diabetic periodontitis (dP) refers to destruction of periodontal tissue and absorption of bone tissue in diabetic patients. Tumor necrosis factor receptor-associated factor (TraF)-interacting protein with forkhead-associated domain (TIFA) as a crucial regulator of inflammation activates the nF-κB 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 time-dependent manner. Knockdown of TiFa significantly reduced the levels of inflammatory cytokines, including TnF-α, il-6, il-1β and monocyte chemoattractant protein-1, in HG and lPS-induced raW264.7 cells. The nuclear translocation of nF-κB p65 was induced by HG and lPS and was clearly suppressed by absence of TiFa. The expression of downstream factors nod-like receptor family pyrin domain-containing 3 and apoptosis-associated speck-like protein was inhibited by silencing TIFA. Moreover, TIFA was increased by receptor activator of NF-κB (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. ranKl-induced osteoclast differentiation was inhibited by silencing of TiFa. Meanwhile, the decrease of TiFa blocked activation of the NF-κB pathway in ranKl-treated raW264.7 cells. in conclusion, TiFa as a promoter regulates the inflammation and osteoclast differentiation via activating the nF-κB signaling pathway.
