恶性胶质瘤的有效治疗是生物医学领域的关键性问题。加之，纳米药物如何最有效地穿透血管到达肿瘤部位的问题尚待解决。本项目前期发现纳米药物Basolite F-300@GOD（金属有机骨架材料Basolite F-300与葡萄糖氧化酶GOD的复合纳米药物）递送系统能在肿瘤微环境低pH响应的情况下凋亡血管内皮细胞，从而既有利于改善肿瘤微血管通透性又能抗血管生成。结合前期实验进展，提出了通过饥饿治疗和ROS（活性氧）协同治疗，纳米药物Basolite F-300@GOD@anti-VEGFR2（anti-VEGFR2用于靶向肿瘤微血管内皮细胞）既能凋亡血管内皮细胞，又能凋亡肿瘤的假说。拟用胶质瘤细胞和血管内皮细胞的体外毒性实验和小鼠体内治疗实验结合的方法进行胶质瘤抗血管生成和肿瘤治疗研究，探索凋亡血管内皮细胞与纳米药物递送效率的关系，以改善肿瘤微血管通透性，增强纳米药物治疗效果。

The effective treatment of glioblastoma is a key problem in the field of biomedicine. Moreover, the question of how nano-drug can effectively penetrate blood vessels to reach the tumor site remains to be solved. In the early stage of this project, it was found that the delivery system of nano-drug Basolite F-300@GOD (nanoscaled composite materials of Metal Organic Frameworks Basolite F-300 and Glucose Oxidase) could cause the apoptosis of vascular endothelial cells under the condition of low pH response in the tumor microenvironment, which leads to improving the tumor microvascular permeability and anti-angiogenesis. Combined with the previous experimental progress, a hypothesis was proposed that the nano-drug Basolite F-300@GOD@anti-VEGFR2 (anti-VEGFR2 was used for targeting tumor microvascular endothelial cells ) could both cause the apoptosis of vascular endothelial cells and glioma cells through the synergistic effect of starvation therapy and ROS (Reactive Oxygen Species) therapy. It is proposed to study the anti-angiogenesis and tumor apoptosis of glioma by combining in vitro toxicity experiment and in vivo treatment experiment, and to explore the relationship between the apoptosis of vascular endothelial cells and delivery efficiency of nano-drugs. The aim is to improve the tumor microvascular permeability and enhance the therapeutic effect of nano-drugs.
