探讨外源性生长因子-β1与外源性血小板衍生生长因子BB联合应用对牙周组织破骨细胞内Pyk2表达的影响。方法 160只SD大鼠随机分为2组,建立正畸牙移动模型。A组注射含rhTGF-β1与rhPDGF-BB的混合液 0.1 mL,B组注射相同容量的PBS。加力后1、4、7、10、14 d,分别处死每大组的1小组大鼠。测量牙移动距离变化,TRAP染色行破骨细胞计数,Pyk2蛋白和基因水平分别用免疫组织...
Dynamin and PTP-PEST cooperatively regulate Pyk2 dephosphorylation in osteoclasts
signaling Tyrosine kinase Osteoclasts

The proliferation and differentiation of osteoblast (OB) precursors are essential for elaborating the bone-forming activity of mature OBs. However, the mechanisms regulating OB proliferation and funct...
Signaling via the Pyk2-Src-Cbl complex downstream of integrins contributes to the assembly, organization, and dynamics of podosomes, which are the transient adhesion complexes of highly motile cells s...
Defective microtubule-dependent podosome organization in osteoclasts leads to increased bone density in Pyk2W22;/W22; mice
