Transport of Sugars.

Transport of Sugars. Annu Rev Biochem. 2015 Mar 5; Authors: Chen LQ, Cheung LS, Feng L, Tanner W, Frommer WB Abstract Soluble sugars serve five main purposes in multicellular organisms: as sources of carbon skeletons, osmolytes, signals, and transient energy storage and as transport molecules. Most sugars are derived from photosynthetic organisms, particularly plants. In multicellular organisms, some cells specialize in providing sugars to other cells (e.g., intestinal and liver cells in animals, photosynthetic cells in plants), whereas others depend completely on an external supply (e.g., brain cells, roots and seeds). This cellular exchange of sugars requires transport proteins to mediate uptake or release from cells or subcellular compartments. Thus, not surprisingly, sugar transport is critical for plants, animals, and humans. At present, three classes of eukaryotic sugar transporters have been characterized, namely the glucose transporters (GLUTs), sodium-glucose symporters (SGLTs), and SWEETs. This review presents the history and state of the art of sugar transporter research, covering genetics, biochemistry, and physiology-from their identification and characterization to their structure, function, and physiology. In humans, understanding sugar transport has therapeutic importance (e.g., addressing diabetes or limiting access of cancer cells to sugars), and in plants, these transporters are critical for crop yield and pathogen susceptibility. Expe...

In conclusion, it remains unclear if brain-specific regional and temporal changes occur in the expression of the different APP variants during AD progression. Since APP is also found in blood cells, assessing the changes in APP mRNA expression in peripheral blood cells from AD patients has been considering an alternative. However, again the quantification of APP mRNA in peripheral blood cells has generated controversial results. Brain APP protein has been analyzed in only a few studies, probably as it is difficult to interpret the complex pattern of APP variants and fragments. We previously characterized the soluabl...

AbstractAngiogenesis plays a key role in the pathology of diseases such as cancer, diabetic retinopathy, and age-related macular degeneration. Understanding the driving forces of endothelial cell migration and organization, as well as the time frame of these processes, can elucidate mechanisms of action of important pathological pathways. Herein, we have developed an organ-specific microfluidic platform recapitulating the in vivo angiogenic microenvironment by co-culturing mouse primary brain endothelial cells with brain pericytes in a three-dimensional (3D) collagen scaffold. As a proof of concept, we show that this model...

Calorie restriction lowers body temperature in mammals, but most research on how reduced calorie intake produces benefits to long-term health and longevity has focused on nutrient sensing as the primary trigger for the upregulation of stress responses and other helpful changes to cellular metabolism. Here, researchers demonstrate that reduced body temperature is in fact an important trigger mechanism, possible more so than nutrient sensing, as keeping calorie restricted mice warm eliminates much of the beneficial metabolic adaptation to reduced nutrient levels. Cutting calories significantly may not be an easy tas...

This study is the first to provide a direct link between this inflammation and plaque development - by way of IFITM3. Scientists know that the production of IFITM3 starts in response to activation of the immune system by invading viruses and bacteria. These observations, combined with the new findings that IFITM3 directly contributes to plaque formation, suggest that viral and bacterial infections could increase the risk of Alzheimer's disease development. Indeed, researchers found that the level of IFITM3 in human brain samples correlated with levels of certain viral infections as well as with gamma-secretase activ...

Basel, 11 September 2020 – Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced new data that show OCREVUS® (ocrelizumab) is a highly effective treatment option for people with relapsing-remitting multiple sclerosis (RRMS) who experienced a suboptimal response to their prior disease modifying therapy (DMT). Subgroup analys is from the two-year open-label Phase IIIb CASTING study also demonstrates that patients benefit across a wide range of disease related and demographic subgroups, regardless of prior treatment background. Findings will be presented at MSVirtual2020, the 8th Joint Meeting of the Americas Committee...

In conclusion, using a large cohort with rich health and DNA methylation data, we provide the first comparison of six major epigenetic measures of biological ageing with respect to their associations with leading causes of mortality and disease burden. DNAm GrimAge outperformed the other measures in its associations with disease data and associated clinical traits. This may suggest that predicting mortality, rather than age or homeostatic characteristics, may be more informative for common disease prediction. Thus, proteomic-based methods (as utilised by DNAm GrimAge) using large, physiologically diverse protein sets for p...
