ALTERED EXPRESSION AND FUNCTIONALITY OF A2A ADENOSINE RECEPTORS IN HUNTINGTON’S DISEASE AND OTHER POLYGLUTAMINE DISORDERS [PDF]

open access: yes, 2009
Several studies have suggested the possible involvement of A2A adenosine receptors in the pathogenesis of neuronal disorders, including Huntington’s disease.

Polyglutamine (PolyQ) Diseases: Navigating the Landscape of Neurodegeneration [PDF]

open access: yes
Polyglutamine (polyQ) diseases are a group of inherited neurodegenerative disorders caused by expanded cytosine-adenine-guanine (CAG) repeats encoding proteins with abnormally expanded polyglutamine tract.

Expanded ATXN3 CAG Repeat is Stable in Human Purkinje Cells

open access: yesMovement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a neurodegenerative disorder caused by an abnormally long polyglutamine‐encoding CAG repeat in the ATXN3 gene. Objectives We aimed to determine whether somatic expansion of the mutant ATXN3 (mATXN3) CAG repeat is present in the output cell of the cerebellar cortex, the Purkinje cell (PC), in ...

miR-1 coordinately regulates lysosomal v-ATPase and biogenesis to impact proteotoxicity and muscle function during aging

open access: yeseLife, 2021
Muscle function relies on the precise architecture of dynamic contractile elements, which must be fine-tuned to maintain motility throughout life. Muscle is also plastic, and remodeled in response to stress, growth, neural and metabolic inputs.

ATXN8OS Intermediate Expansion Acts as a Genetic Modifier in Spinocerebellar Ataxia Type 48 (SCA48/STUB1)

open access: yesMovement Disorders, EarlyView.
Abstract Background Association between monoallelic STUB1 variant and expanded ATXN8OS alleles was recently reported, suggesting a pathogenic interaction that may influence spinocerebellar ataxia type 48 (SCA48) phenotype. Objectives We investigated the frequency and clinical impact of ATXN8OS in a large cohort of STUB1 carriers compared to individuals

Model of polyglutamine induced toxicity.

open access: yes, 2013
Activation p38MAPK signaling is counteracted by PKCι-mediated ERK activation in expanded polyglutamine expressing cells. The pharmacological blockade of ERK with U0126 or by PKCι depletion sensitizes cells to polyglutamine-induced death through a ...

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

open access: yesAndrology, 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.

Innovative approaches to monitor mutant huntingtin and to facilitate its degradation in Huntington's disease models [PDF]

open access: yes, 2011
Huntington’s disease (HD) is a dominant genetic neurodegenerative disease caused by a mutation in the exon 1 of the huntingtin gene. The clinical symptoms, such as motor disturbances (chorea), cognitive decline and psychiatric impairments are usually ...

Salidroside Protects Caenorhabditis elegans Neurons from Polyglutamine-Mediated Toxicity by Reducing Oxidative Stress

open access: yesMolecules, 2014
Polyglutamine (polyQ) aggregation plays a pivotal role in the pathological process of Huntington’s disease and other polyQ disorders. Therefore, strategies aiming at restoring dysfunction and reducing stresses mediated by polyQ toxicity are of ...

Hunting for the cause: Evidence for prion-like mechanisms in Huntington’s disease

open access: yesFrontiers in Neuroscience, 2022
The hypothesis that pathogenic protein aggregates associated with neurodegenerative diseases spread from cell-to-cell in the brain in a manner akin to infectious prions has gained substantial momentum due to an explosion of research in the past 10–15 ...
