概括

大细胞神经内分泌癌 (LCNEC) 可以根据NEUROD1,ASCL1,POU2F3和YAP1 (NAPY) 表达分为五种亚型. 这些亚型提供了适度的歧视,并可能指导未来的个性化治疗策略.

科学领域:

癌症学
分子病理学
基因组学

背景情况:

大细胞神经内分泌癌 (LCNEC) 呈现基因组异质性,其亚型类似于小细胞肺癌 (SCLC) 和非SCLC (NSCLC).
之前的研究发现NEUROD1,ASCL1,POU2F3和YAP1 (NAPY) 是SCLC的关键亚型.

研究的目的:

在切除的LCNEC中免疫组织化学评估NAPY亚型.
将NAPY表达与蛋白质标记物 (pRb,DLL3,cMYC,TTF1) 和临床数据相关联.
在LCNEC中确定基于表达的分组.

主要方法:

从133个I-III阶段切除的LCNEC组织微阵列进行了分析.
对NAPY,pRb,DLL3,cMYC和TTF1进行了免疫组织化学测试.
使用无监督聚类和空间免疫RNA分析 (GeoMX DSP).

主要成果:

基于表达的五个子组被确定为:NEUROD1高-ASCL1高 (10%),ASCL1高 (22%),POU2F3高 (5%),YAP1高 (11%) 和NAPYlow (51%).
与DLL3高和高的神经内分泌标志物表达相关的ASCL1高子组.
在POU2F3高和YAP1高的子组中,神经内分泌标志物和DLL3表达水平较低.
与SCLC相比,LCNEC的NAPY低和YAP1高的比例更高,POU2F3高的病例更少.

结论:

在LCNEC中应用NAPY标记物确定了五个具有不同蛋白质表达特征的分组.
NEUROD1高-ASCL1高和ASCL1高分组与DLL3高表达相关.
虽然提供了适度的歧视,但这些子组突出显示了与SCLC的潜在差异,并要求对向治疗进行进一步的研究,特别是关于DLL3和YAP1的表达.

Notch Signaling Pathway

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
