Understanding the host response to oncolytic viruses is important to maximize their antitumor efficacy. Despite robust cytotoxicity and high virus production of an oncolytic herpes simplex virus (oHSV) in cultured human sarcoma cells, intratumoral (ITu) virus injection resulted in only mild antitumor effects in some xenograft models, prompting us to(More)
AIM Our previous investigations of angiogenesis in inflammatory bowel disease showed that vascular endothelial growth factor (VEGF) blockade reduced colonic neovascularization and inflammation. We hypothesized that pretreatment with bevacizumab, a monoclonal anti-VEGF antibody, would attenuate the severity of angiogenesis and inflammation in a murine model(More)
BACKGROUND Expression of epidermal growth factor receptor (EGFR), a potent regulator of cellular homeostasis, is associated with aggressive tumor behavior. The mechanism by which EGFR inhibition functions is unclear, with controversial results demonstrating an effect on the tumor cells, endothelial cells, or pericytes. EGFR activation has been linked to the(More)
BACKGROUND In the setting of inflammatory bowel disease, inflammation is associated with a simultaneous increase in angiogenesis; moreover, elevated vascular endothelial growth factor (VEGF) levels implicate angiogenesis as a pathologic contributor to disease severity. We hypothesize that selectively inhibiting vascular endothelial growth factor receptor-2(More)
BACKGROUND Angiogenesis is a known pathologic factor in chronic inflammatory diseases. Regarding the murine dextran sodium sulfate (DSS) colitis model, different mouse strains produce variable clinical and inflammatory responses. We hypothesize that DSS colitis applied to diverse mouse strains will similarly elevate colonic microvessel density in parallel(More)
BACKGROUND Angiogenesis, a known pathogenic component of neoplastic and nonneoplastic diseases, serves as a therapeutic target. Vascular endothelial growth factor (VEGF) and angiogenesis are clinically elevated in inflammatory bowel disease. By targeting vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR)(More)
Angiogenesis is a component of chronic inflammatory diseases including inflammatory bowel disease. Some studies describe increased angiogenesis associated with acute disease in adult Crohn’s disease and ulcerative colitis, while animal models aid investigations of mechanism and pathophysiology of angiogenesis. We aim to explore the role of angiogenesis and(More)
