ESR1 mediates estrogen-induced feminization of genetic male Chinese soft-shelled turtle†.

Exogenous estrogen have shown their feminization abilities during the specific sex differentiation period in several reptiles. However, the specific regulatory mechanism and downstream regulatory genes of estrogen remain elusive. In the present study, 17β-estradiol (E2), as well as drugs of specific antagonists and/or agonists of estrogen receptors, were employed to figure out the molecular pathway involved in the E2-induced feminization in Chinese soft-shelled turtles, an important aquaculture species in China.
