( HOUSTON--(BUSINESS WIRE)--May 23 2007 ...)CytoGenix to Present at 2007 International DNA Vaccines Conference,in Spain,Health

HOUSTON--(BUSINESS WIRE)--May 23, 2007 - CytoGenix, Inc. (CYGX.OB) announced today that Dr. Yin Chen, Chief Scientific Officer will present an update on preclinical animal data for DNA vaccines made using the Company's proprietary synDNA(TM) technology at the 2007 DNA Vaccines conference to be held in Malaga, Spain between May 23 and May 25.

Dr. Chen comments, "We have successfully conducted tests of synDNA(TM) based vaccines in mice, rabbits and non-human primates. The data to be presented will demonstrate the stimulation of the immune response comparing synDNA(TM) based vaccines to traditional plasmid DNA vaccines designed for the prevention of seasonal flu, HIV, smallpox and Hepatitis B. The tests indicate that the immune response triggered by synDNA(TM) vaccines is comparable to, and in some cases more effective than responses mediated by plasmid DNA. Data will also be shown demonstrating the effectiveness of a novel vaccine that protects against a highly virulent form of avian (bird) flu in animal challenge studies. These challenge experiments demonstrated that synDNA(TM) is just as effective as plasmid in mediating a protective immune response when the host is attacked by virulent viruses.

Malcolm Skolnick, CEO, states, "DNA vaccines have proven to be a potent means of providing protective immunity against viruses, bacteria and parasites in many species from fish to primates. Our animal tests demonstrate that DNA vaccines made with synDNA(TM) technology are not only effective in eliciting robust immune responses, but also provide protection against dangerous pathogens. Presentation of our data at the DNA vaccine conference is a great opportunity to showcase and discuss our work with other experts in this field including major pharmaceutical and biotech companies."
