A related model Oct1 (-/-) rats have increased exposure to specific substrates
This model contains a biallelic deletion within the Slc22a2 solute carrier family 22 (organic cation transporter), member 2, encoding for the basolateral hepatocyte uptake transporter OCT2.
Oct2 is involved in disposition and excretion through its role in xenobiotic uptake in the basolateral membrane of the liver. Polymorphisms within the gene also have clinical relevance - making this a useful model for studying drug-drug interations, toxicity and metabolism in the liver.
