摘要： 目的探讨槐耳能否影响结直肠癌增殖和凋亡及其机制。方法通过细胞增殖实验检测槐耳对结直肠癌HCT8和HT29细胞增殖的影响,流式细胞术检测槐耳对细胞凋亡的影响,RT-qPCR检测槐耳对P85α mRNA表达水平影响,Western blot检测槐耳对PI3K/AKT通路蛋白P85α、p-AKT和AKT,凋亡蛋白BAX、BCL-2、Cleaved caspase-3和Cleaved caspase-9以及增殖蛋白CDK4和CyclinD1表达量的影响。结果细胞增殖实验结果显示,槐耳能降低HCT8和HT29细胞的存活率,且存活率随浓度增加而递减。不同浓度槐耳作用下HCT8和HT29细胞凋亡率显著升高,即槐耳能促进HCT8和HT29的凋亡,且凋亡率随浓度增加而递增。不同浓度槐耳作用下,HCT8和HT29细胞中P85α mRNA表达水平显著下调,即槐耳能抑制P85α基因表达水平,且其表达水平随浓度增加而降低。Western blot表明,槐耳可显著降低P85α、p-AKT/AKT、BCL-2、CDK4、CyclinD1的表达量,提高BAX、Cleaved caspase-3、Cleaved caspase-9的表达量（P均<0.05）。结论槐耳能降低结直肠癌HCT8和HT29细胞存活力和促进细胞凋亡,其机制可能与PI3K/AKT信号通路有关。

Abstract: Objective To investigate whether huaier can induce apoptosis of colorectal cancer (CRC) cells and its possible mechanism. Methods CCK8 assays detected the viability of HCT8 and HT29 cells with different concentration of huaier. Flow cytometry detected the apoptosis of HCT8 and HT29 cells, and the gene expression lever of P85α mRNA was detected by RT-qPCR assays. Western blot assays detected the expression lever of pathway protein P85α, p-AKT and AKT, apoptosis protein BAX, BCL-2, Cleaved caspase-3 and Cleaved caspase-9, and proliferating protein CDK4 and CyclinD1 on HCT8 and HT29 cells with different concentration of huaier. Results Huaier could reduce the viability of HCT8 and HT29 cells, and the viability were decreasing with the increasing concentration. The apoptosis rates of HCT8 and HT29 cells with different concentration of huaier were increased observably. It showed that huaier could increase the apoptosis rates of HCT8 and HT29 cells, and the apoptosis rates were increasing with the increasing concentration. The expression lever of P85α mRNA in HCT8 and HT29 cells were decreased observably. It showed that huaier could decrease the expression lever of P85α mRNA, and the expression lever of P85α mRNA were decreasing with the increasing concentration. Western blot assays showed that huaier can inhibit the expression lever of P85α, p-AKT/AKT, inhibit the expression of BCL-2, CDK4 and CyclinD1, and promote the expression lever of BAX, Cleaved caspase-3 and Cleaved caspase-9. Conclusion Huaier can inhibiting the proliferation and inducing the apoptosisof HCT8 and HT29 cells, and its mechanism may be related with PI3K/AKT signaling pathway.
