This study investigated the functional interplay between vascular endothelial growth factor (VEGF) and metalloproteinases (MMPs) in ovarian carcinomas. Levels of MMP9 (pro and activated form) and proMMP2 in ascites correlated with VEGF and with the ascitic volume in nude mice bearing human ovarian carcinoma xenografts (HOC22 and HOC8). The MMP inhibitor(More)
Endothelial cell migration is a critical event during angiogenesis, and inhibitors of cell motility can affect the angiogenic process. Paclitaxel (Taxol(R)), a microtubule-stabilizing antineoplastic cytotoxic drug, inhibits motility and invasiveness of several cell types. The aim of this study was to investigate the effect of paclitaxel on endothelial cell(More)
PURPOSE The purpose of this study was to investigate the antiangiogenic properties of 17-(dimethylaminoethylamino)-17-demethoxygeldanamycin (17-DMAG; NSC707545), a water-soluble benzoquinone ansamycin. EXPERIMENTAL DESIGN The activity of 17-DMAG, in vivo, was evaluated for inhibition of fibroblast growth factor (FGF)-2-induced angiogenesis in s.c.(More)
Vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMP) regulate each other, contributing to tumor progression. We have previously reported that MMP9 induces the release of tumor VEGF, promoting ascites formation in human ovarian carcinoma xenografts. The aim of this study was to investigate whether tumor-derived VEGF regulated the(More)
BACKGROUND Bevacizumab is being incorporated as first-line therapy with standard-of-care chemotherapy on epithelial ovarian carcinoma (EOC). We investigated bevacizumab combined with chemotherapy on tumour progression and mouse survival in EOC xenograft models. METHODS Bevacizumab was administered concomitantly with cisplatin plus paclitaxel (DDP+PTX),(More)
Cediranib is a pan-vascular endothelial growth factor receptor tyrosine kinase inhibitor that affects tumor angiogenesis and is under investigation in clinical studies on ovarian cancer. Using a panel of eleven patient-derived ovarian cancer xenografts (EOC-PDX) growing orthotopically in the peritoneal cavity of nude mice we investigated the effect of(More)
