转移仍然是治疗癌症的一个重大挑战。为了开发更有效的治疗方法,需要更好地了解转移的分子机制。在这里,我们展示了人类乳腺肿瘤生物标记物miR-30c通过靶向编码Twinfilin 1(TWF1)和Vimentin(VIM)的细胞骨架网络基因来调节侵袭。VIM和TWF1都被证明调控上皮向间充质转化(EMT)。与TWF1类似,VIM也调节F-肌动蛋白的形成,F-肌动蛋白是细胞向侵袭性更强的间充质表型转变的关键成分。为了进一步研究TWF1通路在乳腺癌中的作用,我们发现IL-11是TWF1调控乳腺癌细胞侵袭和STAT3磷酸化的重要靶点。MiR-30c-VIM/TWF1信号通路也与乳腺癌患者的临床预后有关。
Metastasis remains a significant challenge in treating cancer. A better understanding of the molecular mechanisms underlying metastasis is needed to develop more effective treatments. Here we show that human breast tumor biomarker miR-30c regulates invasion by targeting the cytoskeleton network genes encoding Twinfilin 1 (TWF1) and Vimentin (VIM). Both VIM and TWF1 have been shown to regulate epithelial-to-mesenchymal transition (EMT). Similar to TWF1, VIM also regulates F-actin formation, a key component of cellular transition to a more invasive mesenchymal phenotype. To further characterize the role of the TWF1 pathway in breast cancer, we found that IL-11 is an important target of TWF1 that regulates breast cancer cell invasion and STAT3 phosphorylation. The miR-30c-VIM/TWF1 signaling cascade is also associated with clinical outcome in breast cancer patients.
