Hyperphosphorylation amplifies UPF1 activity to resolve stalls in nonsense-mediated mRNA decay

Nature Communications, 2016
Gene expression is regulated by a range of mechanisms, including post-translational modifications such as phosphorylation. Here the authors present evidence for a feedback mechanism whereby hyperphosphorylation of UPF1 in response to delays in nonsense ...

The role of RNA helicases in aging and lifespan regulation

Translational Medicine of Aging, 2017
RNA helicases are members of a large family of enzymes that function in unwinding RNA duplexes and modulating interactions between RNAs and proteins. RNA helicases participate in numerous cellular processes, including transcription, translation, mRNA ...

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

CA9‐Targeted PET Imaging for Noninvasive Discrimination of Clear Cell Renal Cell Carcinoma and Associated Tumor Biological Features

Advanced Science, EarlyView.
CA9‐targeted PET imaging could be a noninvasive approach to characterize clear cell renal cell carcinoma and associated tumor biology. PET uptake correlates with tumor CA9 expression and is linked to angiogenic activity, immune remodeling, and metabolic reprogramming.

The Role of Stress Granules and the Nonsense-mediated mRNA Decay Pathway in Antiviral Defence [PDF]

, 2019
Eukaryotic cells have evolved a number of survival tactics and quality control pathways that are able to counter intrinsic error-prone mechanisms and allow for maintenance of cellular homeostasis in the face of external stresses. This review will discuss

COX14 Variants Are Associated With Mitochondrial Complex IV Deficiency Nuclear Type 10 (MC4DN10)

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT COX14 encodes a transmembrane protein essential for cytochrome c oxidase (COX) complex assembly. A homozygous missense variant in COX14 was reported in three siblings from a single consanguineous family with severe, fatal infantile mitochondrial complex IV deficiency nuclear type 10 (MC4DN10; MIM# 619053).

Beyond quality control: The role of nonsense-mediated mRNA decay (NMD) in regulating gene expression [PDF]

, 2018
Nonsense-mediated mRNA decay (NMD) has traditionally been described as a quality control system that rids cells of aberrant mRNAs with crippled protein coding potential.

Dual Aberrant Splicing Caused by an Apparently Missense CHD7 Variant, c.5273A>G (p.Asp1758Gly), in CHARGE Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT CHARGE syndrome is a rare congenital disorder primarily attributed to heterozygous pathogenic variants of the CHD7 gene. Most pathogenic CHD7 variants are loss‐of‐function (LoF) variants, whereas the interpretation of missense variants remains challenging in the absence of functional evidence for their pathogenicity.

Nonsense-mediated mRNA decay

, 2008
Translation and mRNA decay are coupled processes; the link is most obvious in the case of NMD (nonsense-mediated mRNA decay). NMD is a mechanism that drastically reduces the level of mRNA harbouring PTCs (premature translation termination codons).

Extending the ATP9A‐Related Phenotypic Spectrum: Indication of Schizophrenia Susceptibility

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT ATP9A, which belongs to the P4‐ATPase family of proteins, is involved in the efficient transport of vesicles from the Golgi apparatus to the plasma membrane, as well as the release of extracellular vesicles from human cells. In 2021, a loss‐of‐function variant of this gene was identified as being associated with a recessive neurodevelopmental ...
