Biochem/physiol Actions

GSK264220A is a potent, active site-targeting, covalent inhibitor against endothelial lipase (EL or LIPG; IC50 = 130 nM) and lipoprotein lipase (LPL or LIPD; IC50 = 100 nM). GSK264220A reduces NeuT expression - or CoCl2 treatment-induced intracellular triacylglycerol & lipid droplets (TAG & LD) increase in MCF-7 (16 & 32 nM) and suppresses LPL-depenent melanoma survival (by ~50% at 18.75 μM; WM852, WM1361). When applied in mice in vivo (30 mg/kg ip.), GSK264220A21 enhances lipid nanoparticles-mediated siRNAs delivery & gene-silencing efficacy.

Endothelial lipase (EL) is a 482-amino-acid protein from the triglyceride lipase gene family that uses a Ser-His-Asp triad for catalysis. Its expression in endothelial cells and preference for phospholipids rather than triglycerides are unique. Animal models in which it is

Endothelial lipase (LIPG) is a cell surface associated lipase that displays phospholipase A1 activity towards phosphatidylcholine present in high-density lipoproteins (HDL). LIPG was recently reported to be expressed in breast cancer and to support proliferation, tumourigenicity and metastasis. Here we

While a variety of short interfering RNA (siRNA) delivery compounds have been developed, a deep understanding of the key parameters that determine the quality of siRNA delivery are not known with certainty. Therefore, an understanding of the factors required for

Alterations in lipid metabolism in cancer cells impact cell structure, signaling, and energy metabolism, making lipid metabolism a potential diagnostic marker and therapeutic target. In this study, we combined PET, desorption electrospray ionization-mass spectrometry (DESI-MS), nonimaging MS, and transcriptomic analyses

It is well recognized that many cancers are addicted to a constant supply of fatty acids (FAs) and exhibit brisk de novo FA synthesis. Upregulation of a key lipogenic enzyme, fatty acid synthase (FASN), is a near-universal feature of human
