The incidence and mortality rate of liver cancer are on the rise worldwide and effective therapeutic strategies are needed. Previous studies demonstrated that exosomes and exosome-like nanoparticles (ELNs) have numerous biological activities including antioxidant, anti-tumor, and anti-inflammatory effects. In this study, ELNs were successfully isolated for the first time from Radix Polygoni Multiflori (RPM) juice by ultracentrifugation. This indicated that RPM-ELNs could be internalized by hepatoma cells effectively and inhibit their proliferation and migration RNA sequencing and qPCR experiments were performed, and the results of bioinformatic analyses revealed that RPM-ELNs could globally regulate expression levels of numerous genes associated with cancer and the cell cycle. In addition, it showed that RPM-ELNs mainly target liver tissue of mice .
全球范围内，肝癌的发病率和死亡率都在上升，因此需要有效的治疗策略。先前的研究表明，外泌体和类外泌体纳米颗粒（ELNs）具有多种生物活性，包括抗氧化、抗肿瘤和抗炎作用。在本研究中，首次通过超速离心从何首乌（RPM）汁中成功分离出ELNs。这表明RPM-ELNs能够有效地被肝癌细胞内化，并抑制其增殖和迁移。进行了RNA测序和qPCR实验，生物信息学分析结果显示，RPM-ELNs可以全面调节与癌症和细胞周期相关的众多基因的表达水平。此外，研究表明RPM-ELNs主要靶向小鼠肝脏组织。
