ANTICANCER, INC., DEVELOPS TECHNOLOGY TO EXTERNALLY IMAGE SINGLE CANCER CELLS IN MICE

San Diego, March 14, 2002.  AntiCancer, Inc., announced today new external imaging technology that allows direct visualization of single tumor cells growing internally in the mouse, increasing detection sensitivity many-fold.   Many tumors that were previously hidden are now clearly observable with AntiCancer’s new technology.  The new technology enables acquisition of tumor images and related quantitative growth data previously impossible to obtain.   Single tumor cells, genetically engineered to express the jellyfish green fluorescent protein (GFP), growing on the brain, lung, liver, and pancreas were externally imaged by fluorescent light.  These new findings are published in the latest edition of The Proceedings of the National Academy of Sciences USA.

”This new single-cell-resolution fluorescent tumor imaging technology is a breakthrough,” said AntiCancer’s Vice President and General Manager, Shigeo Yagi.  “We can now follow single internal tumor cells externally to develop drugs that prevent recurrence from previously undetectable tumor cells, which is a major cause of death in cancer of the breast and other tumors.  We expect to use or license this new imaging technology with the numerous pharmaceutical and biotechnology companies now using our mouse models for cancer drug discovery, evaluation, and development” said Dr. Yagi.

AntiCancer, founded in 1984 and based in San Diego, is also developing new drugs for cancer based on genetic engineering, targeting cancer specific metabolic defects.  The company is also developing diagnostics for cancer and other diseases as well as gene therapy of cancer and other diseases.
