Abstract: The formation of aggregates by polyglutamine-containing (polyQ) proteins in neurons is a key to the pathogenesis of several progressive neurodegenerative diseases such as Huntington's disease (HD) spinocerebellar ataxias (SCAs), and spinal and bulbar muscular atrophy… read more here.

DOI: 10.1016/j.redox.2020.101458
Abstract: Spinocerebellar ataxia type-1 (SCA1) is caused by an abnormally expanded polyglutamine (polyQ) tract in ataxin-1. These expansions are responsible for protein misfolding and self-assembly into intranuclear inclusion bodies (IIBs) that are somehow linked to neuronal… read more here.

DOI: 10.1038/s41388-020-1214-7
Abstract: Polyglutamine (polyQ) tract polymorphism within the human androgen receptor (AR) shows population heterogeneity. African American men possess short polyQ tracts significantly more frequently than Caucasian American men. The length of polyQ tracts is inversely correlated… read more here.

DOI: 10.1038/s41418-021-00914-9
Abstract: Huntington’s disease is caused by a pathologically long (>35) CAG repeat located in the first exon of the Huntingtin gene ( HTT ). While pathologically expanded CAG repeats are the focus of extensive investigations, non-pathogenic… read more here.

DOI: 10.1038/s41467-020-20000-x
Abstract: Cells adapt to conditions that compromise protein conformational stability by activating various stress response pathways, but the mechanisms used in sensing misfolded proteins remain unclear. Moreover, aggregates of disease proteins often fail to induce a… read more here.

DOI: 10.1111/andr.13339
Abstract: Ample evidence indicates a sex‐related difference in severity of COVID‐19, with less favorable outcomes observed in men. Genetic factors have been proposed as candidates to explain this difference. The polyglutamine (polyQ) polymorphism in the androgen… read more here.

DOI: 10.3389/fnmol.2017.00159
Abstract: Spinal and bulbar muscular atrophy (SBMA) is caused by expression of a polyglutamine (polyQ)-expanded androgen receptor (AR). The inefficient nuclear proteasomal degradation of the mutant AR results in the formation of nuclear inclusions containing amino-terminal… read more here.

DOI: 10.3390/genes11101129
Abstract: Background: Several experimental models of polyglutamine (polyQ) diseases have been previously developed that are useful for studying disease progression in the primarily affected central nervous system. However, there is a missing link between cellular and… read more here.

DOI: 10.3724/abbs.2023081
Abstract: Nine polyglutamine (polyQ) proteins have already been identified that are considered to be associated with the pathologies of neurodegenerative disorders called polyQ diseases, but whether these polyQ proteins mutually interact and synergize in proteinopathies remains… read more here.
