2.Resveratrol attenuates LPS-induced cell injury and TLR4/NF-κB activation in human periodontal ligament cells
Journal of Practical Stomatology 2017;33(1):88-91
Objective:To investigate the protective effect of resveratrol on lipopolysaccharide (LPS)-induced cell injury in human periodontal ligament cells(hPDLCs).Methods:hPDLCs were cultured and identified.The cultured hPDLCs were divided into 5 groups:control group and LPS(10 μg/ml) + RES(0/30,60 and 90 μmol/L respectively) groups.The cell proliferation was detected by MTI assay.The secretion of TNF-α and IL-6 of hPDLCs was detected by ELISA kit.The expression of TLR4/NF-κB mRNA and protein was determined by PCR and Western blot analyses,respectively.Results:The cultured cells were negative for cytokeratin and positive for vimentin staining.Compared with the control group,cell proliferation was decreased,the secretion of TNF-α/IL-6 levels and the expression of TLR4/NF-κB mRNA and protein were increased after treatment with LPS.Whereas,with 30-90 μmol/L resveratrol pretreatment,the proliferation ability of hPDLCs was enhanced(P < 0.05),the secretion levels of TNF-α and IL-6 and the expression of TLR4/NF-κB mRNA and protein were reduced (P < 0.01) in a dose-dependent manner.Conclusion:Resveratrol may attenuate LPSinduced cell injury by inhibiting TLR4/NF-κB pathway in hPDLCs.
