MetabolomicsComprehensive evaluation of untargeted metabolomics data processing software in feature detection, quantification and discriminating marker selection
Data analysis represents a key challenge for untargeted metabolomics studies and it commonly requires extensive processing of more than thousands of metabolite peaks included in raw high-resolution MS data. Although a number of software packages have been developed to facilitate untargeted data proc...

MetabolomicsSelection strengthens the relationship between plant diversity and the metabolic profiles of Plantago lanceolata

• Plant species diversity enhances community productivity, but how plant diversity impacts the metabolome of individual plants and the underlying eco-evolutionary processes remains unclear. This study investigated how plant species diversity and selection for growing in different diversity enviro...

MetabolomicsComprehensive evaluation of untargeted metabolomics data processing software in feature detection, quantification and discriminating marker selection (AB SCIEX TripleTOF 6600 assay)

Data analysis represents a key challenge for untargeted metabolomics studies and it commonly requires extensive processing of more than thousands of metabolite peaks included in raw high-resolution MS data. Although a number of software packages have been developed to facilitate untargeted data p...

MetabolomicsMolecular characterization of firefly nuptial gifts: a multi-omics approach sheds light on postcopulatory sexual selection
Postcopulatory sexual selection is recognized as a key driver of reproductive trait evolution, including the machinery required to produce endogenous nuptial gifts. Despite the importance of such gifts, the molecular composition of the non-gametic components of male ejaculates and their interactions...

MetabolomicsA Divergent Selection on Breast Meat Ultimate pH, a Key Factor for Chicken Meat Quality, is Associated With Different Circulating Lipid Profiles

BACKGROUND: Chicken meat has become a major source of protein for human consumption. However, the quality of the meat is not yet under control, especially since pH values that are too low or too high are often observed. In an attempt to get a better understanding of the genetic a...

MetabolomicsMetabolome profiling by untargeted metabolomics and biomarker panel selection using machine-learning for patients in different stages of peripheral neuropathy induced by oxaliplatin

Background: Oxaliplatin-induced peripheral neuropathy (OIPN) poses a significant challenge for patients with colorectal tumor, often resulting in treatment interruption or discontinuation and subsequent treatment failure. Herein, a longitudinal untargeted metabolomic study to reveal the metabolom...

TranscriptomicsThe transcriptional consequences of mutation and natural selection in Caenorhabditis elegans
This set of arrays contains all microarray experiments done involving comparisons among C. elegans natural isolates and mutation-accumulation lines. Abstract: The evolutionary importance of gene-expression divergence is unclear: some studies suggest that it is an important mechanism for evolution by...

TranscriptomicsIntrathymic T-cell selection
Comparisons between untreated primary cells T-cell precursors from the thymus. CD69- thymocytes are from Zap70-deficent mice and are >95% CD4+CD8+. These cells fail to generate intrathymic TCR signals as a result of their lacking Zap70 molecules, and are thus representative of "preselection" CD4+CD8...

TranscriptomicsAnalysis of severe feather pecking behavior in a high feather pecking selection line
Even though feather pecking (FP) in laying hens has been extensively studied, a good solution to prevent chickens from this behavior under commercial circumstances has not been found. Selection against FP behavior is possible, but for a more effective selection across different populations, it is ne...

TranscriptomicsNatural selection on cis and trans regulation in yeasts
Gene expression is regulated both by cis elements, which are DNA segments closely linked to the genes they regulate, and by trans activating factors, which are usually proteins capable of diffusing to unlinked genes. Understanding the patterns and sources of regulatory variation is crucial for under...
