Methylmercury can induce Parkinson's-like neurotoxicity similar to 1-methyl-4- phenylpyridinium: a genomic and proteomic analysis on MN9D dopaminergic neuron cells.
Low doses of paraquat and polyphenols prolong life span and locomotor activity in knock-down parkin Drosophila melanogaster exposed to oxidative stress stimuli: implication in autosomal recessive juvenile parkinsonism.
The behavioural and neuropathological impact of intranigral AAV-α-synuclein is exacerbated by systemic infusion of the Parkinson's disease-associated pesticide, rotenone, in rats.
α-Synuclein transgenic mice reveal compensatory increases in Parkinson's disease-associated proteins DJ-1 and parkin and have enhanced α-synuclein and PINK1 levels after rotenone treatment.
In addition, the co-expression of Cu/Zn superoxid dismutase protects against the dopaminergic neuronal loss induced by mutant alpha-synuclein overexpression thus identifying oxidative stress as an important causative factor in the pathology of autosomal-dominant Parkinsonism.
We screened 50 probands of families with autosomal dominant parkinsonism for alpha-synuclein mutations by exon sequencing.No known or novel mutations were found.
In the same year, from the identification of mutation in the alpha-synuclein gene in rare pedigrees with autosomal dominant parkinsonism, arose the concept that Parkinson's disease may be part of a broader group of 'synucleinopathies', in which there is a fundamental defect in protein processing.
The co-localization of NACP/alpha-synuclein and tau epitopes was examined in the brain stem and hippocampal formation in two patients from a family of autosomal dominant parkinsonism and dementia with Lewy bodies (LBs) without two reported missense mutations in the NACP gene.
A specific mutation (A53T) in the encoding region for alpha-synuclein has been identified in a large multigenerational family with an autosomal dominant parkinsonism known as the Contursi kindred.
