Preparation of thioester substrates and development of continuous spectrophotometric assays for phospholipase A1 and monoacylglycerol lipase

Journal of Lipid Research, 1981
Current assays of phospholipase A1 (EC 3.1.1.32) and monoacylglycerol lipase (EC 3.1.1.23) activities in tissues are discontinuous, laborious, and expensive. Some spectrophotometric substrates were synthesized to alleviate this problem. Thioester analogs

Covalent fluorescent probes for 2‐arachidonoylglycerol metabolic pathways

British Journal of Pharmacology, EarlyView.
Abstract Covalent fluorescent probes have emerged as versatile chemical tools to visualise active enzymes in complex biological systems. When tailored for specific applications, ranging from activity‐based protein profiling for drug development to high spatiotemporal resolution imaging of enzymatic activities, these probes provide unique insights into ...

Impact of incretin analogues on lipid and lipoprotein metabolism in obesity and diabetes

British Journal of Pharmacology, EarlyView.
Abstract Incretin‐based therapies have gained momentum as a key strategy for reducing cardiovascular risk in individuals with obesity and/or type 2 diabetes (T2D). It remains unclear whether the cardiovascular benefits reflect a direct reduction in atherogenic lipoproteins—namely, low‐density lipoproteins (LDL), very low‐density lipoproteins (VLDL) and

Apparent convergence (at 2-monoacylglycerol level) of phosphatidic acid and 2-monoacylglycerol pathways of synthesis of chylomicron triacylglycerols.

Journal of Lipid Research, 1991
Dietary fats are converted into chylomicron triacylglycerols via the 2-monoacylglycerol and phosphatidic acid pathways of acylglycerol formation. In view of the known positional and fatty acid specificity of the acyltransferases, the triacylglycerol ...

Absorption and Effects of Patch Test Preparations of Hydroperoxides of Limonene and Hydroperoxides of Linalool in Human Ex Vivo Skin

Contact Dermatitis, EarlyView.
This study mimics clinical patch testing for the diagnosis of allergic contact dermatitis, by application of patch test preparations of fragrance terpenes to ex vivo human skin samples. The study investigates the penetration of linalool hydroperoxide and limonene hydroperoxide in skin, alongside an analysis of the lipid‐modifying effects of the patch ...

Tapetal Expression of BnaC.MAGL8.a Causes Male Sterility in Arabidopsis

Frontiers in Plant Science, 2019
Monoacylglycerol lipase (MAGL) hydrolyzes monoacylglycerol, producing free fatty acid and glycerol. Although this enzyme has been shown to play important roles in mammal, its potential function in plants remains poorly understood. In a survey of the MAGL

SCD2 Alleviates Diabetes‐Associated Cognitive Dysfunction by Improving Microglial Lipid Metabolism

Cell Proliferation, EarlyView.
This study reveals a novel mechanism of microglial metabolic dysfunction in diabetic cognitive impairment. Defective SCD2 disrupts monounsaturated fatty acid (MUFA) metabolism, triggering mitochondrial oxidative phosphorylation dysfunction and leading to abnormal lipid droplet accumulation (marked by PLIN2).

Ontogeny of microsomal activities of triacylglycerol synthesis in guinea pig liver.

Journal of Lipid Research, 1987
Because the onset of triacylglycerol-rich lipoprotein synthesis occurs in guinea pig liver during fetal life, we investigated the microsomal enzyme activities of triacylglycerol synthesis in fetal and postnatal guinea pig liver.

The malate–aspartate shuttle supports thermogenic lipid mobilization in brown adipocytes

The FEBS Journal, EarlyView.
Brown fat cells burn lipids within their mitochondria to generate heat. This process involves two energy “shuttles,” one of which is naturally blocked during heat production. We found that the second shuttle (MASh) is not required to generate heat. However, when MASh is disabled, the fatty acids meant for fuel are instead converted back into stored fat.

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.
