Parkinson's disease (PD) is a complex disease, with genetics and environment contributing to the disease onset. Recent studies of causative PD genes have confirmed the involvement of cellular mechanisms engaged in mitochondrial and UPS dysfunction, oxidative stress and apoptosis in the progressive degeneration of the dopaminergic neurons in PD. In addition,(More)
Glutathione peroxidase is an antioxidant enzyme that is involved in the control of cellular oxidative state. Recently, unregulated oxidative state has been implicated as detrimental to neural cell viability and involved in both acute and chronic neurodegeneration. In this study we have addressed the importance of a functional glutathione peroxidase in a(More)
Parkin Co-Regulated Gene (PACRG) is a novel gene that is oriented in a head-to-head array with parkin, and expression of the two genes is regulated by a shared bi-directional promoter. Mutations in parkin are the most common cause of early-onset autosomal recessive Parkinson's disease, however the function of PACRG and potential role in the pathogenesis of(More)
Alzheimer's disease (AD) is a progressive neurodegenerative disease and the most common cause of dementia. Deposition of amyloid-β (Aβ) remains a hallmark feature of the disease, yet the precise mechanism(s) by which this peptide induces neurotoxicity remain unknown. Neuroinflammation has long been implicated in AD pathology, yet its contribution to disease(More)
The functional organization of Gbetagamma is poorly understood. Regions of bovine brain Gbetagamma that interact with a photoaffinity derivative of an alpha2-adrenergic receptor-derived peptide from the third intracellular loop (diazopyruvoyl-modified peptide Q (DAP-Q)) and a hydrophobic membrane probe (3-trifluoromethyl-3-(m-iodophenyl)diazirine (TID))(More)
Mutations in parkin are a common cause of early-onset autosomal recessive Parkinson's disease. Parkin Co-Regulated Gene (PACRG) is a novel gene that was discovered because of its close genetic proximity to parkin and the two genes were subsequently demonstrated to be regulated by a bi-directional promoter. However the role of PACRG has not been well(More)
A neuro-inflammatory response has been implicated in human patients and animal models of Alzheimer's disease (AD). Type-1 interferons are pleiotropic cytokines involved in the initiation and regulation of the pro-inflammatory response; however, their role in AD is unknown. This study investigated the contribution of type-1 IFN signaling in the(More)
We have previously identified an increased susceptibility of glutathione peroxidase-1 (Gpx1)-/- mice to neuronal apoptosis following mid-cerebral artery (MCA) occlusion. This study was designed to elucidate the mechanisms involved in elevated neuronal cell death arising from an altered endogenous oxidant state. This was addressed in both an in vitro and in(More)
Rat liver albumin messenger RNA has been purified to apparent homogeneity by means of polysome immunoprecipitation and poly(U)-Sepharose affinity chromatography. Specific polysomes synthesizing albumin were separated from total liver polysomes through a double antibody technique which allowed isolation of a specific immunoprecipitate. The albumin-polysome(More)
Neuro-inflammation has long been implicated as a contributor to the progression of Alzheimer’s disease in both humans and animal models. Type-1 interferons (IFNs) are pleiotropic cytokines critical in mediating the innate immune pro-inflammatory response. The production of type-1 IFNs following pathogen detection is, in part, through the activation of the(More)
