Research Description

The central theme of my research is to promote rational cancer therapy and drug development by better understanding the clinical pharmacology of anticancer agents, that is, how the body handles a drug (i.e., pharmacokinetics) and how a drug acts on the body (i.e., pharmacodynamics). We employ an integrated translational research approach that leverages preclinical pharmacology studies, pharmacokinetic modeling, and clinical trials to mechanistically understand and quantitatively predict pharmacokinetics and pharmacodynamics of anticancer drugs in patients.

Physiologically based pharmacokinetic modeling of the human central nervous system (CNS) pharmacokinetics: Insufficient penetration of potentially effective chemotherapeutic agents across the human blood-brain barrier (BBB) is a huge hurdle to successful treatment of brain cancer. Mechanistic understanding and early prediction of drug BBB penetration is of paramount importance to rational drug development and treatment for brain cancer. Given the fact that the rate and extent of drug BBB penetration is determined by not only drug properties but also biological system characteristics, prediction of human BBB permeability from preclinical in vitro or animal models is complicated by biological system differences. Hence, the development of innovative approaches is imperative. The in vitro-in vivo extrapolation-physiologically based pharmacokinetic (IVIVE-PBPK) model offers a unique platform that allows simultaneous incorporation of drug- and system-specific parameters into a pharmacokinetic model and enables a priori prediction of individual in vivo kinetic processes based on mechanistic scaling of in vitro data (e.g., in vitro enzyme and transporter kinetics). Our research has been focused on the development of innovative CNS PBPK models for mechanistic prediction of heterogeneous penetration of anticancer drugs into the human brain and brain tumors. The obtained quantitative information is of enormous value to rational development of effective therapies for brain cancer, as early knowledge of drug levels in the human brain and brain tumors is critical to the decision-making regarding further clinical development and design of improved drugs and dosing regimens.

Metabolomics: Novel metabolomics technologies allow high-throughput assessment of a large number of endogenous metabolites, thus providing powerful tools for mapping biochemical pathways implicated in diseases and in response to drug treatment. We have developed a LC-MS/MS based targeted metabolomics platform that is capable of quantitative profiling of ~ 300 endogenous metabolites involved in major human metabolic pathways. In addition, we have developed metabolic flux analyses with isotope-labeled tracers (including [1,2-13C]glucose, [U-13C]glucose, [U-13C]glutamine, [2,3,3-2H]Serine) to specifically determine metabolic flow in the central carbon metabolism (including glycolysis, pentose phosphate pathway, and tricarboxylic acid cycle) and one-carbon metabolism pathways. Our laboratory has become one of the premier institutional-based metabolomics laboratories in the nation, which provides critical metabolomics support for a number of national funded research projects and multi-center clinical trials.
