Biochemical Evidence for a Putative Inositol 1,3,4,5-Tetrakisphosphate Receptor in the Olfactory System of Atlantic Salmon (Salmo salar).

Neuroscience journal

Olfactory receptor neurons in Atlantic salmon (Salmo salar) appear to use a phosphoinositide-directed phospholipase C (PLC) in odorant signal transduction. The consequences of odor-activated PLC depend on its product, inositol 1,4,5-trisphosphate (IP3). Therefore, a plasma membrane rich (PMR) fraction,...

In this study we have analysed the effects of ethanol and divalent cations on the binding of [(3) H]-inositol 1,4,5 trisphosphate to rat cerebellar membranes. Rats were injected intraperitoneally, daily, with 3g of ethanol/kg of body weight for different...

Front Mol Neurosci. 2013 Nov 05;6:36. doi: 10.3389/fnmol.2013.00036. eCollection 2013.

Dysregulation of Ca(2+) homeostasis is considered to contribute to the toxic action of the Alzheimer's disease (AD)-associated amyloid-β-peptide (Aβ). Ca(2+) fluxes across the plasma membrane and release from intracellular stores have both been reported to underlie the Ca(2+) fluxes...

Ethanol stimulates phospholipid turnover and inositol 1,4,5-trisphosphate production in Chlamydomonas eugametos gametes.

Planta. 1992 Feb;186(3):442-9. doi: 10.1007/BF00195326.

Alcohols induce mating-structure activation in Chlamydomonas eugametos gametes. From the effect of ethanol on the (32)P-labelling of polyphosphoinositides, we conclude that the synthesis of these lipids is stimulated. Biologically inactive concentrations of ethanol (

-Altered Ca(2+) handling is observed in different cells in essential hypertension. We investigated the expression of sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA) and inositol 1,4,5-trisphosphate receptor (IP(3)R) isoforms in platelets and aortic endothelial cells (EC) isolated from spontaneously hypertensive (SHR) and...

Methods for the synthesis of 3-O-(carboxymethyl)- and 3-O-alkylated myo-inositol 1,4,5-trisphosphates in racemic form from myo-inositol have been devised. For DL-3-O-(carboxymethyl)-myo-inositol 1,4,5-trisphosphate, an analogue of myo-inositol 1,3,4,5-tetrakisphosphate, DL-3-O-allyl-2,6-di-O-benzyl-1-O-(p-methoxybenzyl)-4,5-O-isopropylidene-myo-inositol (14) was prepared from myo-inositol in seven steps. The triol DL-3-O-allyl-2,6-di-O-benzyl-myo-inositol (26),...

Endothelin Induces a Rise of Inositol 1,4,5-Trisphosphate, Inositol 1,3,4,5-Tetrakisphosphate Levels and of Cytosolic Ca2+ Activity in Neural Cell Lines.

The mechanism of action of the vasoconstricting peptide endothelin was investigated in two neural cell lines. In rat glioma cells endothelin-1 caused a biphasic rise in cytosolic Ca2+ activity. A large peak of 40 s duration was followed by...

Mastoparan-Induced Intracellular Ca2+ Fluxes May Regulate Cell-to-Cell Communication in Plants.

The relationship of Ca2+ and plasmodesmatal closure was examined in staminal hairs of Setcreasea purpurea by microinjecting cells with active mastoparan (Mas-7), inactive mastoparan (Mas-17), active inositol-1,4,5-trisphosphate (IP3), or inactive IP3. Calcium green dextran 10,000 was used to study...

Second messenger-controlled membrane conductance in locust (Locusta migratoria) olfactory neurons.

Metabolism of the putative messenger molecule d-myo-inositol(1,4,5)trisphosphate [Ins(1,4,5)P(3)] in plant cells has been studied using a soluble fraction from pea (Pisum sativum) roots as enzyme source and [5-(32)P]Ins(1,4,5)P(3) and [2-(3)H]Ins(1,4,5)P(3) as tracers. Ins(1,4,5)P(3) was rapidly converted into both lower...
