概括
这项研究揭示了表皮-介质细胞转变 (EMT) 标记物,特别是维门丁和瘤芽,是三阴性乳腺癌 (TNBC) 攻击性的关键指标. 高的EMT指数与侵袭性疾病相关,而瘤透性淋巴细胞 (TIL) 表明对TNBC进展有有效的免疫反应.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症研究 癌症研究
背景情况:
- 三阴性乳腺癌 (TNBC) 是一种具有攻击性的亚型,缺乏关键的治疗点.
- 驱动TNBC攻击性的分子机制尚未完全理解.
- 表皮介质转变 (EMT) 越来越多地与癌症的进展和转移有关.
研究的目的:
- 调查TNBC进展与EMT相关标志物 (维门丁,β-catenin,E-cadherin) 之间的关联.
- 评估瘤芽和瘤透淋巴细胞 (TILs) 与TNBC中的EMT指数相关的作用.
主要方法:
- 在137个初级TNBC瘤,瘤芽和淋巴结转移中对维门丁,β-catenin和E-cadherin进行免疫组合化学分析.
- 计算一个EMT指数 (vimentin + beta-catenin / E-cadherin).
- 统计分析包括皮尔森相关性,多重线性回归和Kruskal-Wallis测试,以评估EMT指数,瘤芽和TIL之间的关系.
主要成果:
- 维门丁表达在不同区域与自身有很强的相关性 (r=0.90-0.92).
- 强烈的负相关性之间的E-cadherin和维门丁 (r=-0.81到-0.89) 突出了EMT.
- 该EMT指数显示出与瘤芽的存在有很强的关联 (r=0.91) 和与TILs的反相关性 (r=-0.90).
结论:
- EMT标记物,特别是维门和瘤芽,是TNBC攻击性的关键指标.
- 瘤芽可以作为侵略性TNBC的预后指标,识别高风险患者.
- 有效的免疫反应 (用TILs表示) 可能抵消EMT驱动的TNBC进展,这表明需要多标志物治疗策略.

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...

Tumor Progression
6.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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...

The Tumor Microenvironment
6.6K
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...
