All rights reserved 0891-5849/02/$–see front matter PII S0891-5849(02)00956-5 Review Article STRUCTURE AND FUNCTION OF XANTHINE OXIDOREDUCTASE: WHERE ARE WE NOW? ROGER HARRISON Department of Biology and Biochemistry, University of Bath, Bath, UK (Received 11 February 2002; Accepted 16 May 2002) Abstract—Xanthine oxidoreductase (XOR) is a complex molybdoflavoenzyme, present in milk and many other tissues, which has been studied for over 100 years. While it is generally recognized as a key enzyme in purine catabolism, its structural complexity and specialized tissue distribution suggest other functions that have never been fully identified. The publication, just over 20 years ago, of a hypothesis implicating XOR in ischemia-reperfusion injury focused research attention on the enzyme and its ability to generate reactive oxygen species (ROS). Since that time a great deal more information has been obtained concerning the tissue distribution, structure, and enzymology of XOR, particularly the human enzyme. XOR is subject to both pre- and post-translational control by a range of mechanisms in response to hormones, cytokines, and oxygen tension. Of special interest has been the finding that XOR can catalyze the reduction of nitrates and nitrites to nitric oxide (NO), acting as a source of both NO and peroxynitrite. The concept of a widely distributed and highly regulated enzyme capable of generating both ROS and NO is intriguing in both physiological and pathological contexts. The details of these recent findings, their pathophysiological implications, and the requirements for future research are addressed in this review.

  • Medical Policy Statement
    MEDICAL POLICY STATEMENT Effective Next Annual Last Review / Date Review Date Revision Date 06/15/2011 06/15/2012 06/15/2011 Author Shelley Jones RN, CCM, Wendy Null RPh CSMG Medical Policy Statements are derived from literature based and supported clinical guidelines, nationally recognized utilization and technology assessment guidelines, other medical management industry standards, and published MCO clinical policy guidelines. Medically necessary services are those health care services or supplies which are proper and necessary for the diagnosis or treatment of disease, illness, or injury and without which the patient can be expected to suffer prolonged, increased or new morbidity, impairment of function, dysfunction of a body organ or part or significant pain and discomfort. These services meet the standards of good medical practice in the local area, are the lowest cost alternative and are not provided mainly for the convenience of the member or provider. A. SUBJECT Alglucerase (Ceredase) Infusion B. BACKGROUND Alglucerase (Ceredase) is a modified form of the enzyme, ß-glucocerebrosidase (ß-D- glucosyl-N-acylsphingosine glucohydrolase). Alglucerase (Ceredase) catalyzes the hydrolysis of the glycolipid, glucocerebroside, to glucose and ceramide as part of the normal degradation pathway for membrane lipids. Glucocerebroside is primarily derived from hematologic cell turnover. Gaucher disease is characterized by a functional deficiency in ß-glucocerebrosidase enzymatic activity and the resultant accumulation of lipid glucocerebroside in tissue macrophages, which become engorged and are termed Gaucher cells. The patient selection criteria outlined was derived from the FDA-approved prescribing information for alglucerase (Ceredase), the studies that were presented to the FDA in support of the pre-market approval application, and studies in the peer-reviewed published medical literature.
