Metabolic Tracing of NAD Precursors Using Strategically Labelled Isotopes of NMN
A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Metabolic tracing of NAD+ precursors using strategically labelled isotopes of NMN by Lynn-Jee Kim Supervisors Dr. Lindsay E.

NAD+ declines with biological ageing and in age-related diseases such as diabetes and strategies to restore intracellular NAD+ levels are emerging as a promising strategy to protect against metabolic dysfunction, treat age-related conditions and promote healthspan and longevity. One of the most effective ways to increase NAD+ is through pharmacological supplementation with NAD+ precursors such as nicotinamide mononucleotide (NMN) which can be orally delivered. Long term administration of NMN in mice mitigates age-related physiological decline and alleviates the pathophysiologies associated with a high fat diet- and age-induced diabetes. Despite such efforts, there are certain aspects of NMN metabolism that are poorly understood. In this thesis, the mechanisms involved in the utilisation and transport of orally administered NMN were investigated using strategically labelled isotopes of NMN and mass spectrometry. -

IUBMB Newsletter Issue 2.Pdf
IUBMB NEWS Issue 2 October 2016 President’s Message IUBMB aims to promote research and education in In This Issue Biochemistry and Molecular Biology. In this regard, over the President’s Message years we have channelled great efforts into the research aspects of our science. We now consider it timely to turn our Report on the 16th IUBMB attention to educational initiatives. Conference / Young To address this aim and in collaboration with FEBS, we are organising a conference on Education in Biochemistry and Molecular Biology, to be held in Scientists’ Program Rehovot (Israel) in September 2017. The conference seeks to provide a think-tank Tang Prize Foundation setting in which to draw up ideas to improve the current approach to teaching these subjects, and to generate a series of recommendations to be shared with Awardees / IUBMB Travel the educational community. In this regard, this conference will serve to propel the Fellowships changes that are required to bring education in biochemistry and molecular biology st at all levels into the 21 century. Another Way to Think About Another important aspect of education is to provide young scientists from Disease by Gregory Petsko developing countries the opportunity to attend international congresses and meetings. IUBMB is firmly committed to this endeavour and devotes significant Retrospective — financial resources to this end. Given that the number of applications from African countries is very low, I wish to encourage our young African colleagues to apply Osamu Hayaishi and benefit from IUBMB travel awards and Wood-Whelan fellowships. An Appreciation — IUBMB is also launching a new activity, namely Focused Meetings. -

Etzler, University of California, Davis he sugar chains of cells—known collectively as glycans—play a variety of impressive, critical, and often Tsurprising roles in biological systems. Glycobiology is the study of the roles of glycans in the growth and development, function, and survival of an organism. Glyco-related processes, described in vivid detail in the text, have become increasingly significant in many areas of basic research as well as biomedicine and biotechnology. This new edition of Essentials of Glycobiology covers the general principles and describes the structure and biosynthesis, diversity, and function of glycans and their relevance to both normal physiologic processes and human disease. Several new chapters present significant advances that have occurred since the publication of the first edition. Three sections of note describe organismal diversity, advances in our understanding of disease states and related therapeutic applications, and the genomic view of glycobiology. “Glycomics,” analogous to genomics and proteomics, is the systematic study of all glycan structures of a given cell type or organism and paves the way for a more thorough understanding of the functions of these ubiquitous molecules. -
