Abstract

This study tried to develop the α-Hederin/Oxaliplatin (OXA) dual-loaded rHDL (α-Hederin-OXA-rHDL) modified liposomes to improve the therapeutic index on colon adenocarcinoma (COAD). The α-Hederin-OXA-rHDL were prepared and evaluated for characterizations, accumulate to tumor tissues, and antitumor activity. A thorough investigation into oxaliplatin resistant and KRAS-mutant related hub keg genes were identified and performed to assess the prognosis role of the genetic signature in COAD. The potential immune signatures and molecular docking for verifing the predicted targets of α-Hederin-OXA-rHDL in tumor-bearing mice. Results suggested that α-Hederin-OXA-rHDL could enhance the sensitivity of oxaliplatin in HCT116/L-OHP cells via the regulation of KEAP1/NRF2 -mediated signaling and HO1 or GPX4 proteins. Furthermore, α-Hederin-OXA-rHDL regulated the predicted targets of PRDM1 interaction with miR-140-5p, efficient activing CD8 T cell to improve therapeutic response in vivo. Collectively, this work provides drug delivery with rHDL dual-loaded α-Hederin and oxaliplatin synergistically targets cancer cells and effectory T cells combating COAD.

摘要

本研究试图开发负载α-常春藤皂苷/奥沙利铂(OXA)的重组高密度脂蛋白(α-常春藤皂苷-OXA-rHDL)修饰脂质体,以提高对结肠腺癌(COAD)的治疗指数。制备了α-常春藤皂苷-OXA-rHDL并对其进行表征、肿瘤组织蓄积和抗肿瘤活性评估。对奥沙利铂耐药和KRAS突变相关的核心基因进行了全面研究,以评估该基因特征在COAD中的预后作用。在荷瘤小鼠中进行了潜在免疫特征分析和分子对接,以验证α-常春藤皂苷-OXA-rHDL的预测靶点。结果表明,α-常春藤皂苷-OXA-rHDL可通过调节KEAP1/NRF2介导的信号通路以及HO1或GPX4蛋白,增强奥沙利铂对HCT116/L-OHP细胞的敏感性。此外,α-常春藤皂苷-OXA-rHDL调节PRDM1与miR-140-5p相互作用的预测靶点,有效激活CD8 T细胞,以改善体内治疗反应。总的来说,这项工作提供了一种药物递送方法,负载α-常春藤皂苷和奥沙利铂的rHDL协同靶向癌细胞和效应T细胞,对抗COAD。
