Abstract:
Objective:To construct recombinant lentivirus and adenovirus which regulate the expression of c-Cbl gene and evaluate their efficacy.Methods:The interference lentivirus and overexpressed adenovirus targeting human c-Cbl gene were constructed by gene recombination technology.Quantitative PCR and western blotting were used to detect the expression changes in c-Cbl gene and its transcription after leukemia cells(HL60,THP1)were infected by virus.Results:Three recombinant interfering lentiviral vectors targeting human c-Cbl genes to successfully constructed and were identified by DNA sequencing,and the titers of the packaged viruses were all greater than 1 x 108 TU/ml.Among them,shRNA-2 lentivirus had the highest interference efficiency,and the expression of c-Cbl gene and CBL protein were decreased about 95%and 60%respectively after leukemia cells were infected with shRNA-2;In addition,the recombinant overexpression adenovirus targeting human c-Cbl gene was packaged successfully with the virus titer greater than 1 x 109 TU/ml.When leukemia cells were infected with adenovirus,the expression of c-Cbl gene and CBL protein were up-regulated about 10 times and 1.5 times respectively.Conclusion:Both recombinant interfering lentivirus and overexpression adenovirus can efficiently infect leukemia cells and affect the expressions of c-Cbl gene and CBL protein.It will lay a preliminary foundation for the subsequent study on the function of c-Cbl gene in tumor cells.
