1. 1. Adipocyte phosphatases and the antilipolytic action of insulin

   Författare :Svante Resjö; Signaltransduktionsforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein phosphorylation; protein purification; adipose tissue; PP2A; protein phosphatase; PDE3B; phosphodiesterase 3B; Insulin signalling; antilipolysis; Klinisk biologi; Clinical biology; PKB; protein kinase B;

   Sammanfattning : Adipose tissue is the main site of energy storage of the body and an important endocrine organ. Knowledge of the regulation of fat metabolism and the endocrine factors secreted by the adipocyte is crucial for the understanding of diseases such as obesity and diabetes. Insulin is the main antilipolytic hormone. LÄS MER

3. 2. Insulin Signalling and Regulation of Protein Kinase B in Adipocytes

   Författare :Olga Göransson; Proteinfosforylering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; Endokrinologi; sekretion; diabetologi; secreting systems; Endocrinology; PDK1; PKB; diabetes; insulin; adipocyte;

   Sammanfattning : Insulin resistance is a hallmark of type 2 diabetes, an increasingly common disorder. The cause of insulin resistance is supposedly failures in the processes used by insulin to signal to the interior of its target cells. These failing steps are still unknown, most probably because of incomplete knowledge of how the insulin signals are transmitted. LÄS MER

4. 3. Protein kinases in hormonal regulation of adipocyte metabolism

   Författare :Christine Berggreen; Proteinfosforylering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipocyte; PKB; AMPK; SIK3; insulin; catecholamines; lipolysis; lipogenesis; glucose uptake; de novo fatty acid synthesis; A769662; Akti; cAMP;

   Sammanfattning : Abstract Along with liver and muscle tissue, adipose tissue helps maintain normal levels of glucose and lipids in the blood and has a very important role when it comes to storing lipids that can provide whole-body energy. After a meal is ingested, adipocytes take up glucose from the circulation and use it as a substrate for synthesis of new fatty acids (FAs) in a process known as de novo fatty acid synthesis, as well as for synthesis of glycerol.

5. 4. Studies on Cell Injury Induced by Hypoxia-Reoxygenation and Oxidized Low Density Lipoprotein : With Special Reference to the Protectiove Effect of Mixed Tocopherols, Omega-3 Fatty Acids and Transforming Growth Factor-beta1

   Författare :Hongjiang Chen; Tom Saldeen; Christer Sylven; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Tocopherols; fish oil; TGF-β1; NOS; adhesion molecules; MMPs; PKB; MAPK; H-R; Ox-LDL; Myocytes; HCAECs; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

   Sammanfattning : Hypoxia-reoxygenation (H-R) injury is an important clinical phenomenon in patients with coronary artery disease (CAD). Endothelial injury is a critical step in the initiation and progression of atherosclerosis. Therefore, endothelial and cardiomyocyte protection has been considered an effective step in prevention and treatment of CAD. LÄS MER

7. 5. The mechanism of integrin inactivation and cell signalling induced by c-erbB2, an oncogenic growth factor receptor

   Författare :Shahram Hedjazifar; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c-erbB2; integrin á2â1; cell-matrix; integrin conformation; PKB; ERK; Rho; ILK; Nck-2;

   Sammanfattning : Overexpression of the oncogenic growth factor receptor, c-erbB2, is linked with poor prognosis in breast carcinomas and is used as a target for therapeutic strategies. To elucidate the mechanism underlying the tumorigenic action of an elevated c-erbB2 level, leading to homodimerization and activation, we have used an inducible system where a hybrid receptor consisting of the cytoplasmic and transmembrane domains of c-erbB2 fused to the extracellular domain of the trkA NGF receptor has been stably transfected into an immortalized mammary epithelial cell line.
