Objective:To discuss the depressed expression of BUB1 gene in trophoblastic cells by microRNA.Methods:Endogenous BUB1 mRNA level was compared by using quantitative real-time PCR before and after transfected with microRNA plasmid; and the Bub1 protein level was compared by western blot.Results:Ratio of BUB1 mRNA/GAPDH mRNA of control group was 0.1960±0.0688
and after transfected with microRNA recombinant plasmid was 0.1968±0.0689 and 0.1962±0.0670 respectively.Statistical study of samples showed they have no instinct different;otherwise the protein level was significantly decreased after transfected with microRNA plamid.Conclusion:This study established microRNA can control gene expression in mammalian cells at translation level
it is a good foundation to study on the control of gene expression.
