Abstract:
It is the aim of the study to unravel the role of Notch signaling in pancreatic development and during acute pancreatitis using pancreas-specific Notch1 knockout (N1KO) mice utilizing the Cre/loxP system. Expression analyses revealed a reduction of Notch1 expression in N1KO pancreata of 91 %. Examination of embryonic, juvenile and adult pancreata revealed no significant impact of Notch1 signaling on pancreatogenesis. After induction of pancreatitis, the initial destruction of the acinar compartment was comparable in wt and Notch deficient mice. However, regeneration was significantly delayed in Notch deficient mice. The results implicate an important role of Notch1 signaling in the restitution of a balanced and physiologic homeostasis in disease states of the pancreas, and a negligible role in the genesis and maintenance of a physiologic homeostasis.
