MetabolomicsIntracellular metabolites from an experimental manipulation of marine microorganisms
The marine environment holds one of the largest pools of reduced organic carbon on Earth. Within this organic carbon are metabolites produced as a result of microbial activity. This project considers the effects of predation and viral lysis on the metabolites found in the surface ocean. Using seawat...

MetabolomicsPhosphorus availability regulates intracellular nucleotides in marine eukaryotic phytoplankton
Phosphorus limitation is pervasive in the oligotrophic surface ocean and marine microorganisms use different strategies to survive, and thrive, at these low nutrient levels. Eukaryotic algae such as diatoms are extremely sensitive to phosphorus limitation and recent transcriptomics work has suggeste...

MetabolomicsSalmonella Typhimurium reprograms macrophage metabolism via T3SS effector SopE2 to promote intracellular replication and virulence

Salmonella Typhimurium establishes systemic infection by replicating in host macrophages. Here we show that macrophages infected with S. Typhimurium exhibit upregulated glycolysis and decreased serine synthesis, leading to accumulation of glycolytic intermediates. The effects on...

ProteomicsThe intracellular free concentration of EDCs enables successful translation between cell-free and cell-based estrogenic activity assays
Many environmental toxicants can activate the estrogen receptor α (ERα), contributing to disruption of normal endocrine function. Although these activities are known from in silico, in vitro and in vivo models, transferring the active concentrations between the different models is often challenging....

MetabolomicsComparative metabolomic analysis of exudates of microcystin-producing and microcystin-free Microcystis aeruginosa strains

Cyanobacterial harmful algal blooms (cHABs) dominated by Microcystis aeruginosa threaten the ecological integrity and beneficial uses of lakes globally. In addition to producing hepatotoxic microcystins (MC), M. aeruginosa exudates (MaE) contain various compounds with demonstrat...

TranscriptomicsKIM5 intracellular expression profiling
Microarrays were used to determine the transcriptional profile of Y. pestis that is growing inside macrophages. J774A.1 macrophage-like cells were infected with Y. pestis KIM5 and incubated in the presence of gentamicin in tissue culture media. RNA was isolated from intracellular bacteria at vari...

TranscriptomicsPlasticity of transcriptional regulation under antibiotic stress
Evolution of antibiotic resistance in microbes is frequently achieved by acquisition of spontaneous mutations during antimicrobial therapy. Here we demonstrate that inactivation of a central regulator of iron homeostasis (fur) facilitates laboratory evolution of ciprofloxacin resistance in Escherich...

TranscriptomicsTranscription profiling of S. typhimurium during the intracellular growth phase of infection pathogenesis following infection of macrophages
DNA microarrays were used to provide a global transcriptional profile of S. typhimurium during the intracellular growth phase of infection pathogenesis following infection of macrophages.

TranscriptomicsYeast expression data from conditions that inhibit sirtuins
Sir2 is an NAD+-dependent histone deacetylase, and is the founding member of a large, phylogentically conserved, family of such deacetylases called the Sirtuins. The budding yeast, Saccharomyces cerevisiae, harbors 4 paralogs of Sir2, known as Hst1, Hst2, Hst3, and Hst4. Reducing the intracellular N...

TranscriptomicsLeishmania major modulates autophagy in host macrophages during intracellular differentiation
Autophagy generally participates in innate immunity by elimination of intracellular pathogens. However, many of them developed successful strategies to counteract their autolysosomal digestion and lastly to exploit this catabolic cellular process. Protozoan parasites of the genus Leishmania are the ...
