Regulation of DJ1 is associated with a number of human diseases. To determine the involvement of DJ1 in progression of diabetes in a gender-dependent manner, we investigated its tissue-specific expression in streptozotocin (STZ)-induced diabetic male and female rats in this study. In animal experiments, females showed greater susceptibility towards developing diabetes because of lower insulin s...

BACKGROUND HIV-associated neurological disorder (HAND) has long been recognized as a consequence of human immunodeficiency virus (HIV) infection in the brain. The pathology of HAND gets more complicated with the recreational drug use such as cocaine. Recent studies have suggested multiple genetic influences involved in the pathology of addiction and HAND but only a fraction of the entire geneti...

Carbendazim (methyl 1H-benzimidazol-2-yl carbamate) is one of the most widely used fungicides in agriculture worldwide, but has been reported to have adverse effects on animal health and ecosystem function. A highly efficient carbendazim-degrading bacterium (strain dj1-11) was isolated from carbendazim-contaminated soil samples via enrichment culture. Strain dj1-11 was identified as Rhodococcus...

DnaJ homologues function in cooperation with hsp70 family members in various cellular processes including intracellular protein trafficking and folding. Three human DnaJ homologues present in the cytosol have been identified: dj1 (hsp40/hdj-1), dj2 (HSDJ/hdj-2), and neuronal tissue-specific hsj1. dj1 is thought to be engaged in folding of nascent polypeptides, whereas functions of the other Dna...

Despite ubiquitous expression and a high level of metastasis-associated protein 1 (MTA1) coregulator, the physiological role of the MTA1 coactivator remains unknown. We found that MTA1 is a bona fide coactivator and stimulator of tyrosine hydroxylase (TH) transcription in neuronal cells and that MTA1-null mice had lower TH expression in the striatum and substantial nigra. MTA1 physically achiev...

We analyzed the DJ1 gene in a large consecutive series (N=163) of Italian unrelated Early Onset Parkinson Disease (EOPD: onset ≤40 years of age) patients and 100 healthy controls (mean age 64 ± 7 years). No homozygous or compound heterozygous mutations with an obvious pathogenic effect were found. Several variants were identified, some of which were novels. All variants had similar frequency in...

This study evaluated associations of heat shock proteins (HSP) and an oxidative stress protein, protein deglycase (DJ1), with beef quality tenderness. Samples from the longissimus thoracis (N = 99) were collected pre-rigor (day 0) after 14-d aging. Warner-Bratzler shear force (WBSF), myofibrillar fragmentation index (MFI), a trained sensory panel used to determine meat quality. Protein abundanc...
