Label-free proteomics of immuno-purified SYP61-trans-Golgi Network compartment in control condition and upon sphingolipid acyl-chain length reduction by metazachlor.

ABSTRACT: The trans-Golgi Network (TGN) in plants is a main sorting hub for proteins and lipids. The lipid composition at the TGN is instrumental to the polar sorting of the auxin efflux carrier PIN2 from TGN to the apical membrane. Here, we immuno-purified the full and intact TGN using the TGN-resident syntaxin SYP61 to identify and quantify TGN-proteins which abundance at TGN is dependent on the acyl-chain length of very-long chain fatty acids-containing lipids such as sphingolipids.

Proteomic study of low-birth-weight nephropathy molecular pathogenesis in rats

Project description:We investigated the molecular pathogenesis of LBW rats obtained by intraperitoneal injection of dexamethasone into pregnant animals. Normal-birth-weight (NBW) rats were used as controls with seven animals per group. When the rats were four weeks old, the left kidneys were removed and used for comprehensive label-free proteomic studies

A proteomic analysis of the surface attachment in Pseudomonas aeruginosa early as 20 minutes incubation.

Project description:The goal of the project is the study of molecular events occurring during the attachment phase, first step of the biofilms formation. Thanks to an original growth system developed in our laboratory, we were able to compare, for the first time, the protein content of P. aeruginosa immobilized for 20 minutes only to that of their planktonic counterparts.

Critical role of Aquaporin-1 and telocytes in infantile hemangioma response to propranolol beta-blockade

Project description:Propranolol, a non-selective β-adrenergic receptor (ADRB) antagonist, is the first-line therapy for severe infantile hemangiomas (IH). Since the incidental discovery of propranolol efficacy in IH, preclinical and clinical investigations have shown evidence of adjuvant propranolol response in some malignant tumors. However, the mechanism for propranolol antitumor effect is still largely unknown, owing to the absence of a tumor model responsive to propranolol at non-toxic concentrations. Immunodeficient mice engrafted with different human tumor cell lines were treated with anti-VEGF bevacizumab, to create a model sensitive to propranolol. Proteomics analysis was used to reveal propranolol-mediated protein alteration correlating with tumor growth inhibition and Aquaporin-1 (AQP1), a water channel modulated in tumor cell migration and invasion, was identified. IH tissues and cells were then functionally investigated. Our functional protein association networks analysis and knockdown of ADRB2 and AQP1 indicated that propranolol treatment and AQP1 downregulation trigger the same pathway, suggesting that AQP1 is a major driver of betablockers antitumor response. Examining AQP1 in human hemangioma samples, we found it exclusively in a perivascular layer, so far unrecognized in IH, made of telocytes (TC). Functional in vitro studies showed that AQP1-positive telocytes play a critical role in IH response to propranolol and that modulation of AQP1 in IH-TC by propranolol or shAQP1 decreases capillary-like tube formation in a Matrigel based angiogenesis assay. We conclude that IH sensitivity to propranolol may rely at least in part to a cross talk between lesional vascular cells and stromal telocytes.

Proteome of mouse striatal dopamine synaptosomes purified by fluorescence sorting

Project description:Dopamine transmission is a monoaminergic system involved in reward processing and motor control. Volume transmission is thought to be the main mechanism by which monoamines modulate effector transmission though synaptic structures are scarcely described. In the present work we aimed to unravel the cellular and molecular synaptome of single projection pathways (Zhu F, Cizeron M, Qiu Z, Benavides-Piccione R, Kopanitsa MV, Skene NG, Koniaris B, DeFelipe J, Fransén E, Komiyama NH & Grant SGN (2018) Architecture of the Mouse Brain Synaptome. Neuron 99: 781–799.e10). To that end, we established a workflow combining fluorescence tracing of the dopaminergic pathway, fluorescence activated synaptosome sorting and mass spectrometry-based proteomics. With this approach we provide the first ex-vivo model to thoroughly analyse the cellular and molecular organisation of dopaminergic synapses from mouse striatum.

How a tRNA modifying enzyme facilitates RNase P activity in Arabidopsis nuclei

Project description:RNase P is essential to perform the 5’ maturation of tRNA precursors. Beyond the ancestral form of RNase P containing a ribozyme, protein-only RNase P enzymes termed PRORP were identified in eukaryotes. In human mitochondria, PRORP forms a complex with two protein partners to become functional. In plants, although PRORP enzymes are active alone, we investigate their interaction network to understand their integration with gene expression pathways. Here we investigate functional interactions involving the Arabidopsis nuclear RNase P PRORP2. We show, using an immuno-affinity strategy, that PRORP2 makes a complex with the tRNA methyl transferases TRM1A and B in vivo. Beyond RNase P, these enzymes can also interact with RNase Z. We show that TRM1A/B localize in the nucleus and find that their double knock out mutation results in a severe macroscopic phenotype. Using a combination of immuno-detections, mass spectrometry and a transcriptome wide tRNAseq approach, we observe that TRM1A/B are responsible for the m2,2G26 modification of 70% of cytosolic tRNAs in vivo. We use the transcriptome wide tRNAseq approach as well as RNA blot hybridizations to show that RNase P activity is impaired in TRM1A/B mutants for specific tRNAs, in particular, tRNAs containing a m2,2G modification at position 26 that are strongly down-regulated in TRM1A/B mutants. Altogether, results indicate that the m2,2G adding enzymes TRM1A/B functionally cooperate with nuclear RNase P in vivo for the early steps of cytosolic tRNAs biogenesis.

Arabidopsis endomembrane enrichments: Affinity enrichment of RABF2b/RFP-ARA7

Project description:Our aim was to dissect subcellular trafficking routes by enriching for partially overlapping subpopulations of endosomal proteomes associated with endomembrane markers. We selected RABD2a/ARA5, RABF2b/ARA7, RABF1/ARA6, and RABG3f as markers for combinations of the Golgi, trans-Golgi Network (TGN), Early Endosomes (EE), secretory vesicles, Late Endosomes (LE), Multivesicular Bodies (MVB) compartments and tonoplast. As comparisons we used Golgi transport 1 (GOT1), which localises to the Golgi, Clathrin Light Chain 2 (CLC2) labelling Clathrin-coated vesicles and pits and the Vesicle Associated Membrane Protein 711 (VAMP711) present at the tonoplast. We developed an easy-to-use method by refining published protocols based on affinity purification of fluorescent fusion constructs to these seven subcellular marker proteins in Arabidopsis thaliana seedlings.
