Objective:
To investigate the protective effect of polysaccharides from sea cucumber (HS) on Glu-induced neurotoxicity in PC12 cells.
Methods:
The toxicity model was established by treating PC12 cells with Glu in vitro. Cell viability was assayed with MTT method. The vitality of antioxidant enzymes (SOD) and the level of malondialdehyde (MDA) and lactic dehydrogenase (LDH) were evaluated by chromatometry.
Results:
The vitality of SOD increased and the levels of MDA and LDH significantly decreased in PC12 cells of HS group compared with the model group. HS in different concentration showed protective effects as it increased the vitality of SOD and decreased the content of MDA and LDH in a dose-dependent manner.
Conclusion:
Polysaccharide from sea cucumber can protect PC12 cells from the injury induced by Glu.
