Description
Diabetes mellitus results from an inadequately functioning beta-cell mass. In the adult pancreas, beta-cell mass is dynamic, increasing to meet metabolic demands and decreasing with metabolic or injury insults. Exendin-4 (Ex-4) is a glucagon-like peptide-1 receptor agonist that augments beta-cell mass by increasing beta-cell neogenesis and proliferation and by reducing apoptosis. We utilized a cDNA microarray approach to identify genes that are differentially regulated during islet growth after Ex-4 treatment or a partial pancreatectomy (Ppx). Mice underwent 50% Ppx or sham operation and received Ex-4 or vehicle every 24 hours. cDNA prepared from total pancreatic RNA isolated at 12, 24 and 48 hrs after surgery was hybridized to the PancChip 4.0 microarray.
