Cancer cell invasion and unlimited proliferation are key factors in patients with colorectal cancer (CRC). Increased protein deglycase DJ-1 in cancer cells is known to promote tumor growth; however, its role in CRC progression is not well defined. In this study, we investigated 100 CRC patients with disease stages I-IV to determine whether DJ-1 could serve as a prognostic biomarker in CRC. Thes...

Mutations of the DJ-1 (PARK7) gene are linked to familial Parkinson's disease. We used gene targeting to generate DJ-1-deficient mice that were viable, fertile, and showed no gross anatomical or neuronal abnormalities. Dopaminergic neuron numbers in the substantia nigra and fiber densities and dopamine levels in the striatum were normal. However, DJ-1-/- mice showed hypolocomotion when subjecte...

Parkinson's disease (PD) is a common neurodegenerative disorder that displays both sporadic and inherited forms. Exposure to several common environmental toxins acting through oxidative stress has been shown to be associated with PD. One recently identified inherited PD gene, DJ-1, may have a role in protection from oxidative stress, thus potentially linking a genetic cause with critical enviro...

AIMS DJ-1 is a key redox-reactive neuroprotective protein implicated in regulation of oxidative stress after stroke. However, the molecular mechanism, especially the role of mitochondrial function, by which DJ-1 protects neural cells in stroke remains to be elucidated. The aim of this study was to reveal whether DJ-1 translocates into the mitochondria in exerting neuroprotection against oxidati...

Parkinson's disease (PD) is a progressive neurodegenerative disorder. Although the precise mechanism remains unclear, mounting evidence suggests that oxidative stress plays an important role in the pathogenesis of PD. DJ-1 gene is associated with oxidative stress and mutations in DJ-1 are involved in an autosomal recessive, early onset familial form of PD. The ERK1/2 signaling pathway contribut...

The identification of rare monogenic forms of Parkinson's disease (PD) has provided tremendous insight into the molecular pathogenesis of this disorder. Heritable mutations in alpha-synuclein, parkin, DJ-1 and PINK1 cause familial forms of PD. In the more common sporadic form of PD, oxidative stress and derangements in mitochondrial complex-I function are considered to play a prominent role in ...

The molecular mechanisms leading to neurodegeneration in Parkinson disease (PD) remain elusive, although many lines of evidence have indicated that -synuclein and DJ-1, two critical proteins in PD pathogenesis, interact with each other functionally. The investigation on whether -synuclein directly interacts with DJ-1 has been controversial. In the current study, we analyzed proteins associated ...

Two mutations in the DJ-1 gene on chromosome1p36 have been identified recently to cause early-onset, autosomal recessive Parkinson's disease. As no information is available regarding the distribution of DJ-1 protein in the human brain, in this study we used a monoclonal antibody for DJ-1 to map its distribution in frontal cortex and substantia nigra, regions invariably involved in Parkinson's d...

Loss of pancreatic β-cells by oxidative stress or cytokines is associated with diabetes mellitus (DM). DJ-1 is known to as a multifunctional protein, which plays an important role in cell survival. We prepared cell permeable wild type (WT) and mutant type (M26I) Tat-DJ-1 proteins to investigate the effects of DJ-1 against combined cytokines (IL-1β, IFN-γ and TNF-α)-induced RINm5F cell death. Bo...
