  • The Effect of an Oral Or Intravenous Nucleotide-Free Diet on Selected Enzyme Activities in Purine Metabolism in Rats

B^fget Assistant Professor of Biochemistry Dr. George J. Æchfoépfer Professor of Biochemistry and Chemistry Dr. George'N. Bennett Assistant Professor of Biochemistry Dr. Roger L. Storck Professor of Biology HOUSTON, TEXAS MARCH, 1982 ABSTRACT THE EFFECT OF AN ORAL OR INTRAVENOUS NUCLEOTIDE-FREE DIET ON SELECTED ENZYME ACTIVITIES IN PURINE METABOLISM IN RATS SANDRA LYNN SNYDER Interrelationships between purine metabolism and immunity, cancer, and the diet have been considered. In studying trends of metabolic changes which occur in response to changes in the purine content of the diet, it has been hypothesized that when purines are lacking from the diet, there is a general shift from a catabolic to an anabolic state. In the present investigation, the activities of selected enzymes on purine metabolism in rats were studied with respect to an oral or intravenous nucleotide-free diet compared to the activities in rats fed normal chow. The intravenous nucleotide-free diet caused a decrease in purine nucleoside phosphorylase activity, an increase in adenine phosphoribosyl transferase, and no change in the activity of hypoxanthine-guanine phosphoribosyl transferase, with respect to a normal control diet. The orally fed nucleotide-free diet caused a decrease in the activity of purine nucleoside phosphorylase and xanthine oxidase and increase in pancreatic ribonucléase and no change in adenine phosphoribosyl transferase or hyphoxanthine-guanine phosphoribosyl transferase, with respect to a normal control diet.

However, the thought 0066-4219/08/0218-0177$20.00 that humans can undergo a severe hypometabolic state analogous to hibernation borders on science fiction. Some mammals can enter a severe hypothermic state during hibernation in which metabolic activity is extremely low, and yet full viability is restored when the animal arouses from such a state. To date, the underlying mecha- nism for hibernation or similar behaviors remains an enigma. The beneficial effect of hypothermia, which reduces cellular metabolic demands, has many well-established clinical applications. However, severe hypothermia induced by clinical drugs is extremely difficult and is associated with dramatically increased rates of cardiac arrest for nonhibernators. The recent discovery of a biomolecule, 5-AMP, which allows nonhibernating mammals to rapidly and safely enter severe hypothermia could remove this impediment and enable the wide adoption of hypothermia as a routine clinical tool. 177 ANRV334-ME59-12 ARI 16 December 2007 14:50 INTRODUCTION ing mammals.

  • Enhancing Nucleotide Metabolism Protects Against Mitochondrial Dysfunction and Neurodegeneration in a PINK1 Model of Parkinson’S Disease
    ARTICLES Enhancing nucleotide metabolism protects against mitochondrial dysfunction and neurodegeneration in a PINK1 model of Parkinson's disease Roberta Tufi1, Sonia Gandhi2, Inês P. de Castro1, Susann Lehmann1, Plamena R. Angelova2, David Dinsdale1, Emma Deas2, Hélène Plun-Favreau2, Pierluigi Nicotera3, Andrey Y. Abramov2, Anne E. Willis1, Giovanna R. Mallucci1, Samantha H. Y. Loh1,4 and L. Miguel Martins1,4 Mutations in PINK1 cause early-onset Parkinson's disease (PD). Studies in Drosophila melanogaster have highlighted mitochondrial dysfunction on loss of Pink1 as a central mechanism of PD pathogenesis. Here we show that global analysis of transcriptional changes in Drosophila pink1 mutants reveals an upregulation of genes involved in nucleotide metabolism, critical for neuronal mitochondrial DNA synthesis. These key transcriptional changes were also detected in brains of PD patients harbouring PINK1 mutations. We demonstrate that genetic enhancement of the nucleotide salvage pathway in neurons of pink1 mutant flies rescues mitochondrial impairment. In addition, pharmacological approaches enhancing nucleotide pools reduce mitochondrial dysfunction caused by Pink1 deficiency. We conclude that loss of Pink1 evokes the activation of a previously unidentified metabolic reprogramming pathway to increase nucleotide pools and promote mitochondrial biogenesis. We propose that targeting strategies enhancing nucleotide synthesis pathways may reverse mitochondrial dysfunction and rescue neurodegeneration in PD and, potentially, other diseases linked to mitochondrial impairment. The role of mitochondrial impairment in PD has long been debated. By combining transcriptional and metabolic profiling, we have Recently, the identification of causative mutations in PINK1, a gene uncovered significant alterations in the nucleotide metabolism encoding a mitochondrial kinase in PD patients has renewed interest in networks of pink1 mutant flies.

