概括

这项研究使用多种omics数据确定了两种结直肠癌 (CRC) 亚型,揭示了不同的临床结果和精确瘤学的潜在生物标志物. 一个亚型显示出不良预后和改变的途径,为未来的CRC治疗策略提供信息.

科学领域:

基因组学就是基因组学.
分子生物学分子生物学
在瘤学瘤学.

背景情况:

大肠直肠癌 (CRC) 呈现出多样化的分子形状和有限的预后标志物.
多omics数据为完善CRC分类和理解其复杂性提供了一个有希望的途径.

研究的目的:

在CRC中使用集成的多omics数据来定义共识分子亚型 (CMS).
阐明这些亚型与临床结果,生物过程和潜在的治疗反应的关联.

主要方法:

在TCGA-CRC数据 (mRNA, lncRNA, miRNA,甲基化,突变) 上应用了十个集成的多omics集群算法.
分析了亚型与预后,功能,免疫力和基因组变化的关联.
开发了一个使用单变Cox和Lasso回归的预后模型,在CRC细胞系中验证了MID2基因功能.

主要成果:

确定了两种CRC亚型 (CS1,CS2) 具有不同的预后,在数据集中验证.
CS1亚型与预后不佳,瘤通路活性较高,新陈代谢较低,免疫疗法反应减少和更多的基因组变化有关.
一个五基因预后模型与亚型保持一致;MID2与EMT和甲基化相关,其淘汰降低了CRC细胞的侵入性.

结论:

综合性多组子类型为CRC提供了潜在的生物标志物.
这些发现为推进结直肠癌管理中的精确瘤学提供了宝贵的见解.

关键词:

结肠直肠癌是一种癌症.在MID2中,MID2是指MID2.分子子类型的分子.多个omics的个人资料.预后标志物是一个预后标志物.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
