(Submitter supplied) Aldosterone is known to have a number of direct adverse effects on the heart, including fibrosis and myocardial inflammation. However, genetic mechanisms of aldosterone action on the heart remain unclear. This experiment investigated of temporal changes in gene expression profile of the whole heart induced by acute administration of a physiologic dose of aldosterone in the mouse. mRNA levels of 34,000 known mouse genes were measured at eight time points after aldosterone administration using oligonucleotide microarrays and compared to those of the control animals who underwent a sham injection. more...

(Submitter supplied) Non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase (GAPN) is a conserved protein found in higher plants. In photosynthetic cells, the enzyme is involved in a shuttle transfer mechanism to export NADPH from the chloroplast to the cytosol. In this work, we demonstrate that GAPN gene express in leaves and roots at similar levels; showing the highest level of expression in flowers. To investigate the role of this enzyme in different plant tissues, we characterized a mutant from Arabidopsis thaliana having an insertion at the GAPN gene locus. more...

(Submitter supplied) Three major MAP kinase signaling cascades, ERK, p38 and JNK, play significant roles in the development of cardiac hypertrophy and heart failure in response to external stress and neural/hormonal stimuli. In order to study the specific function of each MAP kinase branch in adult heart, we have generated three transgenic mouse models with cardiac specific and temporally regulated expression of activated mutants of Ras, MKK3 and MKK7, which are selective upstream activators for ERK, p38 and JNK, respectively. more...

Analysis of adult hearts after induction of activated transgene mutants of Ras, MKK3, or MKK7, which are specific upstream activators of the MAP kinases ERK, p38, and JNK respectively. Hearts examined at various time points up to 4 weeks following each transgene induction using tamoxifen.

(Submitter supplied) We used high density oligonucleotide arrays to measure the relative expression levels of ~27,000 probe sets in the left ventricles of inbred rat strains; DA (high performing), Copenhagen (COP, low performing), as well as F1(COPxDA) rats bred from these two strains whose performance was intermediate relative to both parental strains. DA and COP rats differ for both intrinsic aerobic running capacity (assessed with a treadmill exercise test to exhaustion) and intrinsic cardiac performance (as assessed by the Langendorff-Neeley working heart model). more...

(Submitter supplied) Recent studies have highlighted the role of adrenal corticosteroid signaling in cardiac physiology and pathophysiology. It is known that glucocorticoids and aldosterone are able to bind glucocorticoid receptor (GR) and mineralocorticoid receptor (MR), and these ligand-receptor interactions are redundant. Therefore, it has been impossible to delineate how these nuclear receptors couple with corticosteroid ligands and differentially regulate gene expression for operation of their distinct functions in the heart. more...

(Submitter supplied) We have previously showed that whey protein hydrolysate (WPH) causes a greater increase in muscle protein synthesis than an identical composition of amino acids mixture does. The present study was conducted to investigate a comparative effect of WPH on gene expression. Male Sprague-Dawley rats subjected to a 2-h swimming exercise were administered either a carbohydrate-amino acid diet or a carbohydrate-WPH diet immediately after exercise. more...
