LC/MS/MS method for analysis of E2 series prostaglandins and isoprostanes

Journal of Lipid Research, 2011
15-series prostaglandins (PGE2s) and isoprostanes (isoPGE2s) are robust biomarkers of oxidative stress, possess potent biological activity, and may be derived through cyclooxygenase or free radical pathways.

Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

Advanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

Enzymatic activities of the human AGPAT isoform 3 and isoform 5: localization of AGPAT5 to mitochondria[S]

Journal of Lipid Research, 2011
The enzyme 1-acylglycerol-3-phosphate-O-acyltransferase (AGPAT) converts lysophosphatidic acid (LPA) to phosphatidic acid (PA). In this study, we show enzymatic properties, tissue distribution, and subcellular localization of human AGPAT3 and AGPAT5.

Opsin Is a Phospholipid Flippase [PDF]

Current Biology, 2011
Polar lipids must flip-flop rapidly across biological membranes to sustain cellular life [1, 2], but flipping is energetically costly [3] and its intrinsic rate is low. To overcome this problem, cells have membrane proteins that function as lipid transporters (flippases) to accelerate flipping to a physiologically relevant rate.

Identification of a novel GPCAT activity and a new pathway for phosphatidylcholine biosynthesis in S. cerevisiae

Journal of Lipid Research, 2008
Turnover of phospholipids in the yeast Saccharomyces cerevisiae generates intracellular glycerophosphocholine (GPC). Here we show that GPC can be reacylated in an acyl-CoA-dependent reaction by yeast microsomal membranes. The lysophosphatidylcholine that

Overcoming Photodynamic Therapy Resistance: GSH‐Responsive AIE Photosensitizer‐Hydroxycamptothecin Nanoliposomes for Extrahepatic Cholangiocarcinoma

Advanced Healthcare Materials, EarlyView.
A GSH‐responsive AIE nanoplatform (TSH NPs) with RGD‐mediated tumor targeting co‐delivers a photosensitizer (TPA) and HCPT for extrahepatic cholangiocarcinoma. The system synergistically enhances PDT and chemotherapy by suppressing HIF‐1α/VEGF‐driven hypoxic adaptation, effectively overcoming PDT resistance.
