Chiaki Murakami et al.
Analytical biochemistry, 526, 43-49 (2017-03-21)
Phosphatidylcholine (PC)-specific phospholipase C (PC-PLC) hydrolyzes PC to generate the second messenger 1,2-diacylglycerol (DG) and phosphocholine. PC-PLC plays pivotal roles in inflammation, carcinogenesis, tumor progression, atherogenesis, and subarachnoid hemorrhage. Although the activity of PC-PLC in mammalian tissues was discovered approximately
Manuele Piccolis et al.
Molecular cell, 74(1), 32-44 (2019-03-09)
Excessive levels of saturated fatty acids are toxic to cells, although the basis for this lipotoxicity remains incompletely understood. Here, we analyzed the transcriptome, lipidome, and genetic interactions of human leukemia cells exposed to palmitate. Palmitate treatment increased saturated glycerolipids

Metabolites, 10(7) (2020-07-28)
Typical lipidomics methods incorporate a liquid-liquid extraction with LC-MS quantitation; however, the classic sample extraction methods are not high-throughput and do not perform well at extracting the full range of lipids especially, the relatively polar species (e.g., acyl-carnitines and glycosphingolipids).
Luciana Mercedes Pujol-Lereis et al.
Journal of insect physiology, 87, 53-62 (2016-02-13)
The remodeling of membrane composition by changes in phospholipid head groups and fatty acids (FA) degree of unsaturation has been associated with the maintenance of membrane homeostasis under stress conditions. Overall lipid levels and the composition of cuticle lipids also
Rosa Chillemi et al.
European journal of medicinal chemistry, 96, 467-481 (2015-05-02)
Resveratrol, a polyphenol present in grapes and other edible plants, possesses several important pharmacological activities, including anticancer activity. Nevertheless, its therapeutic use is still limited because of some unfavourable physicochemical and pharmacokinetic properties, mainly, poor cellular uptake and too rapid
Michael Zick et al.
Molecular biology of the cell, 24(23), 3746-3753 (2013-10-04)
The fusion of yeast vacuolar membranes depends on the disassembly of cis-soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complexes and the subsequent reassembly of new SNARE complexes in trans. The disassembly of cis-SNARE complexes by Sec17/Sec18p releases the soluble SNARE
Hongki Song et al.
eLife, 9 (2020-01-22)
Yeast vacuole fusion requires R-SNARE, Q-SNAREs, and HOPS. A HOPS SM-family subunit binds the R- and Qa-SNAREs. We now report that HOPS binds each of the four SNAREs. HOPS catalyzes fusion when the Q-SNAREs are not pre-assembled, ushering them into
Takashi Watanabe et al.
Journal of lipid research, 58(12), 2334-2347 (2017-10-14)
Thraustochytrids are marine single-cell protists that produce large amounts of PUFAs, such as DHA. They accumulate PUFAs in lipid droplets (LDs), mainly as constituent(s) of triacylglycerol (TG). We identified a novel protein in the LD fraction of
Chang Li et al.
Journal of agricultural and food chemistry, 63(44), 9850-9854 (2015-10-20)
The capacities of six antioxidants to inhibit the formation of 3-monochloropropane-1,2 diol (3-MCPD) esters were examined in this study. Inhibitory capacities of the antioxidants were investigated both in chemical models containing the precursors (tripalmitoyl glycerol, 1,2-dipalmitoyl-sn-glycerol, monopalmitoyl glycerol, and sodium

Jesús Sot et al.
Biophysical journal, 107(12), 2828-2837 (2014-12-18)
The origin of resistance to detergent solubilization in certain membranes, or membrane components, is not clearly understood. We have studied the solubilization by Triton X-100 of binary mixtures composed of egg sphingomyelin (SM) and either ceramide, diacylglycerol, or cholesterol. Solubilization
Sören Backhaus et al.
Journal of lipid research, 58(6), 1055-1066 (2017-04-14)
Interleukin (IL)-1β is a potent pro-inflammatory cytokine of innate immunity involved in host defense. High systemic IL-1β levels, however, cause life-threatening inflammatory diseases, including systemic inflammatory response syndrome. In response to various danger signals, the pro-form of IL-1β is synthesized
Xi Zhu et al.
Theranostics, 7(7), 1990-2002 (2017-06-24)
The present work proposes a unique de-PEGylation strategy for controllable delivery of small interfering RNA (siRNA) using a robust lipid-polymer hybrid nanoparticle (NP) platform. The self-assembled hybrid NPs are composed of a lipid-poly(ethylene glycol) (lipid-PEG) shell and a polymer/cationic lipid

Obesity, characterized by expansion and metabolic dysregulation of white adipose tissue (WAT), has reached pandemic proportions and acts as a primer for a wide range of metabolic disorders. Remodeling of WAT lipidome in obesity and associated comorbidities can explain disease
