  • Title: Nucleotide pool and the proliferative process: an NMR study of the liver regeneration.
    Author: Baldassarri AM, Giomini M, Giuliani AM, Trotta E, Boicelli CA.
    Journal: Physiol Chem Phys Med NMR; 1987; 19(2):95-100. PubMed ID: 3432376.
    Abstract:
    The metabolic changes occurring during liver regeneration after partial hepatectomy have been followed by examination of the perchloric extracts by means of NMR spectroscopy. Proton spectra show an abrupt decrease of glycogen, glucose and nucleotides, which are essentially ribonucleotides, in the first hours after hepatectomy. Nucleotides begin to store up again in the third day after hepatectomy, while glucose and glycogen storage builds up from the second day. 31P data evidence a sharp drop of phosphomonoesters, i.e. monophosphosugars (including AMP) and phosphocholine, and phosphodiesters, i.e. GPC and GPE, soon after hepatectomy and a recovery of the initial levels approximately at the 60th hour and a further increase of PDE at later times. The NMR findings are in agreement with the biochemical knowledge of the course of liver regeneration.
