Title: Glis3 regulates pancreatic beta cells development and maturation      
dateReleased:
07-01-2016
description:
Glis3 is expressed in pancreatic beta and PP cells. To identify down stream target genes of Glis3, we performed microarray analysis using pancreas total RNAs from 1 week-old WT and Glis3KO2 mice. insulin and pancreatic polypeptide (Ppy) was significantly decreased together with several other β cell markers, Glut2 and MafA by microarray analysis. Immunohistochemistry, QRT-PCR, and transmission electron microscopy indicated that postnatal Glis3KO2 pancreas still contains a large population of β cells that express Pdx-1, Nkx6.1, and Isl-1; however, insulin production and secretory granules were greatly reduced in these cells. In addition, chromogranin A (ChgA) and Urocortin 3, which are associated with mature β cells, was dramatically decreased in Glis3KO2 pancreas. These observations suggest that Glis3 plays a critical role in the maturation of pancreatic β cell phenotype. Pancreatic total RNAs were purified from 4 WT and 4 Glis3KO2 at 1 week old age. Then the samples were applied to Agilent mouse genome chip.
