The grease trap: uncovering the mechanism of the hydrophobic lid in Cutibacterium acnes lipase[S]

Journal of Lipid Research, 2020
Acne is one of the most common dermatological conditions, but the details of its pathology are unclear, and current management regimens often have adverse effects. Cutibacterium acnes is known as a major acne-associated bacterium that derives energy from

Physical and chemical processes and the morphofunctional characteristics of human erythrocytes in hyperglycaemia [PDF]

, 2017
Background: This study examines the effect of graduated hyperglycaemia on the state and oxygen-binding ability of hemoglobin, the correlation of phospholipid fractions and their metabolites in the membrane, the activity of proteolytic enzymes and the ...

Coenzyme A mitigates cystine‐deprivation‐induced ferroptosis by suppressing the iron‐starvation response

The FEBS Journal, EarlyView.
Cystine (Cys2) deprivation in pancreatic cancer cells induces oxidative stress that destabilizes cytosolic iron–sulfur cluster (ISC) proteins, triggering an iron‐regulatory protein (IRP)‐mediated iron‐starvation response (ISR). This leads to increased iron uptake (via TFRC), an expanded labile iron pool, and ferroptosis.

Specific uptake of DHA by the brain from a structured phospholipid, AceDoPC®

Oilseeds and fats, crops and lipids, 2017
Docosahexaenoic acid (DHA; 22:6 ω-3) is highly enriched in the brain and is required for proper brain development and function. Its deficiency has been shown to be linked with the emergence of neurological diseases.

Regulation of autotaxin expression and secretion by lysophosphatidate and sphingosine 1-phosphate

Journal of Lipid Research, 2015
Autotaxin (ATX) is a secreted enzyme, which produces extracellular lysophosphatidate (LPA) from lysophosphatidylcholine (LPC). LPA activates six G protein-coupled receptors and this is essential for vasculogenesis during embryonic development.

Fatty acid 16:4(n-3) stimulates a GPR120-induced signaling cascade in splenic macrophages to promote chemotherapy resistance [PDF]

, 2017
Although chemotherapy is designed to eradicate tumor cells, it also has significant effects on normal tissues. The platinum-induced fatty acid 16:4(n-3) (hexadeca-4,7,10,13-tetraenoic acid) induces systemic resistance to a broad range of DNA-damaging ...

Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

The FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

From Classical to Alternative Pathways of 2-Arachidonoylglycerol Synthesis: AlterAGs at the Crossroad of Endocannabinoid and Lysophospholipid Signaling

Molecules
2-arachidonoylglycerol (2-AG) is the most abundant endocannabinoid (EC), acting as a full agonist at both CB1 and CB2 cannabinoid receptors. It is synthesized on demand in postsynaptic membranes through the sequential action of phosphoinositide-specific ...

Hypochlorous acid-mediated generation of glycerophosphocholine from unsaturated plasmalogen glycerophosphocholine lipids

Journal of Lipid Research, 2007
The myeloperoxidase-derived metabolite hypochlorous acid (HOCl) promotes the selective cleavage of plasmalogens into chloro fatty aldehydes and 1-lysophosphatidylcholine (LPC).
