背景情况:
- 卵巢癌 (OCS) 是一种罕见的,激进的妇科恶性瘤,对标准基化疗反应不佳.
- 在OCS瘤中,介酶体标志物如N-MYC和HMGA2.2的表达高.
- 埃里布林是一种微管向剂,在OCS模型中显示出降低这些标记物的潜力,并逆转上皮质到介质细胞转变 (EMT).
研究的目的:

- 评估埃里布林和西斯普拉丁在联合治疗中的疗效.
- 在临床前OCS模型中验证有前途的组合.
主要方法:
- 使用西斯和埃里布林组合进行药物选.
- 使用OCS细胞系,有机体和患者衍生异种移植 (PDX) 模型进行验证.
- 研究了潜在的阻力机制和信号通路的依赖性.
主要成果:
- 基于埃里布林的组合在OCS有机体模型中最有效,而西斯的组合在高度血清性卵巢癌 (HGSOC) 中更有效.
- 埃里布林与EGFR抑制剂埃洛提尼布或MEK抑制剂米尔达美提尼布结合在OCS模型中显示出协同效应.
- 药物耐药性机制,包括ABCB1表达和KRAS突变,在体内被确定;双重EGFR/MAPK向与埃里布林在耐药性模型中表现出增强的协同作用.

Mitogens and the Cell Cycle
6.3K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

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.
