Entia Biosciences Receives Canadian Patent Notice of Allowance for Use of Ergothioneine and Its Genetic Transporter

SHERWOOD, Ore., Dec. 17, 2012 /PRNewswire/ -- Entia Biosciences (OTCBB: ERGO), a food science biotechnology company and emerging leader in the fields of Nutrigenomics and Targeted Nutrition, has received a Patent Notice of Allowance from the Canadian Intellectual Property Office covering the use of Ergothioneine and its genetic transporter (SLC22A4) in the treatment of a wide variety of diseases, including those affecting the immune and central nervous systems. Ergothioneine is a powerful amino acid and master antioxidant that is acquired exclusively from the diet and carried by this unique and specific transporter to cells throughout the body that are fighting damage and death from oxidative stress and toxic free radical reactions. Research conducted by Entia since 2011 has confirmed significant transporter activity in diabetes, arthritis, and several other serious non-communicable chronic conditions, suggesting an important physiologic role for Ergothioneine in diseases affecting millions of people world-wide.

"We are very pleased that our intellectual property estate on Ergothioneine is advancing nicely alongside the scientific, clinical and other business developments at Entia," said Marvin S. Hausman MD, Chairman and Chief Executive Officer. "The issuance of this important foundational patent significantly enhances the commercialization strategy for our ErgoD2 line of proprietary medical foods, functional ingredients, and other nutritional supplementation solutions in 2013 and for the potential development of a commercial diagnostic test that could one day identify specific dietary deficiencies."

Found in naturally high concentrations almost exclusively in mushrooms and other fungi, Ergothioneine is transferred directly from these sources into the soil, where it is taken up by plants and grazing mammals. For thousands of years, our hunter/gatherer genetics have relied on this process to maintain adequate levels of Ergothioneine to prevent or delay the onset and progression of disease. Entia theorizes introduction of modern agricultural practices in the past century, such as the heavy use of chemical fertilizers, insecticides, and over tilling of the soil, has been gradually eradicating mushrooms from our farmland and depleting Ergothioneine from the food supply. During this same period, our dietary habits have been changing, which Entia believes is further accelerating deficiency in the general population and may explain the dramatic increases we are now seeing in diabetes, arthritis, neurodegenerative, and other debilitating diseases. This deficiency theory is supported by human blood testing conducted in the late 1920s1 that showed "normal" Ergo levels nearly double those found by Pennsylvania State University in 20102.

Discovered in 2005 by Dr. Dirk Grundemann at the University of Cologne (Germany), SLC22A4 is a sodium-ion dependent transporter that efficiently and specifically carries Ergothioneine across the cell membrane to erythrocytes (red blood cells), progenitor stem cells, and monocytes (white blood cells) (Grundemann, 2005). Variations in SLC22A4 have been associated with susceptibility to inflammatory disorders, such as rheumatoid arthritis and Crohn's disease, and expression has been documented in a variety of human tissues. Entia licensed the exclusive world-wide diagnostic and therapeutic rights to the discovery from the University of Cologne in 2010 and Dr. Grundemann currently serves on Entia's Scientific Advisory Board.

Dr. Solomon Snyder of Johns Hopkins University School of Medicine has suggested that Ergothioneine is as potent as glutathione and because of its dietary origin and the toxicity associated with its depletion, it may represent a new vitamin whose physiologic roles include antioxidant cytoprotection. Dr. Snyder further believes that the high density of Ergothioneine within mitochondria implies a unique role in protecting mitochondrial DNA from damage induced by free radicals and reactive oxygen species (Snyder, 2009). Mitochondria are cytoplasmic organelles responsible for life and death. Evidence from animal and clinical studies suggest that mitochondria play a critical role in aging, cancer, diabetes and neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease (Simon, 2004; Lin, 2006; Reddy, P.H., 2009). Further supportive evidence of the potential protective role of Ergothioneine was recently shown by the presence of elevated levels in the red blood cells of pregnant women with the condition preeclampsia. There is currently no known cause for this condition, which affects nearly 10% of pregnancies reaching 20 weeks. The symptoms of preeclampsia include high blood pressure, protein in urine, and fluid retention and left untreated the condition can cause a range of problems such as growth restriction in babies and even fetal and maternal mortality. Ergothioneine is known as an antioxidant and antioxidants have been proposed to be helpful in reducing the risk of preeclampsia. It is therefore very interesting that we have found it to be in excess for women with the condition (Turner, E., 2009)."
