Early studies showed that Rpn4 (also named Son1 and Ufd5) is a transcriptional activator of the Saccharomyces cerevisiae proteasome genes, and that Rpn4 is rapidly degraded by the 26S proteasome. These observations suggested that in vivo proteasome abundance may be …

WebBackground and aims Huntington’s Disease (HD) is a neurodegenerative condition caused by abnormal expansions (>37) of a polyglutamine (PolyQ) tract in the huntingtin protein (Htt). Dopamine (DA) induces oxidative stress and causes toxicity in neurons. DA may exacerbate neuronal loss in the striatum. Autophagy is a lysosomal degradation ... WebTransmissible spongiform encephalopathies (TSEs) are neurodegenerative pathologies characterized by the accumulation of amyloid fibrils mainly composed of the pathological isoform of the prion protein (PrP TSE).PrP TSE pre-amyloid fibrils are supposed to induce neurodegenerative lesions possibly through the alteration of membrane permeability. The …
