Objective:To inhibit GR expression in macrophage RAW264.7 cells of mouse by RNAi and Cre-loxP system.Methods:Two pairs of RNAi target sequence against GR gene were designed and inserted into pBS/U6-Neo vehicle.Recombinant plasmid constructed by Cre-loxP system and RNAi was identified by PCR and sequencing.The recombinant plasmid and Cre-ERT2 plasmid was transfected into the mouse macrophage RAW264.7 cells
in which GR expression was measured on mRNA and protein level respectively by RT-PCR and Western blot.Results:GR expression on mRNA and protein level was significantly inhibited by the two recombinant plasmid against GR gene.Conclusion:Combination using of RNAi and Cre-loxP system could inhabit GR expression in mouse macrophage RAW264.7 cells.
