Hypoxic induction of Matriptase expression was confirmed by Northern blot analysis and Western blot analysis. Localization of Matriptase expression in tissue specimens revealed expression primarily by ductal

In the C57B1/6 model, B16 tumors grew for 2–3 weeks before mice died from tumor complications. However, rapamycin treatment protected allografts, permitted animal survival, and inhibited tumor growth. In contrast, cyclosporine-treated mice died from advan

In vitro proliferation was quantified by MTT assay, VEGF production by VEGF ELIS A (R&D systems). VEGF expression and microvessel density of experimental tumors were quantified by morphometric analysis after immunohistocemical staining with anti VEGF and CD 31 antibodies. .: An antiproli
