Abstract:
Polyglutamine diseases include at least 9 neurodegenerative disorders: Huntington's disease (HD), dentatorubral pallidoluysian atrophy (DRPLA), spinobulbar muscular atrophy (SBMA), and spinocerebellar ataxia (SCA) type: 1-3, 6-7 and 17, each caused by a CAG-trinucleotide repeat expansion in a different gene. The poly-CAG sequence is translated into a polyglutamine stretch in the respective proteins. This review discusses mutual molecular features of polyglutamine diseases. The formation of intranuclear inclusions, recruitment of physiological polyglutamine proteins as well as a potential role of molecular chaperones, capsases, and inhibition of histone acetyltransferases-depended transcription in cellular pathogenesis are considered.
