  • Title: Pentagastrin stimulation of DNA synthesis and thymidine kinase activity in gastric mucosa of rats.
    Author: Majumdar AP.
    Journal: Horm Res; 1981; 15(1):37-43. PubMed ID: 7333572.
    Abstract:
    Following four equally spaced injections (at 12-hour intervals) of pentagastrin (250 microgram/kg) to fasted rats the incorporation of [3H]-thymidine into gastric mucosal DNA in vivo and in vitro was significantly increased by 30 and 58%, respectively, when compared with the corresponding saline control. Pentagastrin treatments also caused a significant 50% enhancement in gastric mucosal thymidine kinase activity. It is suggested that the hormone-mediated stimulation in thymidine kinase may, in part be due to the presence of a physiological activator for the enzyme in the tissue.
