Fig 3. The expressions of nkx2.1 (A) and pax8 (B) and tg (C) were measured by real-time PCR after exposure to 0, 40, 100, 200, 400 μg/L of DEHP at 168 hpf in zebrafish larvae.

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 and ***P<0.001.
