Effect of over expression of C-terminal Src kinase binding protein (Cbp) and Cbp palmitoylation to proliferation of T-leukemia Jurkat cell in nude mice / 中国免疫学杂志

ABSTRACT

Objective:To establish T lineage leukemia Jurkat cell mice model of over expression of C-terminal Src kinase binding protein( Cbp ) and Cbp palmitoylation and to research the effect of Cbp and Cbp palmitoylation to proliferation of Jurkat cell.Methods:Virus transfected cell of neg-EGFP,Cbp-EGFP and Cbp-m-EGFP were used in mice model.24 female BALB/c-nu mice were randomly divided into blank control group,empty virus control group,over expression of CBP group and Cbp palmitoylation group, 6 mice in each group.The nude mice were weighed in 0,1,2,3,4,5 weeks.The amount of white blood cell in peripheral blood were counted in 0, 1, 2, 3, 4, 5 weeks.The proliferation of Jurkat cell in peripheral blood of mice were observed by laser confocal microscope.The pathological changes of liver were observed using HE staining.The proliferation of Jurkat cell in the bone marrow and peripheral blood of mice were detected with flow cytometry.Results:The weight of mice in over expression of Cbp group was less than that in blank control group,but higher than that in empty virus control group and Cbp palmitoylation group.The weight of mice in Cbp palmitoylation group was less than that in blank control group,empty virus control group and over expression of Cbp group.The amount of white blood cell in peripheral blood and proliferation of Jurkat cell in liver, bone marrow and peripheral blood of mice in over expression of Cbp group was higher than that in blank control group, but less than that in empty virus control group and Cbp palmitoylation group.The amount of white blood cell in peripheral blood and proliferation of Jurkat cell in liver, bone marrow and peripheral blood of mice in Cbp palmitoylation group was higher than that in blank control group,empty virus control group and over ex-pression of Cbp group.Conclusion:Over expression of Cbp and Cbp palmitoylation in T lineage leukemia Jurkat cell mice model was established.Over expression of Cbp has inhibitory effect on the proliferation of Jurkat cell.Cbp palmitoylation has promotable effect on the proliferation of Jurkat cell.
