Plant lipids, waxes, fatty acids, GC, Lipid analysis

The Membrane Biogenesis Laboratory (MBL) has a long history of research in membrane biogenesis and lipid biosynthesis. This lab is internationally known and has been recently chosen to organise the International Plant Lipid Symposium in 2008. The aims of the research concern the identification and the characterisation of the genes involved in the regulation of lipid metabolism. Using Arabidopsis thaliana as the main plant model, the topics currently developed in the unit are: i/ research project I: Genomics of epicuticular wax metabolism. The objective is to characterise the genes involved in the biosynthesis of epicuticular waxes in order to understand the regulatory mechanisms of the expression of genes, which control the composition of the wax layer in response to various stress conditions. ii/ research project II: Membrane biogenesis and homeostasis. This project aims to characterise the mechanisms controlling the membrane lipid composition, the lipid transfer between organelles and membranes, and the lipid composition of lipid rafts in relation to hormonal signalling. iii/ research project III: SNAREs, lipids and endomembrane dynamics. The objective is to study the role of SNAREs in membrane dynamics between the ER and the Golgi apparatus in the secretory pathway leading to the biogenesis of plasmalemma and the formation of lipid rafts through the secretory pathway. The MBL is one unit of the IFR 103 Integrative Biology which involves 6 labs covering the different areas of plant research (pathogenesis, biotechnology, agronomy), and technological platforms (imaging, lipidomic, metabolism, transcriptome). The MBL has in charge the lipidomic platform which consist of 3 GLC,1 GC/-MS 1 densitometer, 1 phosphor imager and 2 TLC spotters. This platform allows lipid and fatty acid analysis and lipid metabolism studies.

phospholipase A2, lipid mediator, cancer, inflammation

Eleven genes coding for secreted phospholipases A2 (sPLA2s, 14-18 kDa) and 2 types of receptors (M and N) have now been identified in mammalian tissues. sPLA2s and their receptors are found in several tissues, and their expression levels are increased in inflammation, associated diseases, different types of cancer, and neurodegenerative diseases. Although the biological functions of sPLA2s and their receptors are still ill-defined, some sPLA2s are mitogenic and/or apoptotic, pro-inflammatory and/or pro-tumoral, but also anti-tumoral, anti-bacterial, anti-viral, and anti-parasitic. At the molecular level, sPLA2s are most likely bifunctional proteins, acting as both enzymes and ligands for a variety of soluble and membrane proteins. sPLA2 enzymatic activity participates in the control of the rate-limiting step in the production of lipid mediators such as prostaglandins and leukotrienes which are involved in a myriad of biological effects. We have previously identified for the first time the M and N type receptors for sPLA2s using snake venom sPLA2s as ligands. More recently, we have cloned 7 of the 11 known mammalian sPLA2s, and we have shown that several of these enzymes are the natural ligands of the M-type receptor, suggesting that mammalian sPLA2s are true ligands for mammalian proteins. The main objective of our research program is to determine the function of sPLA2s, while continuing their molecular characterization. Our specific aims are : 1) To analyze the molecular properties of sPLA2s and to develop key tools to determine sPLA2 function (recombinant production, native structure, crystallization, enzymatic and binding properties, search of specific inhibitors, characterization of receptors, transgenic mice), 2) To analyze the tissue distribution of sPLA2s and their receptors in normal and pathological states in relation with the following item, 3) To study the role of sPLA2s in three major research areas : colorectal cancer, inflammation, and host defense against viruses, bacteria, and parasites.

INSERM UMR 585 / INSA-Lyon is part of IMBL (Institute for Multidisciplinary Biochemistry of Lipids). This UMR works on lipid signaling, in blood, vascular cells and adipocytes, in the context of aging, atherosclerosis, diabetes and obesity. Lipids of interest are membrane phospholipids as reservoirs of polyunsaturated fatty acids which serve as precursors of eicosanoids and docosanoids. The production of those oxygenated metabolites through cyclooxygenase and lipoxygenase pathways is the main focus. The role of oxidative stress/lipid peroxidation in those pathways as well as their control by polyunsaturated fatty acids of nutritional value are of special interest. The sphingomyelin / ceramide / sphingosine / sphingosine-1-phosphate is also taken into consideration.

adipocyte obesity lipid droplet

Synopsis of current research interest in the field of lipid droplet biology: We are working in the field of metabolic diseases associated with obesity in an INSERM unit in Paris (UMR 671). In these diseases, ectopic lipid storage is a key deleterious event at the whole body level, associated with grave metabolic complications. In this regard, we are interested in lipid trafficking in adipose cells specialized in the storage of fat. Caveolins have been found at the surface of lipid droplets, but their functional role in the dynamics of fat storage remains unknown. Since caveolins are highly expressed in adipocytes, and caveolin-KO mice have revealed a striking inability to store fatty acids from extracellular sources into their adipose tissue, we focused our research on the role of caveolins in lipid homeostasis. In a recently published paper (Le Lay et al., Traffic 2006), we have shown that adipocyte lipid droplet composition was dependent on caveolin expression and that exogenous cholesterol was able to induce caveolin targetting to these lipid droplets through a process sharing many features in common with caveolar endocytosis. We are now interesting in elucidating the dynamic relationship between cell surface and lipid droplets through caveolin trafficking, and identifying the adipocyte lipid species that can be stored through a caveolin dependent pathway. In this line, our future projects deal with the functional role of caveolins in lipid targeting to the fat storage compartment, the lipid droplet.

lysophosphatidic acid, autotaxin, lysophospholipase D, adipocyte,

My group is interested in the regulations and the biological consequences of the release of lysophosphatidic acid (LPA) by adipocytes. We are particularly interrested in a lysophospholipase D (autotaxin) which appears to be the main source of LPA release by adipocytes but which could also be involved in synthesis of several other bioactive phospholipids. ATX expressio is adipose tissue is up-regulated in association with insulin-resistance and type 2 diabetes. In paralelle, we are also interrested in understanding the transduction pathways (particularly the receptors) involved in LPA actions on the different cell types surrounding adipocytes in the adipose tissue including preadipocytes, macrophages, endothelial cells.

neutral lipid, ceramide, bile acid, phytosterol

Our Lipid Analysis Platform belongs to the French Nationale Institute for Health and Medical Research (INSERM). It is located in the Federative Research Institute (IFR30) in Toulouse, France and is associated to the Toulouse Genopole. The platform created in 2003 proposes a number of lipid analysis using chromatographic methods, either adapted from the litterature or original. We are equiped with 3 gas chromatographs (GC) with FID detection, one GC coupled to a mass spectrometer and one liquid chromatograph (HPLC) coupled to a light scattering detector (LSD). We propose qualitative and quantitative analysis of lipid molecules following extraction from micro-samples (biological fluids, tissues, cells). We thus have access to the molecular species of the following lipids : - Neutral lipids including cholesterol and related sterols, diacylglycerol, cholesterol ester and triacylglycerol (on the basis of carbon number) - Free or total fatty acids - Sphingomyelines and usual ceramides - Phytosterols - Bilary acids (conjugated or free) - We are in progress to propose in the near future the analysis of major phospholipids classes, galactolipids and cerebrosides by HPLC-LSD. Analysis are proposed on the basis of a price per sample. Collaboration on specific projects is opened. Present ongoing projects include the fields of intestinal lipid absorption, cancer and apoptosis, lipoprotein metabolism, nervous system functionnning, lipid transduction