ABSTRACT Investigating metabolic rewiring in cancer can lead to the discovery of new treatment strategies for breast cancer subtypes that currently lack targeted therapies. Using MMTV- Myc driven tumors to model breast cancer heterogeneity, we investigated metabolic differences between two histological subtypes, the epithelial-mesenchymal transition (EMT) and the papillary subtypes, using a combination of genomic and metabolomic techniques. We identified differences in nucleotide metabolism between EMT and papillary subtypes: EMT tumors preferentially use the nucleotide salvage pathway, while papillary tumors prefer de novo nucleotide biosynthesis.

ABSTRACT Abnormal cancer metabolism occurs throughout the development of tumors. Recent studies have shown that abnormal nucleotide metabolism not only accelerates the development of tumors but also inhibits the normal immune response in the tumor microenvironment. Although few relevant experiments and reports are available, study of the interaction between nucleotide metabolism and cancer development is rapidly developing. The intervention, alteration or regulation of molecular mechanisms related to abnormal nucleotide metabolism in tumor cells has become a new idea and strategy for the treatment of tumors and prevention of recurrence and metastasis.

  • Development of a Genome-Scale Escherichia Coli Kinetic Metabolic Model Satisfying Flux Data for Multiple Mutant Strains
    Genomic Science Contractors–Grantees Meeting XIV and USDA‐DOE Plant Feedstock Genomics for Bioenergy Meeting, March 6-9, 2016 -- http://genomicscience.energy.gov/pubs/2016abstracts/ Development of a genome-scale Escherichia coli kinetic metabolic model satisfying flux data for multiple mutant strains Ali Khodayari ([email protected]) and Costas D. Maranas Department of Chemical Engineering, Pennsylvania State University, University Park, Pennsylvania, USA. http://www.maranasgroup.com Project Goals: The goal of this effort is to construct a genome-scale kinetic model of Escherichia coli metabolism by making use of Ensemble Modeling (EM) concepts. Model parameterization is carried out using multiple flux datasets for different substrates and growth (aerobic vs. anaerobic) conditions. Kinetic modeling paradigm provides a promising platform to broaden our knowledge of cellular capacity and cell physiology beyond stoichiometric descriptions. However, developing kinetic models of metabolism at a genome-scale that faithfully recapitulate the effect of multiple genetic interventions is still an ongoing challenge. To this end, we introduce k-ecoli457, a genome-scale kinetic model of Escherichia coli metabolism that satisfies fluxomic data for a wild-type and 25 mutant strains for different substrates and growth (aerobic vs. anaerobic) conditions. The k-ecoli457 model contains 457 reactions and 337 metabolites accounting for all relevant reactions from the genome-scale iAF1260 model that carry flux under the experimental conditions of the flux measurements. These include reactions in glycolysis/gluconeogenesis, the Pentose Phosphate (PP) pathway, the TriCarboxylic Acid (TCA) cycle, anaplerotic reactions, amino acid synthesis/degradation, fatty acid oxidation/synthesis and a number of reactions in other parts of the metabolism, such as folate metabolism, cofactor and prosthetic group synthesis, alternative carbon, membrane lipid, cell envelope, nucleotide salvage and oxidative phosphorylation pathways.
