It is shown that DJ-1 mutations are associated with PARK7, a monogenic form of human parkinsonism, and these findings indicate that loss ofDJ-1 function leads to neurodegeneration.
Abstract
The DJ-1 gene encodes a ubiquitous, highly conserved protein. Here, we show that DJ-1 mutations are associated with PARK7, a monogenic form of human parkinsonism. The function of the DJ-1 protein remains unknown, but evidence suggests its involvement in the oxidative stress response. Our findings indicate that loss of DJ-1 function leads to neurodegeneration. Elucidating the physiological role of DJ-1 protein may promote understanding of the mechanisms of brain neuronal maintenance and pathogenesis of Parkinson's disease.

Reduced basal autophagy and impaired mitochondrial dynamics due to loss of Parkinson's disease-associated protein DJ-1.

TL;DR: It is shown that loss of DJ-1 leads to impaired autophagy and accumulation of dysfunctional mitochondria that under physiological conditions would be compensated via lysosomal clearance, providing evidence for a critical role ofDJ-1 in mitochondrial homeostasis in Parkinson's disease.

Gene expression profiling of parkinsonian substantia nigra pars compacta; alterations in ubiquitin-proteasome, heat shock protein, iron and oxidative stress regulated proteins, cell adhesion/cellular matrix and vesicle trafficking genes

TL;DR: One major finding is the particular decreased expression of SKP1A, a member of the SCF (E3) ligase complex specifically in the substantia nigra (SN) of sporadic parkinsonian patients, which may lead to a wide impairment in the function of an entire repertoire of proteins subjected to regulatory ubiquitination.

The Role of Environmental Exposures in Neurodegeneration and Neurodegenerative Diseases

TL;DR: The role of neurotoxicant exposures in neurodegenerative disease has long been suspected, with much effort devoted to identifying causative agents, but causative factors for a significant number of cases have yet to be identified.

WHAT IF: A molecular modeling and drug design program

TL;DR: The menu-driven operation of WHAT IF, combined with the use of default values wherever user input is required, makes it very easy to use for a novice user while keeping full flexibility for more sophisticated studies.

Twilight zone of protein sequence alignments.

TL;DR: All findings are applicable to automatic database searches and using intermediate sequences for finding links between more distant families was almost as successful: pairs were predicted to be homologous when the respective sequence families had proteins in common.

Increasing the precision of comparative models with YASARA NOVA--a self-parameterizing force field.

TL;DR: An all‐atom force field aimed at protein and nucleotide optimization in vacuo (NOVA), which has been specifically designed to avoid this problem and can be applied to modeling applications as well as X‐ray and NMR structure refinement.

DJ-1, a novel oncogene which transforms mouse NIH3T3 cells in cooperation with ras.

TL;DR: DJ-1 showed a cooperative transforming activity with H-Ras, more than 3 times as strong as the activity of ras/myc combination and is suggested to be a novel mitogen-dependent oncogene product involved in a Ras-related signal transduction pathway.
