Mice were inoculated with an HT-1080 fibrosarcoma xenograft and subjected to target-specific antivascular therapy using a selective thrombogenic vascular-targeting agent (truncated tissue factor fused to RGD peptide) or saline as control.
A polypeptide factor produced by fibrosarcoma cells that induces endothelial tissue factor and enhances the procoagulant response to tumor necrosis factor/cachectin.
Luciferase reporter gene assays and Western blot analysis in human fibrosarcoma HT1080 cells and HMC were performed to analyze the effect of simvastatin on the transcription factors nuclear factor kappa B (NF-kappa B) and activator protein-1 (AP-1), which regulate tissue factor gene expression.
To evaluate whether TF overexpression in tumor cells modulates its shedding and neighboring stromal cells by its catalytic or intracellular activity, TF-GFP (green fluorescent protein) and a tailless form (TFDeltaC-GFP) were stably expressed in the rat Morris hepatoma and human HT1080 fibrosarcoma cell lines.
