TLDR
The focus then shifts to selected aspects of hormonal regulation of carbohydrate metabolism and dietary carbohydrates and their variable effects on glycogen and glucose turnover, and the correlation of dietary carbohydrates with fish health.Abstract:
The utilisation of dietary carbohydrates and their effects on fish metabolism are reviewed. Details on how dietary carbohydrates affect growth, feed utilisation and deposition of nutrients are discussed. Variations in plasma glucose concentrations emphasizing results from glucose tolerance tests, and the impact of adaptation diets are interpreted in the context of secondary carbohydrate metabolism. Our focus then shifts to selected aspects of hormonal regulation of carbohydrate metabolism and dietary carbohydrates and their variable effects on glycogen and glucose turnover. We analyse the interaction of carbohydrates with other nutrients, especially protein and protein sparing, and de novo synthesis of lipids, and finish by discussing the correlation of dietary carbohydrates with fish health.read more

Starvation–refeeding causes cellular stress responses in the gut and liver of Masu salmon Oncorhynchus masou masou
Hidehiro Kondo,Hiroaki Sano,Yuanyuan Wang,Junya Kawase,Eiji Shimanoki,Walissara Jirapongpairoj,Reiko Nozaki,Ikuo Hirono +7 more
TL;DR: Gene expression profiles during the transition from fasting to refeeding were investigated in the gut and liver of Masu salmon Oncorhynchus masou masou to suggest that the change in nutritional status from fasting to refeedsing is accompanied by cellular stress.

cDNA sequence and tissue expression analysis of glucokinase from liver of grass carp (Ctenopharyngodon idella )
TL;DR: A full-length cDNA coding glucokinase was cloned from the liver of grass carp by reverse transcriptase-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends methods and the result shows that the expression level of GK mRNA in liver was significantly higher than in mesenteric adipose tissue, spleen and brain.

The effect of dietary dextrin levels on growth performance, body composition and hepatosomatic index in juvenile Siberian sturgeon, Acipenser baerii
TL;DR: In this article, the ability of Acipenser baerii in utilizing carbohydrate (dextrin) as a non-protein energy source substituted with animal oil was investigated and five diets were formulated including 0, 5, 10, 15 and 20% of dextrin.

Taurine alleviates endoplasmic reticulum stress, inflammatory cytokine expression and mitochondrial oxidative stress induced by high glucose in the muscle cells of olive flounder (Paralichthysolivaceus).
TL;DR: In this paper , the effects of taurine on endoplasmic reticulum stress, inflammatory cytokine expression and mitochondrial oxidative stress induced by high glucose in primary cultured muscle cells of olive flounder (Paralichthys olivaceus) were evaluated.

Cortisol in teleosts: dynamics, mechanisms of action, and metabolic regulation
TL;DR: This review attempts to delineate common themes on the physiological and metabolic roles of cortisol in teleost fishes and to suggest new approaches that might overcome some of the inconsistencies on the role of this multifaceted hormone.

Stress responses and disease resistance in salmonid fish: Effects of chronic elevation of plasma cortisol
TL;DR: It is shown, by means of intraperitoneal implantation of cortisol, that chronic elevation of plasma cortisol levels in the brown trout results in a dose-dependent increase in mortality due to common bacterial and fungal diseases.

What if Minkowski had been ageusic? An alternative angle on diabetes.
TL;DR: It is suggested that the phenomena of insulin resistance and hyperglycemia might be more readily understood if viewed in the context of underlying abnormalities of lipid metabolism.

Pancreatic beta-cells are rendered glucose-competent by the insulinotropic hormone glucagon-like peptide-1(7-37)
TL;DR: It is reported here that GLP-1 confers glucose sensitivity to glucose-resistant p-cells, a phenomenon the authors term glucose competence, which is similar to membrane depolarization, the generation of action potentials, and Ca2+ influx, events that are known to trigger insulin secretion.

Glucose-6-phosphate dehydrogenase: a "housekeeping" enzyme subject to tissue-specific regulation by hormones, nutrients, and oxidant stress.
TL;DR: The central question of this review is “How can the G6PDH gene be constitutively expressed in some tissues while displaying adaptive regulation in others when there exists a single transcription unit for the gene?”
