Objective To investigate the growth inhibition of interleukin 2 receptor (IL 2R) gene transduced peripheral blood lymphocytes (PBLs) on human ovarian cancer cells Methods Interleukin 2 (IL 2) and IL 2R genes ...Objective To investigate the growth inhibition of interleukin 2 receptor (IL 2R) gene transduced peripheral blood lymphocytes (PBLs) on human ovarian cancer cells Methods Interleukin 2 (IL 2) and IL 2R genes were transfected into human ovarian cancer cell line 3AO and PBLs, respectively, using the same Fugene vector Twenty four hours later transfected and nontransfected PBLs were cocultured with transfected and nontransfected 3AO for 48 hours Cytotoxity of PBLs on 3AO was detected by the MTT assay Results The morphology of IL 2 transduced 3AO and IL 2R transduced PBLs remained unchanged 3AO cells could be transfected with the IL 2 gene and expressed IL 2 mRNA, and PBLs could be transfected with the IL 2R gene and expressed IL 2R mRNA IL 2 transduced 3AO cells enhanced their response to the cytotoxity of PBLs Furthermore, growth inhibition of PBLs to 3AO cells increased significantly when the IL 2R was transfected into PBLs and when the IL 2 gene was transfected into 3AO cells and the two were combined Conclusions IL 2R gene transduced PBLs are able to enhance their cytotoxity on IL 2 gene transduced ovarian cancer cells This method may be a new way to investigate IL 2 gene therapy for ovarian cancer展开更多
