Effects of selective phosphodiesterase type IV inhibitor, rolipram, on signal transducing phospholipases in neutrophil: Inhibition of phospholipases A2, D but not C

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1995
The effects of a selective phosphodiesterase (PDE) type IV inhibitor, rolipram, on activation of neutrophil phospholipases in response to the chemotactic peptide formyl-methiony-leucyl-phenylalanine (fMLP) were investigated. fMLP caused liberation of arachidonic acid, a precursor of eicosanoids and in the presence of 0.3% butanol, production of ...

The Promoter Activity of the Phospholipase C-γ2 Gene Is Regulated by a Cell-Type-Specific Control Element

DNA and Cell Biology, 1997
We have cloned and characterized a genomic DNA spanning the 5'-flanking region, the first and second exons, and the first intron of the human PLC-gamma2 gene. The proximal upstream region is highly GC-rich and lacks a TATA box, whereas the distal region contains several AT-rich tracts.

Multifunctional activity of the extracellular domain of the M-type (180 kDa) membrane receptor for secretory phospholipases A2.

Biochemistry, 1995
M-type (180 kDa) receptors for secretory phospholipases A2 (sPLA2s) are thought to mediate some of the physiological effects of group I sPLA2, including smooth muscle contraction and cell proliferation.

Studies on phosphatidylinositol phosphodiesterase (phospholipase C type) of Bacillus cereus

Archives of Biochemistry and Biophysics, 1978
Abstract A phosphatidylinositol-specific phospholipase C (PIase), purified 447-fold from the culture broth of Bacillus cereus by ammonium sulfate precipitation and chromatography with CM-Sephadex and DEAE-cellulose, was analyzed in vitro and in vivo for its activity to induce the release of alkaline phosphatase from plasma membrane.

Phospholipase and Aspartyl Proteinase Activities of Candida Species Causing Vulvovaginal Candidiasis in Patients with Type 2 Diabetes Mellitus.

Journal of Microbiology and Biotechnology, 2015
Few research had investigated the secretion of phospholipase and aspartyl proteinase from Candida spp. causing infection in females with type 2 diabetes mellitus.

Significance of nuclear phospholipase C signaling through type 1 IGF receptor.

Journal of endocrinological investigation, 2004
The existence of a nuclear polyphosphoinositol metabolism independent from that at the plasma membrane is now widely recognized. Specific changes in the nuclear phosphatidylinositol (Ptdlns) metabolism have been implicated in cell growth, differentiation, and neoplastic transformation.

Volume-sensitive chloride current in pigmented ciliary epithelial cells: role of phospholipases.

American Journal of Physiology, 1997
The whole cell recording technique was used to examine an outwardly rectifying chloride current activated by hypotonic shock in bovine pigmented ciliary epithelial (PCE) cells.

Identification of a new high-affinity binding protein for neurotoxic phospholipases A2.

Biochemical and Biophysical Research Communications - BBRC, 1998
Ammodytoxin C is a neurotoxic phospholipase A2 which blocks the release of neurotransmitter from the nerve terminal. Using a radioiodinated derivative of the toxin, we located its specific high-affinity binding site in the demyelinated P2 fraction of ...

Expression of Angiotensin II Type-I Receptor and Phospholipase C-Linked Gαq/11 Protein in the Human Placenta

Journal of the Society for Gynecologic Investigation, 1996
A recent study on the distribution of angiotensin II (ANG II), ANG II (AT) receptors, and human placental lactogen in human placental tissues from term pregnancies showed positive correlations among these indices, suggesting an important role for ANG II in placental endocrinology.

Mammalian secreted phospholipases A2 and their pathophysiological significance in inflammatory diseases.

Current molecular medicine, 2001
Phospholipases A2 (PLA2s) represent a growing family of enzymes that catalyze the hydrolysis of phospholipids at the sn-2 position leading to the generation of free fatty acids and lysophospholipids.
