MetaboLights MTBLS1334 - GNPS LipidCreator workbench to probe the lipidomic landscape - Collision Energy Optimization and Fragment Intensity Prediction for Lipid Mediators, Agilent QTof
Ontology highlight
ABSTRACT: Here we present LipidCreator, a software that fully supports targeted lipidomics assay development. LipidCreator offers a comprehensive framework to compute MS/MS fragment masses for over 60 lipid classes. LipidCreator provides all functionalities needed to define fragments, manage stable isotope labeling, optimize collision energy and generate in silico spectral libraries. We validate LipidCreator assays computationally and analytically and prove that it is capable to generate large targeted experiments to analyze blood and to dissect lipid-signaling pathways such as in human platelets. In MTBLS1334, 55 lipid mediator standards were used to study the lipid fragmentation on the Agilent QTof 6545 MS platform (Agilent Technologies, Waldbronn, Germany), build optimal collision energy models and create an in-silico spectral library for use with LipidCreator. Lipid fragment masses of mediators were validated with the Metlin database (https://metlin.scripps.edu/). Studies linked to this manuscript include; MTBLS1381; LipidCreator: Platelet isolation and stimulation - Targeted Lipid Mediator Profiling MTBLS1382; LipidCreator: Platelet isolation and stimulation - DIA Lipid Mediator Validation

DIA method preparation and data analysis were performed with Skyline. We used LipidCreator as an external tool in Skyline to generate a collision-energy specific transition list for the mediators 12-HETE, 13-HODE, 15-HETE, arachidonic acid (AA),<strong> </strong>docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA) and thromboxane B2 (TXB2) and their deuterated counterparts 12-HETE-d8, 13-HODE-d4, 15-HETE-d8, AA-d8, DHA-d5, EPA-d5 and TXB2-d4, at a normalized collision energy NCE=21. We also used LipidCreator's relative fragment intensity prediction model to generate a custom spectral library for the light and heavy mediators. We transfered both the transition list and the spectral library directly from LipidCreator to Skyline and exported the dot product values after manual fragment peaks review.</p><p><br></p><p>Studies linked to this manuscript include;</p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1333' rel='noopener noreferrer' target='_blank'>MTBLS1333; LipidCreator: Collision Energy Optimization and Fragment Intensity Prediction for Lipid Mediators - Thermo QExactive HF</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1334' rel='noopener noreferrer' target='_blank'>MTBLS1334; LipidCreator: Collision Energy Optimization and Fragment Intensity Prediction for Lipid Mediators - Agilent QTof</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1369' rel='noopener noreferrer' target='_blank'>MTBLS1369; LipidCreator: Platelet isolation and stimulation - Targeted Phospho- and Glycerolipid Profiling</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1375' rel='noopener noreferrer' target='_blank'>MTBLS1375; LipidCreator: Targeted lipidomics analysis of Human Plasma samples and comparison with NIST SRM 1950 standard</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1376' rel='noopener noreferrer' target='_blank'>MTBLS1376; LipidCreator: Targeted lipidomics analysis of S. cerevisiae to determine true and false identification</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1381' rel='noopener noreferrer' target='_blank'>MTBLS1381; LipidCreator: Platelet isolation and stimulation - Targeted Lipid Mediator Profiling</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1382' rel='noopener noreferrer' target='_blank'>MTBLS1382; LipidCreator: Platelet isolation and stimulation - DIA Lipid Mediator Validation</a></p>

It has a limited number of fatty acyls and double bonds, and certain fatty acyls and lipid classes do not occur in it, which is important for our consecutive false identification calculations. Therefore, the yeast matrix from the theoretical calculation, 21 target lipids and 21 decoy lipids from commercially available lipid standards that are known to not be present in the yeast lipidome were selected. Based on our previous results, none of the lipid species was redundant among all three sets.</p><p><br></p><p>Studies linked to this manuscript include;</p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1333' rel='noopener noreferrer' target='_blank'>MTBLS1333; LipidCreator: Collision Energy Optimization and Fragment Intensity Prediction for Lipid Mediators - Thermo QExactive HF</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1334' rel='noopener noreferrer' target='_blank'>MTBLS1334; LipidCreator: Collision Energy Optimization and Fragment Intensity Prediction for Lipid Mediators - Agilent QTof</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1369' rel='noopener noreferrer' target='_blank'>MTBLS1369; LipidCreator: Platelet isolation and stimulation - Targeted Phospho- and Glycerolipid Profiling</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1375' rel='noopener noreferrer' target='_blank'>MTBLS1375; LipidCreator: Targeted lipidomics analysis of Human Plasma samples and comparison with NIST SRM 1950 standard</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1376' rel='noopener noreferrer' target='_blank'>MTBLS1376; LipidCreator: Targeted lipidomics analysis of S. cerevisiae to determine true and false identification</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1381' rel='noopener noreferrer' target='_blank'>MTBLS1381; LipidCreator: Platelet isolation and stimulation - Targeted Lipid Mediator Profiling</a></p><p><a href='https://www.ebi.ac.uk/metabolights/MTBLS1382' rel='noopener noreferrer' target='_blank'>MTBLS1382; LipidCreator: Platelet isolation and stimulation - DIA Lipid Mediator Validation</a></p>
