ABSTRACT
Objective:To investigate the effects of Porhyromonas endodontalis(P.e)liopolysaccharide(LPS)on the expression of IL-23mRNA and protein in mouse osteoblasts MC3T3-E1 and the role of phosphatidylinositol 3-Kinases (PI3K)signaling pathway in this process.Methods:MC3T3-E1 cells were treated with different concentrations of P.e LPS for different hours,or pretreated with LY294002,a special PI3K inhibitor.The IL-23 mRNA and protein expression levels were detected by real-time PCR and Western blot respectively.Results:The level of IL-23 mRNA increased in MC3T3-E1 cells with the increase of concentration and the treatment time of P.e LPS(P <0.05).The IL-23 protein expression was increased by P.e LPS in a time dependent manner(P <0.05).The mRNA and protein of IL-23 decreased(P <0.05)after pretreatment with LY294002.Conclusion:P.e LPS can induce the expression of IL-23 mRNA and protein in MC3T3-E1 cells,and the PI3K signaling pathway may play a part in this process.
