Results of Colon Cancer Study Utilizing Pressure Cycling Technology (PCT) Presented at the American College of Gastroenterology Annual Scientific Meeting

WEST BRIDGEWATER, Mass., Oct. 17 /PRNewswire-FirstCall/ -- Pressure BioSciences, Inc. (Nasdaq: PBIO) ("PBI") today announced that a study focused on the discovery and identification of potential biomarkers of colon cancer that used pressure cycling technology (PCT) for the extraction of proteins from colon cancer tissues was presented on Sunday, October 14, 2007 at the Annual Scientific Meeting of the American College of Gastroenterology (ACG). The data were generated by scientists at the Brooklyn Hospital Center and the New York University (NYU) School of Medicine. The poster presentation was made by Dr. M. Momeni, MD of the Department of Gastroenterology of the Brooklyn Hospital Center.

Colon cancer is the second leading cause of cancer death in the United States. The probability of cure is directly related to the stage of the cancer at diagnosis and surgical resection. Identifying patients with this disease who have been shown to benefit from therapy is difficult at the present time due to the lack of reliable biomarkers. The purpose of this study was to identify proteins in tissue samples from patients with colon cancer that might be reliable biomarkers for this disease. To this end, pressure cycling technology (PCT) was used to extract the proteins from the various tissue samples that were studied.

Dr. Alexander Lazarev, Vice President of Research and Development of Pressure BioSciences, said: "The data presented by Dr. Momeni and her colleagues indicate that an apparent tumor signature protein (hCG1787564) extracted from colon tumor tissue by PCT might be a biomarker that could be of benefit to surgeons treating colon cancer patients. It is gratifying that PCT is beginning to be used by independent scientists in the preparation of their samples for important scientific studies, such as in the case of colon cancer research."
