AIMS DJ-1/park7 is a ubiquitously expressed multifunctional protein that plays essential roles in a variety of cells. However, its function in the vascular system has not been determined. We investigated the protective roles of DJ-1/park7 in vascular disorders, especially in neointimal hyperplasia. METHODS AND RESULTS DJ-1/park7 was strongly expressed in the neointimal layer, in which its oxi...
[Purpose] Strength-duration (SD) curves are used in electrical diagnosis by physiotherapists to confirm muscle degeneration. However, the usefulness of SD curves in comparing muscle degeneration in DJ-1 homozygous knockout (DJ-1(-/-)) and wild-type mice (DJ-1(+/+)) is not yet fully understood. The electrical properties of the gastrocnemius muscles of DJ-1(-/-) and DJ-1(+/+) mice were compared i...
The manifestations of Parkinson's disease are caused by reduced dopaminergic innervation of the striatum. Loss-of-function mutations in the DJ-1 gene cause early-onset familial parkinsonism. To investigate a possible role for DJ-1 in the dopaminergic system, we generated a mouse model bearing a germline disruption of DJ-1. Although DJ-1(-/-) mice had normal numbers of dopaminergic neurons in th...
Loss-of-function mutations in the PARK7/DJ-1 gene cause early onset autosomal-recessive Parkinson disease. DJ-1 has been implicated in protection of neurons from oxidative stress and in regulation of transcriptional activity. However, whether there is a relationship between the subcellular localization of DJ-1 and its function remains unknown. Therefore, we examined the subcellular localization...
BACKGROUND The development of oral squamous cell carcinoma (OSCC) is a multistep process that involves in both genetic alterations and epigenetic modifications. DJ-1, a negative regulator of tumor suppressor PTEN, functions as an oncogene in many types of cancers. However, its role in OSCC is poorly known. METHODS Immunohistochemical staining and Western blotting were performed to evaluate th...
Mutations in the DJ-1 gene cause early-onset autosomal recessive Parkinson's disease (PD), although the role of DJ-1 in the degeneration of dopaminergic neurons is unresolved. Here we show that the major interacting-proteins with DJ-1 in dopaminergic neuronal cells are the nuclear proteins p54nrb and pyrimidine tract-binding protein-associated splicing factor (PSF), two multifunctional regulato...
Usage of ureteral DJ stent is very common in urology practise. There are some complications according to the increased usage of ureteral DJ stent in the literature. Stent fragmentation is a rare complication of ureteral DJ stent. In this study we present a 53-year-old male patient who had previous stone surgery and a ureteral DJ stent applied to our polyclinic with complaint of 3-months-long ri...
DJ-1, a Parkinson's disease (PD)-associated gene, has been shown to protect against oxidative stress in Drosophila. However, the molecular mechanism underlying oxidative stress-induced phenotypes, including apoptosis, locomotive defects, and lethality, in DJ-1-deficient flies is not fully understood. Here we showed that Daxx-like protein (DLP), a Drosophila homologue of the mammalian Death doma...
The oncogene DJ-1 has been associated with multiple cancers, including prostate cancer, where it can be stabilized by androgens and antiandrogens. However, little data exist on the expression pattern and function of DJ-1 in prostate cancer. To address the function of DJ-1 in prostate, a yeast two-hybrid screen was done to identify novel DJ-1 binding proteins. The androgen receptor (AR) was iden...
DJ-1 was identified by us as a novel oncogene that transforms mouse NIH3T3 cells in cooperation with ras. We later identified PIAS (protein inhibitor of activated STAT)xalpha as a DJ-1-binding protein, and found that DJ-1 restored androgen receptor (AR) transcription activity that was repressed by PIASxalpha. To further characterize the function of DJ-1, we cloned cDNA encoding a novel DJ-1-bin...
