TABLE 2

Partial list of enzyme transcripts (including some Ests) upregulated in Oat3-knockout kidney

Multiple probes for Phase I (i.e., CYP2b10 isoform 1) and Phase II (i.e., UGT2B5) drug metabolizing enzyme displayed similar levels of expression change. The elevated expression observed for 3-oxo-5-alpha-steroid 4-dehydrogenase 2 suggests enhanced enzymatic metabolism for steroid hormones, many of which are known OAT3 substrates.
