Insulin Action on Polyunsaturated Phosphatidic Acid Formation in Rat Brain: An “In Vitro” Model with Synaptic Endings from Cerebral Cortex and Hippocampus [PDF]

open access: yes, 2009
The highly efficient formation of phosphatidic acid from exogenous 1-stearoyl-2-arachidonoyl-sn-glycerol (SAG) in rat brain synaptic nerve endings (synaptosomes) from cerebral cortex and hippocampus is reported.

Snake Venom Hemotoxic Enzymes: Biochemical Comparison between Crotalus Species from Central Mexico

open access: yesMolecules, 2019
Snakebite envenoming is a serious medical problem in different areas of the world. In Latin America, the major prevalence is due to snakes of the family Viperidae, where rattlesnakes (Crotalus) are included.

Action of phospholipase A2 and phospholipase C on Escherichia coli

open access: yesArchives of Biochemistry and Biophysics, 1974
The action of exogenous phospholipases on Escherichia coli has been examined. Cells harvested in late log phase were found to be completely resistant to the action of phospholipases A2 and C. Treatment of cells with Tris and EDTA was required to make the phospholipids in the cell accessible to these phospholipases.

Inhibitory effect of curcumin on mammalian phospholipase D activity [PDF]

open access: yes, 1997
Curcumin, the major yellow pigment of turmeric (Curcuma longa), has strong anti-carcinogenic and anti-inflammatory activities. We examined the effects of curcumin on enzyme activities of the following phospholipases in a cell-free system: G protein ...

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.

Antitumoral Potential of Tunisian Snake Venoms Secreted Phospholipases A2

open access: yesBioMed Research International, 2013
Phospholipases type A2 (PLA2s) are the most abundant proteins found in Viperidae snake venom. They are quite fascinating from both a biological and structural point of view.

Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

open access: yesAnimal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

open access: yesBMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Use of LC‐MS to characterize host cell protein removal during depth filtration

open access: yesBiotechnology Progress, EarlyView.
Abstract The removal of host cell proteins (HCPs) is crucial in biopharmaceutical production, as residual impurities can impact product safety and efficacy. While a number of studies have demonstrated that depth filtration can provide significant HCP removal, there is little information on its effectiveness in removing specific HCPs.
