Polyglutamine diseases are a collection of nine CAG trinucleotide expansion disorders, presenting with a spectrum of neurological and clinical phenotypes. Recent human, mouse and cell studies of Huntington's disease have highlighted the role of DNA repair genes in somatic expansion of the CAG repeat region, modifying disease pathogenesis.

Autophagy and polyglutamine diseases [PDF]
In polyglutamine diseases, an abnormally elongated polyglutamine tract results in protein misfolding and accumulation of intracellular aggregates. The length of the polyglutamine expansion correlates with the tendency of the mutant protein to aggregate, as well as with neuronal toxicity and earlier disease onset.

Are Polyglutamine Diseases Expanding? [PDF]
It remains a matter of speculation as to whether the sense CUG-containing RNA and/or the antisense CAG-encoding polyglutamine peptide serves as the pathogenic moiety in Huntington's disease like-2 (HDL2). In this issue of Neuron, Wilburn et al. show that in a HDL2 mouse model, the polyglutamine peptide drives disease progression.

Hosting Neurotoxicity in Polyglutamine Disease [PDF]
Polyglutamine diseases are caused by an expanded glutamine domain thought to confer a toxic activity onto the respective disease proteins. In this issue, propose that toxicity of the polyglutamine protein Ataxin-1 may not be due to abberant protein interactions mediated by the polyglutamine expansion.

Skeletal Muscle Pathogenesis in Polyglutamine Diseases [PDF]
Polyglutamine diseases are characterized by selective dysfunction and degeneration of specific types of neurons in the central nervous system. In addition, nonneuronal cells can also be affected as a consequence of primary degeneration or due to neuronal

Activation of p38MAPK contributes to expanded polyglutamine-induced cytotoxicity.
BackgroundThe signaling pathways that may modulate the pathogenesis of diseases induced by expanded polyglutamine proteins are not well understood.Methodologies/principal findingsHerein we demonstrate that expanded polyglutamine protein cytotoxicity is ...

An accurate model of polyglutamine
AbstractPolyglutamine repeats in proteins are highly correlated with amyloid formation and neurological disease. To better understand the molecular basis of glutamine repeat diseases, structural analysis of polyglutamine peptides as soluble monomers, oligomers, and insoluble amyloid fibrils is necessary.

Polyglutamine makes the switch
In worms, a regulator of noncoding RNA directly catalyzes formation of toxic protein aggregates in the presence of polyglutamine.

Altered Metabolic Signaling and Potential Therapies in Polyglutamine Diseases
Polyglutamine diseases comprise a cluster of genetic disorders involving neurodegeneration and movement disabilities. In polyglutamine diseases, the target proteins become aberrated due to polyglutamine repeat formation.

Polyglutamine Repeat Length-Dependent Proteolysis of Huntingtin [PDF]
Amino-terminal fragments of huntingtin, which contain the expanded polyglutamine repeat, have been proposed to contribute to the pathology of Huntington's disease (HD).
