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...

MetabolomicsMetabolic response to point mutations reveals principles of modulation of in vivo enzyme activity and phenotype
The relationship between sequence variation and phenotype is poorly understood. Here, we use metabolomic analysis to elucidate the molecular mechanism underlying the filamentous phenotype of E. coli strains that carry destabilizing mutations in dihydrofolate reductase (DHFR). We find that partial lo...

MetabolomicsIntracellular iron overload rewires HSC metabolism by impairing mitochondrial fitness
Iron is an essential element for several cellular processes and recent evidence highlighted its role in regulating the function of hematopoietic stem cells (HSCs). When in excess it reduces quiescence and self-renewal, however, whether and how iron influences HSC metabolism is still unknown. Here, w...

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...

MetabolomicsMechanistic insights into the biological activity of S-Sulfocysteine in CHO cells using a multi-omics approach
S-Sulfocysteine (SSC), a bioavailable L-cysteine derivative (Cys), is known to be taken up and metabolized in Chinese hamster ovary (CHO) cells used to produce novel therapeutic biological entities. To gain a deeper mechanistic insight into the SSC biological activity and metabolization, a multi-omi...

MetabolomicsCharacterization of small intracellular vesicles uncovers their potential as drug carriers and therapeutic agents

Small extracellular vesicles (sEVs) have been extensively investigated as a source of clinically relevant cargo. Alongside the secretion of EVs, such as exosomes, cells house a multitude of internal vesicles involved in various physiologic processes and metabolic activities. Herein, we developed ...

MetabolomicsDiscovery of isokurarinone as an ATCase-Engaging Lead with potent activity against methicillin-resistant Staphylococcus aureus

The global proliferation of methicillin-resistant Staphylococcus aureus (MRSA) persists as a significant contributor to challenging infections, highlighting the urgent necessity for therapies that utilize novel mechanisms. Aspartate transcarbamoylase (ATCase), which catalyzes the initial committe...

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...

MetabolomicsL-leucine increases the sensitivity of drug-resistant Salmonella to sarafloxacin by stimulating central carbon metabolism and increasing intracellular reactive oxygen species level (LC-MS positive mode)

The overuse of antibiotics has made public health and safety face a serious crisis. It is urgent to develop new clinical treatment methods to combat drug-resistant bacteria to alleviate the health crisis. The efficiency of antibiotics is closely related to the metabolic state of bacteria. However...
