简介:摘要骨质疏松症(osteoporosis,OP)的病因主要为由成骨细胞(osteoblast,OB)介导的骨形成与由破骨细胞(osteoclast,OC)介导的骨吸收之间的平衡失调,骨形成/骨吸收比例降低,导致进行性骨丢失。Wnt1诱导信号通路蛋白1(Wnt1-inducible signaling pathway protein 1,WISP1)是调控OB与OC分化及活性的关键调节因子,在骨骼发育及骨折愈合过程的各阶段表达,并通过诱导干细胞向OB分化、提高OB活性及抑制OC分化与形成等方式促进骨形成、抑制骨吸收,从而提高骨量。WISP1在骨骼系统的促进成骨作用使其成为OP潜在的治疗靶点。
简介:摘要:WNT1诱导信号通路蛋白1 (Wnt1 inducible signaling pathway protein 1,WISP1) 是一种富含半胱氨酸的蛋白质,属于CCN 蛋白家族。越来越多的研究表明WISP1在各种人类恶性肿瘤中发挥不同的生物学功能。新的研究证据显示WISP1蛋白与胃癌细胞增殖、凋亡、侵袭和转移密切相关。在这篇综述中,我们描述了WISP1蛋白在胃癌中的生理功能以及其如何参与胃癌发生进展过程。此外,我们讨论了WISP1有望成为胃癌的诊断标志物和/或治疗新靶点。
