概括
在瘤中高CD112表达与预后不佳和免疫细胞透率降低相关. 这表明CD112可能是一个预后标志物,并通过表皮-介质细胞过渡 (EMT) 驱动瘤生长.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 分子生物学分子生物学
背景情况:
- CD112 (内素粘附分子) 涉及到瘤的进展.
- 缺乏对CD112的临床相关性和跨癌症机制的全面评估.
研究的目的:
- 研究CD112在癌症中的预后价值和功能作用.
- 探索CD112表达和瘤免疫力,突变负担和甲基化之间的关系.
- 评估CD112对癌细胞行为和免疫治疗反应的影响.
主要方法:
- 使用了癌症基因组图谱 (TCGA) 和基因型-组织表达 (GTEx) 数据库.
- 分析了与瘤突变负担 (TMB),DNA甲基化,免疫入侵,不匹配修复 (MMR),微卫星不稳定性 (MSI) 和免疫检查点抑制剂 (ICI) 相关的CD112表达.
- 在结直肠癌 (CRC) 细胞系中进行了CD112淘汰实验,并分析了上皮细胞到介质细胞转换 (EMT) 途径.
主要成果:
- 恶性组织显示CD112水平升高,与TMB,MMR,MSI和DNA甲基化有关.

Metastasis
5.5K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cadherins in Tissue Organization
3.0K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
