Objective:To constructive and identify plasmid vector of microRNA on pneumocystis carinii(PC)major surface glycoprotein (MSG)gen’s upstream conserved sequence(UCS)
then we researched its effect after the recombinant plasmid was transfected into PC. Methods:microRNA oligonucleotides targeting PC MSG-UCS gene were chemically synthesized and inserted into plasmid vector pcDNA? 6.2-GW/EmGFPmiR after annealing.then the recombinant plasmid was transfected into PC by liposome in vitro.The PC MSG-UCS mRNA expression was detected by RT-PCR and the fine structure of PC was observed by electronmicroscope.Results:Gel electrophoresis and DNA sequencing showed that the recombinant plasmid containing the correct and full microRNA oligonucleotide
and it could knock down the expression of mRNA in PC in vitro
it could also destroy PC.Conclusion:The microRNA plasmid
pPC-UCSm
was constructed successfully
and it could knock down the expression of PC in vitro.
