Figure 5.
Sertraline exposed mice have increased expression of the serotonin transporter protein (5-HTT). PCR was performed on midbrain and cerebral cortex homogenates obtained from control and SSRI-exposed mice (gray bars). Expression of the serotonin transporter protein and serotonin receptor 5-HT2B were quantified and compared to control mice. Midbrain and cerebral cortex expression of 5-HTT mRNA is significantly increased in SSRI-exposed male mice compared to control mice (a). Midbrain 5-HTT expression is significantly increased compared to cortex (a). No differences were observed in expression of 5-HT2B receptors between brain regions or between sertraline exposed mice and control mice (b). N = 7–10 mice from 5–10 litters. *P<0.05 versus control. **P<0.05 versus cortex.
