Fibroblast growth factor (FGF) 20 is a neurotrophic factor that exerts strong neurotrophic properties in the brain and could significantly enhance the survival of rat midbrain dopaminergic neurons. The genetic association of the FGF20 gene with Parkinson's disease (PD) remains controversial. We used the polymerase chain reaction-restriction length(More)
Increased nigral iron levels and intracytoplasmic Lewy bodies (LBs) in the degenerating neurons are found in Parkinson’s disease (PD). Whether LBs formation is involved in the toxicity of iron is largely unknown. In the present study, we observed that the toxicity of ferric iron was enhanced when SK-N-SH cells were overexpressed with wild-type(More)
The staging of Lewy-related pathology in sporadic Parkinson’s disease (PD) reveals that many brain nuclei are affected in PD during different stages, except the ventral tegmental area (VTA), which is close related to the substantia nigra (SN) and enriched in dopamine (DA) neurons. Why DA neurons are selectively degenerated in the SN of PD is far from known.(More)
Iron accumulation is considered to be involved in the pathogenesis of Parkinson’s disease (PD). Our previous studies have observed that Rg1, a major pharmacologically active ingredient from Ginseng, could protect dopaminergic neurons by reducing nigral iron levels through regulating the expression of iron transporters in(More)
Ginsenoside-Rg1 is one of the pharmacologically active components isolated from ginseng. It was reported that Rg1 protected dopamine (DA) neurons in 6-hydroxydopamine (6-OHDA)-induced Parkinson's disease (PD) models in vivo and in vitro. Our previous study also demonstrated that iron accumulation was involved in the toxicity of 6-OHDA. However, whether Rg1(More)
Ginsenoside-Rg1 is one of the pharmacologically active component isolated from ginseng. Our previous study observed the protective effect of Rg1 on iron accumulation in the substantia nigra (SN) in 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine (MPTP)-treated Parkinson's disease (PD) mice. However, the mechanisms of this neuroprotective effect of Rg1 are(More)
Iron plays a key role in Parkinson's disease (PD). Increased iron content of the substantia nigra (SN) has been found in PD patients, and divalent metal transporter 1 (DMT1) has been shown to be up-regulated in the SN of both MPTP-induced PD models and PD patients. However, the mechanisms underlying DMT1 up-regulation are largely unknown. In the present(More)
Ghrelin, a 28-amino acid peptide, is an endogenous ligand for the growth hormone secretagogue (GHS) receptor. Our previous data showed that ghrelin could inhibit apoptosis in Parkinson's disease (PD) models both in vitro and in vivo. There is now growing evidence that oxidative stress has a critical role in the etiology of PD. And ghrelin was reported to(More)
Persephin (PSPN) is one of the neurotrophic factors of the glial cell line-derived neurotrophic factor (GDNF) family ligands (GFLs) which have been found to promote the survival of specific populations of neurons. The aim of this study was to assess the potential therapeutic function of gene-modified mesenchymal stem cells (MSCs)-Lv-PSPN-MSCs in(More)
A novel integrated magnetic structure, which enables further reduction in an overall volume and weight of main inductors, the losses of the inductor windings and the channels by integrating the inductors in a single core, is proposed, for the telecom power application, and the operations and practical design considerations of the DC/DC boost converters(More)
