| Abstract: | objective: In order to find out the mechanisms that macrophage colony-stimulating factor (M-CSF) exerted its functions in alleviating the tert-butyl hydroperoxide (tbOOH)-induced oxidative injury to monocytes/macrophages. Methods: M-CSF riched L929 cell conditioned, medium (L929-CM) was used as the source of M-CSF.The antioxidant system in RAW264.7 cells were investigated by applying biochemical analysis such as enzyme activity detection. Results: M-CSF was showed to improve catalase activity and the content of reduced glutathione, while decrease the content of lipoperoxide in RAW264. 7 cells. M-CSF-treated cells also maintained high antioxidant capability when tbOOH attacked. Conclusion: M-CSF could. alleviate the oxidative injury to RAW264 .7 cells through improving their redox status. |
