Abstract Title: 

Study the antioxidant effects of blue-green algae Spirulina extract on ROS and MDA production in human lung cancer cells.

Abstract: 

In order to study the effects of Spirulina,, two cell lines of A549 and HFF were treated with the concentration of IC50 for 24 h. MTT analysis showed that the highest decrease in viability of cells happened at the concentration of 500 μg/ml. The necrosis, releases of LDH, produced DCFH, and Lipid peroxidation were higher in the cancer cell lines in comparison to normal cells. Results showed that the extract affected thecell cycle of the A549 cell line. Also, the algal extract had concentration-dependent antioxidant activity. Also, the production of malonyl dialdehyde was significantly higher in treated cells and there was a significant relationship between produced MDA and ROS. Results showed thatextract had a remarkable effect on the lung cancer cell cycle and arrest the cell cycle in phase G; so the cells didn't enter phase M and the proliferation of cancer cells prevented. Furthermore, according to the higher production of ROS and MDA in treated A549 cancer cell lines, it could be concluded that this algal extract could be considered as a natural product with anticancer activity against lung cancer cells.
