FIG. 8.

Effects of PFDA on mouse Oatp1a1, 1a4, and 1b2, as well as Ntcp mRNA expression in wild-type and Nrf2-null mice. The mouse treatments are separated into four groups: Nrf2^(+/+) + CONT, wild-type mice treated with the vehicle, propylene glycerol:water (1:1, vol/vol); Nrf2^(+/+) + PFDA, wild-type mice treated with PFDA at dose 80 mg/kg of body weight; Nrf2^(−/−) + CONT, Nrf2-null mice treated with the vehicle; Nrf2^(−/−) + PFDA, Nrf2-null mice treated with PFDA at dose 80 mg/kg. The mice were given a single i.p. administration. After 2 days, livers were removed. Total RNA from treated mouse livers was analyzed by the bDNA assay. All data are expressed as mean ± SEM of five mice for each treatment. Asterisk indicates statistically significant difference between treated and control mice (p < 0.05).
