SAN DIEGO--(BW HealthWire)--Feb. 26, 2001

AntiCancer Inc. scientists announced today that they have developed a new technology that enables angiogenesis, or blood vessel formation, in tumors tumor /tu·mor/ (too´mer)
1. swelling, one of the cardinal signs of inflammation; morbid enlargement.
2. neoplasm; a new growth of tissue in which cell multiplication is uncontrolled and progressive.
 to be non-invasively imaged in mouse models of cancer.

The technology involves genetically engineering tumor cells to become highly fluorescent by expressing the jellyfish

2. Any of various similar or related coelenterates.

). When the genetically fluorescent tumors are transplanted to appropriate mouse models, the tumor blood vessels, which originate from the host animals, are readily quantitatively whole-body imaged by their stark contrast to the fluorescent tumors. The mice are not perturbed in the imaging process -- only a blue light is shined on them causing the tumors to glow a bright green with the blood vessels appearing black. The fluorescent tumor models can then be used for drug discovery and evaluation in the worldwide effort to find drugs that are effective against tumor blood vessel formation. Attacking tumor angiogenesis is thought to be one of the most promising targets to arrest and reverse metastatic tumor growth. AntiCancer's new angiogenesis model is described in the current issue of the Proceedings of the National Academy of Sciences, USA.

Dr. Shigeo Yagi, general manager of AntiCancer said, "With AntiCancer's new development, there is, for the first time, a relevant and useful animal model of tumor angiogenesis. Tumor angiogenesis can now be followed non-invasively in real time by whole-body imaging. This should now enable efficient drug discovery in this critical process of tumor growth and metastasis
1. transfer of disease from one organ or part of the body to another not directly connected with it, due either to transfer of pathogenic microorganisms or to transfer of cells; all malignant tumors are capable of metastasizing.
2. a growth of pathogenic microorganisms or of abnormal cells distant from the site primarily involved by the morbid process.
." AntiCancer is currently utilizing its unique animal models of cancer to help pharmaceutical and biotechnology companies worldwide to discover and develop effective drugs for cancer.

AntiCancer, based in San Diego, has also developed whole-body fluorescent imaging technology to visualize tumor growth and metastasis non-invasively in mouse models. The company in addition is developing genetically-engineered cancer drugs; gene therapy for cancer and hair loss; as well as genetically-engineered diagnostics of cancer and cardiovascular disease through its A/C Diagnostics subsidiary. AntiCancer has 40 employees.
