Cell volume regulation: osmolytes, osmolyte transport, and signal transduction.
In recent years, it has become evident that the volume of a given cell is an important factor not only in defining its intracellular osmolality and its shape, but also in defining other cellular functions, such as transepithelial transport, cell migration, cell growth, cell death, and the regulation of intracellular metabolism. In addition, besides inorganic osmolytes, the existence of organic ...
متن کاملVolume-sensitive release of organic osmolytes in the human lung epithelial cell line A549: role of the 5-lipoxygenase.
Pathophysiological conditions challenge cell volume homeostasis and perturb cell volume regulatory mechanisms leading to alterations of cell metabolism, active transepithelial transport, cell migration, and death. We report that inhibition of the 5-lipoxygenase (5-LO) with AA861 or ETH 615-139, the cysteinyl leukotriene 1 receptor (CysLT₁) with the antiasthmatic drug Zafirlukast, or the volume-...
متن کاملHuman sperm volume regulation. Response to physiological changes in osmolality, channel blockers and potential sperm osmolytes.
BACKGROUND Volume regulation is an important sperm function because defective sperm cannot negotiate the female tract in an infertile mouse model and swollen human sperm cannot penetrate and migrate through mucus. METHODS AND RESULTS The size of sperm from 52 donor ejaculates incubated in medium of female tract fluid osmolality (BWW290) was measured by flow cytometry to be identical to that i...
متن کاملRole of Organic Osmolytes in Myelinolysis
Introduction Organic osmolytes have been implicated in the pathogenesis of myelinolysis because some of them are accumulated slowly during correction of chronic hyponatremia. I investigated whether there was a topographic correlation between demyelinative lesions and the regional changes of organic osmolytes after rapid correction of chronic hyponatremia. In normal female Sprague-Dawley rats, c...
متن کاملHuman trabecular meshwork cell volume regulation.
The volume of certain subpopulations of trabecular meshwork (TM) cells may modify outflow resistance of aqueous humor, thereby altering intraocular pressure. This study examines the contribution that Na+/H+, Cl-/HCO exchange, and K+-Cl- efflux mechanisms have on the volume of TM cells. Volume, Cl- currents, and intracellular Ca2+ activity of cultured human TM cells were studied with calcein flu...
