Inflammatory response and cytokine elaboration are particularly active after myocardial infarction and contribute to cardiac remodeling and eventual host outcome. The triggers of cytokine release in the acute postinfarction period include mechanical deformation, ischemic stimulus, reactive oxygen species (ROS), and cytokine self-amplification pathways.(More)
O besity and associated type 2 diabetes mellitus are the emerging epidemic of this new century. Identifying the key mechanism of the pathophysiology offers unique insights into potential prevention and therapy. One of the classic animal models of obesity and insulin resistance has been the ob/ob mouse. Zhang et al 1 set the scientific world a-buzz in 1994(More)
Cellular FLICE-inhibitory protein (cFLIP) is a member of the tumour necrosis factor signalling pathway and a regulator of apoptosis, and it has a role in cardiac remodelling following myocardial infarction (MI) that remains largely uncharacterised. This study aimed to determine the function of cFLIP as a potential mediator of post-infarction cardiac(More)
The glucagon-like peptides (GLPs) are synthesized and secreted in a nutrient-dependent manner in rodents; however, the factors regulating human GLP-1 and GLP-2 biosynthesis remain unclear. To understand how nutrients regulate human proglucagon gene expression, we studied the expression of a human proglucagon promoter-growth hormone (GH) transgene in 1.6(More)
A single mammalian proglucagon gene is expressed in the brain, islets, and intestinal enteroendocrine cells, which gives rise to a unique profile of proglucagon-derived peptides (PGDPs) in each tissue. The biological importance of glucagon, glucagon-like peptide (GLP)-1, and GLP-2 has engendered considerable interest in the factors regulating the synthesis(More)
The mammalian proglucagon gene is expressed in pancreatic islet A-cells, intestinal L-cells, and select neurons of the brain, where posttranslational processing results in the liberation of a unique profile of peptides. Despite the importance of proglucagon-derived peptides in human biology, little is known about the regulation of the human gene, as the rat(More)
Glucagon-like peptides 1 and 2 (GLP-1 and GLP-2) are coencoded within a single mammalian proglucagon precursor, and are liberated in the intestine and brain. GLP-1 exerts well known actions on islet hormone secretion, gastric emptying, and food intake. Recent studies suggest GLP-1 plays a central role in the development and organization of islet cells.(More)
