MetabolomicsGrowth control of the eukaryote cell: a systems biology study in yeast
Metabolic control analysis is being exploited in a systems biology study of the eukaryotic cell. Using chemostat culture, we have measured the impact of changes in flux (growth rate) on the transcriptome, proteome, endometabolome and exometabolome of the yeast Saccharomyces cerevisiae. Each function...

MetabolomicsThe response of Chlamydomonas reinhardtii to nitrogen deprivation: a systems biology analysis

Drastic alteration in macronutrients causes large changes in gene expression in the photosynthetic unicellular alga Chlamydomonas reinhardtii. Preliminary data suggested that cells follow a biphasic response to this change hinging on the initiation of lipid accumulation, and we hypothesized that ...

MetabolomicsLinking soil biology and chemistry in biological soil crust using isolate exometabolomics
Metagenomic sequencing provides a window into microbial community structure and metabolic potential; however, linking these data to exogenous metabolites that microorganisms process and produce (the exometabolome) remains challenging. Previously, we observed strong exometabolite niche partitioning a...

MetabolomicsImmune Stimulation via Wounding Alters Chemical Profiles of Adult Tribolium castaneum
Group-living individuals experience immense risk of disease transmission and parasite infection. In social and in some non-social insects, disease control with immunomodulation arises not only via individual immune defenses, but also via infochemicals such as contact cues and (defensive) volatiles t...

MetabolomicsChemical Diversity and Classification of Secondary Metabolites in Nine Bryophyte Species

The central aim in ecometabolomics and chemical ecology is to pinpoint chemical features that explain molecular functioning. The greatest challenge is the identification of compounds due to the lack of constitutive reference spectra, the large number of completely unknown compounds, and bioinform...

MetabolomicsComprehensive systems biology analysis of a seven-month cigarette smoke inhalation study in C57BL/6 mice
Smoking of combustible cigarettes has a major impact on human health. Using a systems toxicology approach in a model of chronic obstructive pulmonary disease (C57BL/6 mice), we assessed the health consequences in mice of smoke derived from a prototype modified risk tobacco product (pMRTP) as compare...

MetabolomicsPhenomic and multiomic characterisation of microsatellite-stable colorectal cancer reveals novel biology and targets of vulnerability

Integrating data from approximately 2,000 tumour samples, corresponding to ~4,500 platform-specific multiomic sample profiles, and 195,246 single cells/nuclei from diverse in-house and publicly available datasets, single-to-integrated multiomic and clinical phenome data fusion analysis uncovers t...

MetabolomicsThe timing of bacterial mesophyll infection shapes the leaf chemical landscape during the interaction

Chemistry in eukaryotic intercellular spaces is shaped by both hosts and symbiotic microorganisms such as bacteria. Pathogenic microorganisms like barley associated Xanthomonas translucens (Xt) swiftly overtake the inner leaf tissue becoming the dominant microbial community member during disease ...

MetabolomicsPlant species richness promotes the decoupling of leaf and root defence traits while species-specific responses in physical and chemical defences are rare

The increased positive impact of plant diversity on ecosystem functioning over time is often attributed to the gradual accumulation of mutualists and dilution of antagonists in diverse plant communities. While increased plant diversity alters traits related to resource acquisition, it remains unc...

MetabolomicsOptimizing peak picking and development of a suspect screening tool for rapid annotation of the human chemical exposome from LC- HRMS datasets
The technological advances of cutting-edge high-resolution mass spectrometry (HRMS) has set the stage for a new paradigm for exposure assessment. However, it is critical to ensure that bioinformatics software developed to process raw HRMS data can disentangle low-abundant xenobiotics from the noise....
