|January 1, 1994
Summary
Cancer cell lines with higher metastatic potential exhibit increased tissue factor (TF) levels, a key procoagulant. This study links TF expression to aggressive cancer cell characteristics, offering insights into cancer progression and TF
Area of Science:
- Oncology
- Biochemistry
- Cell Biology
Background:
- Cancer cell lines with varying metastatic potential were analyzed for procoagulant activity.
- Metastatic potential was associated with high histological grade, origin from metastatic tumors, increased tumorigenicity, and estrogen receptor-negative status.
Purpose of the Study:
- To investigate the procoagulant activity of cancer cell lines with different metastatic properties.
- To determine the role of tissue factor (TF) in the procoagulant activity of these cell lines.
Main Methods:
- Procoagulant activity was measured using a two-stage clotting assay.
- Tissue factor antigen expression was quantified by ELISA.
- Tissue factor mRNA levels were assessed using northern blot analysis.
Main Results:
- Procoagulant activity varied significantly among cell lines, with tissue factor identified as the primary contributor.
- Higher tissue factor antigen levels correlated with increased procoagulant activity.
- Cancer cell lines with characteristics suggesting greater metastatic potential consistently showed higher tissue factor levels.
Conclusions:
- Tissue factor is the predominant procoagulant in these cancer cell lines.
- Increased tissue factor expression is linked to more aggressive cancer cell phenotypes.
- These findings highlight the role of tissue factor in cancer progression and metastasis.
