项目摘要
Anti-HER2 antibody can induce antitumor responses, and can be used in delivering drugs to HER2-overexressing cancer.We produced in this study a heat induction procedure which provides hyperthermia using MgFe2O4 nanoparticles that generate heat in an alternating magnetic field. In addition, we constructed anti-HER2 immunoliposomes containing MgFe2O4 nanoparticles, which act as tumor-targeting vehicles, combining anti-HER2 antibody therapy with hyperthermia. The magnetite nanoparticle-loaded anti-HER2 immunoliposomes exerted HER2-mediated antiproliferative effects on SKBr3 breast cancer cells in vitro. Moreover, 60% of magnetite nanoparticles were incorporated into SKBr3, and the cells were then heated at 50℃ under an alternating magnetic field, resulting in strong cytotoxic effects. These results suggest that this novel therapeutic tool is applicable to treatment of HER2-overexpressing cancer. Intravenous administration was not feasible in this series of study. For the next series of study, we plan to research an in vivo model, which comprise an intravenous injection of MgFe2O4 liposome and superselective binding to the SKBr3 cells.
抗HER2抗体可以诱导抗肿瘤反应,并可用于向HER2过高的癌症患者输送药物。在本研究中,我们生产了一种热诱导程序,使用在交变磁场中产生热量的MgFe2O4纳米粒子进行热疗。此外,我们构建了含有纳米镁铁氧体的抗HER2免疫脂质体,将其作为肿瘤靶向载体,将抗HER2抗体治疗与热疗相结合。磁性纳米颗粒负载的抗HER2免疫脂质体在体外对SKBr3乳腺癌细胞具有HER2介导的抗增殖作用。此外,将60%的磁性纳米颗粒掺入到SKBr3中,然后在50℃的交变磁场下对细胞进行加热,产生了强烈的细胞毒效应。这些结果表明,这种新的治疗工具适用于HER2过表达肿瘤的治疗。在这一系列研究中,静脉给药是不可行的。在接下来的一系列研究中,我们计划研究体内模型,包括静脉注射镁铁氧体脂质体和超选择性结合到SKBr3细胞。
