Fig. 3. Effects of TDCIPP on relative expression of genes involved in GH/IGF axis of silver carp larvae at 7, 14 and 28 days of exposure. Values are the mean ± SD (n = 6). The different lower-case above bars indicate values that are significant differences (P<0.05) within a specific concentration (0, 0.05, 0.5, 5, 50 μg/L) of TDCIPP treatment and between different exposure time (7, 14, 28 days). The different upper-case above bars indicate values that are significant differences (P<0.05) within a specific exposure time (7, 14, 28 days) of TDCIPP treatment and between different concentration of TDCIPP treatment (0, 0.05, 0.5, 5, 50 μg/L).
