1. 1. Unraveling Mechanisms of Insulin Resistance in Type 2 Diabetes in Human Adipocytes : Role of extracellular signal regulated kinase 1/2 (ERK1/2) and forkhead box protein 01 (FOX01)

   Författare :Meenu Rohini Rajan; Peter Strålfors; Mats Söderström; Olga Göransson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Type 2 Diabetes is characterized by hyperglycemia primarily caused due to insulin resistance in insulin responsive tissues and insufficient production of insulin by the β-cells. Insulin resistance appears to develop first in the expanding adipose tissue during caloric surplus and affects other tissues like liver and muscle by ectopic fat accumulation. LÄS MER

3. 2. 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.

4. 3. Macrophage Activation and AP-1 in Atherosclerosis

   Författare :Maria Stollenwerk; Kardiovaskulär forskning - immunitet och ateroskleros; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Proteins; enzymology; Proteiner; enzymologi; Cardiovascular system; carotid plaque; interleukin-1b; caspase-1.; very low-density lipoprotein; fatty acids; activator protein-1; inflammation; Atherosclerosis; nuclear factor-kB; macrophages; tumor necrosis factor;

   Sammanfattning : High levels of very low density lipoprotein (VLDL) and intermediate density lipoprotein (IDL) have been identified as independent risk factors for coronary heart disease. Hypertriglyceridemia is generally associated with an increased expression of inflammatory makers and inflammation is thought to contribute to atherosclerosis and its complications. LÄS MER

5. 4. Notch Signaling in Neuroblastoma and Renal Cell Carcinoma

   Författare :Jonas Sjölund; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; differentiation; clear cell renal cell carcinoma; neuroblastoma; TGF-beta; migration; γ-secretase; valproic acid; cancer; Notch; ERK; von Hippel-Lindau; hypoxia;

   Sammanfattning : The Notch signaling pathway governs cell functions essential for normal development and organogenesis. Aberrant Notch signaling has been implicated in tumorigenesis by perturbing control of proliferation, differentiation, apoptosis, migration and angiogenesis. LÄS MER

7. 5. MEKK-1 and NF-κB Signaling in Pancreatic Islet Cell Death

   Författare :Dariush Mokhtari; Nils Welsh; Michael Welsh; Anders Tengholm; Shanta Persaud; Uppsala universitet; []
   Nyckelord :Cell biology; MEKK-1; JNK; human islets; β-cells; siRNA; apoptosis; cell death; MAPK; nitric oxide; cytokines; streptozotocin; c-Rel; NF-κB; Cellbiologi;

   Sammanfattning : Type 1 diabetes is an autoimmune disease resulting in the selective destruction of the insulin producing β-cells in the pancreas. Pro-inflammatory cytokines and the free radical nitric oxide (NO) have been implicated in mediating the destruction of β-cells, possibly through activation of the mitogen activated protein kinases (MAPKs) JNK, ERK and p38.
