Description:
Nuclear magnetic resonance (NMR) spectroscopy is useful to determine molecular structure in tissues grown in vitro only if their fidelity, relative to native tissue, can be established. Here, we use multidimensional NMR spectra of animal and in vitro model tissues as fingerprints of their respective molecular structures, allowing us to compare the intact tissues at atomic length scales. To obtain spectra from animal tissues, we developed a heavy mouse enriched by about 20% in the NMR-active isotopes carbon-13 and nitrogen-15. The resulting spectra allowed us to refine an in vitro model of developing bone and to probe its detailed structure. The identification of an unexpected molecule, poly(adenosine diphosphate ribose), that may be implicated in calcification of the bone matrix, illustrates the analytical power of this approach.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chow, W Ying -- Rajan, Rakesh -- Muller, Karin H -- Reid, David G -- Skepper, Jeremy N -- Wong, Wai Ching -- Brooks, Roger A -- Green, Maggie -- Bihan, Dominique -- Farndale, Richard W -- Slatter, David A -- Shanahan, Catherine M -- Duer, Melinda J -- BB/G021392/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0500707/Medical Research Council/United Kingdom -- PG/08/011/24416/British Heart Foundation/United Kingdom -- PG/10/43/28390/British Heart Foundation/United Kingdom -- RG/09/003/27122/British Heart Foundation/United Kingdom -- RG/11/14/29056/British Heart Foundation/United Kingdom -- New York, N.Y. -- Science. 2014 May 16;344(6185):742-6. doi: 10.1126/science.1248167.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Cambridge, Lensfield Road, Cambridge CB2 1EW, UK. ; Orthopaedic Research Unit, University of Cambridge, Addenbrooke's Hospital, Cambridge CB2 0QQ, UK. ; Department of Physiology, Development, and Neuroscience, University of Cambridge, Downing Site, Cambridge CB2 3DY, UK. ; Central Biomedical Resources, University of Cambridge, School of Clinical Medicine, West Forvie Building, Forvie Site, Robinson Way, Cambridge CB2 0SZ, UK. ; Department of Biochemistry, University of Cambridge, Downing Site, Cambridge CB2 1QW, UK. ; British Heart Foundation Centre of Research Excellence, Cardiovascular Division, James Black Centre, King's College London, 125 Coldharbour Lane, London SE5 9NU, UK. ; Department of Chemistry, University of Cambridge, Lensfield Road, Cambridge CB2 1EW, UK. mjd13@cam.ac.uk.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24833391" target="_blank"〉PubMed〈/a〉
