概括

一种新型的纳米原药联合提供多种药物,以向三阴性乳腺癌干细胞 (TNBCSCs) 和瘤. 这一策略克服了化学抵抗,并抑制了转移,从而改善了TNBC治疗.

科学领域:

生物医学工程生物医学工程
纳米技术纳米技术
在瘤学瘤学.

背景情况:

三阴性乳腺癌 (TNBC) 是具有侵略性的,由抗化疗的干细胞 (TNBCSCs) 驱动.
TNBCSCs导致瘤转移和复发,这构成了重大的临床挑战.
目前的治疗方法无法消除静止的TNBCSCs,需要新的治疗策略.

研究的目的:

开发一种二硫化物介导的自组装纳米前药物,用于同时治疗TNBC和TNBCSC.
调查铁灭症诱导剂,分化剂和化疗剂的同时递送.
克服化学抵抗并抑制TNBC中的转移.

主要方法:

使用二硫化物键进行自我组装和GSH响应释放的纳米原药的制造.
铁灭药物,差异化剂和化疗剂的同时使用.
在TNBC小鼠模型中评估抗瘤疗效和转移抑制.

主要成果:

这种纳米前药物证明了多种治疗剂的有效联合递送和受控释放.
分化剂转化TNBCSCs,而铁和化疗诱导细胞死亡.
在体内观察到抗瘤功效的显著改善和瘤转移的抑制.

结论:

开发的纳米原药为根除TNBCSC和治疗TNBC提供了一个有希望的全合一战略.
这种方法增强了化疗的敏感性,并减少了与茎状相关的耐药性.
该策略有可能通过向癌细胞和干细胞来改善TNBC患者的治疗结果.

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Targeted Cancer Therapies

Targeted Cancer Therapies

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.
There are several types of targeted therapies against...
