6. 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
7. The functional roles of the intra-oocyte phosphatidylinositol 3-kinase (PI3K) signaling in controlling follicular development in mice
Sammanfattning : The key functions of the mammalian ovary are the production of fertilizable oocytes and thesecretion of steroid hormones. At the time of birth the human ovary is composed of basic unitstermed primordial follicles. Primordial follicles are long-lived structures in the ovary and some ofthem last until the woman reaches menopause. LÄS MER
8. The role of phosphatidylinositol 4-phosphate 5-kinase type І alpha (PIP5K1α) and utility of its inhibitor for targeting metastatic cancer
Sammanfattning : Prostate cancer (PCa) is the most common cause of cancer-related death in men after lung cancer. Annually, more than 9000 new cases are diagnosed in Sweden and 2500 of them die each year. Metastatic prostate cancer can be treated with castration. LÄS MER
9. Molecular mechanisms of insulin action in human skeletal muscle and adipose tissue : implications for diabetes and obesity
Sammanfattning : Studies of animal models of type 2 diabetes mellitus implicate that impaired insulin signal transduction to glucose transport accounts for whole body insulin resistance in skeletal muscle and adipose tissue. The overall aim of the present thesis was to determine insulin signal transduction to glucose transport in human skeletal muscle and adipose tissue from type 2 diabetic patients and obese insulin resistant subjects.

10. Effect of hyperglycemia on glucose transport and intracellular signal transduction in skeletal muscle
Sammanfattning : Recent studies revealing the components of insulin signal transduction have raised the question of whether the defects in insulin signaling account for disturbed glucose metabolism in people with NIDDM. The major focus of this thesis is to elucidate the role of insulin signal transduction in the development of peripheral insulin resistance. LÄS MER
