项目摘要
In this study, we report that large-magnitude (12%) cyclic stretch induced Ca2+ influx in MC3T3-E1 osteoblasts, which subsequently activated ASK1 MAP3K. The activated ASK1-JNK lead to transiently enhanced expression of FGF-inducible 14 (Fn14, a member of the TNF receptor superfamily) gene. Cells with enhanced expression of Fn14 subsequently acquired sensitivity to the ligand of Fn14, TNF-related weak inducer of apoptosis, and underwent apoptosis. On the other hand, ASK1-p38 pathway induced expression of monocyte chemoattractant protein-3 (MCP-3) gene, which promoted chemotaxis of pre-osteoclasts. These results suggest that ASK1-JNK/p38 pathways contribute to the mechanism of mechanical overloading-induced bone resroption via cytokine-related gene expression.
在这项研究中,我们报告说,大幅度(12%)循环拉伸诱导 MC3T3-E1 成骨细胞中 Ca2+ 流入,随后激活 ASK1 MAP3K。激活的 ASK1-JNK 导致 FGF 诱导型 14(Fn14,TNF 受体超家族成员)基因的表达短暂增强。 Fn14表达增强的细胞随后获得对Fn14配体(TNF相关的细胞凋亡弱诱导剂)的敏感性,并经历细胞凋亡。另一方面,ASK1-p38途径诱导单核细胞趋化蛋白3(MCP-3)基因的表达,促进前破骨细胞的趋化性。这些结果表明 ASK1-JNK/p38 通路通过细胞因子相关基因表达参与机械超载诱导骨再吸收的机制。
