概括

胃癌中新辅助化疗 (NAC) 反应与瘤增殖和免疫细胞透有关. 五个特定的基因 (ZNF296,RASSF10,EXOC3L1,KIAA0895,GALNTL1) 在非响应者中表达减少,这表明潜在的生物标志物.

科学领域:

在瘤学瘤学.
基因组学就是基因组学.
免疫学免疫学免疫学

背景情况:

胃癌的预后很差,在日本,新辅助化疗 (NAC) 的使用有限.
基于多西的疗法在国际上显示出前途,但它们的生物机制需要阐明.

研究的目的:

为了确定病理响应者和非响应者之间的关键生物学差异,以dcetaxel为基础的NAC.
为了研究用NAC治疗的胃瘤的转录组概况.

主要方法:

从24名胃癌患者的瘤切片的转录组分析,这些患者接受了多塞塔塞尔加S-1 (DS) 或多塞塔塞尔加思加S-1 (DCS) 的治疗,作为NAC.
响应组和不响应组之间的基因表达特征的比较.

主要成果:

非响应者表现出更糟糕的预后,丰富的增殖相关的基因组和较低的CD8+和CD4+效应体记忆细胞和树突细胞的透.
在关键免疫路径 (如干扰素-γ和干扰素-α反应) 中没有发现显著差异.
在没有反应的组中发现五种基因 (ZNF296,RASSF10,EXOC3L1,KIAA0895,GALNTL1) 的表达显著降低.

结论:

缺乏NAC反应与瘤扩散增加,抗瘤免疫力低下以及ZNF296,RASSF10,EXOC3L1,KIAA0895和GALNTL1.1的表达减少有关.
这五种基因是预测NAC疗效和胃癌新疗法标的潜在生物标志物.

关键词:

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

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...
