Journal ArticleDOI
Diel cycling hypoxia enhances hypoxia-tolerance in rainbow trout (Oncorhynchus mykiss): evidence of physiological and metabolic plasticity
Kenneth Williams,Alicia A. Cassidy,Christine E. Verhille,Simon G. Lamarre,Tyson J. MacCormack +4 more
TL;DR: Hypoxia tolerance is a plastic trait in fish, and a putatively sensitive species can remodel its physiology and metabolism to effectively cope with diel cycling hypoxia.
Journal ArticleDOI
Adjustments of Protein Metabolism in Fasting Arctic Charr, Salvelinus alpinus.
TL;DR: This study is the first to measure both KS and the enzymatic activity of protein degradation in the same fish, allowing us to examine the apparent contribution of different protein degradation pathways to protein turnover in various tissues.
Journal ArticleDOI
Protein synthesis is lowered by 4EBP1 and eIF2-α signaling while protein degradation may be maintained in fasting, hypoxic Amazonian cichlids Astronotus ocellatus.
Alicia A. Cassidy,William R. Driedzic,Derek Felipe Campos,Waldir D. Heinrichs-Caldas,Vera Maria Fonseca de Almeida-Val,Adalberto Luis Val,Simon G. Lamarre +6 more
TL;DR: It was determined for the first time in fish that a decrease in protein synthesis during hypoxia is likely controlled by signaling molecules (4EBP1 and eIF2-α, and not simply due to a lack of ATP), and regulated by cell signaling pathways.
Journal ArticleDOI
Effects of fasting and refeeding on protein and glucose metabolism in arctic charr.
Alicia A. Cassidy,Pierre U. Blier,Nathalie R. Le François,Patrick Dionne,Pier Jr Morin,Simon G. Lamarre +5 more
TL;DR: It is shown that miRNAs (miR-29a and miR-223) could be involved in fish glycogen homeostasis during the early stages of refeeding, which provides a deeper understanding of the molecular mechanisms regulating growth in fish.
Journal ArticleDOI
Activation of oxygen-responsive pathways are associated with altered protein metabolism in Arctic char exposed to hypoxia
TL;DR: It is shown that protein metabolism in Arctic char is altered in a tissue-specific fashion during graded hypoxia, which is in accordance with the responses of the three major Hypoxia-sensitive pathways (HIF, UPR and mTOR).
