Project description:To identify the target genes of glucokinase activator (GKA) in islet, GKA-induced gene expression in mouse pancreatic islets was measured at 24 hours after treatment of 30 microM GKA or vehicle. GKA-induced gene expression in mouse pancreatic islets was measured at 24 hours after treatment of 30 microM GKA or vehicle.

Project description:The zinc finger factor Insm1 is known to regulate differentiation of pancreatic ? cells during development, Here we show that Insm1 is essential for the maintenance of functionally mature pancreatic ? cells in mice. We used microarrays to analyse the global gene expression after deletion of insm1 in adult pancreatic ? cells and identified functional important genes and immature islets releated genes deregulated in the mutatant islets. We used 8 mutant and 8 litter matched control mice for the islets preparation.
Project description:Nkx6.1 target genes were identified in mature pancreatic islets by comparing gene expression in conditional Nkx6.1-ablated islets versus control islets using microarray analysis.
Project description:Intrauterine growth restriction is a common complication of pregnancy. We induce IUGR in rats by bilateral uterine artery ligation at e18 of a 23 day gestation. This mimics placental insufficiency. This array experiment compares gene expression changes in isolated pancreatic islets from e19, 24 hours post-surgery , or sham operated animals. RNA from isolated pancreatic islets from e19 fetuses, pooled from an entire litter. There are 4 control (sham) operated litters and 4 IUGR litters.
Project description:To gain insights into how pancreatic cells are programmed in vivo, we profiled RNA expression in pancreatic islets of pancreatic Ring1b conditional KO mice (conditional using a pancreas specfic Cre; Pdx1-Cre) and their littermate controls
Project description:To gain insights into how pancreatic cells are programmed in vivo, we profiled Ring1b in embryonic stem cells and pancreatic islets
