Activation of phospholipase C beta 2 by the alpha and beta gamma subunits of trimeric GTP-binding protein [PDF]

open access: yes, 1993
Cotransfection assays were used to show that the members of the GTP-binding protein Gq class of alpha subunits could activate phospholipase C (PLC) beta 2.

Disruption of Vitamin D and Calcium Signaling in Keratinocytes Predisposes to Skin Cancer. [PDF]

open access: yes, 2016
1,25 dihydroxyvitamin D (1,25(OH)2D), the active metabolite of vitamin D, and calcium regulate epidermal differentiation. 1,25(OH)2D exerts its effects through the vitamin D receptor (VDR), a transcription factor in the nuclear hormone receptor family ...

Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

Post-heparin phospholipase

open access: yesJournal of Lipid Research, 1964
Egg phosphatidyl ethanolamine is degraded to lysophosphatidyl ethanolamine and fatty acids by a phospholipase in post-heparin plasma at rates of 10 to 30 μmoles/hr per ml plasma. The optimal system for measuring this enzyme contained albumin and (NH4)2SO4, and the optimal pH was 8.8–9.1.

Dysfunctional cardiac mitochondrial bioenergetic, lipidomic, and signaling in a murine model of Barth syndrome[S]

open access: yesJournal of Lipid Research, 2013
Barth syndrome is a complex metabolic disorder caused by mutations in the mitochondrial transacylase tafazzin. Recently, an inducible tafazzin shRNA knockdown mouse model was generated to deconvolute the complex bioenergetic phenotype of this disease. To

Secretory Phospholipase A2

open access: yesBiological and Pharmaceutical Bulletin, 2004
Secretory phospholipase A2 (sPLA2) is a growing family of structurally related, disulfide-rich, low molecular weight, lipolytic enzymes with a His-Asp catalytic dyad. sPLA2s are distributed in a wide variety of vertebrate and invertebrate animals, plants, bacteria, and viruses, and there are 10 catalytically active sPLA2 isozymes in mammals.

Assessing the Utility of Broad-Acting Inhibitors as Therapeutics in Diverse Venoms

open access: yesToxins
Examination of venom constituent bioactivities from diverse venomous animals shows certain highly conserved classes, including enzymes (e.g., phospholipases and metalloproteinases) and pore-forming proteins.

Plant phospholipid signaling: “in a nutshell”

open access: yesJournal of Lipid Research, 2009
Since the discovery of the phosphoinositide/phospholipase C (PI/PLC) system in animal systems, we know that phospholipids are much more then just structural components of biological membranes.

Growth Hormone Promotes Lipolysis and Impairs Insulin Sensitivity by Activating the ERK/HSL Signaling Pathway in Bovine Adipocytes

open access: yesAnimal Research and One Health, EarlyView.
This study was to evaluate the role of GH in lipolysis and insulin sensitivity in bovine adipocytes and clarify the underlying mechanism. Our findings demonstrate that GH activates ERK/HSL signaling pathway, promotes lipolysis, and impairs insulin sensitivity in bovine adipocytes.
