沉默信息调节因子1调控成骨成血管功能促进颌骨缺损愈合的实验研究
Promotion of mandibular defect healing through the regulation of osteogenic and angiogenic functions by sirtuin 1
摘要
Abstract
Objective This study aims to investigate the effect of sirtuin 1(SIRT1)on osteogenic and angiogenic func-tions in mice under in vivo and in vitro conditions,as well as its effect on mandibular defect healing.Methods SIRT1 ac-tivators and inhibitors were used to intervene in MC3T3-E1 cells and mandibular defects in mice.Various methods,in-cluding cell counting kit-8(CCK-8)assay,real-time quantitative polymerase chain reaction,Western blot,alkaline phos-phatase staining,and immunofluorescence staining,were employed to study the influence of SIRT1 on the expres-sion of osteogenic and angiogenic factors in MC3T3-E1 cells,as well as the healing and osteogenic and angio-genic functions of mandibular defects in mice.Results In in vitro experiments,the activation of SIRT1 promo-ted the expression of osteogenic and angiogenic factors in MC3T3-E1 cells.In in vivo experiments,SIRT1 activation facilitated the hea-ling of mandibular defects and enhanced the osteogenic and angiogenic functions of the mandibular defects.Conversely,the inhibition of SIRT1 activity sup-pressed the aforementioned processes.Conclusion SIRT1 can promote the healing of mandibular defects by regulating the osteogenic and angiogenic functions in mice.关键词
