Aggregates, a hallmark of most neurodegenerative diseases, may have different properties, and possibly different roles in neurodegeneration. We analysed ubiquitin-proteasome pathway functions during cytoplasmic aggregation in polyglutamine (polyQ) diseases, using a unique model of motor neuron disease, the SpinoBulbar Muscular Atrophy. The disease, which is(More)
Several types of motorneuron diseases are linked to neurotoxic mutant proteins. These acquire aberrant conformations (misfolding) that trigger deleterious downstream events responsible for neuronal dysfunction and degeneration. The pharmacological removal of misfolded proteins might thus be useful in these diseases. We utilized a peculiar motorneuronal(More)
The androgen receptor (AR), a ligand-activated transcription factor, has been found mutated in several human diseases. While some mutations reduce, others potentiate AR functions generating different endocrine dysfunctions. A peculiar AR mutation, the CAG-repeat expansion encoding the AR-polyglutamine (polyQ) tract, generates a neurotoxic(More)
The androgen receptor (AR) is a ligand-activated transcription factor which is responsible for the androgen responsiveness of target cells. Several types of mutations have been found in the AR and linked to endocrine dysfunctions. Surprisingly, the polymorphism involving the CAG triplet repeat expansion of the AR gene, coding for a polyglutamine (PolyGln)(More)
