Evidence for two distinct functional glucocorticoid receptors in teleost fish.
TLDR
Results indicate that these two GR sequences encode for two functionally distinct GRs acting as ligand-inducible transcription factors in rainbow trout.
11-deoxycorticosterone is a potent agonist of the rainbow trout (Oncorhynchus mykiss) mineralocorticoid receptor.
The teleost fish are thought to lack the mineralocorticoid hormone aldosterone but possess mineralocorticoid receptor (MR) homologs. Here we describe the characterization of two rainbow trout
Evolution of the corticosteroid receptor signalling pathway in fish.
Corticosteroid receptors involved in stress regulation in common carp, Cyprinus carpio.
TLDR
Transactivation studies show that the carp GRs and MR have comparable affinity for cortisol; the MR has significantly higher sensitivity to DOC, and this favours a role for DOC as MR ligand in fish physiology, and suggest telencephalon as a first line cortisol target in stress.
The ABC transporter gene family of Daphnia pulex
TLDR
A genome-wide survey of ABC proteins of Daphnia pulex is reported, providing for the first time information on ABC proteins in crustacea, a primarily aquatic arthropod subphylum of high ecological and economical importance.
Different sensitivity to organophosphates of acetylcholinesterase and butyrylcholinesterase from three‐spined stickleback (Gasterosteus aculeatus): Application in biomonitoring
TLDR
Because stickleback AChE and BChE differed strongly in their in vitro sensitivity and their response in the field, these enzymes should be considered separately in studies with fish.
Potential use of cholinesterase in monitoring low levels of organophosphates in small streams: Natural variability in three‐spined stickleback (Gasterosteus aculeatus) and relation to pollution
TLDR
The reported characteristics of ChE and its natural variability in stickleback represent baseline data for its use in the monitoring of OP contamination of small streams.
Effects of parathion on acetylcholinesterase, butyrylcholinesterase, and carboxylesterase in three‐spined stickleback (Gasterosteus aculeatus) following short‐term exposure
TLDR
The sensitivity of butyrylcholinesterase (BChE) toward the inhibition by the organophosphorus insecticide (OP) parathion‐ethyl was compared with that of other esterases in the fish three‐spined stickleback to suggest the potential application ofstickleback BChE as a biomarker of OP exposure.
