[Abstract]:Objective to study the inhibitory effect of Ouabain on the growth of esophageal adenocarcinoma cells, and to explore the effect of MKK6 and its downstream gene SOX9 on the growth of esophageal adenocarcinoma cells in vitro and tumor formation in vivo. Methods 1 the inhibition of 1043 drugs on the growth of esophageal adenocarcinoma cells in vitro was investigated. A candidate drug Ouabain was obtained, and the tumor cell growth curve in vitro and in vivo tumorigenesis test were used to verify the interference effect of the drug on the growth of esophageal adenocarcinoma cells. 2. Analysis of Ouabain treated esophageal adenocarcinoma cells by RNA sequencing technique Changes in the amount of internal gene expression, The potential target gene MKK6 was obtained, and the expression of MKK6 gene in Ouabain treated esophageal adenocarcinoma cells and tumors was detected by real-time fluorescent quantitative PCR and Western blot. 3. 3 Lentivirus transfection into esophageal adenocarcinoma cells can mediate MKK6 gene knockout. The knockout efficiency of the gene in tumor cells was detected by real-time fluorescent quantitative PCR and Western Blot. To further analyze the effect of MKK6 knockout on the growth of esophageal adenocarcinoma cells in vitro, and the role of tumorigenesis in mice based on the theory of related signal pathway. The downstream target gene SOX9 regulated by MKK6 was selected by real-time fluorescent quantitative PCR, and the effect of Ouabain and MKK6 knockout on SOX9 gene expression and protein translation was verified. 5 the CRISPR-Cas9 technique was used to knockout SOX9 in esophageal adenocarcinoma cells. By comparing the difference between blank control group and SOX9 gene knockout group in tumor cell growth curve in vitro and in vivo tumorigenesis test, To explore the role of SOX 9 in the proliferation of esophageal adenocarcinoma cells. Results 1 the inhibitory effect of Ouabain on esophageal adenocarcinoma cells: Ouabain, a candidate drug obtained by drug screening, could inhibit the proliferation of esophageal adenocarcinoma cells OE33 and OE19 in vitro. The effect of intraperitoneal injection on the transcription and translation of MKK6 gene in NSC mice by limiting the weight and volume of tumor. 2. The expression of MKK6 gene in OE33 cells induced by Ouabain was significantly decreased. The effect of MKK6 gene knockout on esophageal adenocarcinoma cells was also similar to that of the control group. The inhibitory effect of MKK6 gene knockout on esophageal adenocarcinoma cells was also similar to that of the control group. The effect of MKK6 gene knockout on esophageal adenocarcinoma cells mediated by 20% sh RNA was also similar to that of MKK6 gene knockout in vitro. Can inhibit the proliferation of esophageal adenocarcinoma cells OE33 and OE19 in vitro, Decrease the weight and volume of tumor in nude mice. 4 the regulation of SOX9 by MKK6 in esophageal adenocarcinoma cells: knockout MKK6 can decrease the expression of SOX9 in OE33 and 0E19 cells. Effects of 5SOX9 on the proliferation of esophageal adenocarcinoma cells: knockout of SOX9 gene in esophageal adenocarcinoma OE19 can inhibit its proliferation in vitro and tumorigenesis in vivo. Conclusion 1 Ouabain can inhibit the proliferation of esophageal adenocarcinoma cells in vitro and tumorigenesis in vivo. 2. Ouabain can reduce the expression of MKK6 gene and the level of protein translation in esophageal adenocarcinoma cells and mouse tumors. The knockout of MKK6 gene can inhibit the proliferation of esophageal adenocarcinoma cells in vitro. The expression of SOX9 gene and protein translation of downstream gene SOX9 can be reduced by knockout MKK6 of tumor-forming 4 gene in vivo. The knockout of SOX9 gene may affect the proliferation of esophageal adenocarcinoma cells in vitro and tumorigenesis in vivo.
