1. Identification of abnormally expressed genes in skeletal muscle contributing to insulin resistance and type 2 diabetes
Sammanfattning : The metabolic defects of insulin resistance and type 2 diabetes can result from changes in gene expression and protein functions due to genetic and environmental influences. The aim of this study was to identify abnormally expressed genes associated with insulin resistance or type 2 diabetes, and further to test whether possible defects are inherited or acquired. LÄS MER
2. Molecular Mechanism of Growth Hormone - Involvement of Janus Kinase 2, Insulin Receptor Substrate-1 and -2 and Phosphatidylinositol 3-Kinase In the Acute Insulin-Like Effects of Growth Hormone In Primary Rat Adipocytes
Sammanfattning : Originally studying the molecular mechanisms for the insulin-like effects of growth hormone (GH), lipogenesis and antilipolysis, in isolated rat adipocytes we found that the GH receptor (GHR) was tyrosine phosphorylated in response to GH in cells that were responsive to these effects. Then, as Janus kinase 2 (JAK2) was described as a GH-stimulated and GHR-associated tyrosine kinase, we found that JAK2 was tyrosine phosphorylated in response to GH in responsive cells. LÄS MER
3. Regulation of intracellular signaling events that modulate insulin action
Sammanfattning : Insulin regulates several mechanisms of fundamental importance to the body involving glucose, fat andprotein metabolism. Insulin resistance in skeletal muscle, liver and adipose tissue promotes an increaseddemand for insulin secretion. LÄS MER
4. Insulin signal transduction in skeletal muscle : special consideration for insulin resistance and diabetes
Sammanfattning : This dissertation work is focused on the insulin-signal-transduction pathways to glucose transport in skeletal muscle from animal models of NIDDM. The overall objective is to determine the effectiveness of different pharmacological treatments to improve insulin action in skeletal muscle. LÄS MER
5. Insulin-like growth factor-II : cellular effects through different receptors
Sammanfattning : Insulin-like growth factor-II (IGF-II) and IGF-I are single-chain polypeptides structurally homologous to proinsulin and share similarities with insulin in functional characteristics. Cellular actions of IGF-II are generally thought to be mediated through the IGF-I or insulin receptors, but not the IGF-II receptor, which is a single chain protein, identical to the cation independent mannose 6-phosphate (M6P) receptor and responsible for lysosomal enzyme targeting and degradation of IGF-II.
