Differential involvement of rat sperm choline glycerophospholipids and sphingomyelin in capacitation and the acrosomal reaction
(Elsevier France-editions Scientifiques Medicales Elsevier, 2010-12)
Rat spermatozoa main lipid classes and their fatty acids were studied to assess their possible changes in capacitation and the acrosomal reaction (AR), induced in vitro . Capacitation-associated protein tyrosine phosphorylation, ...
LC-ESI-MS/MS Method for the profiling of glycerophospholipids and its application to the analysis of tobacco hairy roots as early indicators of phenol pollution
(Vieweg, 2021-04)
The growing impact of organic and inorganic pollutants on the environment has led to the development of numerous strategies to counteract this effect. Among all, green technologies such as phytoremediation, has won relevance ...
Impact of phenol on the glycerophospholipid turnover and potential role of circadian clock in the plant response against this pollutant in tobacco hairy roots
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-06)
Glycerophospholipids (GPLs) from cell membranes (CM) are a proper source for the synthesis of lipid messengers able to activate signal pathways that will define the plant survival under changing and stressful environmental ...
Lipid composition of purified transverse tubule membranes isolated from amphibian skeletal muscle
(1987)
The level and proportion of lipids and their fatty acid composition were analyzed in highly purified transverse tubule membranes of amphibian skeletal muscle. Tubule membranes show (a) a higher content of lipids, (b) a ...
Mitochondrial acyltransferases and glycerophospholipid metabolism
(Elsevier Science, 2017-01)
Our understanding of the synthesis and remodeling of mitochondrial phospholipids remains incomplete. Two isoforms of glycerol-3-phosphate acyltransferase (GPAT1 and 2) and two isoforms of acylglycerol-3-phosphate acyltransferase ...
Choline Glycerophospholipid-Derived Prostaglandins Attenuate TNFα Gene Expression in Macrophages via a cPLA2α/COX-1 Pathway
(MDPI, 2021-02)
Macrophages are professional antigen presenting cells with intense phagocytic activity, strategically distributed in tissues and cavities. These cells are capable of responding to a wide variety of innate inflammatory ...
Daily rhythms of glycerophospholipid synthesis in fibroblast cultures involve differential enzyme contributions
(American Society for Biochemistry and Molecular Biology, 2013-05-02)
Circadian clocks regulate the temporal organization of several biochemical processes including lipid metabolism and their disruption leads to severe metabolic disorders. Immortalized cell lines acting as circadian clocks ...
Do Subjective Alcohol Screening Tools Correlate with Biomarkers Among High-Risk Transgender Women and Men Who Have Sex with Men in Lima, Peru?
(Springer, 2017)
Alcohol abuse can influence sexual risk behavior; however, its measurement is not straightforward. This study compared self-reported alcohol use, via the AUDIT and CAGE, with levels of phosphatidylethanol (Peth), a ...
Influence of Ca2+ on the surface behavior of phosphatidic acid and its mixture with diacylglycerol pyrophosphate at different pHs
(Elsevier Ireland, 2020-05)
The signaling lipids phosphatidic acid (PA) and diacylglycerol pyrophosphate (DGPP) are involved in regulating the stress response in plants. PA and DGPP are anionic lipids consisting of a negatively charged phosphomonoester ...
