Resveratrol On The Inflammatory Environment Of Rat Bone Marrow Mesenchymal Cells

Our study assesses the mechanism of Sirt-1 signaling pathway and inflammation changes after spinal cord injury (SCI). SD rats were assigned into Sham group and SCI group. The Sham group only received bites off the corresponding vertebral lamina without the blow operation. The Western Blot method was used to detect Sirt-1 level, ELISA analyzed IL-1p and IL-6 level in the spinal cord tissues along with measuring Sirt-1 and TNF-alpha level by immunofluorescence staining. Sirt-1 changed with the time after SCI and was significantly higher than sham operation group at 1 day after injury, reaching the highest level at 3 days followed by a decrease. IL-1 beta and IL-6 after SCI was significantly higher than sham operation group at 1 day after injury. Immunofluorescence double staining showed that Sirt-1 and TNF-alpha expression in spinal cord tissue after injury were upregulated. The expression of Sirt-1 changed with time after SCI, and was consistent with the trend of changes in inflammatory factors. In conclusion, Sirt-1 is related to the changes of inflammatory factors after SCI, indicating that Sirt-1 may be involved in inflammation after SCI.
