Endocrine and reproductive endpoints of Notothenia rossii and N. coriiceps: A baseline study for ecotoxicological monitoring in Antarctic waters
(Pergamon-Elsevier Science Ltd, 2019-08)
Pollution threats Antarctica and scientists blame xenobiotics and anthropic activities. Yet little is known about their effect on Antarctic ichthyofauna. Accordingly, we investigated the endocrine system of male fish ...
Disruption of vitellogenin gene function in adult honeybees by intra-abdominal injection of double-stranded RNA
(2003-01-20)
Abstract
Background
The ability to manipulate the genetic networks underlying the physiological and behavioural repertoires of the adult honeybee worker (Apis mellifera) is ...

Insulin-like peptide genes in honey bee fat body respond differently to manipulation of social behavioral physiology
(COMPANY OF BIOLOGISTS LTD, 2011)
Nutrient sensitive insulin-like peptides (ILPs) have profound effects on invertebrate metabolism, nutrient storage, fertility and aging. Many insects transcribe ILPs in specialized neurosecretory cells at changing levels ...
Endocrine disruption in the sub Antarctic fish Patagonotothen tessellata (Perciformes, Notothenidae) from Beagle Channel associated to anthropogenic impact
(Elsevier, 2021-10)
Situated in the sub-Antarctic region, Beagle Channel represents a unique marine ecosystem due to the connection between the Pacific and the Atlantic Oceans, and its proximity to the Antarctic Peninsula. Ushuaia city, the ...

Hormonal control and target genes of ftz-f1 expression in the honeybee Apis mellifera: a positive loop linking juvenile hormone, ftz-f1, and vitellogenin
(2019-02-01)
Ftz-f1 is an orphan member of the nuclear hormone receptor superfamily. A 20-hydroxyecdysone pulse allows ftz-f1 gene expression, which then regulates the activity of downstream genes involved in major developmental ...
Induction of vitellogenin-like lipoproteins in the mussel Aulacomya ater under exposure to 17β-estradiol
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2012-12)
The mussel Aulacomya ater was exposed to 17β-estradiol (E2) (0, 1, 100 µg L-1) for 21 days with 4 sampling periods to evaluate how these organisms deal with exogenous estrogenic compounds. In addition, 2 concentrations of ...
