ABSTRACT
OBJECTIVE@#To observe the effect of Bruton's tyrosine kinase (BTK) on the proliferation and differentiation of osteoclasts and to explore the mechanism of BTK on bone destruction in periapical periodontitis.@*METHODS@#After RAW264.7 cells induced with 100 ng·L⁻¹ receptor activator for nuclear factor-κB ligand (RANKL) for 5 days, osteoclast induction was confirmed by light microscopy, tartrate-resistant acid phosphatase (TRAP) staining, and quantitative real-time PCR (RT-qPCR). Then, BTK-small interfering RNA (BTK-siRNA) was transfected into cells induced for 5 days. After 24 h, the expression of TRAP mRNA was measured using RT-qPCR, and the proliferation and differentiation of osteoclasts were detected using CCK-8 and TRAP activity assay. Statistical analysis was performed.@*RESULTS@#After RAW264.7 was induced with RANKL for 5 days, a large number of round, ellipse, irregularly protuberant, and TRAP-positive macrophages were observed under light microscopy. The expression of TRAP mRNA significantly reduced after 24 h of BTK-siRNA transfection (P<0.05). The detection of CCK-8 and TRAP activities showed that the proliferation and differentiation of osteoclasts significantly decreased (P<0.05).@*CONCLUSIONS@#Silencing of BTK can inhibit the proliferation and differentiation of osteoclasts. BTK can be used as a new target for the inhibition of osteoclasts.
