AIMS To investigate effects of DNA methyltransferase (DNMT) inhibitors on dopaminergic neurons and its underlied mechanism. METHODS The DNMT inhibitor 5-aza-2'-deoxycytidine (5-aza-dC) was tested in cultured dopaminergic cells. Cell viability and apoptosis were assayed with 5-aza-dC alone. Neurotoxicity of 1-methyl-4-phenylpyridinium (MPP(+) ),(More)
Currently, antidepressants are the dominative treatment for depression, but they have limitations in efficacy and may even produce troublesome side effects. Electroacupuncture (EA) has been reported to have therapeutic benefits in the treatment of depressive disorders. The present study was conducted to determine whether EA could enhance the antidepressant(More)
Parkinson's disease (PD) is an aging-associated neurodegenerative disorder with progressive pathology involving the loss of midbrain dopaminergic neurons. Neurotrophic factors are promising for PD gene therapy; they are integrally involved in the development of the nigrostriatal system. Cerebral dopamine neurotrophic factor (CDNF) was recently discovered to(More)
BACKGROUND AND AIMS Tenuigenin (Ten) is a Chinese herbal extract with antioxidative and antiinflammatory effects on toxin-induced cell models of Parkinson's disease (PD); however, its effects on α-synuclein toxicity-based PD models remain unknown. α-synuclein hyperphosphorylation is a key event in PD pathogenesis and potential target of therapeutic(More)
The complex pathogenesis of Alzheimer's disease (AD) involves multiple contributing factors, including amyloid β (Aβ) peptide accumulation, inflammation and oxidative stress. Effective therapeutic strategies for AD are still urgently needed. Triptolide is the major active compound extracted from Tripterygium wilfordii Hook.f., a traditional Chinese(More)
Electroacupuncture (EA), especially high-frequency EA, has frequently been used as an alternative therapy for Parkinson disease (PD) and is reportedly effective for alleviating motor symptoms in patients and PD models. However, the molecular mechanism underlying its effectiveness is not completely understood. To implement a full-scale search for the targets(More)
Microglia are key players for the inflammatory responses in the central nervous system. Suppression of microglial activation and the resulting production of proinflammatory molecules are considered a promising strategy to alleviate the progression of neurodegenerative disorders. Triptolide was demonstrated as a potent anti-inflammatory compound both in(More)
Oxidative stress and neuroinflammation are early events associated with dopaminergic neuronal degeneration in Parkinson's disease (PD). Previous studies indicated that electroacupuncture (EA) stimulation is effective in protecting dopaminergic neurons from degeneration in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD. In this(More)
The acupuncture or electroacupuncture (EA) shows the therapeutic effect on various neurodegenerative diseases. This effect was thought to be partially achieved by its ability to alleviate existing neuroinflammation and glial dysfunction. In this study, we systematically investigated the effect of EA on abnormal neurochemical changes and motor symptoms in a(More)
