The fact that tumor growth and metastatic spread relies on angiogenesis has been widely proven and accepted. The understanding of cancer biology and metastasis formation has led to the development of new therapeutic approaches that target tumor biology. The survival and establishment of metastatic lesions depend on a shift in the normal balance of proangiogenic and antiangiogenic factors that favor...
We determined whether the upregulation of several metastasis-related genes in human colon carcinoma (HCC) cells implanted into the cecal wall of nude mice precedes HCC invasion of the muscle layer and subserosa and, ultimately, distant metastasis. HCC KM12SM cells were implanted into the subcutis (ectopic) or cecal wall (orthotopic). At weekly intervals for up to 6 weeks, cecectomy and resection...
