Toxicities from xenobiotic exposures are a significant burden on human health. These exposures occur both intentionally (drugs and dietary supplements) and unintentionally (environmental contamination and naturally occurring toxins), and there are several factors in individual variability that determine who is at greater risk for these toxicities. Clarke's laboratory seeks to address two fundamental research questions regarding populations at risk for toxicities:
- Precision medicine: This project investigates how perturbations in two or more factors in drug absorption, distribution, metabolism, and excretion affect drug exposures and toxicities.
- Toxicities in progressive nonalcoholic fatty liver disease (NAFLD): NAFLD is the most common liver disease in the United States that progresses through multiple stages including simple fatty liver, nonalcoholic steatohepatitis (NASH), cirrhosis, and hepatocellular carcinoma. This project seeks to identify xenobiotics that can drive the progression of NAFLD and the molecular mechanisms behind each toxicity.
Results from this work will help to inform clinicians, drug companies and regulators regarding at-risk populations for xenobiotic toxicities.
