Arabidopsis mRNA decay landscape arises from specialized RNA decay substrates, decapping-mediated feedback, and redundancy

RS Sorenson, MJ Deshotel… - Proceedings of the …, 2018 - National Acad Sciences
The decay of mRNA plays a vital role in modulating mRNA abundance, which, in turn,
influences cellular and organismal processes. In plants and metazoans, three distinct …

Transcription dynamics regulate poly (A) tails and expression of the RNA degradation machinery to balance mRNA levels

B Slobodin, A Bahat, U Sehrawat, S Becker-Herman… - Molecular cell, 2020 - cell.com
Gene expression is regulated by the rates of synthesis and degradation of mRNAs, but how
these processes are coordinated is poorly understood. Here, we show that reduced …

P Tesina, E Heckel, J Cheng… - Nature Structural & …, 2019 - nature.com
Messenger RNA (mRNA) homeostasis represents an essential part of gene expression, in
which the generation of mRNA by RNA polymerase is counter-balanced by its degradation …

XRN1 stalling in the 5'UTR of Hepatitis C virus and Bovine Viral Diarrhea virus is associated with dysregulated host mRNA stability

SL Moon, JG Blackinton, JR Anderson… - PLoS …, 2015 - journals.plos.org
We demonstrate that both Hepatitis C virus (HCV) and Bovine Viral Diarrhea virus (BVDV)
contain regions in their 5'UTRs that stall and repress the enzymatic activity of the cellular 5' …

Size-dependent modulation of graphene oxide–aptamer interactions for an amplified fluorescence-based detection of aflatoxin B 1 with a tunable dynamic range

JJ Zhang, Z Li, S Zhao, Y Lu - Analyst, 2016 - pubs.rsc.org
Aflatoxin B1 (AFB1) is a common toxin found in many foods. While AFB1 sensors have been
reported, few studies have shown amplified detection with tunable dynamic ranges. We …

B Blasco-Moreno, L de Campos-Mata… - Nature …, 2019 - nature.com
Abstract The highly conserved 5'–3'exonuclease Xrn1 regulates gene expression in
eukaryotes by coupling nuclear DNA transcription to cytosolic mRNA decay. By integrating …

Viral nucleases induce an mRNA degradation-transcription feedback loop in mammalian cells

E Abernathy, S Gilbertson, R Alla, B Glaunsinger - Cell host & microbe, 2015 - cell.com
Gamma-herpesviruses encode a cytoplasmic mRNA-targeting endonuclease, SOX, that
