    • 摘要: 目的:观察miR-126在不同转移潜能的人结肠癌细胞系中的表达情况及其对结肠癌细胞增殖、侵袭转移能力的影响并探讨可能的作用机制.方法:采用实时荧光定量PCR检测结肠癌细胞系(SW480、SW620及HCT116)中miR-126的表达量.通过脂质体瞬时转染法将miR-126过表达(miR-126 mimics),并设置阴性对照组,然后采用CCK8法检测细胞的增殖能力,细胞划痕实验检测细胞的迁移能力,Transwell侵袭小室实验检测细胞的侵袭能力,Western blot实验检测E-cadherin和Vimentin蛋白表达量的变化.结果:相对于低转移潜能的结肠癌细胞株SW480,miR-126在高转移潜能的SW620和HCT116细胞中的表达降低.过表达miR-126可使SW620细胞增殖、迁移和侵袭能力降低,E-cadherin蛋白表达增加,Vimentin蛋白表达降低,差异具有统计学意义(P<0.05).结论:低表达的miR-126与结肠癌的转移密切相关,miR-126影响结肠癌细胞生物学行为的作用可能是通过调控EMT进程实现的.%Objective:To investigate the expression of miR-126 in human colon cancer cell lines with different metastatic potential and its effect on the proliferation, invasion and metastasis of colon cancer cells, and to explore the possible mechanism.Methods:The expression of miR-126 in human colon cancer cell lines(SW480,SW620 and HCT116) was determined by Real-time fluorescence quantitative PCR.miR-126 mimics were transiently overexpressed in SW620 cells throuIgh liposome transfection and the negative control group was set up.The proliferation ability of cells was detected by CCK8 method and the mobility of cells was detected by wound healing assay and Transwell migration and invasion assay.The expression of E-cadherin,Vimentin was determined by Western blot.Results:The expression of miR-126 was decreased in SW620 and HCT116 cells with high metastatic potential compared SW480 cells with low metastatic potential.The overexpression of miR-126 significantly inhibited the proliferation,migration and invasion ability of SW620 cells and Western blot indicated that miR-126 overexpression increased the expression of E-cadherin and decreased the expression of Vimentin in SW620 cells,which was significantly different from that of negative control(P<0.05).Conclusion:Low expression of miR-126 is closely related to metastasis of colon cancer and the effect of miR-126 on the biological behavior of colon cancer cells may be mediated by the regulation of the EMT process.

    • 摘要: 目的:利用含有CEA625-667基因的单倍体疫苗pcDNA-CEA625-667及三串联体的DNA疫苗pcDNA-triCEA625-667免疫小鼠后,观察其诱导的抗肿瘤免疫效应.方法:采用4~6周纯系BALB/c小鼠,肌肉注射法分pc-DNA3.0、pcDNA-CEA625-667、pcDNA-triCEA625-667三组免疫小鼠,对其激发的机体特异性及非特异性免疫反应进行研究.流式细胞术检测免疫小鼠脾细胞的T细胞亚群和CD4+/CD8+比值;3 H-TdR掺入法检测免疫小鼠的特异性淋巴细胞增殖;Western blot杂交及ELISA法检测免疫小鼠血清中的CEA特异性抗体;ELISA法检测免疫动物脾细胞体外诱导IFN-γ、IL-4、GM-CSF的分泌水平.结果:实验组与对照组的CD4+/CD8+比值差异无统计学意义;经过基因疫苗免疫的小鼠与天然小鼠相比,其脾细胞在体外与短肽共孵育之后,会在更短的时间内出现更明显的细胞增殖;免疫了CEA迷你基因串联体肿瘤疫苗的小鼠血清中可以产生低滴度的抗体,提示HTL的活化;免疫小鼠脾细胞上清中IFN-γ的含量明显高于对照组,而pc-DNA3.0,pcDNA-CEA625-667,pcDNA-tri-CEA625-667各组IL-4的含量均很低,差异无统计学意义;迷你基因三倍体疫苗所引发的增殖效应以及释放细胞因子的水平均高于迷你基因一倍体,说明我们所采用将目的基因多倍串联的抗原改造的方式起到了增强免疫效应的作用.结论:CEA迷你肽表位基因单倍体及三倍体疫苗均不能显著改变动物体内CD4/CD8比值,但均能诱导HTL活化,使被免疫机体T细胞趋向于Th1效应且三倍体疫苗的免疫原性强于单倍体疫苗.%Objective:To observe the immunological activity of haploid vaccine and three tandem repeats of minigene DNA vac -cine derived from Carcinoembryonic Antigen (CEA) gene.Methods:The immunoreaction was induced by intramuscular injection with pc-DNA3.0,pcDNA-CEA625-667 and pcDNA-triCEA625-667 in BALB/c.Four weeks after injection,the spleen cells and serum were separa-ted respectively from the mice for the in vitro assessment .Changes of the T lymphocytes subset was analyzed by flow cytometry .Lymph proliferation responses were tested by 3 H-TdR incorporation ,IFN-γ,IL-4 and GM-CSF in their cultural supernatants were detected with ELISA and seral IgG antibody against CEA were detected with Western blot and ELISA .Results:The difference of the ratio of CD 4+/CD8+of the mice immuned