细胞外基质(ECM)可以通过AKT介导的细胞凋亡抑制诱导化疗耐药。在这里,我们表明,ECM蛋白TGFBI(转化生长因子β诱导)的损失足以诱导特异性耐药紫杉醇和有丝分裂纺锤体异常卵巢癌细胞。用重组TGFBI蛋白处理的紫杉醇耐药细胞显示通过FAK和Rho依赖性微管稳定化的紫杉醇敏感性的整合素依赖性恢复。一项前瞻性临床试验中紫杉醇治疗的卵巢癌中TGFBI的免疫组织化学染色显示,紫杉醇诱导的细胞毒性的形态学变化仅限于TGFBI强表达的区域。这些数据表明ECM可以通过调节微管稳定性来介导紫杉烷敏感性。
The extracellular matrix (ECM) can induce chemotherapy resistance via AKT-mediated inhibition of apoptosis. Here, we show that loss of the ECM protein TGFBI (transforming growth factor beta induced) is sufficient to induce specific resistance to paclitaxel and mitotic spindle abnormalities in ovarian cancer cells. Paclitaxel-resistant cells treated with recombinant TGFBI protein show integrin-dependent restoration of paclitaxel sensitivity via FAK- and Rho-dependent stabilization of microtubules. Immunohistochemical staining for TGFBI in paclitaxel-treated ovarian cancers from a prospective clinical trial showed that morphological changes of paclitaxel-induced cytotoxicity were restricted to areas of strong expression of TGFBI. These data show that ECM can mediate taxane sensitivity by modulating microtubule stability.
