About Cerium Oxide Nanoparticles
The production of hydrogen peroxide, a Reactive Oxygen Species (ROS) from radiation is a critical function for how radiation damages the DNA of cells of the tissue it passes through. BioCurity’s cerium oxide nanoparticles possess fast catalase activity in a normal tissue’s neutral pH environment and reduces radiation-induced hydrogen peroxide to molecular oxygen, thereby preventing radiation damage of normal tissue. BioCurity’s cerium oxide nanoparticles also possess superoxide dismutase activity in a cancerous tissue’s acidic pH environment and converts superoxide to hydrogen peroxide, thereby enhancing radiation-induced ROS damage of cancerous tissue.
BioCurity’s extensive preclinical studies in models of head and neck, lung, breast, pancreatic, prostate, and colorectal cancer show cerium oxide nanoparticles are regenerative and are not consumed in the reaction. Administration of cerium oxide nanoparticles at 1,000 times the effective dose did not produce toxicity in a small animal model.
