ABSTRACT
Aim To construct the eukaryotic expression vector of hIL-24 cDNA,and express it in CHO cells and detect its anti-tumor effect of recombinant hIL-24 protein.Methods Constructed pcDNA3-hIL-24 was identified by endonucleases digestion & PCR.The recombinant expression plasmids were transfected into CHO cells,human hIL-24 expressed in CHO cells was detected with RT-PCR.The apoptosis-inducing activities of recombinant protein hIL-24 was tested by MTT assay,Hoechst& FCM assay,and the expression of IL-6 and IFN-? from PBMC induced by rhIL-24 was tested by ELISA.Results The eukaryotic expression vector pcDNA3-hIL-24 was constructed correctly.Stable expression of human IL-24 in CHO cells was identified with RT-PCR.The apoptosis of A549 cells induced by hIL-24 was proved by Hoechst & FCM assay,and the expression of IL-6 and IFN-? from PBMC induced by rhIL-24 was identified with ELISA.Conclusion The successful stable expression & experimental study of apoptosis effect of human IL-24 gene lay the foundation for the further study of molecular mechanism of hIL-24 on anti-tumors and potential application.
