Highlights • ER and ERR transcription levels were unaffected in Marisa cornuarietis exposed to 17β-estradiol or 4-tert-Octylphenol. • The mollusc ER protein interacts with the phytoestrogen genistein in transfected HEK-293 cells. • The mollusc

Laboratory populations of freshwater Keeled rams horn snails (Planorbis carinatus Muller, 1774) were exposed as adults to measured concentrations of ibuprofen free base (CAS number 15687-27-1) for up to 21 d using methanol (0.1 mL/L) as a carrier sol

The freshwater prosobranch ampullarid Marisa cornuarietis Linnaeus 1758, also known as the apple snail, is used in many tropical countries as a biological control agent for molluscs hosting the trematode known to cause intestinal schistosomiasis (Poi

Concern over endocrine disrupters in coastal ecosystems has stimulated global efforts to understand their potential impacts on fish and invertebrate communities. Given that marine crustaceans are sensitive to the effects of alkylphenols and other xen

Sexual differentiation in fish occurs after hatching during early life-stages and is believed to be a time when the gonad has a heightened sensitivity to disruption by chemicals that mimic hormones. In this study fathead minnows (Pimephales promelas)

Life-cycle effects of a reference ecdysteroid, 20-hydroxyecdysone (20-HEC) and the model xenoestrogen, diethylstil-bestrol (DES) in Tisbe battagliai (Crustacea, Copepoda, Harpacticoida) have been evaluated. T. battagliai is a sexually reproducing spe

Given recent reports suggesting that natural and synthetic steroids (namely, oestradiol, oestrone and ethynylestradiol) may be present in sewage effluent at levels which may impact on fish, it is pertinent to extend the ecological hazard evaluation f

It has been claimed that bisphenol A (BPA) induces superfeminization in the freshwater gastropod, Marisa cornuarietis. To explore the reproducibility of prior work, here we present results from a three-laboratory study, the objectives of which were t

P450 17α-hydroxylase,17,20-lyase (P450c17) is a key steroidogenic enzyme in the production of androgens and, therefore, is also indispensable for the production of oestrogens (that are produced from the aromatisation of androgens). In this study, P4
