Syntenin and Pick1(PDZ-domain proteins) have been reported to bind to ephrinB ligands.However,there is no data related to whether ephrinB ligands,located on the membrance of osteoclasts,regulate expression levels of syntenin and Pick1,following activation by EphB receptors.RAW264.7 cell line was used as osteoclast precursors,which can differentiate into osteoclast induced by RANKL.Western blot analysis and/or immunofluorescence staining revealed that not only syntenin and Pick1,but also ephrinB2 were promin...

近十几年,随着Eph受体基因的克隆成功[1]及其Ligands配体的识别[1-3],有关这些分子在有机体生长发育及疾病变化中的重要作用得到了广泛的研究.Eph(erythropoietin-producing hepatocyte kinases)受体是酪氨酸蛋白激酶受体家族中最大的亚家族,ephrin(Eph受体相互作用蛋白,Eph re
