The role of Stl1p in glycerol accumulation in osmotically stressed icewine yeast Saccharomyces cerevisiae K1 V1116
… high sugar concentration in Icewine juice exerts hyperosmotic stress in the wine yeast causing water loss and cell shrinkage. To counteract the dehydration, yeast synthesize and accumulate glycerol as an internal osmolyte. In a laboratory strain of S. cerevisiae, STLl encodes for Stllp, an H+ …

S100A4 regulation and function
… by integrin α6β4 in breast cancer cells, and hyperosmotic stress response in colon cancer cells, as well as the functional aspects of S100A4 in these two models. Using breast cancer cell lines, I found that S100A4 is upregulated by integrin α6β4 and its expression correlates well with integrin …

Regulation of Protein Turnover during Hyper-osmotic Stress in Skeletal Muscle
… study was to examine the effect of hyper-osmotic stress on protein turnover in skeletal muscle tissue using an established in-vitro model. Rat EDL muscles were incubated in either hyper-osmotic (400 ± 10 Osm) or isoosmotic (290 ± 10 Osm) custom-modified media (Gibco). L-[14C]-U-phenylalanine (n=8) …

Determining the Roles of the Aldehyde Dehydrogenase Enzymes 5 and 6 during Icewine and Table Wine Fermentation in a Commercial Wine Yeast Using CRISPR-Cas9.
… high sugar juice environment (40°Brix) causes hyperosmotic stress for yeast, resulting in water loss, triggering glycerol production to act as an internal osmolyte to draw water back into the yeast cell, resulting in an NAD+ imbalance. Icewine has significantly higher acetic acid versus table …

Dilution acidosis : the effects of hyperosmolality on acid-base balance and ventilation
… changes in these variables. Studies in acute hyperosmotic stress were therefore undertaken to investigate both the nature of the acid-base disturbance and the implications for ventilatory control. 31P nuclear magnetic resonance spectroscopy (31P NMR) on duck pectoral muscle showed that the …

Investigating the regulation of tumour associated lipogenesis using the model organism, Saccharomyces cerevisiae
… of Saccharomyces cerevisiae cells to respond to stress conditions, primarily hyperosmotic stress. In addition, there is also evidence that the HOG pathway is involved in lipid accumulation, which occurs in nitrogen depleted cells as they enter stationary phase. Understanding this lipogenic switch …

Molecular analysis of the responses of Caenorhabditis elegans (Bristol N2), Panagrolaimus rigidus (AF36) and Panagrolaimus sp. (PS 1579) (Nematoda) to water stress
… and genetic analysis of the responses to water stress in desiccation-tolerant and desiccation-sensitive nematodes. Caenorhabditis elegans, a model organism for the study of development, aging, and cell biology was shown to be a desiccation-sensitive organism that survives relative humidities …

Glycerol from novel strains of halophytic microalgae
… in Dunaliella cells exposed to salinity stress under continuous light or dark regimes. (c) Maximize glycerol recovery from microalgal cultures using novel supercritical carbon dioxide (SC-CO2) extraction technology. Dunaliella and Asteromonas strains were shown to withstand large …

Hyperosmolality effects on growth and morphology of CHO cells
… diluted in the volume of large cells exposed to hyperosmotic stress. We also detected a significant decrease in mitochondrial membrane potential, a key parameter correlating with mitochondrial fitness and ATP production capacity, if the exposure to harsh mannitol hyperosmolality (530 mOsm/kg) and …

Development and application of a microfluidic platform for single-cell cultivation of CHO suspension cell lines
… to identify cellular heterogeneity in hyperosmotic stress response of CHO cells, to quantify the migratory behavior of human cardiac stem cells under different cultivation conditions, and to analyze cell cycle progression and cell cycle heterogeneity in CHO cells. Here, investigating …
