PABPC1 in Cancer: From a Translational Housekeeper to a Stress‐Responsive Regulatory Hub

Cancer Science, EarlyView.
PABPC1 shifts from a translational housekeeper to a stress‐responsive oncogenic hub via phase separation, PTMs, and non‐coding RNA crosstalk, selectively driving oncogene translation and therapy resistance in cancer. ABSTRACT PABPC1, long recognized as a constitutive translational housekeeper, has emerged as a stress‐responsive translational ...

UPF1-like helicase grip on nucleic acids dictates processivity

Nature Communications, 2018
UPF1 is a highly processive helicase that plays an essential role in nonsense-mediated mRNA decay. Here the authors use single molecule binding assays to establish a functionally important relationship between helicase grip to nucleic acids, binding ...

Stop that nonsense!

eLife, 2014
Cells can avoid the effects of so-called ‘nonsense’ mutations by several methods, including a newly discovered mechanism driven by microRNA molecules.

Kcnv2 E151X Mouse Captures Hallmarks of KCNV2‐Associated Retinal Dystrophy

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background KCNV2‐associated retinopathy is a rare inherited retinal dystrophy caused by variants in the KCNV2 gene, leading to disrupted photoreceptor behaviour and progressive deterioration of vision. Patients have characteristic electroretinography abnormalities, including reduced cone response, delayed and reduced rod response to low light ...

Mechanistic aspects of mRNA targeting for nonsense-mediated mRNA decay in human cells

, 2013
The nonsense-mediated mRNA decay (NMD) pathway is best known as a translation-coupled quality control system that recognizes and degrades aberrant mRNAs with ORF-truncating premature termination codons (PTCs), but a more general role of NMD in ...

SMG6 mediated degradation of nonsense mRNA requires phosphorylation-independent interaction with the helicase domain of UPF1

, 2014
Eukaryotic mRNAs with premature translation-termination codons (PTCs) are recognized and eliminated by nonsense-mediated mRNA decay (NMD). NMD targeted mRNAs can be degraded by different routes that all involve phosphorylated UPF1 (P-UPF1) as a starting ...

Pathogenicity of NUSAP1 Variants Is Defined by NMD‐Escape: Evidence From Two Novel Cases and Systematic Population‐Based Variant Analysis

Clinical Genetics, EarlyView.
Heterozygous de novo nonsense variants in the penultimate and last exons of NUSAP1 were identified in two unrelated individuals, predicted to escape NMD. In population data, nonsense variants were observed in exons 1–9 (of 11) in NUSAP1 but were absent from its 3′‐terminal region.

Therapeutic Nonsense Suppression Modalities: From Small Molecules to Nucleic Acid-Based Approaches

Biomedicines
Nonsense mutations are genetic mutations that create premature termination codons (PTCs), leading to truncated, defective proteins in diseases such as cystic fibrosis, neurofibromatosis type 1, Dravet syndrome, Hurler syndrome, Beta thalassemia ...

Genetic Testing Unveils a Novel Thrombospondin‐1 Domain Containing Protein 1 Gene Variant as the Cause of Chronic Edema in a 79‐Year‐Old Woman

Clinical Genetics, EarlyView.
A 79‐year‐old woman with lifelong peripheral edema and an affected sister was found to harbor a novel homozygous THSD1 splice‐site variant. Reduced THSD1 expression in dermal endothelial cells supported the possibility that this variant contributes to chronic hereditary edema.
