概括

胸膜上皮瘤 (TETs) 显示了亚型特定的Hippo通路变化. 在某些TET亚型中,增强的YAP1/TEAD4转录和减少的MST1/LATS1激酶表明了层分化的潜在生物标志物.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
癌症基因组学癌症基因组学

背景情况:

胸膜上皮瘤 (TETs) 是罕见的,缺乏特定的分子生物标志物.
河马通路失调,特别是YAP/TEAD转录活性,与各种癌症有关.
对于TETs中的Hippo路径存在有限的转录级数据.

研究的目的:

为了研究世界卫生组织 (WHO) 不同类型的TETs中核心Hippo通路组件的表达模式.
为了确定TET亚型分层化的潜在分子生物标志物.

主要方法:

在SYBR实时定量聚合酶链反应 (RT-qPCR) 中,对23个TET和3个正常胸腺FFPE标本进行了实时定量聚合酶链反应.
我们量化了YAP1,TEAD4,MST1,SAV1,LATS1和MOB1A的表达水平.
数据被规范化并使用2^-ΔΔCq方法和非参数测试对WHO亚型的差异表达进行分析.

主要成果:

观察到亚型依赖于YAP1和TEAD4的上调,特别是在甲状腺瘤类型A和B3和甲状腺癌 (TC) 中.
上游激酶MST1和LATS1显著减少,特别是在TC中.
在A型和B3型中,SAV1表达升高,而MOB1A保持在基线附近;在亚型中,SAV1,MST1和LATS1的YAP1,TEAD4,SAV1的差异表达显著.

结论:

TETs显示出与组织学亚型相关的Hippo途径组件的独特表达特征.
增强的YAP1-TEAD4转录输出和减少的MST1/LATS1激酶活性是特异性TET亚型的特征,特别是TC.
这些发现提名了TET亚型分层化候选分子标记物,并需要进一步的临床验证.

关键词:

Hedgehog Signaling Pathway

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
