Solute Carrier Organic Anion Transporter Family, Member 1B2 (SLCO1B2)
Slco1b2 mice were fertile, developed normally, and exhibited no overt phenotypic abnormalities. Expression of Oatp1a4 and Oatp2b1 but not Oatp1a1 was greater in female Slco1b2 mice, but expression of other non-OATP transporters did not significantly differ between wild-type and Slco1b2 male mice.
Total bilirubin level was elevated by 2-fold in the Slco1b2 mice despite the fact that liver enzymes ALT and AST were normal. Pharmacological characterization was carried out using two prototypical substrates of human OATP1B1 and -1B3, rifampin and pravastatin. This is the first report of altered drug disposition profile in the Slco1b2 knockout mice and suggests the utility of this model for understanding the in vivo role of hepatic OATP transporters in drug disposition.
