概括
在PEG-PLGA纳米载体 (NPBer) 中封装的柏柏林 (Ber) 增强结直肠癌 (CRC) 细胞亡并抑制瘤生长. 这种纳米药物输送系统改善了Ber.
科学领域:
- 在瘤学瘤学.
- 纳米技术 纳米技术
- 药理学 药理学是指药理学的学科.
背景情况:
- 大肠直肠癌 (CRC) 是全球领先的癌症,结果不佳.
- 柏柏林 (Ber) 是一种天然化合物,具有抗CRC的潜力,但其生物可用性较差.
- 纳米药物输送系统在药物保护,生物可用性和降低毒性方面具有优势.
研究的目的:
- 开发和评估Berberine装载的PEG-PLGA纳米载体 (NPBer),用于增强结直肠癌治疗.
- 与自由柏柏林相比,研究NPBer的体外和体内抗癌机制.
主要方法:
- 纳米沉被用于将柏柏林封装到PEG-PLGA纳米载体中,形成NPBer.
- 在体外研究中使用流细胞计和CCK8试验来评估HCT116CRC细胞中的NPBer吸收和细胞毒性.
- RNA测序 (RNA-Seq) 分析了由Free Ber和NPBer治疗诱导的转录基因变化.
- 在体内研究评估了NPBer的瘤向,积累和抗增殖作用.
主要成果:
- 与自由相比,NPBer表现出增强的细胞吸收和更强的抑制HCT116CRC细胞增殖.
- RNA-Seq显示,Free Ber诱导了细胞衰老,铁亡,亡,并调节了关键的CRC信号通路 (Wnt,TGF-β,Hippo,mTOR).
- 在体内,NPBer显著改善了药物递送,通过线粒体自增强了细胞亡,并抑制了Notch信号传递.
- 在体内,NPBer表现出优异的瘤积累,持续的药物向,诱导最大的亡,并有效地抑制了HCT116瘤的生长.
结论:
- PEG-PLGA纳米载体封装增强了Berberine对结直肠癌的抗癌疗效.
- 通过改善药物输送和增强抗瘤机制,NPBer代表了结直肠癌的有希望的治疗策略.

Targeted Cancer Therapies
7.5K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Drugs that Stabilize Microtubules
2.0K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
