Fig 2. The expressions of tshβ (A) and crh (B) and nis (C) of zebrafish larvae were detected by real-time PCR after exposure to 0, 40, 100, 200, 400 μg/L of DEHP at 168 hpf.

The results were means ± SEM of three replicate samples. Significant difference between exposure groups and the control groups was indicated by *P < 0.05 and **P < 0.01.
