概括
小分子TEAD抑制剂通过破坏YAP/TAZ-TEAD相互作用,在HPV阴性头支状细胞癌 (HNSCC) 中表现出抗瘤活性. 这种方法针对HNSCC的一个关键漏洞,提供了潜在的新疗法.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 遗传学 遗传学 是一个
背景情况:
- 包括YAP/TAZ-TEAD激活在内的Hippo路径变化在HPV阴性头支状细胞癌 (HNSCC) 中很常见.
- 像FAT1突变和YAP1/WWTR1放大等遗传变化表明HNSCC依赖于YAP/TAZ-TEAD转录程序.
- 小分子TEAD抑制剂 (smTEADi) 为准Hippo路径失调提供了一个新的治疗策略.
研究的目的:
- 研究smTEADi,特别是SW-682在HPV阴性HNSCC中的临床前抗瘤活性.
- 探索针对这种癌症类型中YAP/TAZ-TEAD轴的治疗潜力.
主要方法:
- 利用了siRNA敲除,一种遗传编码的TEAD抑制剂 (pTEADi),以及新的smTEADi SW-682.
- 采用了互补的实验方法来破坏YAP/TAZ-TEAD的相互作用.
- 进行RNA测序 (RNA-seq) 来定义TEADi目标基因.
主要成果:
- 破坏YAP/TAZ-TEAD相互作用抑制了目标基因转录和HNSCC瘤生长.
- 具有FAT1变化的细胞对TEAD抑制剂的敏感性增加.

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.

Tumor Immunotherapy
468
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Cell-surface Signaling
51.4K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.
