是的相关蛋白1 (YAP1) 和TEA域转录因子4 (TEAD4) 是Hippo通路的关键作用器. 高TEAD4表达,但不是YAP1,与侵袭性清细胞细胞癌 (CCRCC) 和低生存率有关,这表明TEAD4是治疗点.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 信号通道的信号通道
背景情况:
- 河马信号通路调节器官大小,在瘤发生过程中至关重要.
- 是的相关蛋白1 (YAP1) 和TEA域转录因子4 (TEAD4) 是Hippo通路的关键下游影响者.
- 这种途径的放松调节与癌症的发展和进展有关,特别是清细胞细胞癌 (CCRCC).
研究的目的:
- 在CCRCC中评估YAP1和TEAD4的mRNA表达.
- 研究YAP1和TEAD4在CCRCC中的临床病理和预后作用.
- 确定YAP1和TEAD4作为CCRCC中的生物标志物和治疗点的潜力.
主要方法:
- 使用基因表达特征交互分析 (GEPIA) 数据库进行mRNA表达分析.
- 对349个手术切除的清细胞细胞癌 (CCRCC) 样本进行了免疫组织化学分析.
- 与临床病理学变量和患者存活率 (总体存活率和无病存活率) 相关联的YAP1和TEAD4表达.
主要成果:
- 高YAP1表达在16.3%的病例中被观察到,并且只与低核级相关.
- 在37.5%的病例中观察到高TEAD4表达,并且与较大的瘤大小,高核级,淋巴血管入侵,先进的PT分类,先进的临床阶段,瘤分化和转移有显著的相关性.
- 低YAP1 / 高TEAD4表达与积极的临床病理特征和较差的结果有关. 高TEAD4表达与较短的OS和DFS相关,但不是一个独立的预后因素.
结论:
- TEAD4,但不是YAP1,在CCRCC进展中发挥着关键作用,独立于YAP1.
- 高TEAD4表达与CCRCC患者的不良临床病理因素和更差的存活率有关.
- TEAD4代表了CCRCC的潜在生物标志物和治疗点.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
