Effects of Diethylstilbestrol on Zebrafish Gonad Development and Endocrine Disruption Mechanism.

ABSTRACT: Environmental estrogen is a substance that functions as an endocrine hormone in organisms and can cause endocrine system disruption. A typical environmental estrogen, diethylstilbestrol (DES), can affect normal sexual function and organism development. However, even though the effects of different exposure stages of DES on the endocrine system and gonadal development of zebrafish juveniles are unknown, sex determination is strongly influenced by endocrine-disrupting chemicals (EDCs). From 10-90 days post fertilization (dpf), juvenile zebrafish were exposed to DES (100 and 1000 ng/L) in three different stages (initial development stage (IDS), 10-25 dpf; gonadal differentiation stage (GDS), 25-45 dpf and gonadal maturity stage (GMS), 45-60 dpf). Compared with that of IDS and GMS, the growth
