Osmotic shock or osmotic stress is physiologic dysfunction caused by a sudden change in the solute concentration around a cell, which causes a rapid change in the movement of water across its cell membrane.

Osmotic shock or osmotic stress is physiological dysfunction induced by a sudden shift in solvent concentration across a cell that induces a rapid change in water flow through the cell membrane (Finan and Guilak, 2010).

Osmotic stress is a potent regulator of the normal function of cells that are exposed to osmotically active environments under physiologic or pathologic conditions. The ability of cells to alter gene expression and metabolic activity in response to ...

2023年10月16日 · During osmotic shock, cell volume changed dramatically within tens of seconds (Fig. 2b), making it difficult to measure cortical tension directly and dynamically.

Osmotic shock destabilizes SH3 in cells. The increase in the concentration of macromolecules caused by the osmotic-stress-induced decrease in cellular volume increases hard-core interactions.

2002年11月14日 · Osmotic shock is a familiar means for rupturing viral capsids and exposing their genomes intact. The necessary conditions for providing this shock involve incubation in high-concentration salt solutions, and lower permeability of the …

The osmotic stress or osmotic shock is the sudden undesirable changes in the solute concentrations inside the cells, which are mostly the results of drought or salinity/salt stress. Both the drought and salinity stress activates multiple signaling cascade, that …

Osmotic stress induces nucleotide salvage, and the biosynthesis of glutamate, lysine, and peptidoglycan, but represses genes associated with fatty acid production for inclusion in the cell membrane. The heat shock gene, dnaK, is induced, as is the stringent response.

2024年3月21日 · Osmotic shock and enzymes: One way to lyse cells is by lowering the ionic strength of the medium the cells are in. This can cause cells to swell and burst. Mild surfactants may be used to disrupt membranes.

Gaining insight into osmotic pressure and its biological implications is pivotal for revealing mechanisms underlying numerous fundamental biological processes across scales and will contribute to the biomedical and pharmaceutical fields. This review ...
