Imposex in gastropods from Venezuela
Ciencias Marinas, 2007 The imposex phenomenon is a superimposition of male characters on gastropod females due to exposure to tributyltin (TBT). There have been no previous reports of this phenomenon in the southern Caribbean, which is inhabited by some edible and ...

Imposex in Stramonita haemastoma from coastal sites of Cartagena, Colombia [PDF]
Brazilian Journal of Biology, 2017 Imposex is the development of male sexual characteristics caused by the toxic effects of some chemicals that acts as an endocrinal disruptor. Antifouling paints contain these chemicals.

Imposex in endemic volutid from Northeast Brazil (Mollusca: Gastropoda) [PDF]
Brazilian Archives of Biology and Technology, 2008 Imposex is characterized by the development of masculine sexual organs in neogastropod females. Almost 120 mollusk species are known to present imposex when exposed to organic tin compounds as tributyltin (TBT) and triphenyltin (TPT). These compounds are

RXR Expression in Marine Gastropods with Different Sensitivity to Imposex Development. [PDF]
Sci Rep, 2020 AbstractThe superposition of male sexual characteristics in female marine gastropods (imposex) represents one of the clearest ecological examples of organotin-mediated endocrine disruption. Recent evidences suggest that signaling pathways mediated by members of the nuclear receptor superfamily, RXR and PPARγ, are involved in the development of this ...

Mapping molluscan endocrinology: a systematic and critical appraisal. [PDF]
Biol Rev Camb Philos SocABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Prioritising research on endocrine disruption in the marine environment: a global perspective. [PDF]
Biol Rev Camb Philos SocABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Brazilian Journal of Oceanography, 2004 The use of antifouling paints containing the biocide compound tributyltin (TBT) has been shown as an inductor of imposex in neogastropods mollusks. Imposex is characterized by the development of male features in females, mainly the appearance of a no ...

Brazilian Journal of Oceanography, 2006 Marine organisms are affected by organotin compounds due to the cumulative, deleterious effects of these latter. The most evident and well known consequence of organotin contamination is imposex, a hormonal disruption that causes a superimposition of ...

Imposex in pre-pollution times. Is TBT to blame? [PDF]
Marine Pollution Bulletin, 2006 Imposex is known to be induced by TBT at a very low ambient concentration, just a few nanogram per litre, and its development seems dose-dependent. However, the causal, exclusive link between TBT and imposex still need to be assessed in all species where imposex has been reported, becoming one of the most controversial issues of marine biology in the ...
