Environmental estrogens have been shown to affect aspects of fish behavior that could potentially impact on wild populations, but the physiological mechanisms underpinning these effects are unknown. Using small colonies zebrafish (Danio rerio), we evaluated impacts estrogen exposure aggression dominant males, associated implications for their social status and reproductive success, signaling mechanisms. The males exposed 17α-ethinylestradiol (EE(2); 10 ng/L nominal) was reduced...
In anuran ovaries, 5S rDNA is regulated transcriptionally by transcription factor IIIA (TFIIIA), which upon transcription, binds rRNA, forming 7S RNP. rRNA can be stockpiled also in the form of 42S RNP bound to 42sp43. The aim present study was assess differential transcriptional regulation and associated proteins thicklip gray mullet (Chelon labrosus) gonads. Up 75% total RNA from ovaries rRNA. qPCR quantification expression, gonads histologically sexed individuals different geographical...
Exposure of marine animals to certain organic and metal pollutants is thought enhance reactive oxygen species (ROS) production with concomitant alterations antioxidant defence mechanisms. Some these cause peroxisome proliferation, a process resulting also in possible enhanced ROS. The aim this study was investigate the effects two xenobiotics, benzo(a)pyrene (B(a)P) di(2-ethylhexyl)phthalate (DEHP), as well cadmium (Cd), on peroxisomal enzymes volume density digestive gland mussel, Mytilus...
The aim of this work was to assess possible effects the Prestige oil spill on reproduction parameters mussels along Galician and Bay Biscay coast. Studied endpoints included sex ratio, gonad histology vitellogenin-like proteins using alkali-labile phosphate (ALP) method. A high prevalence haemocytic infiltration follicles severe oocyte atresia found in most localities April 2003. Spawning gonads were observed impacted populations same sampling. In 2004 mature small sized observed. No...
Abstract The aim of the present work was to study effects peroxisome proliferator dibutylphthalate (DBP) and xenoestrogen 17α‐ethynylestradiol (EE 2 ) on liver peroxisomes, reproduction, development zebrafish ( Danio rerio ). In experiment 1, newly fertilized eggs were exposed for five weeks, covering entire period sexual determination, nominal concentrations 25 100 μg/L DBP 5 EE . 2, adult female 15 d 500 , afterward, they paired with untreated males in resultant offspring. Ethynylestradiol...
