ABSTRACT
Diabetic periodontitis (DP) refers to destruction of periodontal tissue and absorption of bone tissue in diabetic patients. Tumor necrosis factor receptorassociated factor (TRAF)interacting protein with forkheadassociated domain (TIFA) as a crucial regulator of inflammation activates the NFκB signaling pathway to regulate cell biological behavior. However, the function and mechanism of TIFA on DP suffer from a lack of research. In the present study, TIFA was upregulated in the periodontal tissue of a DP mouse model. In addition, the expression of TIFA in RAW264.7 cells was induced by high glucose (HG) culture and increased by lipopolysaccharide (LPS) from Porphyromonas gingivalis treatment in a timedependent manner. Knockdown of TIFA significantly reduced the levels of inflammatory cytokines, including TNFα, IL6, IL1ß and monocyte chemoattractant protein1, in HG and LPSinduced RAW264.7 cells. The nuclear translocation of NFκB p65 was induced by HG and LPS and was clearly suppressed by absence of TIFA. The expression of downstream factors Nodlike receptor family pyrin domaincontaining 3 and apoptosisassociated specklike protein was inhibited by silencing TIFA. Moreover, TIFA was increased by receptor activator of NFκB (RANK) ligand (RANKL) in a concentration dependent manner. The expression of cathepsin K, MMP9 and nuclear factor of activated T cells cytoplasmic 1 was downregulated by depletion of TIFA. RANKLinduced osteoclast differentiation was inhibited by silencing of TIFA. Meanwhile, the decrease of TIFA blocked activation of the NFκB pathway in RANKLtreated RAW264.7 cells. In conclusion, TIFA as a promoter regulates the inflammation and osteoclast differentiation via activating the NFκB signaling pathway.
