Alterations in the transmembrane gradients of several physiological ions may influence programmed cell death. In particular, recent data suggest that increases in intracellular calcium may either promote or inhibit apoptosis, depending on the level, timing and location, whereas loss of intracellular potassium promotes apoptosis.

Genetics of ion homeostasis in Ménière’s Disease
European Archives of Oto-Rhino-Laryngology, 2016Aim of this work was to assess the role of polymorphisms belonging to genes involved in the regulation of ionic homeostasis in Caucasian patients with Ménière Disease (MD). We recruited 155 patients with definite Ménière Disease and 186 controls (Control Group 1) without a lifetime history of vertigo, overlapping with patients for age and rate of ...

Abstract Hepatic encephalopathy (HE) is a neuropsychiatric disorder associated with acute and chronic liver failure. Ammonium is the most likely toxin responsible for the observed neurological deficits, reaching 5 mM in the CNS during acute HE. Additionally, ammonium preferentially affects astrocytes.

ABSTRACTThe constant composition of body fluids in insects is maintained by the cooperative interaction of gastrointestinal and urinary tissues. Water follows ionic movements, which are driven by the basolateral Na+/K+-ATPase and/or the apical ‘K+(or Na+) pump’.

Brain ion homeostasis in cerebral ischemia
Neurochemical Pathology, 1988Brain function is severely disturbed in ischemia. Within seconds, consciousness and spontaneous activity is lost, whereas interstitial concentrations of major ions are kept near normal levels. After a few minutes, there is a dramatic increase of potassium and a lowering of sodium, chloride, and calcium concentrations. Similar ionic changes are observed

Disruption of Ion Homeostasis by Verrucosin and a Related Compound
Bioscience, Biotechnology and Biochemistry, 2011 We have found that (-)-virgatusin and related compounds have antimicrobial and antifungal activity. To identify further biological activities of these compounds, we tested the activity of acridine orange efflux, which shows ionophore-like disruption of cellular ion homeostasis activity. After testing 31 compounds, we found that verrucosin and a related

Metal ion homeostasis in Bacillus subtilis
Current Opinion in Microbiology, 2005Bacillus subtilis, a Gram-positive soil bacterium, provides a model system for the study of metal ion homeostasis. Metalloregulatory proteins serve as the arbiters of metal ion sufficiency and regulate the expression of metal homeostasis pathways. In B.

Calcium ion homeostasis in smooth muscle
Pharmacology & Therapeutics, 1992Ca2+ plays an important role in the regulation of smooth-muscle contraction. In this review, we will focus on the various Ca(2+)-transport processes that contribute to the cytosolic Ca2+ concentration. Mainly the functional aspects will be covered.

Metal ion homeostasis and intracellular parasitism
Molecular Microbiology, 1998Bacteria possess multiple mechanisms for the transport of metal ions. While many of these systems may have evolved in the first instance to resist the detrimental effects of toxic environmental heavy metals, they have since become adapted to a variety of important homeostatic functions.

Ion homeostasis during salt stress in plants
Current Opinion in Cell Biology, 2001Recent progress has been made in the characterization of cation transporters that maintain ion homeostasis during salt stress in plants. Sodium-proton antiporters at the vacuolar (NHX1) and plasma membrane (SOS1) have been identified in Arabidopsis. SOS1 is regulated by the calcium-activated protein kinase complex SOS2-SOS3.
