Dietary fatty acids and flight-training influence the expression of the eicosanoid hormone prostacyclin in songbirds
Comp Biochem Physiol A Mol Integr Physiol. 2023 Dec 6;288:111561. doi: 10.1016/j.cbpa.2023.111561. Online ahead of print.ABSTRACTDiet shifts can alter tissue fatty acid composition in birds, which is subsequently related to metabolic patterns. Eicosanoids, short-lived fatty acid-derived hormones, have been proposed to mediate these relationships but neither baseline concentrations nor the responses to diet and exercise have been measured in songbirds. We quantified a stable derivative of the vasodilatory eicosanoid prostacyclin in the plasma of male European Starlings (Sturnus vulgaris, N = 25) fed semisynthetic diets with...

Understanding olfactory and behavioural responses to dietary cues in age-1 lake sturgeon Acipenser fulvescens
In this study we used electrophysiological and behavioural techniques to evaluate olfactory detection and behaviour in juvenile lake sturgeon Acipenser fulvescens in response to hatchery- and natural dietary cues. We hypothesized that electro-olfactogram (EOG) and behavioural responses would be dependent on diet type. We predicted that inhibition of the phospholipase C/inositol 1,4,5-triphosphate (PLC/IP3) secondary transduction pathway would reduce EOG responses to dietary cues and, inhibition of the adenylyl cyclase/adenosine 3,5-cyclic monophosphate (cAMP) pathway, would have no effect. Furthermore, we predicted a stron...

Cortisol enhances aerobic metabolism and locomotor performance during the transition to land in an amphibious fish
Comp Biochem Physiol A Mol Integr Physiol. 2023 Dec 1:111558. doi: 10.1016/j.cbpa.2023.111558. Online ahead of print.ABSTRACTAmphibious fishes on land encounter higher oxygen (O2) availability and novel energetic demands, which impacts metabolism. Previous work on the amphibious mangrove killifish (Kryptolebias marmoratus) has shown that cortisol becomes elevated in response to air exposure, suggesting a possible role in regulating metabolism as fish move into terrestrial environments. We tested the hypothesis that cortisol is the mechanism by which oxidative processes are upregulated during the transition to land in amphi...

Exploring transcriptional and post-transcriptional epigenetic regulation of crf and 11 βhsd2 in rainbow trout brain during chronic social stress
Comp Biochem Physiol A Mol Integr Physiol. 2023 Dec 1:111557. doi: 10.1016/j.cbpa.2023.111557. Online ahead of print.ABSTRACTUsing dominance hierarchies in juvenile rainbow trout (Oncorhynchus mykiss) as a model of chronic social stress in fish, we explored whether epigenetic transcriptional and post-transcriptional mechanisms are involved in the gene expression of corticotropin-releasing factor (crf) and 11β-hydroxysteroid dehydrogenase (11βhsd2), key factors involved in the regulation of the endocrine stress axis response. In juvenile rainbow trout pairs, subordinate individuals display sustained elevation of circulati...
