概括

梅索林 (MSLN) 在侵袭性三阴性乳腺癌 (TNBC) 中高度表达,与化学疗法反应不佳和瘤血栓增加相关. 针对MSLN可能为TNBC患者提供新的治疗策略.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
基因组学就是基因组学.

背景情况:

三阴性乳腺癌 (TNBC) 是一种具有有限治疗选择的侵袭性亚型.
瘤抗原梅索林 (MSLN) 在一些TNBC中表达,但其临床病理学作用未得到充分研究.

研究的目的:

调查TNBC中MSLN表达的临床病理特征和治疗影响.
探索MSLN与瘤微环境和治疗反应的关联.

主要方法:

全癌症分析以确定MSLN的显著性.
局部队列分析MSLN表达,瘤微环境和化疗反应.
空间转录和单细胞TNBC数据分析.

主要成果:

MSLN表达与TNBC中的免疫抑制性瘤微环境有关.

Metastasis

Metastasis

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...

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...
