Metabolic Heavy Isotope Labeling to Study Glycerophospholipid Homeostasis of Cultured Cells

Bio-Protocol, 2017
Glycerophospholipids consist of a glycerophosphate backbone to which are esterified two acyl chains and a polar head group. The head group (e.g., choline, ethanolamine, serine or inositol) defines the glycerophospholipid class, while the acyl chains ...

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models

Advanced Functional Materials, EarlyView.
This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...

The Metabolic and Lipidomic Fingerprint of Torin1 Exposure in Mouse Embryonic Fibroblasts Using Untargeted Metabolomics

Metabolites
Torin1, a selective kinase inhibitor targeting the mammalian target of rapamycin (mTOR), remains widely used in autophagy research due to its potent autophagy-inducing abilities, regardless of its unspecific properties.

Behaviour of NBD-head group labelled phosphatidylethanolamines in POPC bilayers: a molecular dynamics study [PDF]

, 2015
A complete homologous series of fluorescent phosphatidylethanolamines (diCnPE), labelled at the head group with a 7-nitrobenz-2-oxa-1,3-diazo-4-yl(NBD) fluorophore and inserted in 1-palmitoyl, 2-oleoyl-snglycero- 3-phosphocholine (POPC) bilayers, was ...

Phosphatidylethanolamine Metabolism in Health and Disease [PDF]

, 2016
Phosphatidylethanolamine (PE) is the second most abundant glycerophospholipid in eukaryotic cells. The existence of four only partially redundant biochemical pathways that produce PE, highlights the importance of this essential phospholipid. The CDP-ethanolamine and phosphatidylserine decarboxylase pathways occur in different subcellular compartments ...

Single‐Cell Computational Frameworks for Quantifying BET Bromodomain Inhibitor Resistance and Screening Re‐Sensitizer Drugs in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
To combat BET inhibitor resistance in triple‐negative breast cancer, we developed two single‐cell computational frameworks. FR20 quantifies resistance by integrating ferroptosis‐related gene signatures, while D‐FR20 screens for potential re‐sensitizers.

The Anti-Inflammatory Effect of Algae-Derived Lipid Extracts on Lipopolysaccharide (LPS)-Stimulated Human THP-1 Macrophages [PDF]

, 2015
Algae contain a number of anti-inflammatory bioactive compounds such as omega-3 polyunsaturated fatty acids (n-3 PUFA) and chlorophyll a, hence as dietary ingredients, their extracts may be effective in chronic inflammation-linked metabolic diseases such

Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response

Advanced Science, EarlyView.
This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine

Circulating Rhythmic Metabolites and Causal Risk of Type 2 Diabetes in Adults in the Canadian Longitudinal Study on Aging. [PDF]

Diabetes Obes Metab
ABSTRACT Aims Circadian regulation of metabolism is an important factor in metabolic health, yet the role of rhythmic metabolites in Type 2 diabetes development remains poorly understood. This study investigated associations between circulating rhythmic metabolites and incident Type 2 diabetes risk and evaluated causal relationships using two‐sample ...

Reactive gamma-ketoaldehydes as novel activators of hepatic stellate cells in vitro [PDF]

, 2016
Aims: Products of lipid oxidation, such as 4-hydroxynonenal (4-HNE), are key activators of hepatic stellate cells (HSC) to a pro-fibrogenic phenotype. Isolevuglandins (IsoLG) are a family of acyclic γ-ketoaldehydes formed through oxidation of arachidonic
