The key role of the NFL-TBS.40-63 peptide (BIOT-NFL) is to target and destroy glioma cancer cells. Recently we have performed a novel peptide-hybrid-gold nanovector (BIOT-NFL-PEG-AuNPs) capable to destroy microtubule network of pancreatic cancer cells (PDAC) exhibiting a decrease of tumor index with a real anti-angiogenic effect. In order to improve the scientific background of our study, we conceived a chemotherapeutic hybrid nanovector based on gold-doxorubicin (DOX) functionalized with the NFL-TBS.40-63 peptide (BIOT-NFL) as a promising therapeutic in PDAC cancer. Mouse transplantation tumor model induced by PANC-1/ADR human pancreatic cancer resistant strain cells, was used to evaluated the therapeutic efficacy of DOX IN-NFL@AuNPs as chemotherapeutic nano-drug. Our results indicate that DOX IN-NFL@AuNPs have a great impact on the decrease of the tumor growth and decreased the tumor index with a relevant effect on cytokines and ROS levels, thus confirming the impact of DOX IN-NFL@AuNPs to boost the immune system.
NFL-TBS.40-63肽(BIOT-NFL)的关键作用是靶向并摧毁神经胶质瘤癌细胞。最近,我们制备了一种新型的肽-杂化-金纳米载体(BIOT-NFL-PEG-AuNPs),它能够破坏胰腺癌细胞(PDAC)的微管网络,使肿瘤指数降低,并具有真正的抗血管生成作用。为了提升我们研究的科学背景,我们构思了一种基于用NFL-TBS.40-63肽(BIOT-NFL)功能化的金-阿霉素(DOX)的化疗杂化纳米载体,作为一种有前景的PDAC癌症治疗药物。利用PANC-1/ADR人胰腺癌细胞耐药株诱导的小鼠移植瘤模型,来评估DOX IN-NFL@AuNPs作为化疗纳米药物的治疗效果。我们的结果表明,DOX IN-NFL@AuNPs对肿瘤生长的抑制有很大影响,降低了肿瘤指数,对细胞因子和活性氧水平有显著影响,从而证实了DOX IN-NFL@AuNPs对增强免疫系统的作用。
