  • Study on Relationship Between RasTG and Pancreatic Carcinoma

    ObjectiveTo study the expressions of Ras trapping to Golgi (RasTG) genes in pancreatic carcinoma tissues and to observe the growth, proliferation and the impact of tumors formation of human pancreatic cancer cells (PANC-1), and to explore its mechanism. MethodsMade PANC1 as a target to research, transfected RasTG genes into PANC-1, used RNAi technology and observed the growth, proliferation and the impact of tumors formation of the cells. Meantime, contrasted the RasTG expressions between pancreatic ductal cancer and adjacent tissue by tissue microarray technology. Results①The expression of RasTG gene in tissues was not very differential, which was higher in the brain, liver, and adrenal gland. ②The expression of RasTG protein in pancreatic ductal carcinoma was significantly higher than that in adjacent tissues (Plt;0.05). ③After RasTG RNAi in PANC-1 cells, the ability of growth and proliferation were decreased. ④The ability of tumors formation in PANC-1 cells after RNAi was decreased, carcinoma’s volume of transfected group was significantly smaller than that in the nontransfected group (Plt;0.05). ConclusionsRasTG gene is widely distributed in animals. RasTG protein in pancreatic carcinoma tissues is higher than that in adjacent tissues. The ability of proliferation, transformation and tumors formation in PANC-1 cells after RNAi of RasTG gene are restrained, RasTG gene is a positive regulatory factor.
