Transcription profiling of Foxa2 knock-outs in mice to better define the role of this gene in glucose homeostasis

Study to further characterize the genetic and functional consequence of the beta cell-specific ablation of Foxa2 (hepatocyte nuclear factor 3 beta, HNF-3b) in mice to better define the role of this gene in glucose homeostasis. The study involved 8 two-channel assays on UPenn Mouse PancChip 4.0, each consisting of a competitive mutant vs control hybridization. 4 control and 4 Foxa2loxP/loxP;Ins.CRE RNA samples were hybridized to the array using a dye-swap design. (The results from one of these assays had to be discarded from the analyses, so 7 assays were used.)
