Kyto Biopharma Inc. Confirms Isolation of the Human Vitamin B12 Receptor (TCblR)
"The discovery of the TCblR gene and the expression of its encoded receptor protein represents a seminal milestone in the annals of cellular biology," commented Dr. Uri Sagman, a founder and a director of Kyto. "Targeting TCblR in cancer cells with monoclonal antibodies holds a tremendous promise as a strategy to combat cancer," added Dr. Sagman.
The isolation of the TCblR gene and the expression of the TCblR protein was achieved by Dr. Edward Quadros and his team at the State University of New York (SUNY) at Downstate Medical Center. In addition, the team at SUNY has successfully expressed the fragment of the receptor protein responsible for binding to the transcobalamin - B12 complex. Kyto has embarked on a program to develop targeted human monoclonal antibodies to TCblR as therapeutics for various forms of cancer. In addition, Kyto intends to couple chemotherapeutic drugs and metabolic toxins to such therapeutic monoclonal antibodies and enhance their biological activity as powerful targeting agents.
Kyto has entered into an arrangement with third party providers to manufacture murine antibodies that will be used in the development of humanized monoclonal antibodies to TCblR. Dr. Quadros, with the input of Dr. Michael Rosenblum of MD Anderson Cancer Center, and a director of Kyto, will oversee the development of the monoclonal antibody program on behalf of the Company.

Antibodies are specialized molecules of our immune system that can specifically recognize and neutralize pathogens or foreign substances. Antibody research in biotech and pharma has recognized this natural defense potential and is working intensively to make it therapeutically useful. From monoclonal antibodies used against cancer or autoimmune diseases to antibody-drug conjugates that specifically transport drugs to disease cells - the possibilities are enormous
