Regulation of mRNA translation by MID1: a common mechanism of expanded CAG repeat RNAs

Frontiers in Cellular Neuroscience, 2016
Expansion of CAG repeats, which code for the disease-causing polyglutamine protein, is a common feature in polyglutamine diseases. RNA-mediated mechanisms that contribute to neuropathology in polyglutamine diseases are important. RNA-toxicity describes a

Natural Genetic Variation in Yeast Reveals That NEDD4 Is a Conserved Modifier of Mutant Polyglutamine Aggregation

G3: Genes, Genomes, Genetics, 2018
A feature common to late onset proteinopathic disorders is an accumulation of toxic protein conformers and aggregates in affected tissues. In the search for potential drug targets, many studies used high-throughput screens to find genes that modify the ...

Early and Progressive Spinal Cord Atrophy in Spinocerebellar Ataxia Type 1

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 1 (SCA1) is a rare, autosomal dominant neurodegenerative disorder characterized by progressive cerebellar and brainstem degeneration. Previous studies have shown that spinal cord atrophy is also a key aspect of SCA1 neuropathology.

Implications of Poly(A) Tail Processing in Repeat Expansion Diseases

Cells, 2022
Repeat expansion diseases are a group of more than 40 disorders that affect mainly the nervous and/or muscular system and include myotonic dystrophies, Huntington’s disease, and fragile X syndrome.

Limited Clinical Impact of Androgen Receptor Repeat Length (CAG and GGC) in Klinefelter Syndrome: A Multivariable Analysis

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.

An Exploration of the Universe of Polyglutamine Structures.

PLoS Computational Biology, 2015
Deposits of misfolded proteins in the human brain are associated with the development of many neurodegenerative diseases. Recent studies show that these proteins have common traits even at the monomer level.

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

The FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Targeting several CAG expansion diseases by a single antisense oligonucleotide. [PDF]

PLoS ONE, 2011
To date there are 9 known diseases caused by an expanded polyglutamine repeat, with the most prevalent being Huntington's disease. Huntington's disease is a progressive autosomal dominant neurodegenerative disorder for which currently no therapy is ...

PML as a neuroprotective guardian: Leveraging nuclear protein quality control to mitigate neurotoxicity of an ALS‐associated NEK1 variant

The FEBS Journal, EarlyView.
Insoluble protein aggregates are a hallmark of neurodegenerative diseases like amyotrophic lateral sclerosis (ALS). The ubiquitin–proteasome system (UPS) serves as a neuroprotective quality control mechanism that clears aggregates. PML nuclear bodies (NBs) were proposed to serve as hubs for SUMO‐primed ubiquitylation and degradation of misfolded ...

Polyglutamine disease: from pathogenesis to therapy

South African Medical Journal, 2012
Polyglutamine diseases are inherited neurodegenerative conditions arising from expanded trinucleotide CAG repeats in the disease-causing gene, which are translated into polyglutamine tracts in the resultant protein. Although these diseases share a common type of mutation, emerging evidence suggests that pathogenesis is complex, involving disruption of ...
