In an attempt to clarify the protective effect of puerarin on toxin-insulted dopaminergic neuronal death, this present study was carried out by using a typical Parkinson's disease (PD) model - 1-methyl-4-phenylpyridinium iodide (MPP(+))-induced dopaminergic SH-SY5Y cellular model. Data are presented, which showed that puerarin up-regulated Akt(More)
Neurodegeneration is one of the primary etiologies in the onset of Parkinson's disease. In the quest for a new antiparkinsonism treatment the potential benefits of puerarin from the roots of Pueraria lobata have been recognized. Thus, we examined whether puerarin is capable to protect dopaminergic neurons of the substantia nigra against 6-hydroxydopamine(More)
Although anticancer effect of gambogic acid (GA) and its potential mechanisms were well documented in past decades, limited information is available on the anticancer effect of gambogenic acid (GNA), another major active component of Gamboge. Here we performed a study to determine whether GNA possesses anticancer effect and find its potential mechanisms.(More)
Although the etiology of PD remains unclear, increasing evidence has shown that oxidative stress plays an important role in its pathogenesis and that of other neurodegenerative disorders. The phenolic glucoside gastrodin, a main constituent of a Chinese herbal medicine Gastrodia elata (GE) Blume, has been known to display antioxidant activity. The present(More)
Puerarin, an active component of Pueraria montana var. lobata (Willd.) Sanjappa & Pradeep is well-known for its anti-oxidative and neuroprotective activities. Although anti-Parkinson's disease activity of puerarin was reported in both of in vivo and in vitro model, detailed mechanisms are not clarified. In this study, we addressed that puerarin attenuated(More)
Gambogenic acid, identified from Gamboge, is responsible for anti-tumor effects, and has been shown to be a potential molecule against human cancers. In this study, the molecular mechanism of gambogenic acid-induced apoptosis in HepG2 cells was investigated. Gambogenic acid significantly inhibited cell proliferation and induced apoptosis. Acridine(More)
Paeonol, an active component of Moutan Cortex, has been recognized as a potential neuroprotective drug. In the present study, an injury model based on glutamate-induced cell death of rat pheochromocytoma cells was used to investigate the neuroprotective potential of paeonol and its mechanism of action. Our findings showed that paeonol dose-dependently(More)
In the present study, Gambogenic acid exhibits potential anti-tumor activity in several cancer cell lines. However, Gambogenic acid-induced apoptosis mechanism is not well understood. Here, we report that Gambogenic acid was capable to induce CNE-1 cells apoptosis and caused mitochondrial and endoplasmic reticulum injury, analyzed via transmission electron(More)
It is well known that puerarin possesses protective activity on neurodegenerative diseases. However, the exact path way involved in the protective effect of puerarin on MPP+ -induced cell death is unclear. In this study, we focused on mitochondria im pairment in the apoptotic process of MPP+ -elicited SH-SY5Y cells and detected the protection of puerarin.(More)
