Genistein and estradiol have common and specific impacts on the sea bass (Dicen...
Pinto, Patricia IS; Andrade, André; Moreira, Catarina; Zapater, Cinta; Thorne, Michael A.S.; Santos, Soraia; Estêvão, M. Dulce; Gomez, AnaTeleost fish scales play important roles in animal protection and homeostasis. They can be targeted by endogenous estrogens and by environmental estrogenic endocrine disruptors. The phytoestrogen genistein is ubiquitous in the environment and in aquaculture feeds and is a disruptor of estrogenic processes in vertebrates. To test genistein disrupting actions in teleost fish we used a minimally invasive approach ...
Photoperiodic Modulation of Circadian Clock and Reproductive Axis Gene Expressi...
Martins, Rute S. T.; Gomez, Ana; Zanuy, Silvia; Carrillo, Manuel; Canario, Adelino V. M.The acquisition of reproductive competence requires the activation of the brain-pituitary-gonad (BPG) axis, which in most vertebrates, including fishes, is initiated by changes in photoperiod. In the European sea bass long-term exposure to continuous light (LL) alters the rhythm of reproductive hormones, delays spermatogenesis and reduces the incidence of precocious males. In contrast, an early shift from long ...
