摘要:


文题释义:

趋化因子受体4:是一种具有7次跨膜结构的G蛋白偶联受体,与癌症微环境的纤维化和免疫抑制等方面有关。肿瘤微环境内的基质细胞衍生因子1与其结合后,通常促进肿瘤细胞的生存增殖以及肿瘤血管的生成,它们还招募免疫细胞并引导它们做出特定的免疫抑制反应。
程序性细胞死亡受体:是位于T细胞表面的抑制性受体,与其配体1结合后可以抑制T细胞的活化,减少抗肿瘤细胞因子的产生,降低杀伤活性,从而使免疫系统沉默。


背景:免疫治疗可通过多种途径增强抗肿瘤免疫反应,联合免疫治疗是一个更好的选择。超声靶向微泡破坏技术可将药物、基因、抗体和细胞因子直接输送到免疫细胞的细胞质中,进一步增强免疫应答。然而,通过超声靶向微泡破坏技术将携趋化因子受体4抗体和细胞程序性死亡配体1抗体双靶向纳米微泡应用于卵巢癌的治疗尚未见报道。

目的:探讨超声辐照携趋化因子受体4抗体和程序性死亡配体1抗体双靶向纳米微泡对卵巢癌细胞增殖、迁移的影响。
方法:对IOSE-80正常卵巢上皮细胞及SKOV3、CAOV3卵巢癌细胞进行培养及扩增,采用双标记荧光免疫法对3种细胞中的趋化因子受体4和细胞程序性死亡配体1蛋白进行共定位,蛋白质印迹法检测3种细胞中趋化因子受体4和程序性死亡配体1蛋白相对表达量,并筛选出实验细胞。制备携不同配体的靶向纳米微泡后,即单纯的纳米微泡、携趋化因子受体4抗体的纳米微泡、携趋化因子受体4和程序性死亡配体1抗体的纳米微泡。取对数生长期的SKOV3卵巢癌细胞,分6组处理:A组加入McCoy’s 5A培养基,B组加入含基质细胞衍生因子1的McCoy’s 5A培养基,C组加入单纯的纳米微泡溶液与含基质细胞衍生因子1的McCoy’s 5A培养基,D组加入携趋化因子受体4抗体的纳米微泡溶液与含基质细胞衍生因子1的McCoy’s 5A培养基,E组加入携趋化因子受体4和程序性死亡配体1抗体的纳米微泡溶液与含基质细胞衍生因子1的McCoy’s 5A培养基,F组加入单纯的纳米微泡溶液,超声辐照120 s,孵育48 h后,采用CCK-8法检测细胞存活率,通过伤口愈合实验检测B-E组细胞的愈合迁移能力。

结果与结论:①免疫荧光染色显示,3种细胞均可表达趋化因子受体4和程序性死亡配体1蛋白;蛋白质印迹法检测显示,SKOV3、CAOV3卵巢癌细胞中的趋化因子受体4和程序性死亡配体1蛋白表达量均高于IOSE-80正常卵巢上皮细胞(P < 0.05);②CCK-8检测结果显示,B组细胞存活率高于A组(P < 0.05),F组细胞存活率低于A组(P < 0.05),B-E组细胞存活率逐渐降低,组间两两比较差异有显著性意义(P < 0.05);③伤口愈合实验显示,B-E组细胞愈合率逐渐降低,组间两两比较差异有显著性意义(P < 0.05);④结果表明,超声靶向微泡破坏技术联合携趋化因子受体4抗体和程序性死亡配体1抗体双靶向纳米微泡可显著抑制卵巢癌细胞的增殖迁移。

Abstract: BACKGROUND: Immunotherapy enhances the anti-cancer immune response in many ways, so combined immunotherapy is a better choice. Ultrasound-targeted microbubble destruction technique delivers drugs, genes, antibodies and cytokines directly to the cytoplasm of immune cells and enhances the immune response. However, the application of ultrasound-targeted microbubble destruction technique in the treatment of ovarian cancer with both CXC chemokine receptor 4 antibody and programmed death-ligand 1 antibody has not been reported.
OBJECTIVE: To investigate the effect of ultrasound irradiation on the proliferation and migration of ovarian cancer cells with CXC chemokine receptor 4 antibody and programmed death-ligand 1 antibody double targeted nanobubbles.
METHODS: IOSE-80 normal ovarian epithelial cells, SKOV3 and CAOV3 ovarian cancer cells were cultured and expanded. Double labeling fluorescence immunoassay was used to co-locate CXC chemokine receptor 4 and programmed death-ligand 1 protein. Western blot assay was used to detect the relative expression of CXC chemokine receptor 4 and programmed death-ligand 1 protein in three kinds of cells and screen out the experimental cells, i.e., pure nanobubbles, nanobubbles carrying CXC chemokine receptor 4 antibody, nanobubbles carrying CXC chemokine receptor 4 and programmed death-ligand 1 antibody. SKOV3 ovarian cancer cells in the logarithmic growth phase were taken and divided into six groups for treatment. Group A was added with McCoy's 5A medium. Group B was added with McCoy's 5A medium containing stromal cell-derived factor-1. Group C was added with pure nanobubble solution and McCoy's 5A medium containing stromal cell-derived factor-1. Group D was added with nanobubble solution containing CXC chemokine receptor 4 antibody and McCoy's 5A medium containing stromal cell-derived factor-1. Group E was added with nanobubble solution containing CXC chemokine receptor 4 and programmed death-ligand 1 antibody and McCoy's 5A medium containing stromal cell-derived factor-1. Pure nanobubble solution was added in group F. After ultrasonic irradiation for 120 seconds and incubation for 48 hours, the survival rate of cells was measured by CCK-8 assay, and the healing and migration ability of cells in groups B-E were measured by wound healing test.
RESULTS AND CONCLUSION: (1) Immunofluorescence staining showed that CXC chemokine receptor 4 and programmed death-ligand 1 protein could be expressed in all three kinds of cells. Western blot assay showed that the expression levels of CXC chemokine receptor 4 and programmed death-ligand 1 in SKOV3 and CAOV3 ovarian cancer cells were significantly higher than those in IOSE-80 normal ovarian epithelial cells (P < 0.05). (2) CCK-8 assay results exhibited that the cell survival rate of group B was higher than that of group A (P < 0.05). The cell survival rate of group F was lower than that of group A (P < 0.05). The cell survival rate of groups B-E decreased gradually, and there were significant differences between the two groups (P < 0.05). (3) Wound healing test demonstrated that the cell healing rate of groups B-E decreased gradually, and there were significant differences between the two groups (P < 0.05). (4) The results show that the use of CXC chemokine receptor 4 antibody and programmed death-ligand 1 antibody double targeted nanobubbles under ultrasound-targeted microbubble destruction can significantly inhibit the proliferation and migration of ovarian cancer cells.
