The Transcription Factor Rfx3 Regulates β-Cell Differentiation, Function, and Glucokinase Expression

Abstract excerpt

OBJECTIVE: Pancreatic islets of perinatal mice lacking the transcription factor Rfx3 exhibit a marked reduction in insulin-producing beta-cells. The objective of this work was to unravel the cellular and molecular mechanisms underlying this deficiency. RESEARCH DESIGN AND METHODS: Immunofluorescence studies and quantitative RT-PCR experiments were used to study the emergence of insulin-positive cells, the...