by pc-DNA3.0,pcDNA-CEA625-667 or pcDNA-triCEA625-667 was not significant.Lymph proliferation responses were more significant in the mice immuned by pcDNA-CEA625-667 and pcDNA-triCEA625-667 in a shorter time by contrast with na ?ve mice.Low tilter IgG antibody against CEA was detected in the antiserum of the mice immuned by repeats of minigene DNA vaccine , which suggested the activation of helper T-cell.ELISA showed that the level of IFNγin the 3 days culture of the splenocytes was rela-tively higher in the groups of minigene DNA vaccination than in the control groups ,while IL-4 expression was absent in all groups .The immune response level elicited by three tandem repeats of minigene DNA vaccine pcDNA -triCEA625-667 was superior to that elicited by pcDNA-CEA625-667 ,which showed that any immunogenic inadequacies in minigene presentation can be rectified by linking itself in a string-of-beads vaccine.Conclusion:The haploid vaccine and three tandem repeats of minigene DNA vaccine derived from CEA geneboth can not change the ratio of CD 4+/CD8+but can induce the activation of helper T-cell and skew T -cells toward Th -1 response.The immune response level elicited by three tandem repeats of minigene DNA vaccine was superior to thatelicited by haploid vaccine .

    • 摘要: Objective Effect of large system (50 mL) cryopreservation on immunophenotype and killing activities of cytokine induced killer (CIK) cells.Methods Peripheral blood samples were collected from 6 healthy volunteers and then the mononuclearcell were isolated by Ficoll method and were induced to CIK cells.The CIK cells were reanimated at 1 month after cryopreservation and collected.The cell survival rate and immunophenotype was detected by flow cytometry before and after cryopreservation.The killing activity of CIK cells was detected by culturing with breast cancer cells (target ratio 10 ∶ 1 and 40 ∶ 1) and compared with fresh cell;and the killing activity of CIK cells under different target ratio was compared between before and after cryopreservation.Results The average cell survival rate of CIK cells before cryopreservation was (97.79 ± 1.92) %,which was significantly higher than that after reanimation(83.61 ± 3.42) % (P < 0.05).The proportion of CIK with CD3 +,CD3 + CD4 +,CD3 + CD8 +,CD3 + CD56 + phenotype after reanimation was slightly lower than that before cryopreservation,but the difference was not statistically significant(P > 0.05).There was no significant difference in the cell killing rate of CIK cells before cryopreservation and after reanimation when the target ratio was 10 ∶ 1 and 40 ∶ 1 (P >0.05);the cell killing rates of CIK cells before cryopreservation and after reanimation when the target ratio was 40 ∶ 1 were significantly higher than those when the target ratio was 10 ∶ 1 (P < 0.05).Conclusion The large system (50 mL) cryopreservation can effect the survival rate of CIK cells,but has no effect on the immune phenotype and cell activity.%目的 探讨大体系(50 mL)冻存对细胞因子诱导的杀伤(CIK)细胞免疫表型及细胞杀伤活性的影响.方法 采集6例健康志愿者的外周血,采用Ficoll法分离得到单个核细胞,用细胞因子诱导培养CIK细胞.收集冻存1个月后复苏的CIK细胞,采用流式细胞术检测其冻存前后的细胞活率和免疫表型;通过与乳腺癌细胞共培养(效靶比10∶1和40∶1)的方法测定其杀伤活性,与新鲜未冻存的细胞杀伤活性进行比较,同时并对不同效靶比冻存前后的细胞杀伤活性进行比较.结果 CIK细胞大体系冻存前平均细胞活率(97.79 ± 1.92)%,显著高于复苏后的(83.61±3.42)%(P<0.05).复苏后CIK细胞中CD3+、CD3+ CD4+、CD3+ CD8+、CD3+ CD56+表型CIK细胞所占比例虽较冻存前稍有降低,但差异均无统计学意义(P>0.05).效靶比10∶1、40∶1时冻存前细胞和复苏后细胞杀伤率比较差异均无统计学意义(P>0.05);效靶比40∶1时冻存前细胞和复苏后细胞杀伤率均显著高于效靶比10∶1时(P<0.05).结论 大体系(50 mL)冻存对于CIK细胞活率虽有影响,但对免疫表型和细胞活性均未影响.
