes with different specificities, suggesting that individual nucleases act on distinct subpopulations of transcripts within the cell and multiple mechanisms by which mRNA degradation could be regulated.
