Abstract:
Objective: To investigate the influence of transfection of TCRVJ37.1 gene in cytotoxicity of PBMC of healthy donor to breast cancer cell line MCF-7/S. Methods :pcDN*31vp'1 packaged by lipofectamine were transfected to healthy donor's PBMC,Flow Cytometer Analysis and MTT Colorimetric Assay were used respectively to test the expression of pcDNA3.1VB7.1 gene and the cytotoxicity of PBMC before and after gene transfection of healthy donor to breast cancer cell line MCF-7/S. Results: The expression of TCRVJ37.1 gene after transfection was obviously higher.There was distinguish differences of cytotoxicity before and after gene transfection. Conclusion:The modified healthy donor's PBMC by TCR gene could have stronger cytotoxicity to breast cancer cell line.
