Targeted Cancer Therapies

7.8K
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...

科学领域:

  • 癌症学
  • 分子生物学
  • 基因组学

背景情况:

  • 在失去雄激素受体 (AR) 依赖后,抗化前列腺癌 (CRPC) 呈现出具有侵略性的瘤.
  • 了解CRPC的分子异质性对于开发有效疗法至关重要.

研究的目的:

  • 在AR依赖和神经内分泌类型之外分类CRPC亚型.
  • 确定新型治疗点并指导CRPC的治疗策略.

主要方法:

  • 使用ATAC-seq,RNA-seq和DNA测序对器官,患者衍生的异种移植和细胞系.
  • 应用了转录学签名来对366名CRPC患者进行分类.

主要成果:

  • 确定了两种新的AR阴性/低亚型:Wnt依赖性和干细胞类 (SCL).
  • 由激活蛋白-1 (AP-1) 转录因子驱动的SCL亚型是第二个最普遍的CRPC亚型.
  • 发现AP-1与YAP/TAZ和TEAD蛋白质的相互作用维持了SCL亚型特异性的染色体可访问性和转录形状.

结论:

  • 对CRPC的分子分类显示出不同的亚型,包括SCL组.
  • 这些发现突出了AP-1,YAP/TAZ和TEAD作为SCLCRPC的潜在治疗点.
  • 这种分类可以为CRPC患者提供个性化治疗决策.
