- Rap1 activation plays a regulatory role in pancreatic amylase secretionMaria E Sabbatini
Department of Molecular and Integrative Physiology, University of Michigan, Ann Arbor, MI 48109 0622, USA
J Biol Chem 283:23884-94. 2008..Rap1 activation not only mediates the cAMP-evoked response via Epac1 but is also involved in CCK- and carbachol-induced amylase release, with their action most likely mediated by CalDAG-GEF III...
- Natriuretic peptides as regulatory mediators of secretory activity in the digestive systemMaria Eugenia Sabbatini
Department of Molecular and Integrative Physiology, University of Michigan, Ann Arbor, MI 48109 5622, United States
Regul Pept 154:5-15. 2009..Overall, these findings indicate that ANP and CNP are members of the large group of regulatory peptides affecting digestive secretions...
- CCK activates RhoA and Rac1 differentially through Galpha13 and Galphaq in mouse pancreatic aciniMaria E Sabbatini
Department of Molecular and Integrative Physiology, The University of Michigan, Ann Arbor, Michigan, USA
Am J Physiol Cell Physiol 298:C592-601. 2010..CCK-induced actin cytoskeletal reorganization is mainly mediated by Galpha(q). By contrast, Galpha(13) and Galpha(q) signaling are required for CCK-induced amylase secretion...
- Small G proteins as key regulators of pancreatic digestive enzyme secretionJohn A Williams
Dept of Molecular and Integrative Physiology, Univ of Michigan, Ann Arbor, MI 48109, USA
Am J Physiol Endocrinol Metab 296:E405-14. 2009..The Rho family small G proteins RhoA and Rac1 also regulate secretion through remodeling of the actin cytoskeleton. Possible mechanisms for regulation of these G proteins and their effector molecules are considered...
- Secretin is not necessary for exocrine pancreatic development and growth in miceMaria Dolors Sans
Department of Molecular and Integrative Physiology, University of Michigan, Ann Arbor, 48109 5622, USA
Am J Physiol Gastrointest Liver Physiol 301:G791-8. 2011..Camostat-fed littermate secretin and secretin receptor-deficient mice had similar pancreatic mass to WT mice. These results indicate that secretin is not required for normal pancreatic development or adaptive growth mediated by CCK...
