2. 1. Studies of penta-decameric binding proteins: AP-4 and CBF-A

   Author : Alaitz Aranburu; Immunologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; transplantation; Metabolism; serologi; metabolism; Biokemi; serology; Immunology; hnRNP H; NPM; CBF-A; AP-4; transcription; B cells; immunoglobulin; Immunologi;

   Abstract : Each immunoglobulin (Ig) V gene segment contains an upstream promoter region. The octamer element and the TATA box are the only elements that are conserved in all Ig promoters. The presence of the octamer element is necessary, but not sufficient to support high levels of transcription. READ MORE

4. 2. Links between plasma apoE and glucose metabolism, brain insulin signaling, and synaptic integrity : Relevance to Alzheimer’s disease pathophysiology

   Author : Anna Edlund; Henrietta Nielsen; William Rebeck; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; apolipoprotein E; insulin; metabolism; Amyloid precursor protein APP ; Fe65; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Abstract : Human apolipoprotein E (apoE) exists as three main isoforms called apoE2, apoE3, and apoE4, of which the E4 isoform is associated with increased Alzheimer’s disease (AD) risk. Brain glucose hypometabolism, linked to synaptic dysfunction, occurs years before symptom onset in AD, especially in APOEε4-carriers. READ MORE

5. 3. Novel methods to study mitochondrial gene expression and homeostasis

   Author : Magdalena Rzepka; Martin Ott; Christof Osman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mitochondria; gene expression; metabolism; biokemi; Biochemistry;

   Abstract : Mitochondria are semi-autonomous organelles that harbor one of the main cellular processes – energy conversion. Nutrients available in the environment are taken up by cells and transformed into metabolites that can be used for synthesis of ATP, the energy currency of the cell. READ MORE

6. 4. To “leaf” or not to “leaf” : Understanding the metabolic adjustments associated with leaf senescence

   Author : Daria Chrobok; Olivier Keech; Per Gardeström; David Macherel; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; metabolism; mitochondria; senescence; biology; biologi;

   Abstract : The adequate execution of the final developmental stage of a leaf, leaf senescence, is crucial to the long-term survival of the plant. During senescence cellular structures like membranes, proteins, lipids and macromolecules are degraded and released nutrients are relocated to developing parts of the plant, such as young leaves, stems, flowers, siliques and ultimately seeds that are dependent on this nutrient remobilization.

7. 5. Interaction of Triglyceride-rich Lipoproteins with Platelets and Vitamin K-dependent Coagulation Factors

   Author : Ning Xu; Avdelningen för klinisk kemi och farmakologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Triglycerides.; Prothrombin; Protein S; Protein C; Platelets; Phospholipids; Metabolism; Lipoproteins; Lipids; Endocytosis; Electron microscopy; Cytochemistry; Coronary heart disease; Blood coagulation factors; Arachidonic acid; Atherosclerosis; Clinical chemistry; Klinisk kemi; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

   Abstract : 1. During incubation of platelets with 3H-arachidonic acid (20:4, n-6) and 14C-cholesterol doubly labelled and colloidal gold labelled chylomicrons (CMs) and chylomicron remnants (CMRs) CMs were taken up more efficiently than CMRs. Addition of unlabelled CMs, VLDLs, LDLs and HDLs decreased the uptake of labelled CMs. READ MORE
