项目摘要
To develop an effective anticancer drug, the understanding of cancer mechanisms and drug delivery system (DDS) is very important. Here, we have developed a method for in vivo imaging with very high spatial accuracy and succeeded in tracking the membrane protein PAR1 during metastasis in living mice. To investigate drug movement in association to its size in tumor, fluorescent nano-particles were injected into the tumor-bearing mice and visualized by in vivo imaging. Additionally, we developed a novel method to evaluate the structural stability and anti-cancer effect of drug-incorporating polymeric micelles.
为了开发有效的抗癌药物,了解癌症机制和药物输送系统(DDS)非常重要。在这里,我们开发了一种具有非常高空间精度的体内成像方法,并成功追踪活体小鼠转移过程中的膜蛋白 PAR1。为了研究药物运动与其在肿瘤中大小的关系,将荧光纳米颗粒注射到荷瘤小鼠体内,并通过体内成像进行可视化。此外,我们开发了一种新方法来评估掺入药物的聚合物胶束的结构稳定性和抗癌效果。
