MetabolomicsATG2A-mediated DAG transfer recruits DGAT2 for lipid droplet growth

Lipid droplet (LD) growth mechanisms and the roles of LD-associated lipid transfer proteins remain poorly understood. Here, we show that the autophagy lipid transfer protein ATG2A has an anabolic role and promotes LD expansion by transferring diacylglycerol (DAG), and potentially triacylglycerol ...

ProteomicsInteractome analysis of human phospholipase D and phosphatidic acid-associated protein network
Using a systematic proteomic approach, we define the protein-protein interaction network for PLD superfamily and phosphatidic acid in human cells and reveal diverse cellular signaling events involved for this key protein family and lipid.

MetabolomicsThe impact of genetic stress by ATGL deficiency on the lipidome of lipid droplets from murine hepatocytes
We showed earlier that nutritional stress like starvation or high fat diet resulted in phenotypic changes in the lipidomes of hepatocyte lipid droplets (LDs), representative for the pathophysiological status of the mouse model. Here we extend our former study by adding genetic stress due to knock-ou...

MetabolomicsComprehensive lipid analysis of green Arabica coffee beans by LC-HRMS/MS
Lipids play an important role in coffee bean development, coffee brew and in the effects of coffee on human health. They account for around 17% of the dry bean weight and encompass different classes and subclasses, mostly triacylglycerols (TAG) and a minor quantity of phospholipids (PL) and βN-alkan...

ModelsGuard Cell Abscisic Acid Signaling
Plants both lose water and take in carbon dioxide through microscopic stomatal pores, each of which is regulated by a surrounding pair of guard cells. During drought, the plant hormone abscisic acid (ABA) inhibits stomatal opening and promotes stomatal closure, thereby promoting water conservation. ...

ProteomicsCFAP418 participates in membrane-associated cellular processes through binding lipids during ciliogenesis
iliopathies and retinal degenerative diseases are heterogeneous groups of genetic diseases. CFAP418 is a causative gene of both diseases, and its sequence is evolutionarily conserved. Here, we employ affinity purification coupled with mass spectrometry and quantitative lipidomic, proteomic, and phos...

MetabolomicsA combined direct infusion/reversed phase chromatography – high resolution mass spectrometry workflow for accurate absolute lipid quantification with 13C- internal standards
We propose a fully automated novel workflow for lipidomics based on flow injection, followed by liquid chromatography-high-resolution mass spectrometry (FI/LC-HRMS). The workflow combined in-depth characterization of the lipidome achieved via reversed-phase LC-HRMS with absolute quantification by us...

ProteomicsPhosphatidic acid features double membrane vesicle formation during Hepatitis C and SARS-CoV-2 infection
Double membrane vesicles (DMVs) are used as replication organelles by pathogenic RNA viruses such as hepatitis C virus (HCV) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Viral DMVs are morphologically analogous to DMVs formed during autophagy, and although the proteins required...

ProteomicsProximity labeling on phosphatidic acid-enriched membranes generated via optogenetic membrane editing
Cellular lipid metabolism is subject to strong homeostatic regulation, but players involved in and mechanisms underlying these pathways remain mostly uncharacterized. Here, we develop and exploit a “Feeding-Fishing” approach coupling membrane editing using optogenetic lipid-modifying enzymes (feedin...
