The overall objective of this dissertation is to study the in vivo function of microsomal cytochrome P450 monooxygenases (P450s), which metabolize numerous drugs, chemical carcinogens, environmental pollutants, as well as endogenous signaling molecules such as steroid hormones and eicosanoids. The major research tool of this study involves the development of transgenic and knockout mouse models. The specific aims are 1) to study the in vivo function of NADPH-cytochrome P450 reductase (CPR) and CPR-dependent enzymes using a mouse model with a reversible hypomorphic Cpr gene; 2) to study the in vivo function of CYP2A13 with a CYP2A13- transgenic model; and 3) to generate a novel Cyp2a-2b-2f-2g-2s-null mouse model as the background strain for CYP2A13-humanized model.
