Abstract

Abstract: PURPOSE: To investigate the protective effect and mechanism of resveratrol on oxidative stress of MC3T3-E1. Methods: The levels of reactive oxygen species in the cells were observed by fluorescence microscope and flow cytometry. The expression of SOCS-1 protein was detected by Western blot. SOCS-1 transient transfected cell line was established, and the levels of reactive oxygen species in transfected cells were observed by fluorescence microscopy and flow cytometry. The data were analyzed using SPSS22.0 software package. Results: The level of ROS in LPS group was significantly higher than that in the blank group and LPS+RES group (P<0.05). The expression level of SOCS-1 protein was increased after LPS stimulation for 30 min (P<0.05). The level of ROS in the siSOCS-1+LPS+RES group was significantly higher than that in the untransfected group (P<0.05). Conclusions: Resveratrol may counteract LPS-mediated oxidative stress in MC3T3E1 cells by modulating SOCS-1 protein.
