Figure 5: Expression of efflux transporter genes in pregnant mice treated with TCPOBOP. Hepatic mRNA expression of efflux transporters was quantified in virgin and pregnant mice treated with vehicle or TCPOBOP. Data were normalized to vehicle-treated virgin controls (set to 1.0) and presented as mean relative expression ± SE (n = 6 − 9). Black bars represent vehicle-treated mice, and grey bars represent TCPOBOP-treated mice. Asterisks (*) represent differences (P≤0.05) compared with vehicle-treated virgin mice. Daggers (†) represent differences (P≤0.05) compared with vehicle-treated pregnant mice.
