It provides a solid experimental basis for the development of drugs

5、for prevention and treatment of amyotrophic lateral sclerosis syndrome.Methods: CCK-8 Colorimetric Method were used to detect the effects of H2O2 and Curcumin-treated Cell on cell viability. Spectrophotometer were used to detect the changes of MDA and GSH in hSOD1G93A mutant transfected NSC-34 cells

6、 (SOD1G93A NSC-34) treated with H2O2 after pre-treated with curcumin. And the changes of GST and GCLC in the cells were detected by real-time PCR. Results: CCK-8 results were compared with different concentrations of H2O2 and curcumin on the cell viability, we selected the final concentration of 10

7、M H2O2 and 10 M curcumin as a follow-up study conditions. Compared with the transfected hSOD1 G93A mutant NSC-34 cells treated with H2O2 (10 M), spectrophotometry showed that the content of MDA in the cells pretreated with curcumin (10 M) was significantly decreased and the oxidative stress was sign

8、ificantly improved. After incubation with H2O2 for 24 h, the concentration of GSH in the cells was significantly decreased, and the concentration of GSH was increased by co-incubation with curcumin (10 M). In addition, real-time PCR results showed that the expression of GST and GCLC mRNA was increas

9、ed by curcumin pretreatment (P 0.01).Conclusion: Curcumin may enhance the ability of anti-oxidative stress in ALS cell models by enhancing the regulation of cell antioxidant production.Key words: Curcumin; Amyotrophic lateral sclerosis; Oxidative stress; MDA; GSH3前 言0 0 0 0 0 0 化 0 (Amyotrophic late
