The aim of this study was to determine whether the opening of the osmolyte channel in skate red blood cells (RBC) is regulated by intracellular electrolyte concentration and conductivity. Consistent with previous studies, experiments with hyperosmotic preincubation before cell swelling or swelling with an isosmotic electrolyte (e.g., ammonium chloride) showed that an increase in ionic strength ...
Organic osmolytes, such as taurine, are involved in cell volume homeostasis and cell protection. Epidermal keratinocytes possess an osmolyte strategy, i.e., they take up taurine upon hyperosmotic stress and express the corresponding transporter TAUT. UVB irradiation also triggers taurine uptake and TAUT expression in this cell type. We therefore asked whether taurine plays a role in photoprotec...
We examined the physiological significance of the nuclear versus cytosolic localization of the MAPK Hog1p in the ability of yeast cells to cope with osmotic and ER (endoplasmic reticulum) stress. Our results indicate that nuclear import of Hog1p is not critical for osmoadaptation. Plasma membrane-anchored Hog1p is still able to induce increased expression of GPD1 and glycerol accumulation. This...
