Abstract: Objective · To explore the effects of Indoxyl sulfate (IS) on proliferation activity, of inflammatory factors and reactive oxygen species (ROS) in human periodontal ligament cells (hPDLCs). Methods · The primary hPDLCs were culturedusing tissue explant method in vitro. MTT assay was employed to evaluate the effect of IS on proliferation activity of hPDLCs. The mRNA and protein s of IL-1β, IL-6, and IL-8 were detectedusing real-time PCR and ELISA assay. DCFDA fluorescence probe was used to detect intracellular ROS and ROS in the cytoplasm under fluorescence microscope. Results · The viability of hPDLCs was inhibitedIS at the concentration of 125 μmol/L on 24, 48 and 72 hours. The inhibitory effect was presented in a dose- and time- dependent manner. IS could upregulate the mRNA and protein of inflammatory cytokines including IL-1β, IL-6 and IL-8 as well as promote ROS in hPDLCs. Conclusion · IS may play an important role in the association between chronic kidney diseases and periodontitis through inhibiting the activity of hPDLCs, promoting the of inflammatory cytokines and increasing intracellular ROS level.
