Reduction of <i>Ptf1a</i> Gene Dosage Causes Pancreatic Hypoplasia and Diabetes in Mice

Abstract excerpt

OBJECTIVE: Most pancreatic endocrine cells derive from Ptf1a-expressing progenitor cells. In humans, nonsense mutations in Ptf1a have recently been identified as a cause of permanent neonatal diabetes associated with pancreatic agenesis. The death of Ptf1a-null mice soon after birth has not allowed further insight into the pathogenesis of the disease; it is therefore unclear how much pancreatic endocrine function...
