概括
与没有癌症的人相比,癌症患者在细胞外囊泡 (EV-TF) 上显示出较高水平的组织因子,无论静脉血栓塞栓症 (VTE) 是否存在. 这表明癌症本身驱动了EV-TF生成,这是血液凝固的关键因素.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 生物化学 生物化学
背景情况:
- 癌症与慢性炎症和高凝血性有关,增加了静脉血栓栓塞 (VTE) 的风险.
- 组织因子 (TF) 在细胞外囊泡 (EVs) 上启动血液凝结.
- 有限的研究存在于与癌症相关的VTE与其他类型的VTE之间的EV-TF差异.
研究的目的:
- 为了比较细胞外囊泡相关组织因子 (EV-TF) 在未引起的VTE (U-VTE),癌症相关的VTE (C-VTE) 和没有VTE的癌症 (C-w/o VTE) 的水平.
- 在这些患者群体中调查介质素-6 (IL-6) 水平.
主要方法:
- 在68名患者 (15 U-VTE, 24 C-VTE, 29 C-w/o VTE) 中比较了EV-TF和IL-6水平.
- 通过微分离离心,从外围血液中分离出EVs.
- 使用一步凝血试验测量TF.
主要成果:
- 与U-VTE组相比,在C-VTE和C-w/o VTE组中观察到显著更高的EV-TF水平 (p=0.024).
- 在C-VTE和C-w/o VTE组之间没有发现EV-TF的显著差异.
- 两组之间的IL-6水平没有显著差异.
结论:
- 癌症,独立于VTE,似乎是产生EV-TF的重要驱动因素.

02:17The Tumor Microenvironment
6.5K
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...

5.0K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

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...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
