In the present study, we investigated the neuroprotective effects of kaempferol in the mouse model of Parkinson's disease, which was induced by neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). We confirmed that MPTP led to behavioral deficits, depletion of dopamine and its metabolites, reduction in superoxide dismutase (SOD) and glutathione(More)
Parkinson's disease (PD) is characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra (SN) with the presence of alpha-synuclein inclusions termed Lewy bodies. The aggregation of alpha-synuclein into oligomeric species affects neuronal viability, having a causal role in the development of PD. The neuroprotective effects of(More)
Parkinson's disease (PD) is a neurodegenerative disorder characterized by progressive loss of dopaminergic (DA) neurons at the substantia nigra. Mitochondrial dysfunction is involved in the mechanism of cell damage in Parkinson's disease (PD). 6-Hydroxydopamine (6-OHDA) is a dopamine analog which specifically damages dopaminergic neurons. Baicalein has been(More)
In recent studies, alterations in the activity and expression of metabolic enzymes, such as those involved in glycolysis, have been detected in morphine-dependent patients and animals. Increasing evidence demonstrates that the hippocampus is an important brain region associated with morphine dependence, but the molecular events occurring in the hippocampus(More)
Protocatechuic aldehyde (PAL) has been reported to bind to DJ-1, a key protein involved in Parkinson's disease (PD), and exerts potential neuroprotective effects via DJ-1 in SH-SY5Y cells. In this study, we investigated the neuroprotective pharmacological effects of PAL against neurotoxin-induced cell and animal models of PD. In cellular models of PD, PAL(More)
Parkinson disease (PD) is the second most common neurodegenerative disease, and it cannot be completely cured by current medications. In this study, DJ-1 protein was administrated into medial forebrain bundle of PD model rats those had been microinjected with 6-hydroxydopamine (6-OHDA) or MG-132. We found that DJ-1 protein could reduce apomorphine-induced(More)
Cannabinoid agonists impair hippocampus-dependent learning and memory. Using mouse hippocampal slice preparations, we examined the effect of anandamide, an endogenous cannabinoid, on sharp wave-ripple (SW-R) complexes, which are believed to mediate memory consolidation during slow-wave sleep or behavioral immobility. Anandamide reduced the frequency of(More)
Clinical proteomics is a powerful tool that can be used to identify proteins that are differentially expressed in disease states, leading to greater understanding of the molecular and cellular events that contribute to disease. The aim of this study was to identify protein changes in the sera from Chinese Parkinson's disease (PD) patients, with the goal of(More)
Parkinson's disease is characterized by the progressive degeneration of midbrain dopaminergic neurons. Buddleia lindleyana is a traditional Chinese herb, commonly called Zui Yu Cao. The purification and identification of pedicularioside A and other phenylethanoid glycosides from this plant have been reported. However, their neuroprotective effects on the(More)
The initial aim of this study was to identify protein changes in the dorsal root ganglia (DRG) associated with long-term morphine treatment. We carried out a differential proteomics analysis on samples from the DRG of control and morphine-dependent rats (5-40 mg/kg, subcutaneously, twice daily for 28 days) after 4 days of morphine withdrawal.
