Project description:Ablation of the mouse gene for Onecut-2 was reported previously, but characterization of the resulting knockout mice was focused on in utero development, principally embryonic development of liver and pancreas. Here, we examine postnatal development of these Onecut-2 knockout mice, especially the critical period prior to weaning. Microarray technology was used to determine the effect of Onecut-2 ablation on gene expression in duodenum, whose epithelium has among the highest levels of Onecut-2. A subset of intestinally expressed genes showed dramatically altered patterns of expression. Many of these genes encode proteins associated with the epithelial membrane, including many involved in transport and metabolism. Previously, we reported that Onecut-2 was critical to temporal regulation of the adenosine deaminase gene in duodenum. Many of the genes with altered patterns of expression in the Onecut-2 knockout mouse duodenum displayed changes in the timing of gene expression. Duodenal segments were isolated at postnatal days 15 and 30 from wild type 129 mice and 129 mice with the Onecut-2 gene ablated . Total RNA was isolated in biological triplicate for each experimental time point. Each triplicate contained RNA from 5-8 mice of the appropriate age and genotype. Affymetrix microarray technology was used to compare gene expression in wild type duodenum at d15 to gene expression in wild type duodenum at d30 and to compare gene expression in duodenum from Onecut-2 knockout mice at d15 and d30 to each other and to the expression in wild type duodenum.

Project description:Tamoxifen-inducible conditional knockout (CKO) mice were generated to explore the function of Gcn1 in adult mice using the Cre/loxP system. To analyze the function of GCN1 in the intestinal epithelium, we compared the whole cell proteome of duodenum harvested from GCN1 CKO mice with that of wild-type mice.
Project description:Bulk RNA expression profiles were captured from hearts of alpha7 nicotinic acetylcholine receptor (Chrna7) knockout (KO) and wild type (WT) mice that underwent myocardial infarction (MI) or sham (SH) surgery at postnatal day 1 and full ventricle collection at 7 days post-surgery
Project description:Bulk RNA expression profiles were captured from hearts of Leucine-rich repeat containing protein 10 (Lrrc10) knockout (KO) and wild type (WT) mice that underwent myocardial infarction (MI) or sham (SH) surgery at postnatal day 1 and full ventricle collection at 7 days post-surgery
Project description:Combinatorial ablation of the major cardiac-expressed novel protein kinase C isoforms, PKCdelta and PKCepsilon, in murine cadiac myocytes unmasked functionally redundant growth-limiting effects of these kinases in hemodynamically stressed adult hearts and during normal embryonic cardiac development, mediated in part by shared transcriptional de-repression of ERK and periostin signaling. 14 cardiac polyA+-RNA profiles from unstressed, 12 week-old C57BL/6J-background mice (4 wild-type, 3 postnatal cardiac PKCdelta ablation, 3 germline PKCepsilon knockout, 4 combined knockouts) and 15 profiles generated 4 weeks after TAC induction (4 wild-type, 3 PKCdelta, 4 PKCepsilon, 4 combined knockout) were generated on Illumina HiSeq 2000 instruments.
