The effect of Spirulina Microalgae extract on Bcl-2 Anti-Apoptotic Gene Expression in Brain Cancer Cell Line

Abstract

: U87 cell line contains glioblastoma cancer cells as the most acute type of human brain tumor. Increased expression of Bcl-2 gene in cancer cells has anti-apoptotic effect. In the present study the effect of Spirulina extract on gene expression in cancer cell line was investigated. In this cell The brain cancer cell line was procured and cultivated Iranian Biological Cells were divided into two treatment and control groups. Spirulina alga extract was affected on the treatment group and its toxicity was measured using MTT assay (compound 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromidefor). The reference gene in this study was GAPDH. RNA was extracted from control and control cells and cDNA was made. The expression of genes was evaluated using ∆∆Ct in Real-time PCR. The result of MTT assay showed that the IC50 (Median Inhibition Concentration) value was 10.01 mg/ml for the 48 hour treatment. The result of Real-time PCR showed that the expression of Bcl-2 and the anti-apoptotic gene significantly decreased 3 folds in treatment group. Conclusion: According to the results of MTT assay and Real-time PCR, the expression of Bcl-2 significantly decreased 3 times in treatment group.
