1. 6. Studies of Budding Yeast Transcription Factors Acting Downstream of Nutrient Signaling Pathways

   Författare :Niklas Nordberg; Hans Ronne; Anders Blomberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budding yeast; nutrient signaling; glucose repression; aging; caloric restriction; JmjC; histone demethylation; Mig1; Mig2; Mig3; Gis1; Rph1; Molekylär genetik; Molecular Genetics;

   Sammanfattning : Being able to respond to extracellular cues such as nutrients and growth factors is of vital importance to all living cells. Pathways have therefore evolved which can sense the extracellular status, transmit a signal through the cell and affect gene expression, which ultimately enables adaptation. LÄS MER

3. 7. β-adrenergic regulation of glucose transporters

   Författare :Olof Dallner; Tore Bengtsson; Jeffrey Pessin; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenergic receptors; glucose transporters; Physiology; Fysiologi; fysiologi; Physiology;

   Sammanfattning : The transport of glucose across the plasma membrane is a fundamental mechanism to provide cells with its basic requirements for energy yielding processes. It is also vital for clearing glucose from blood into tissues, a process normally stimulated by the hormone insulin in mammals. LÄS MER

4. 8. Effects of Orexins, Guanylins and Feeding on Duodenal Bicarbonate Secretion and Enterocyte Intracellular Signaling

   Författare :Magnus Wilhelm Bengtsson; Gunnar Flemström; Olof Nylander; Karl E. O. Åkerman; Per M. Hellström; Uppsala universitet; []
   Nyckelord :Physiology; alkaline secretion; carbohydrates; central nervous system; cholinergic stimulation; duodenum; enteric nervous system; enterochromaffin cell; fasting; feeding; glucose; guanylyl cyclase C; humans; hypocretin; intra-arterial; in situ; intracerebroventricular; luminal acid; luzindole; orexin-B; SB-334867; Fysiologi;

   Sammanfattning : The duodenal epithelium secretes bicarbonate ions and this is regarded as the primary defence mechanism against the acid discharged from the stomach. For an efficient protection, the duodenum must also function as a sensory organ identifying luminal factors. LÄS MER

5. 9. The Role of Hexose Transport on Glycolytic Flux and Glucose Induced Responses in Saccharomyces cerevisiae

   Författare :Karin Elbing; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glucose signaling; metabolic control; Snf1; glycolysis; Mig1; Hexose transport; Yeast; Saccharomyces cerevisiae;

   Sammanfattning : In the yeast Saccharomyces cerevisiae, glucose is primarily fermented rather than respired. Only in cultivation modes such as chemostats or fed-batches, where the external glucose is kept low, a fully respiratory catabolism is observed. LÄS MER

7. 10. Glucose and insulin modulate phagocytosis and production of reactive oxygen metabolites in human neutrophil granulocytes

   Författare :Daniel Saiepour; Per-Arne Oldenborg; Janove Sehlin; Olle Stendahl; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophil granulocytes; glucose; insulin; protein kinase C; diacylglycerol; phagocytosis; respiratory burst; diabetes; Histology; Histologi;

   Sammanfattning : Neutrophil granulocytes play an important role in the host defence against invading microorganisms and constitute the frontline of defence within the innate immune system and are among the first cells to arrive at the site of inflammation. Effective phagocytosis and killing of invading pathogens by neutrophils is of significant importance for successful resistance to infectious diseases. LÄS MER
