Publisher Summary This chapter discusses the current status of the investigations on the
hormonal regulation of oocyte growth and maturation in fish. Pituitary gonadotropins are of …

Chemicals released into the environment potentially disrupt the endocrine system in wild
animals and humans. Developing organisms are particularly sensitive to estrogenic chemicals. …

The mineralocorticoid receptor (MR) is descended from a corticoid receptor (CR), which has
descendants in lamprey and hagfish, cyclostomes (jawless fish), a taxon that evolved at the …

In utero exposure to bisphenol-A (BPA) at doses relevant to human consumption has been
reported to accelerate weight gain and puberty in female mice, but the effect of low dose BPA …

Reproductive tract development is influenced by estrogen. The aim of this study was to
determine the effects of an environmental estrogenic chemical bisphenol-A (BPA) on prenatal …

Globally, feminization responses in wild male freshwater fish are caused by exposure to
estrogenic chemicals, including natural and synthetic estrogens, contained in effluents from …

Endocrine disrupting chemicals can affect normal hormone dependent processes through
numerous mechanisms, including ligand mimicky. 17β-Trenbolone (TB), a pharmaceutical, …

Translational activation of dormant cyclin B1 mRNA stored in oocytes is a prerequisite for
the initiation or promotion of oocyte maturation in many vertebrates. Using a monoclonal …

Exposure to estrogenic chemicals discharged into the aquatic environment has been shown
to induce feminization in wild freshwater fish and although fish species have been reported …

Protein synthesis of cyclin B by translational activation of the dormant mRNA stored in
oocytes is required for normal progression of maturation. In this study, we investigated the …
