Anticancer Drug Resistance of HeLa Cells Transfected With Rat Glutathione S-transferase pi Gene

Objective To establish a cytologic expressing system of rat glutathione S-transferase pi (GST-pi) cDNA for detecting the resistance of HeLa cells to anticancer drugs. Methods The assessment was made with various anticancer drugs (adriamycin, mitomycin, cisplatinum and vincristine) that showed different cytotoxicities in transfectant HeLa cells with pSV-GT containing rat GST-pi cDNA (HeLa/pSV-GT) or control pSV-neo (HeLa/pSV-neo). Expression levels of GST-pi mRNA in HeLa/pSV-GT and HeLa/pSV-neo were measured by in situ hybridization using Digoxin-labelled cDNA probe. Results HeLa/pSV-GT expressed significantly high degree of GST-pi mRNA, whereas both HeLa/pSV-neo and HeLa cells had very low expression. Cytotoxicities of HeLa/pSV-GT and HeLa/pSV-neo with 4 anticancer drugs were measured by MTT assay. Drug concentrations for yielding 50% inhibition (IC50) in HeLa/pSV-GT by adriamycin, mitomycin and cisplatinum were 70.13μg/mL, 10.95μg/mL and 16.52μg/mE respectively. In contrast, IC50 in HeLa/pSV-neo was 10.34μg/mL, 7.48μg/mL and 13.70μg/mE respectively. The cytotoxicities of vincristine on both HeLa/pSV-GT and HeLa/pSV-neo were not significantly different. Conclusions Our findings suggest that HeLa/pSV-GT containing rat GST-pi cDNA is resistant to some anticancer drugs due to overexpression of GST-pi. Also, HeLa/pSV-GT cell line could serve as a useful cytogenetic model for further research.

引流淋巴结树突状细胞对自身肿瘤细胞作用研究

目的　从胃癌患者引流淋巴结中分离和定向诱导培养扩增树突状细胞 (DC) ,观察其经自身肿瘤细胞抗原冲击后对自身细胞因子诱导的杀伤细胞 (CIK细胞 )杀伤活性的影响。方法　取手术切除肿瘤周围转移引流淋巴结 ,提取单个核细胞 ,将贴壁生长的细胞用细胞因子rhGM CSF、rhIL 4、rhTNF α联合诱导培养DC ,然后用自身肿瘤细胞抗原冲击DC并作用CIK细胞 ,最后检测CIK细胞杀伤三种靶细胞 (自身胃癌细胞、K5 6 2和SGC 790 1细胞 )的活性。结果　胃癌患者转移引流淋巴结中的贴壁细胞 ,经细胞因子联合诱导培养 ,DC含量可达 4 5 %。经自身肿瘤抗原冲击的引流淋巴结DC活化的CIK细胞 ,杀伤自身肿瘤细胞活性达 79 3% ,单纯CIK细胞为 33% ,两者比较差异有显著意义 (P <0 0 1) ;而对K5 6 2和SGC 790 1细胞杀伤活性无明显差异。结论　肿瘤周围转移引流淋巴结贴壁细胞在体外能定向诱导扩增出大量DC :DC经自身肿瘤抗原冲击后能明显提高CIK细胞对自身肿瘤细胞的杀伤活性。此结果为肿瘤DC的免疫治疗应用奠定了理论基础

Study on mechanism of huanshao dan in brain protectionΔin brain protectionΔ

Objective: To observe the behavioral and biochemical effects of a traditional Chinese medicine Huanshao Dan (HSD) on learning and memory deficits in transient cerebral ischemia model in mice.Methods: Step-through experiments, receptor binding test and choline acetyltransferase (ChAT) activities determination were performed.Results: Mice undertaken transient ischemia commited much more mistakes in step-through experiments and showed relatively higher³ H-MK801 binding in cerebral cortex and hippocampus than in sham operated animals. HSD decoction was most effective in reducing these mistakes in mice. At the same time, and³ H-MK801 binding of cerebral cortex and hippocampus tissues were also significantly decreased, while ChAT activities in the same tissues were increased.Conclusion: HSD might antagonize ischemic injury of brain through inhibition of glutamate N-methyl-D-Aspartic acid receptor overactivity.
