摘要

目的,2,探讨健脾解毒方对大肠癌转移能力和上皮间质转化（EMT）的影响及可能的作用机制。,方法,2,①采用细胞活力检测（CCK-8）法观察不同浓度健脾解毒方对人肠癌细胞生长的抑制作用；分别采用Transwell实验和划痕愈合实验检测健脾解毒方对肠癌细胞侵袭和迁移能力的影响；Western blot法检测健脾解毒方对细胞中EMT和Hippo信号通路相关蛋白表达的影响。②采用肠癌肺转移模型体内验证健脾解毒方对肠癌肺转移的影响及对Hippo信号通路的影响，使用苏木精-伊红（HE）染色检测肺转移灶转移情况，采用免疫组织化学法检测肺转移灶中Yes相关蛋白（YAP）的表达。③使用小分子抑制剂（XMU-MP-1）干预Hippo信号通路后，Transwell实验、划痕实验和Western blot法检测健脾解毒方对肠癌细胞侵袭转移和EMT的影响。,结果,2,①健脾解毒方以剂量和时间依赖性方式抑制人肠癌细胞的生长。与对照组比较，健脾解毒方能够明显抑制人肠癌细胞的侵袭和迁移能力（,P,<,0.05），同时健脾解毒方能够抑制肠癌细胞EMT进程；进一步研究显示健脾解毒方可以促进Hippo信号通路的激活，减少YAP入核。②体内实验的肺转移灶HE染色结果显示，健脾解毒方可以抑制肠癌肺转移灶的体积，免疫组织化学检测提示健脾解毒方可以减少转移灶中YAP的表达。③使用XMU-MP-1抑制Hippo信号通路能够增加YAP在细胞核内的积累，促进肠癌细胞的侵袭迁移能力及EMT相关蛋白的表达，促进肠癌转移；健脾解毒方可以显著减少小分子抑制剂组肠癌细胞侵袭迁移能力以及EMT的进程。,结论,2,健脾解毒方能够抑制人肠癌细胞的转移能力，其作用机制与激活Hippo信号通路有关。

Abstract

Objective,2,To investigate the effect and possible mechanism of action of Jianpi Jiedu Formula （JPJDF） on metastatic ability and epithelial mesenchymal transition （EMT） of colorectal cancer.,Methods,2,①CCK-8 cell viability assay was used to observe the inhibitory effect of JPJDF at different concentrations on the growth of human colorectal cancer cells. Transwell and scratch healing assay were used to detect the effect of JPJDF on the invasion and migration ability of colorectal cancer cells， respectively. Western blot was used to detect the effect of JPJDF on EMT and the expression of the Hippo signaling pathway-related proteins in cells. ②The effect of JPJDF on lung metastases from colorectal cancer and the Hippo signaling pathway was verified via an in-vivo study with the lung metastases model of colorectal cancer. Hematoxylin-eosin （HE） staining was used to detect lung metastases， and immunohistochemistry was used to detect the expression of YAP protein in lung metastases. ③Transwell， scratch healing assay and Western blot were used to detect the effect of JPJDF on the colorectal cancer cell invasion and metastasis and EMT after the Hippo signaling pathway was intervened with XMU-MP-1.,Results,2,①JPJDF inhibited the growth of colorectal cancer cells in a dose- and time-dependent manner. The inhibitory effect on the invasion and migration ability of colorectal cancer cells in JPJDF groups was more significant than that in control group （,P,<,0.05）， and JPJDF could inhibit the EMT process of colorectal cancer cells. Further studies showed that JPJDF could promote the activation of the Hippo signaling pathway and reduce YAP protein entry into the nucleus. ②HE staining results of lung metastases in vivo showed that JPJDF could inhibit the volume of lung metastases from colorectal cancer， and immunohistochemistry suggested that JPJDF could reduce the expression of YAP protein in metastases. ③Inhibition of the Hippo signaling pathway with XMU-MP-1 could increase the pools of YAP in the nucleus， promote the invasion and migration ability of colorectal cancer cells and the expression of EMT-related proteins， and boost metastases of colorectal cancer. JPJDF could significantly reduce the invasion and migration ability of colorectal cancer cells and slow down the progression of EMT in the group intervened with XMU-MP-1.,Conclusion,2,JPJDF can inhibit the metastatic ability of human colorectal cancer cells， and the mechanism of action is related to the activation of the Hippo signaling pathway.
