目的:探讨人非ATP酶依赖性调节颗粒13(hRpn13)通过泛素-蛋白酶体通路(UPP)途径对人牙周膜细胞(PDLC)的作用,从而揭示其对PDLC增殖、分化和功能的调节作用。方法通过转染敲除来改变PDLC中hRpn13的表达后,用MTT法观测细胞形态,4′,6-二脒基-2-苯基吲哚(DAPI)来检测细胞增殖情况,通过检测碱性磷酸酶(ALP)和Ⅰ型胶原纤维的分泌情况来检测细胞成骨分化情况,最后通过检测NF鄄κB受体活化子配体(RANKL)、骨保护素(OPG)、泛素化蛋白的改变来研究hRpn13对PDLC功能的调节作用及其可能机制。结果 hRpn13对成纤维细胞的增殖和ALP的活性,Ⅰ型胶原蛋白以及RANKL、OPG的表达起到了负性调节作用,同时hRpn13使泛素化蛋白聚集减少。结论 hRpn13可以通过影响UPP通路来调节成纤维细胞的增殖、分化和功能。

Objective To investigate the role of human regulatory particle non-ATPase 13 (hRpn13) on the ubiquitin-26S proteasome pathway in human periodontal ligament cells (PDLCs) and the effects of hRpn13 on cell proliferation, differentiation, and function of human PDLCs. Methods The effects of altered hRpn13 gene expression on cell proliferation , apoptosis and differentiation of PDLCs were examined by MTT assay, DAPI staining, ALP ELISA Kit and elevation of collagenⅠ. Andκappa B ligand/osteoprotegerin (RANKL/OPG) and ubiquitin gene expression was detectd by western blot. Results hRpn13 played a negative role in the proliferation, ALP activity and expression of collagenⅠ, RANKL and OPG. Moreover, the expression of ubiquitined protein decreased with over expression of hRpn13. Conclusion HRpn13 can influence cell proliferation, differentiation, and function of human PDLCs by the ubiquitin-26S proteasome pathway .
