Tetrahydroxystilbene Glucoside Produces Neuroprotection against 6-OHDA-Induced Dopamine Neurotoxicity

Figure 3

TSG protected DA neurons against 6-OHDA-induced neurotoxicity in vitro. 6-OHDA-induced DA neurotoxicity was quantified by TH-positive neuron counting through the immunocytochemical analysis. Representative images of immunostaining from three experiments were shown (a). Scale bar = 100 μm. TH protein expression was determined by western blotting analysis. The ratio of densitometry values of TH with β-actin was assessed and normalized to each respective control group (b). Results were expressed as a percentage of the control group and were the mean ± SEM from three independent experiments performed in triplicate. compared with the control groups; compared with 6-OHDA-treated group.
