Competitive effects in bacterial mRNA decay

open access: yesJournal of Theoretical Biology, 2020
In living organisms, the same enzyme catalyses the degradation of thousands of different mRNAs, but the possible influence of competing substrates has been largely ignored so far. We develop a simple mechanistic model of the coupled degradation of all cell mRNAs using the total quasi-steady-state approximation of the Michaelis-Menten framework ...

The 5'-3' exoribonuclease pacman is required for epithelial sheet sealing in Drosophila and genetically interacts with the phosphatase puckered [PDF]

open access: yes, 2008
Background information. Ribonucleases have been well studied in yeast and bacteria, but their biological significance to developmental processes in multicellular organisms is not well understood.

Nonsense-mediated mRNA decay in mammals [PDF]

open access: yesJournal of Cell Science, 2005
Nonsense-mediated mRNA decay (NMD) in mammalian cells generally degrades mRNAs that terminate translation more than 50-55 nucleotides upstream of a splicing-generated exon-exon junction (reviewed in [Maquat, 2004a][1]; [Nagy and Maquat, 1998][2]).

A Low Dimensional Approximation For Competence In Bacillus Subtilis

open access: yes, 2015
The behaviour of a high dimensional stochastic system described by a Chemical Master Equation (CME) depends on many parameters, rendering explicit simulation an inefficient method for exploring the properties of such models.

Investigating the mechanism behind the feedback regulation of the Exon Junction Complex component MAGOH [PDF]

open access: yes, 2020
RNA binding proteins are critical for regulation of RNA function, and therefore maintaining appropriate levels of these proteins is important for cellular regulation.

Identification of a novel human E-Cadherin splice variant andassessment of its effects upon EMT-related events [PDF]

open access: yes, 2018
Epithelial Cadherin (E-cadherin) is involved in calcium-dependent cell-cell adhesion and signal transduction. The E-cadherin decrease/loss is a hallmark of Epithelial to Mesenchymal Transition (EMT), a key event in tumor progression.

Mechanisms of endonuclease‐mediated mRNA decay [PDF]

open access: yesWIREs RNA, 2011
AbstractEndonuclease cleavage was one of the first identified mechanisms of mRNA decay but until recently it was thought to play a minor role to the better‐known processes of deadenylation, decapping, and exonuclease‐catalyzed decay. Most of the early examples of endonuclease decay came from studies of a particular mRNA whose turnover changed in ...

Robust filtering for stochastic genetic regulatory networks with time-varying delay [PDF]

open access: yes, 2009
This is the post print version of the article. The official published version can be obtained from the link - Copyright 2009 Elsevier LtdThis paper addresses the robust filtering problem for a class of linear genetic regulatory networks (GRNs) with ...

RNA decay during gammaherpesvirus infection reduces RNA polymerase II occupancy of host promoters but spares viral promoters.

open access: yesPLoS Pathogens, 2020
In mammalian cells, widespread acceleration of cytoplasmic mRNA degradation is linked to impaired RNA polymerase II (Pol II) transcription. This mRNA decay-induced transcriptional repression occurs during infection with gammaherpesviruses including ...

Suppressing nonsense--a surprising function for 5-azacytidine. [PDF]

open access: yes, 2014
In this issue of EMBO Molecular Medicine, Bhuvanagiri et al report on a chemical means to convert molecular junk into gold. They identify a chemical inhibitor of a quality control pathway that is best known for its ability to clear cells of rubbish, but ...
