Nonsense-Mediated mRNA Decay, a Finely Regulated Mechanism

open access: yesBiomedicines, 2022
Nonsense-mediated mRNA decay (NMD) is both a mechanism for rapidly eliminating mRNAs carrying a premature termination codon and a pathway that regulates many genes.

Nonsense-mediated mRNA decay: friend or foe in cancer biology? [PDF]

open access: yesCell Communication and Signaling
Nonsense-mediated mRNA decay (NMD) is a highly conserved RNA surveillance mechanism in eukaryotic cells. It plays a key role in safeguarding the accuracy of gene expression by eliminating mRNAs with premature termination codons (PTCs) in the cellular ...

Identifying Potent Nonsense-Mediated mRNA Decay Inhibitors with a Novel Screening System [PDF]

open access: yesBiomedicines, 2023
Nonsense-mediated mRNA decay (NMD) is a quality control mechanism that degrades mRNAs carrying a premature termination codon. Its inhibition, alone or in combination with other approaches, could be exploited to develop therapies for genetic diseases ...

Nonsense-mediated mRNA decay: a key regulatory system engaged in cancer [PDF]

open access: yesCell Communication and Signaling
Nonsense-mediated mRNA decay (NMD) is a critical cellular surveillance mechanism that prevents the translation of defective or deleterious proteins. The regulation of NMD, including both its activation and the evasion of its target mRNA, is intricately ...

Reduced UPF1 levels in senescence impair nonsense-mediated mRNA decay [PDF]

open access: yesCommunications Biology
Cells regulate gene expression through various RNA regulatory mechanisms, and this regulation often becomes less efficient with age, contributing to accelerated aging and various age-related diseases.

Human disease-causing mutations result in loss of leiomodin 2 through nonsense-mediated mRNA decay. [PDF]

open access: yesPLoS Genetics
The leiomodin (Lmod) family of actin-binding proteins play a critical role in muscle function, highlighted by the fact that mutations in all three family members (LMOD1-3) result in human myopathies.

Cryo-EM reconstructions of inhibitor-bound SMG1 kinase reveal an autoinhibitory state dependent on SMG8

open access: yeseLife, 2021
The PI3K-related kinase (PIKK) SMG1 monitors the progression of metazoan nonsense-mediated mRNA decay (NMD) by phosphorylating the RNA helicase UPF1. Previous work has shown that the activity of SMG1 is impaired by small molecule inhibitors, is reduced ...

Unraveling the influences of sequence and position on yeast uORF activity using massively parallel reporter systems and machine learning

open access: yeseLife, 2023
Upstream open-reading frames (uORFs) are potent cis-acting regulators of mRNA translation and nonsense-mediated decay (NMD). While both AUG- and non-AUG initiated uORFs are ubiquitous in ribosome profiling studies, few uORFs have been experimentally ...

Cellular variability of nonsense-mediated mRNA decay

open access: yesNature Communications, 2021
Here the author developed a single-cell reporter system to identify cell-to-cell variability of nonsense-mediated mRNA decay (NMD). This approach provides a sensitive tool to investigate cellular heterogeneity of NMD in various physiological conditions.

RNA binding proteins PTBP1 and HNRNPL regulate CFTR mRNA decay

open access: yesHeliyon, 2023
Background: CFTR nonsense alleles generate negligible CFTR protein due to the nonsense mutation: 1) triggering CFTR mRNA degradation by nonsense-mediated mRNA decay (NMD), and 2) terminating CFTR mRNA translation prematurely.
