GNPS - Streptomyces sp. CBMAI 2042 Extracts

ABSTRACT: Ethyl Acetate fraction of Streptomyces sp. CBMAI 2042 was investigated for identifying cyclodepsipeptides using electrospray ionisation tandem mass spectrometry (ESI-MS/MS). Without prior isolation, the structural determination was achieved on the basis of mass fragmentation pattern and comparison with the previously established data. The ESI-MS of the fraction in the positive ion mode gave clusters of singly and doubly charged molecular ion peaks. The ESI-MS spectrum showed peaks for the presence of the cyclodepsipeptides Valinomycin, Montanastatin and at least 5 structural analogues never reported before.

Intact Transition Epitope Mapping – Serological Inspection by Epitope EXtraction (ITEM – SIX)

Project description:Precision medicine requests accurate serological inspections to precisely stratify patients for targeted treatment. Intact transition epitope mapping analysis proved seroconversion of a model organism's serum when spiked with a monoclonal murine anti-ovalbumin antibody with epitope-resolution. Isolation of the IgG fraction from blood serum applied two consecutive protein precipitation steps followed by ultrafiltration and resulted in an ESI-MS analysis-ready IgG preparation. For epitope mapping by epitope extraction, the ovalbumin antigen was digested with trypsin. After desalting, the peptide mixture was added to the ESI-MS-ready IgG preparation from converted serum and the solution was incubated to form an immune complex between the ovalbumin-derived epitope peptide and the anti-ovalbumin antibody. Then, the entire mixture of proteins and peptides was directly electrosprayed. Sorting of ions in the mass spectrometer's gas phase, dissociation of the immune complex ions by collision induced dissociation, and recording of the epitope peptide ion which had been released from the immune complex revealed the presence of the anti-ovalbumin antibody in converted serum. Mass determination of the complex-released epitope peptide ion with isotope resolution is highly accurate, guaranteeing high specificity of this novel seroconversion analysis approach which is termed Intact Transition Epitope Mapping – Serological Inspections by Epitope EXtraction (ITEM – SIX).

The impact II, a very high resolution quadrupole time-of-flight instrument for deep shotgun proteomics

Project description:Hybrid quadrupole time-of-flight (QTOF) is one of the two major mass spectrometric technologies used in proteomics. Although based on simple fundamental principles, it has over the last decades greatly evolved in terms of achievable resolution, mass accuracy and dynamic range. The Bruker impact platform of QTOF instruments takes advantage of these developments and here we develop and evaluate the impact II for shotgun proteomics applications. Adaption of our heated LC system achieved very narrow peptide elution peaks. The impact II is equipped with a new collision cell with both axial and radial ion ejection, more than doubling ion extraction at high MS/MS frequencies. The new reflectron and detector improve resolving power compared to the previous model up to 80%, i.e. to 40,000 at m/z 1222. We analyzed the ion current from the inlet capillary and found very high transmission (>80%) up to the collision cell. Simulation and measurement indicated 60% transfer into the flight tube. We adapted MaxQuant for QTOF data, improving absolute average mass deviations to better than 1.45 ppm. More than 4,800 proteins can be identified in a single run of HeLa digest in a 90 min gradient. The workflow achieved high technical reproducibility (R2>0.99) and accurate fold change determination in spike-in experiments over three orders of magnitude in complex mixtures. Using label-free quantification we rapidly quantified haploid against diploid yeast and characterized overall proteome differences in mouse cell lines originated from different tissues. Finally, after high pH reversed-phase fractionation we identified 9,515 proteins in a triplicate measurement of HeLa peptide mixture and 11,257 proteins in cerebellum â€“ the highest proteome coverage measured with a QTOF instrument so far.

Annotation of the human adult urinary metabolome and metabolite identification using ultra high performance liquid chromatography coupled to a LTQ-Orbitrap mass spectrometer

Project description:This study deals with the annotation of the human adult urinary metabolome and metabolite identification from electrospray-mass spectrometry (ESI-MS) based metabolomics datasets. Metabolite identification was achieved using two complementary approaches: (i) formal identification by matching chromatographic retention times, mass spectra and also product ion spectra (if required) of metabolites to be characterized in biological datasets to those of reference compounds, and, (ii) putative identification from biological data thanks to MS/MS experiments for metabolites not available in our chemical library. By these means, 384 metabolites corresponding to 1484 annotated features (659 in negative ion mode and 825 in positive ion mode) were characterized in human urine samples. Of these metabolites, 191 and 67 were formally and putatively identified, respectively.

Determination of 5-methyluridine in messenger RNA of mammals

Project description:The discovery of dynamic and reversible modifications in messenger RNA (mRNA) is opening new directions in RNA modification-mediated regulation of biological processes. Methylation is the most prevalent modification occurring in mRNA and the methylation group is mainly decorated in the adenine, cytosine, and guanine base, or in the 2’-hydroxyl group of ribose. However, methylation of the uracil base (5-methyluridine, m5U) hasn’t been discovered in mRNA of eukaryotes. In the current study, we established a method by N-cyclohexyl-N’-β-(4-methylmorpholinium) ethylcarbodiimide p-toluenesulfonate (CMCT) labelling coupled with liquid chromatography-electrospray ionization-mass spectrometry analysis (LC-ESI-MS/MS) for the sensitive determination of uridine modifications in RNA. Our results demonstrated that the detection sensitivities of uridine modifications in RNA increased up to 1543 folds upon CMCT labelling. Using the developed method, we identified the distinct existence of m5U in mRNA of various mammalian cells and tissues. In addition, the stable isotope tracing monitored by mass spectrometry revealed that the methylation group of m5U originated from S-Adenosyl-L-methionine (SAM). Our study expanded the list of modifications occurring in mRNA of mammals. Future work on transcriptome-wide mapping of m5U will further uncover the functional roles of m5U in mRNA of mammals.

Expression analysis of Kasumi-1 cells treated with or without FTY720

Project description:The clinical outcomes of M2 subtype Acute Myeloid Leukemia (AML-M2) with t(8;21) are poor. Here we report that FTY720 (Fingolimod), a sphingosine analogue and an FDA approved drug for treatment of multiple sclerosis, showed great antitumorigenic activity against Kasumi-1 cell line, xenograft mouse model and leukemic blasts isolated from AML-M2 with t(8;21) patients. Primary investigation indicated that FTY720 caused cell apoptosis through caspase and protein phosphatase 2A (PP2A) activation. Transcriptomic profiling further revealed that FTY720 treatment could upregulate AML1 target genes and interfere with genes involved in ceramide synthesis. FTY720 treatment led to the elimination of AML1-ETO oncoprotein and caused cell cycle arrest. More importantly, FTY720 treatment resulted in rapid and significant increment of pro-apoptotic ceramide levels, determined by HPLC-ESI-MS/MS (high-performance liquid chromatography-electrospray ionization tandem mass spectrometry) based lipidomic approaches. Additionally, structural simulation model indicated that the directly binding of ceramide to inhibitor 2 of PP2A (I2PP2A) could reactivate PP2A and cause cell death. This study demonstrates, for the first time, that accumulation of ceramide plays a central role in FTY720 induced cell death of AML-M2 with t(8;21). Targeting sphingolipid metabolism by using FTY720 may provide novel insight into drug development for AML-M2 treatment. A six chip study using total RNA recovered from three separate cultures of DMSO-treated Kasumi-1 cells and three separate cultures of FTY720-treated Kasumi-1 cells.Each chip measures the expression level of genes from DMSO-/FTY720-treated Kasumi-1 cells.
