  • Title: Adenine metabolism of Ehrlich mouse ascites cells in proliferating and resting phase of tumor growth.
    Author: Grune T, Siems W, Uhlig R, Jakstadt M.
    Journal: Biochem Int; 1992 Feb; 26(2):199-209. PubMed ID: 1558533.
    Abstract:
    The incorporation of 14C from [U-14C]adenine into the pools of purine nucleotides, nucleosides and bases in Ehrlich mouse ascites cells (EMAC1) during the proliferating and resting phases of tumor growth was compared. In the proliferating phase the total 14C incorporation into purine pools is much faster than in the resting phase. The ATP turnover as well as the purine breakdown to hypoxanthine and uric acid are increased in the proliferating phase. That corresponds to previous findings on higher nucleotide pool sizes and higher ATP yield and ATP-consuming processes in this growth period.
