概括
一种新型药物输送系统通过向瘤微环境来增强多克索鲁比辛 (DOX) 对形甲状腺癌 (ATC) 的疗效. 这种系统增加了瘤部位的DOX度,改善了治疗结果并减少了心脏毒性.
科学领域:
- 在瘤学瘤学.
- 纳米技术纳米技术
- 药物输送系统 药物输送系统
背景情况:
- 无塑性甲状腺癌 (ATC) 是具有高死亡率的侵袭性,当前的治疗方法,如多克索鲁比 (DOX) 有局限性.
- 由于瘤度不足和严重的心脏毒性阻碍了DOX的有效性,因此需要改进输送方法.
- 瘤微环境的特征为开发先进的药物输送系统 (DDS) 提供了潜在的目标.
研究的目的:
- 开发一种对刺激有反应的DDS,以提高ATC中的DOX疗效.
- 创建一个专门针对ATC瘤微环境的载体.
- 为了提高DOX在ATC处理中的安全性.
主要方法:
- 构建了一个对肝酶 (HPSE) 响应的自组装载体,TET-HS-NI,用TET修改为αvβ3向.
- 将DOX装载到载体中,以创建TET-HS-NI/DOX.
- 在斑马鱼CDX和ATC正位模型中评估了TET-HS-NI/DOX的疗效和安全性.
主要成果:
- 发现HPSE在ATC瘤微环境中表达高,但在正常甲状腺组织中表达不高.
- 与单独使用DOX相比,TET-HS-NI/DOX系统显示出增强的抗瘤疗效.
- 开发的DDS在临床前模型中显著提高了DOX的安全性.
结论:
- 一个新的HPSE响应药物递送系统 (TET-HS-NI/DOX) 已成功开发用于ATC治疗.
- 该系统在HPSE过度表达的ATC微环境中选择性地释放DOX,增加了局部药物度.
- 这些发现表明,有希望的新治疗策略可以改善ATC治疗结果和患者安全.

Targeted Cancer Therapies
8.6K
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.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
588
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...
