Calcium in Renal Cells. Modulation of Calcium-dependent Activation of Phospholipase \(A_2\). [PDF]

open access: yes, 2011
Calcium has been implicated as a regulatory factor in many physiological and pathophysiological processes in the renal cell. Under physiological conditions, the cytosolic free calcium concentration is maintained at approximately 100 nM.

Lipid levels in sperm, eggs, and during fertilization in Xenopus laevis

open access: yesJournal of Lipid Research, 2008
Critical developmental periods, such as fertilization, involve metabolic activation, membrane fusion events such as sperm-egg or plasma membrane-cortical granule merger, and production and hydrolysis of phospholipids.

Study of the influence of various physiologically active substances on changes in the lipid composition and phospholipase activity of damaged somatic nerves [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Химия. Биология. Экология
The changes in lipid composition and phospholipase activity in damaged somatic nerves were studied against the background of the action of potassium hyaluronate and insulin-like growth factor-1.

Expression of mRNA for phospholipase A(2), cyclooxygenases, and lipoxygenases in cultured human umbilical vascular endothelial and smooth muscle cells and in biopsies from umbilical arteries and veins [PDF]

open access: yes, 1998
Arachidonic acid (AA) is released by phospholipase A(2) (PLA(2)) and then converted into vasoactive and inflammatory eicosanoids by cyclooxygenases (COX) and lipoxygenases (LOX).

Activation of phospholipase D-2 by P2X7 agonists in rat submandibular gland acini

open access: yesJournal of Lipid Research, 2002
Exogenous ATP stimulated phospholipase D (PLD), but not sphingomyelinase in rat submandibular gland (SMG) acini. PLD activation was dependent upon extracellular Ca2+ and did not involve intracellular Ca2+ mobilization or phosphoinositide-specific ...

The Interaction of Phospholipase C-{beta}3 with Shank2 Regulates mGluR-mediated Calcium Signal [PDF]

open access: yes, 2005
Phospholipase C-{beta} isozymes that are activated by G protein-coupled receptors (GPCR) and heterotrimeric G proteins carry a PSD-95/Dlg/ZO-1 (PDZ) domain binding motif at their C terminus. Through interactions with PDZ domains, this motif may endow the

Substrate-Specific Inhibition Constants for Phospholipase A2 Acting on Unique Phospholipid Substrates in Mixed Micelles and Membranes Using Lipidomics. [PDF]

open access: yes, 2019
Assaying lipolytic enzymes is extremely challenging because they act on water-insoluble lipid substrates, which are normally components of micelles, vesicles, and cellular membranes.

Lipid vesicle fusion induced by phospholipase C activity in model bile.

open access: yesJournal of Lipid Research, 1993
Using a system of phosphatidylcholine-cholesterol vesicles to model the vesicle phase of mammalian bile (1:1 molar ratio) we evaluated whether very small amounts of C.

Characterization of Clostridium perfringens isolated from mammals and birds from Guwahati city, India

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2012
Of the 102 samples collected from mammals and birds, both domestic and captive wild, 48 were found to be positive for Clostridium perfringens. Most of the mammal isolates (84.38%) appeared to have been collected from clinically affected animals, while 33.

Stimulation of a glycosyl-phosphatidylinositol-specific phospholipase by insulin and the sulfonylurea, glimepiride, in rat adipocytes depends on increased glucose transport [PDF]

open access: yes, 1994
. Lipoprotein lipase (LPL) and glycolipidanchored cAMP-binding ectoprotein (Gcel) are modified by glycosyl-phosphatidylinositol (GPI) in rat adipocytes, however, the linkage is potentially unstable. Incubation of the cells with either insulin (0.1-30 nM)
