Accumulation of misfolded proteins in the endoplasmic reticulum (ER) is the main event leading to the induction of the ER stress-related unfolded protein response (UPR). Recent postmortem evaluation, showing that the UPR pathway is activated in nigral dopaminergic neurons bearing α-synuclein inclusions in the brain of Parkinson's disease (PD) patients,(More)
Nerve growth factor (NGF) is well characterized for its neurotrophic actions on peripheral sensory and sympathetic neurons and on central cholinergic neurons of the basal forebrain. Recent evidence, however, has shown high levels of NGF to be present in a variety of biological fluids after inflammatory and autoimmune responses, suggesting that NGF is a(More)
Activation of the nuclear factor κB/c-Rel can increase neuronal resilience to pathological noxae by regulating the expression of pro-survival manganese superoxide dismutase (MnSOD, now known as SOD2) and Bcl-xL genes. We show here that c-Rel-deficient (c-rel(-/-)) mice developed a Parkinson's disease-like neuropathology with ageing. At 18 months of age,(More)
Activation of the nuclear factor jB/c-Rel can increase neuronal resilience to pathological noxae by regulating the expression of pro-survival manganese superoxide dismutase (MnSOD, now known as SOD2) and Bcl-xL genes. We show here that c-Rel-deficient (c-rel À / À) mice developed a Parkinson's disease-like neuropathology with ageing. At 18 months of age,(More)
Evidence indicate that it is difficult to obtain specific antibodies to G protein-coupled receptors and different technical difficulties may allow the generation of antibodies that lack specificity. We conducted experiments to validate the specificity of commercially available antibodies raised against dopamine (DA) receptors hD(1), hD(4), and hD(5) using a(More)
Mesolimbocortical dopamine plays a role in learning and memory. The specific receptor subtypes mediating the effects of dopamine, however, are still unknown. Dopamine D2, D3 and D4 receptors are expressed in the hippocampus and dopamine D3 receptors are present in the septal area, suggesting that these receptor subtypes can contribute to the behavioral(More)
AIM Several studies have proposed a role for alpha1 adrenoceptors (ARs) in ureteral physiology, indicating that they are present in the ureter; however, few studies have been done to identify alpha1 AR subtypes present in this area. Thus, this study was carried out to characterize the alpha1 AR subtype gene and protein expression in proximal, medial, and(More)
Non-metastatic glycoprotein melanoma protein B (GPNMB), also known as osteoactivin (OA) is expressed in a wide array of tumors and represents an emerging target for drug development. In this study, we investigated the role of GPNMB/OA in the progression of human metastatic DU145 and PC3 prostate cancer cells. GPNMB/OA contribution in PCa malignant phenotype(More)
GH-3 is an established cell line which, for the production of both PRL and GH, may be related to the bipotential somatomammotroph from which both somatotroph and mammotroph cells derive. In the present study we first report that GH-3 cells express both the gp140trk and the gp75 components of the nerve growth factor (NGF) receptor and that NGF dictates a(More)
The effects of L-alpha-glycerylphosphorylcholine (alpha-GPC) on scopolamine-induced memory impairment and on brain acetylcholine (ACh) synthesis and release were investigated in rats. Oral administration of alpha-GPC 3 h before the behavioural test prevented the learning impairment induced by scopolamine given 30 min before the acquisition of a passive(More)
