Our project asks the following questions
Which enzymes metabolize PAHs?
We use activity-based protein profiling to identify which enzymes metabolize different PAHs. We then determine the prevalence (frequency) of these enzymes in the human population.
What are the rates of PAH metabolism in human tissues?
The goal of this work is to identify the rate at which different PAHs are metabolized by different enzymes. We can do this using in vitro tests to identify the rate of metabolism. Then, we can look at how the rates change based on the enzyme being used.
Can computational models be used to predict internal concentrations of PAHs?
As we identify rates of PAH metabolism, we can use these rates to build a computer model. We can add in the prevalence of these enzymes in the human population to better understand how PAH metabolism rates may change between people (intra-individual variability) and how they may change based on the exposure and dose.
