Abstract: Described are cell surface and circulating markers for aging related disorders (specific isoforms of NADH oxidase (arNOX)). Recombinant age-related NADH oxidase isoforms and their coding sequences and methods for detecting arNOX isoform presence and quantitation in tissues and in blood, sera, urine, saliva, perspiration and in other body fluids, are provided. Recombinant arNOX proteins are useful in preparing antigens for use in the generation of monoclonal and polyclonal antibodies as well as immunogenic compositions for diagnosis and treatment of aging disorders. DNA probes based on the DNA sequence information provide may be used to identify individuals at risk for aging disorders and for development of therapeutic interventions or anti-aging cosmetic or other formulations of benefit in slowing the aging process in mammals.

Abstract: The invention relates to agents for sequestering serum aging factors, and methods for using the same. More particularly, the invention relates to agents termed herein “Naractin” to denote any one of several naturally-occurring arNOX inhibitors either present in N. tazetta powder or capable of augmenting N. tazetta powder to an inhibitory level comparable to that of the fresh N. tazetta extracts, and to methods for using “Naractins” to prevent or treat disorders and complications of disorders resulting from cell damage caused by an aging-related isoform of NADH oxidase (arNOX). In one exemplary embodiment the agents of the invention comprise at least one naturally occurring Naractin. Such naturally occurring naractins are also capable of augmenting the anti-arNOX effect of other naturally occurring arNOX inhibitory agents.
