In vivo, CXCR4-A549 and A549 cells were injected subcutaneously into nude mice(each group in 6).Four weeks later the mice were scarified and the tumors in situ and the lungs were taken out to be examined histologically.(3) Th cell cycle distribution was measured by flow cytometry to analyse the effect of SDF-1/CXCR4 in the cell proliferation and atoposis. The changes of the intracellular calcium concentration after SDF-1 activation were aslo measured by flow cytometry. Western blot was used to anlayse the phosphorylation of AKT and ERK, and the expression of MMP-2 and VEGF-C.

Cerevisiae have found that bZIP proteins play a role in yeast anti-oxidation. at3g51960, the transcription factor found in plants, is highly homologous to that of yeast. To examine the in vivo role of at3g51960, the overexpression and silencing vectors were constructed respectively. By using flower dip-dye, the binary expression vectors, pCAMBTA3301: at3g51960 and pCAMBTA3301: at3g51960Promoter, as well as vectors pCAMBTA3301: at3g51960-GFP and pCAMBTA3301: at3g51960cDNA were transformed to Arabidopsis by Tumefaciens. The transgenetic homozygous Arabidopsis strains have been derived after screening. Analysis on these strains reveals that strains overexpressing at3g51960 gene have higher level of stress resistance, implying a role of at3g51960 in plant stress regulation.

酵母中发现了bZIP家族的转录因子与酵母的抗氧化性相关，植物中的转录因子at3g51960与酵母中的这一转录因子在空间结构上有很高的同源性，为了验证它在体内的功能，本实验构建了过量表达载体和沉默载体，利用花浸染法把农杆菌携带的双元表达载体，pCAMBTA3301： at3g51960，pCAMBTA3301： at3g51960 Promoter和pCAMBTA3301： at3g51960-GFP及pCAMBTA3301： at3g51960 cDNA转入拟南芥，通过多次筛选已经获得了转基因拟南芥的纯合植株，对获得的转基因植株的表型分析发现，在过量表达at3g51960的转基因拟南芥中对胁迫的抗性有一定程度的变化，因此推测at3g51960可能参与植物的抗性调节。

However, the cytotox-ic dugs cant selectively kill the cancer cells without any side -effects, the decrease of peripheral blood WBC for myleosuppression caused by cytotoxic dugs contribute to the limitation of regular chemotherapy. Evidence was provided that cisplatin and cyclophosphamide used for ovarian cancer caused apoptosis in several in vivo tumors. For the reasons above, in our study, we detected the apoptosis of total peripheral blood WBC in patients with ovarian cancers before and after chemotherapy.
