Abstract

Due to the rapid growth of a tumor, the tumor cell metabolism becomes more active, resulting in the overexpression of albumin-binding proteins for transporting albumin as an energy and amino source. In that case, making use of nutrient transporters for targeted drug delivery to the brain becomes attractive. Herein, we synthesized albumin nanoparticles by a desolvation process, modified them with folic acid to enhance blood-brain-barrier (BBB) penetration and cellular uptake, and then loaded them with the antitumor drug paclitaxel (PTX) and autophagy inhibitor chloroquine (CQ) for combination therapy. The albumin nanoparticles could cross the BBB and target glioma cells effectively, and the combination therapy of PTX and CQ induced more cell apoptosis than PTX treatment alone in vitro. The results of the role of autophagy in the sensitivity of chemotherapeutic PTX to glioma cells showed that the stemness-associating genes (SOX2, POU5F1 and NANOG) of live glioma cells increased in the presence of PTX, while they dropped sharply with the combination including CQ. More importantly, it was found that the combined delivery system FA-BSA-NP exhibited the most effective cell apoptosis. Our findings demonstrated that drug-loaded albumin nanoparticles could facilitate a combination of chemotherapy and autophagy inhibition for effective glioma therapy.

摘要

由于肿瘤的快速生长,肿瘤细胞代谢变得更加活跃,导致白蛋白结合蛋白过表达,将白蛋白作为能量和氨基酸的来源进行转运。在这种情况下,利用营养转运蛋白将靶向药物递送到大脑变得具有吸引力。本文通过去溶剂化过程合成白蛋白纳米粒,用叶酸对其进行修饰,以增强血脑屏障(BBB)穿透和细胞摄取能力,然后装载抗肿瘤药物紫杉醇(PTX)和自噬抑制剂氯喹(CQ)进行联合治疗。白蛋白纳米粒可以穿过血脑屏障并有效靶向神经胶质瘤细胞,并且体外联合治疗 PTX 和 CQ 诱导的细胞凋亡比单独使用 PTX 治疗诱导的细胞凋亡更多。自噬在化疗药物 PTX 对神经胶质瘤细胞敏感性中的作用的结果表明,存在 PTX 时,活神经胶质瘤细胞的干性相关基因(SOX2、POU5F1 和 NANOG)增加,而与 CQ 联合使用时,这些基因急剧下降。更重要的是,发现载药白蛋白纳米粒的联合递送系统 FA-BSA-NP 表现出最有效的细胞凋亡。我们的研究结果表明,载药白蛋白纳米粒可以促进化疗和自噬抑制的联合治疗,从而有效治疗神经胶质瘤。
