Human “free-N-terminome” analysis

ABSTRACT: The high throughput characterization of protein N-termini is becoming an emerging challenge in the proteomics and proteogenomics fields. The present study describes the N-terminal oriented analysis of human mitochondria enriched samples by the trimethoxyphenyl phosphonium (TMPP) labeling approach (N-TOP and dN-TOP approaches (Gallien et al, 2009, Bertaccini et al. 2013)). The dN-TOP strategy based on a double light/heavy TMPP labeling has been optimized in order to improve and automate the workflow for efficient, fast and reliable high throughput N-terminome analysis.

The high throughput characterization of protein N-termini is becoming an emerging challenge in the proteomics and proteogenomics fields. The present study describes the free N-terminome analysis of human mitochondria-enriched samples using trimethoxyphenyl phosphonium (TMPP) labelling approaches. Owing to the extent of protein import and cleavage for mitochondrial proteins, determining the new N-termini generated after translocation/processing events for mitochondrial proteins is crucial to unde ...[more]

Comparison of Labeling Methods for gene expression analysis on the NimbleGen platform

Project description:Comparison of ds-cDNA, Indirect and Direct Random Labeling Methods for gene expression analysis on the NimbleGen platform. Expression profiles from artemisinic acid-producing S. cerevisiae strain EPY330 and non-producing strain EPY338 are compared for each labeling method tested. The labeling methods and their comparison are described in detail in Ouellet et al., BMC Biotech 2009. Strains were described in detail previously in Ro et al.

plant rabt n°1-Plant RABT n°1

Project description:adt12-01_uprt - plant rabt n°1 - Impact of RNA labeling by Plant RABT on plant transcriptome - Determine the incidence of RNA marking by the RABT method Plantation on the plants transcriptome. In several studies Clearly et al. have described a method referred as "4TU tagging" which can be use to study mRNA synthesis and decay either in a mixed population of cells or in a specific cell type (Cleary, Meiering et al. 2005, Zeiner, Cleary et al. 2008, Miller, Robinson et al. 2009, Rabani et al., 2011). Through the specific cell type expression in drosophila and mammalian cells of theToxoplasma gondii uracil PhosphoribosylTransferase activity and the metabolization of the uracil analog 4-thiouracil (4 TU), mRNA were selectively tagged, purified and used in microarray based analysis.

Argonaute HITS-CLIP in wild-type and APOBEC1-deficient BMDMs

Project description:To investigate the possible consequences of APOBEC1 editing for miRNA targeting, high-throughput sequencing of RNA isolated by cross-linking immunoprecipitation (HITS-CLIP) of the Argonaute (Ago) proteins (Chi et al., 2009) was performed in BMDMs derived from wild-type and Apobec1-/- littermates.

Dynamic transcriptome analysis of osmotic stress response

Project description:Dynamic transcriptome analysis of osmotic stress response. Unperturbed RNA synthesis and decay rates can be obtained via metabolic RNA labeling and kinetic modeling (Cleary et al, 2005; Kenzelmann et al, 2007; Dolken et al, 2008; Friedel and Dolken, 2009; Miller et al, 2009). The nucleoside analog 4-thiouridine (4sU) is taken up by eukaryotic cells and incorporated into mRNA during Pol II transcription (Melvin et al, 1978). The thiol-labeled newly transcribed RNA can then be isolated by affinity chromatography (Kenzelmann et al, 2007) or by biotinylation and purification with streptavidin-coated magnetic beads (Cleary et al, 2005; Dolken et al, 2008).

Large-scale gene expression profiling of hepatocellular adenomas

Project description:Hepatocellular adenomas (HCA) are rare benign tumors mainly developed in women after 2 years of oral contraceptive use (Rooks et al., 1979). HCA are also related to other risk factors (obesity, vascular diseases, androgen and alcohol intake) or to different genetic diseases (Mac Cune Albright syndrome, glycogen storage diseases type 1a and MODY3 diabetes caused by HNF1A germline mutation) (Calderaro et al., 2013; Nault et al., 2013a). Bleeding and malignant transformation to hepatocellular carcinoma (HCC) can occur as severe complications observed respectively in 30-50% and 5% of the cases. In the past 10 years, we identified 4 major molecular subgroups of HCA defined by (1) mutations inactivating HNF1A (H-HCA, 35% of the HCA) (Bacq et al., 2003; Bluteau et al., 2002; Jeannot et al., 2010), (2) activation of ß-catenin by mutations in exon 3 (bHCA, 15%) (Chen et al., 2002), (3) inflammatory phenotype with STAT3 activation (IHCA, 50%) (Bioulac-Sage et al., 2009; Zucman-Rossi et al., 2006), (4) a tumor subgroup of HCA with Sonic Hedgehog pathway activation due to recurrent focal deletions (shHCA) (Nault et al. ,in preparation) and (5) the remaining unclassified tumors (UHCA, 10%) (Bioulac-Sage et al., 2009). Among bHCA, half displayed both inflammatory and ß-catenin activated phenotypes (bIHCA). Inflammatory adenomas (IHCA) are caused by IL6ST somatic mutation activating gp130 in 60% of the cases (Rebouissou et al., 2009) whereas other IHCA are mutated for STAT3 itself (Pilati et al., 2011) or GNAS (Nault et al., 2012) but in the remaining 30% cases no mutation (NM) were identified yet. This molecular classification is currently accepted in clinical practice using either immunohistochemical markers (Bioulac-Sage et al., 2009; Bioulac-Sage et al., 2007) or in radiology at MRI (Laumonier et al., 2008) and it has dramatically improved the diagnosis and prognostic assessment of HCA.

Streptococcus agalactiae Panproteome

Project description:Streptococcus agalactiae (Lancefield’s group B Streptococcus, GBS) is a major bacterial species of genus Streptococcus and has medical and veterinary importance by affecting mainly humans (Maione et al., 2005; Johri et al., 2006), cattle (Keefe, 1997) and fish (Mian et al., 2009). The GBS is the most important pathogen for the Nile tilapia, a global commodity of the aquaculture sector, causing outbreaks of septicemia and meningoencephalitis (Hernández et al., 2009; Mian et al., 2009). This study aimed to evaluate the global abundancy of proteins among the main genotypes of GBS isolated from fish identified in Brazil using a label free shotgun liquid chromatography-ultra definition mass spectrometry (LC-UDMSE) approach and to compare the differential expression of proteins identified between isolates from fish and human.
