	1	Study of cellular immunity response of mB7-1 gene transfected mouse ovarian cancer cell line and its tumorigenecities in vivo显示文摘Objective:To investigate the cellular immunity response in vitro and the tumorigenecities in vivo of mB7 1 gene transfected murine ovarian cancer cell line.Methods:mB7 1 gene was transfected into the NuTu 19 cell line by retrovirus vector, and the expression of mB7 1 gene was confirmed by flow cytometry(FCM).NuTu 19/neo and NuTu 19/mB7 1 cells were injected subcutaneously into syngeneic Fischer 344 rats respectively,and their tumorigenecities were recorded.Proliferation indices of lymphocyte were assayed after syngenieic mixed tumor lymphocyte cultures(MTLCs).The lysis activity of CTL toward tumor cells was determined using methyl thiazolyl tetrazolium(MTT) assay.Results:Successful transfection of mB7 1 gene into NuTu 19 cell line was comfirmed with FCM.In vitro study showed that there was no obvious changes in cell growth of gene transfected cell line,compared with the cell line NuTu 19.NuTu 19/mB7 1 cells could induce more effective proliferation of effector lymphocytes(P<0.05). The lysis activity of CTL activated by NuTu 19/mB7 1 was stronger than that of NuTu 19/neo (P<0.01).Tumor sizes were smaller in the NuTu 19/mB7 1 receptance syngeneic Fischer 344 rats compared with those in the control group.Conclusion:mB7 1 genetically modified ovarian cancer cells could induce the cellular immunity response in vitro and the tumorigenecitiy of NuTu 19 cells was decreased after inoculation with the experimental vaccine.
