Mammalian renal inner medullary cells are normally exposed to extremely high NaCl concentrations. The interstitial NaCl concentration in parts of a normal renal medulla can be 500 mM or more, depending on the species. Remarkably, under these normal conditions, the high NaCl causes DNA damage, yet the cells survive and function both in cell culture and ...

miR-429 regulation of osmotic stress transcription factor 1 (OSTF1) in tilapia during osmotic stress
Biochemical and Biophysical Research Communications, 2012The Nile tilapia represents an excellent model for osmoregulation study. Osmotic stress transcription factor 1 (OSTF1) identified in tilapia gill epithelium is a critical element of osmosensory signal transduction by means of transcriptional regulation. Thus, tight regulation of OSTF1 level is necessary for tilapia osmotic adaptation. microRNAs (miRNAs)

Spermatozoal response to osmotic stress
Animal Reproduction Science, 2005The process of sperm cryopreservation imparts on sperm cells the stress of low-temperature and drastic osmotic change. Damage to the cell plasma membrane results in cell injury in a number of cellular structures and associated functions. Studies in the author's laboratory have focused upon the various mechanisms of osmotic and thermal injury including ...

Osmotic stress adaptations in rhizobacteria
Journal of Basic Microbiology, 2012AbstractRhizobacteria have been reported to be beneficial to the plants in many different ways. Increasing salinity in the coastal agricultural zones has been shown to be a threat to the plant and microbial life in the area. Exposure of microorganisms to high‐osmolality environments triggers rapid fluxes of cell water along the osmotic gradient out of ...

Erythrocytes under osmotic stress – modeling considerations
Progress in Biophysics and Molecular Biology, 2015Various modeling approaches have been applied to describe structural changes of the erythrocyte constituents under osmotic stress. The constituents: (1) the lipid bilayer, (2) the actin-spectrin cortex, (3) the trans-membrane protein band 3, (4) the intracellular hemoglobin contribute to the relaxation phenomenon. Cells response includes the successive

Soft matter under osmotic stress
Polymer, 2001Abstract In this article, we will show that the osmotic stress method can be successfully applied to study the thermodynamics of self-assembly phenomena in soft matter systems, such as biopolymer liquid crystals, surfactant and lipid mesophases, and polyelectrolyte–surfactant complexes. We will give two examples to that effect.

Transient osmotic stress facilitates mutant huntingtin aggregation
NeuroReport, 2002Human neuroblastoma SH-SY5Y cell lines stably expressing mutant truncated huntingtin with 82 (mutant) glutamine repeats (N63-82Q) were briefly exposed to hyperosmotic conditions which decrease cell volume and therefore transiently increased the concentration of N63-82Q, as well as activating specific stress-induced pathways.

Osmotic stress activates phosphatidylinositol-3,5-bisphosphate synthesis
Nature, 1997Inositol phospholipids play multiple roles in cell signalling systems. Two widespread eukaryotic phosphoinositide-based signal transduction mechanisms, phosphoinositidase C-catalysed phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2) hydrolysis and 3-OH kinase-catalysed PtdIns(4,5)P2 phosphorylation, make the second messengers inositol 1,4,5 ...

Osmotic stress sensing and signaling in fishes
The FEBS Journal, 2007In their aqueous habitats, fish are exposed to a wide range of osmotic conditions and differ in their abilities to respond adaptively to these variations in salinity. Fish species that inhabit environments characterized by significant salinity fluctuation (intertidal zone, estuaries, salt lakes, etc.) are euryhaline and able to adapt to osmotic stress.

Wet-Spinning of Osmotically Stressed Silk Fibroin
Biomacromolecules, 2009Based on the phase diagram constructed for water-silk fibroin-LiBr using the osmotic stress method, wet-spinning of osmotically stressed, regenerated Bombyx mori silk fibroin was performed, without the necessity of using expensive or toxic organic solvents.
