Dean Jones/ Young-Mi Go Lab
The Jones/Go lab’s research is focused on mechanisms of redox biology and their interactions with metabolism. We have also contributed to numerous areas of research through our use of high-throughput, untargeted metabolomic analyses in our own studies of environmental health and nutrition as well as collaborative research in many other areas of human health.

Major Areas of Research
Redox Biology
We have contributed more than 100 peer-reviewed publications on thiol antioxidant systems dependent upon glutathione (GSH) and thioredoxins. Dr. Jones developed analytical methods for measuring GSH and GSH redox potentials in human plasma, and these methods are now widely used in clinical research to understand the role oxidative stress in human diseases. Our research has since spread to numerous topics within redox biology, including extracellular redox signaling, subcellular compartmentalization of redox states, and characterization of the redox proteome. We have also influenced conceptual thinking in the field, with contributions such as The Redox Code and The Redox Theory of Aging.

Metabolomics
In the past decade, we have developed methodology for high-throughput chemical profiling with high resolution mass spectrometry. We have generated tools for pathway mapping, reliable quantification of chemicals, and network analysis. Recently, we have focused on efforts to harmonize our data in a cumulative database. We have used these methods for deep metabolic phenotyping in human research through collaborations with clinical investigators studying a broad spectrum of human diseases, including lung, cardiovascular, renal, liver, endocrine, neurologic, infectious disease and cancer.

Exposomics
In our early work with human metabolomics, it became clear that metabolomics data is rich in information about environmental exposures and metabolic responses to them. We have developed network approaches to understand the impacts of complex environmental exposures on biological systems, and we have developed experimental approaches to test and apply these network toxicology models to low-level environmental exposures. We maintain ongoing collaborations with epidemiologists and environmental health experts to study metabolic changes as they relate to environmental exposures on a systems level.

Metals Toxicology
Many past and present projects of the lab have been in the area of metals toxicology. We have previously investigated both cadmium and manganese as environmental stressors to study physiological changes and cellular responses using combined analyses of the metabolome, transcriptome, redox proteome, and redox systems. Currently, we are investigating sensitization to cadmium as a result of early life viral infection, the role of vanadium exposures in lung fibrosis, the role of prenatal heavy metal exposures on lung development, and the influence of dietary metal chelators on heavy metal exposures.
