A clinically-related animal model of Parkinson's disease (PD) may enable the elucidation of the etiology of the disease and assist the development of medications. However, none of the current neurotoxin-based models recapitulates the main clinical features of the disease or the pathological hallmarks, such as dopamine (DA) neuron specificity of degeneration(More)
Mutations of the glucocerebrosidase (GBA) gene have reportedly been associated with Parkinson disease (PD) in various ethnic populations such as Singaporean, Japanese, Formosan, Canadian, American, Portuguese, Greek, Brazilian, British, Italian, Ashkenazi Jewish, southern and southwestern Chinese. The purpose of this study is to determine in central China(More)
3-methyl-1-phenyl-2-pyrazolin-5-one (edaravone), an effective free radical scavenger, provides neuroprotection in stroke models and patients. In this study, we investigated its neuroprotective effects in a chronic rotenone rat model for Parkinson's disease. Here we showed that a five-week treatment with edaravone abolished rotenone's activity to induce(More)
Synaptic loss in the brain correlates well with disease severity in Alzheimer disease (AD). Deficits in brain-derived neurotrophic factor/tropomyosin-receptor-kinase B (TrkB) signaling contribute to the synaptic dysfunction of AD. We have recently identified 7,8-dihydroxyflavone (7,8-DHF) as a potent TrkB agonist that displays therapeutic efficacy toward(More)
Neurofibrillary tangles (NFTs), composed of truncated and hyperphosphorylated tau, are a common feature of numerous aging-related neurodegenerative diseases, including Alzheimer's disease (AD). However, the molecular mechanisms mediating tau truncation and aggregation during aging remain elusive. Here we show that asparagine endopeptidase (AEP), a lysosomal(More)
Autophagy-mediated self-digestion of cytoplasmic inclusions may be protective against neurodegenerative diseases such as Parkinson’s disease (PD). However, excessive autophagic activation evokes autophagic programmed cell death. In this study, we aimed at exploring the role of autophagy in the pathogenesis of rotenone-induced cellular and animal models for(More)
Neuronal cell cycle reentry maintained in a G2-like state before cell death, has been confirmed in dopaminergic neurons of patients with Parkinson's disease (PD). Caspase-3 is a final effector in apoptotic dopaminergic neurons in patients. The association of aberrant G2/M regulation with caspase-3 dependent apoptosis remains to be elucidated. Cell division(More)

BACKGROUND Idiopathic Parkinson disease (PD) is a common neurodegenerative disease that seriously hinders limb activities and affects patients' lives. We performed a meta-analysis aiming to systematically review and quantitatively synthesize the efficacy and safety of traditional Chinese medicine (TCM) as an adjunct therapy for clinical PD patients.

AIM To investigate the neuroprotective effects of morin on 1-methyl-4-phenylpyridinium ion (MPP(+))-induced apoptosis in neuronal differentiated PC12 cells as well as in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of Parkinson disease (PD). METHODS PC12 cells were challenged with MPP(+) in the presence or absence of morin. Cell(More)
