XPG基因遗传变异与上皮性卵巢癌铂类化疗预后相关性研究

目的探讨XPG基因单核苷酸多态性(SNPs)与上皮性卵巢癌铂类化疗预后的关系。方法通过Haploview软件筛选出XPG基因9个标签SNPs(tag SNPs)。连接酶检测反应技术检测2002年3月至2009年12月在河北医科大学第四医院进行手术治疗的239例上皮性卵巢癌患者外周血DNA XPG基因9个tag SNPs的基因型频率分布情况。采用生存分析评估XPG基因SNPs与上皮性卵巢癌患者临床预后的关系。患者临床预后的判定指标包括患者对铂类化疗反应(TR)、疾病无进展生存期(PFS)和总生存期(OS)。结果统计学分析显示:XPG基因rs1047768C/T和rs2296147C/T多态可能与确诊时年龄≥50岁的卵巢癌患者临床预后相关。即与rs1047768 T/T基因型相比,rs1047768C等位基因降低了患者铂类抵抗、疾病复发和死亡的风险(TR:OR=0.49,95%CI 0.24~0.98;PFS:HR=0.57,95%CI 0.38~0.87;OS:HR=0.56,95%CI 0.34~0.94);与rs2296147 T/T基因型相比,rs2296147C等位基因降低上皮性卵巢癌患者疾病复发和死亡的风险(PFS:HR=0.63,95%CI 0.41~0.98;OS:HR=0.50,95%CI 0.28~0.87)。结论 XPG rs1047768C/T和rs2296147C/T多态可能是确诊时年龄≥50岁卵巢癌患者临床预后的分子标志物。

转染CD40配体的卵巢癌细胞株OVHM抗卵巢癌肝转移机制的研究

Objective To examine the in vivo anti-metastatic effect of enhanced expression of CD40L cDNA in murinc ovarian cancer OVUM cells (CD4OL-OVHM) injected into the spleen on liver metastasis in mice. Methods OVUM cells were inoculated into the spleen of 6 ～ 8 week-old female B6C3F1 (C57BL/6N × C3H/He) mice. The established liver metastasis was identified by histopathology (HE staining). OVUM cells, DNA-pMKITneo-OVHM cells or CD40L-OVHM cells were inoculated into the spleen of female B6C3F1 mice and the expressions of CD11c in splenic cells were detected by flow cytometry. The specific cytotoxicity of splenic cells was detected by MTT assay, and the serum cytokines of IFN-γ, TNF-α, IL-12, IL4 and IL-10 of the mice were measured by enzyme linked immunoabsorbent assay. The liver metastases and the survival time of the mice were also recorded. Results The mouse models with liver metastasis by injecting tumor cells into the spleen of mice were established. The expression of CD11c and the specific killing rote in CD40L-OVHM cells group was significantly higher than that in the OVHM cells group and DNA-pMKITneo-OVHM cells group. The expressions of IFN-γ, TNF-α and IL-12 in the CD40L-OVHM cells group were much more increased than OVHM cells group and DNA-pMKITneo-OVHM cells group, but the expressions of IL-4 and IL-10 in the CD40L-OVHM cells group were decreased significantly (P < 0.05). The average weights of livers and spleens of mice in CD40L-OVHM cells group were significantly lower than those of DNA-pMKITneo-OVHM cells group and OVHM cells group. The survival time of mice in CD40L-OVHM cells group was also significantly longer than that in the OVHM cells group and DNA-pMKITneo-OVHM cells group (P < 0.05). Conclusion The data directly demonstrate that the expression of CD40L in ovarian cancer cells (CD40L-OVHM) can enhance the proliferation and differentiation of dendritic cells in the spleen and induce specific cytotoxic effect of T cells in the spleen, and may regulate the immune function of peripheral blood cells and the immune balance between Thl cells and Th2 cells, which maybe the possible mechanism induced by CD40L in mice inhibiting the development of liver metastasis.
