ABSTRACT
Objective To explore the effects of miRNA-218 on renal cell carcinoma of nude mice in vivo.Methods The pcDNA3.1-miR-218 and its control negative plasmids were stably transfected into renal cell carcinoma cell line A498 and 769-P.These cells were inoculated into nude mice in different groups to observe the changes of body and tumor and to detect the expression of miR-218 in the tissues of nude mice.Results In the A498 cells + pcDNA3.1-miR-218 transfected group,the weight loss of tumor bearing nude mice after 25 days was lower than that in the control group,and the tumor volume was smaller than that in the control group after 10 days (P < 0.05).In the 769-P cells + pcDNA3.1-miR-218 transfected group,the weight loss of tumor bearing nude mice was lower than that in the control group after 19 days,and the tumor volume was smaller than that in control group after 10 days (P < 0.05).The expression of miRNA-218 in bearing nude mice with A498 cells or 769-P cells transfected by miRNA-218 was significantly higher than that in the control group,and the difference was statistically significant (P < 0.05).Conclusion Up-regulation of miRNA-218 expression can inhibit the growth of renal cell carcinoma of nude mice in vivo.
