西黃丸抑制胃癌細胞增殖及其血管生成擬態(tài)形成的機制探討
[Abstract]:BACKGROUND: China is a high incidence of gastric cancer. The morbidity and mortality of gastric cancer are in the forefront of the incidence and mortality of the tumor in China. The formation of angiogenesis is the newly discovered form of angiogenesis in recent years. It is closely related to the poor prognosis of gastric cancer. The hypoxic micro-environment is one of the main factors to promote the formation of tumor angiogenesis, and has a close relationship with the syndrome of blood stasis and poison. The anti-cancer Nifang pill has the effects of promoting blood circulation and removing toxic materials and inhibiting various tumors, and we have speculated that the possible mechanism of the western yellow pill with the effects of removing toxic substance and promoting blood circulation can be realized by regulating the hypoxic microenvironment and further inhibiting the formation of the tumor blood vessel. Objective: To study the mechanism of XHuangwan to regulate the hypoxic microenvironment and to inhibit the formation of tumor angiogenesis, and to explore the internal target of the anti-tumor of Xihuang Wan and enrich the connotation of the blood-activating and detoxicating method in the treatment of the tumor. Methods: (1) Experimental group: blank group, Xihuang pill group, HIF-1 inhibitor (2-ME) group and combination group; (2) human gastric cancer MGC-803 cell line and CCK-8 method were used in vitro to detect the inhibition of the proliferation of the tumor cells, and the AV-PI method was used to detect the effect of Xhuang pill on the apoptosis of the tumor cells. The effect of sihuang pill on the cell cycle of the tumor was detected by RNA enzyme method. In vivo, the tumor model of MGC-803 was established by Balb/ c nude mice, and the effect of Xihuang pill on the tumor volume and quality of the transplanted tumor in nude mice was observed and measured. (3) The hypoxic cell culture model was established by using the hypoxia workstation. The model of the in vitro tumor cell model was established by three-dimensional culture, and the number of tubes in each group was calculated by using a PAS-CD31 immunochemical-immunohistochemical double-staining method in vitro. (4) RT-qPCR, Western-blot and IHC were used to detect the expression of VE-Cadherin, EphA2, MMP-2 and the expression of mRNA, p-EphA2 protein, HIF-1, Twin1 and mRNA in the blood vessels by RT-qPCR, Western-blot and IHC. And (5) screening the anti-tumor and regulating the related genes of the hypoxia pathway by using the HTA2.0 chip, and carrying out RT-qPCR verification. Results: (1) Xihuang Wan can inhibit the proliferation of MGC-803 cells, and show the concentration and time-dependence, IC50:24 h is 50.424. mu. g/ ml,48 h is 35.129.mu. g/ ml, 72h is 28.191. mu. g/ ml, and the growth of transplanted tumor in nude mice is inhibited. At the same time, it can promote the apoptosis of MGC-803 cells and block the cell cycle in G0/ G1 phase. (2) In vitro and in vivo MGC-803 cell-like tube formation model, Xihuang pill can significantly inhibit the formation of the in vitro hypoxia condition and the in-vivo MGC-803 pseudo-state pipeline, which is similar to that of 2-ME, and the combination group has the strongest inhibition effect on the formation of the quasi-state pipeline. (3) The expression of VE-Cadherin, MMP-2 and the expression of p-EphA2 in the in-vivo and in-vitro VE-Cadherin and MMP-2 can be reduced and the expression of p-EphA2 can be reduced in vivo and in vitro. The binding group could decrease the expression of EphA2 mRNA, but could not significantly affect the expression of its protein. The expression of HIF-1 and Twin1 mRNA and protein in the in vitro expression of HIF-1 and Twin1 were decreased in Xhuang Pills,2-ME and combination group. (4) The gene chip of HTA2.0 was used to screen the possible pathway target of XHuangwan, and it was found that the expression of 628 genes could be reduced significantly and the expression of 88 genes was up-regulated. Significant down-regulation of 9 lncRNA expression, up-regulation of 11 lncRNA expression, and a significant effect on 54 signal pathways. in combination with that result of the above research, the hypoxia signal path and the cell cycle signal path are selected for verification, and the expression of the protein mTOR on the HIF-1 protein can be reduced, the expression of the post-translational modification protein PHD2 and the VHL protein gene is promoted, and the cell cycle related protein (SMC3, CDC25C, CDC6, MCM3) gene expression level. Conclusion: Xihuang Wan can inhibit the expression of hypoxia-related mTOR-HIF-1-Twistl signal, (2) promote the expression of hypoxia-related protein PHD2 and VHL, (3) inhibit the expression of the related protein VE-Cadherin, MMP-2 and EphA2 protein phosphorylation in the blood vessel, and (4) inhibit the expression of SMC3, CDC25C and CDC6. The cell cycle-related gene expression, such as MCM3, can inhibit the proliferation of MGC-803 cells and the formation of angiogenesis in human gastric cancer.
