Nutritional programming in Nile tilapia <i>(</i>Oreochromis<i> </i>niloticus<i>)</i>: Effect of low dietary protein on growth and the intestinal microbiome and transcriptome

PLOS ONE, 18(10).

By: C. Deck n, S. Salger n, H. Reynolds n, M. Tada n, M. Severance n, P. Ferket n , H. Egna *, M. Fatema *, S. Haque *, R. Borski n

TL;DR: Results suggest protein restriction for up to 14 days early in development leads to enhanced growth and feed efficiency with minimal effects on gut microbes or intestinal function, while Protein restriction beyond this period appears detrimental to fish growth and health as underscores by expression of disease related genes and higher mortality rates.

JOURNAL OF ENDOCRINOLOGY, 253(1), 13–25.

By: C. Deck n, J. Mankiewicz n  & R. Borski n

Contributors: C. Deck n, J. Mankiewicz n  & R. Borski n

author keywords: leptin; insulin; glucagon; Brockmann bodies; tilapia
MeSH headings : Animals; Blood Glucose / metabolism; Cells, Cultured; Fish Proteins / genetics; Fish Proteins / metabolism; Gene Expression Regulation; Glucagon / genetics; Glucagon / metabolism; Glucose / metabolism; Hepatocytes / metabolism; Insulin / genetics; Insulin / metabolism; Insulin Secretion; Leptin / genetics; Leptin / metabolism; Male; RNA, Messenger / genetics; RNA, Messenger / metabolism; Reverse Transcriptase Polymerase Chain Reaction; Signal Transduction / genetics; Tilapia / genetics; Tilapia / metabolism; Time Factors
TL;DR: Data indicate that a leptin-insulin axis may be conserved among vertebrates and is thus essential for regulating nutrient balance but that the relationship is likely much more dynamic in teleosts as glycaemia is not as tightly regulated as it is in mammals. (via Semantic Scholar)

Epinephrine and glucose regulation of leptin synthesis and secretion in a teleost fish, the tilapia (Oreochromis mossambicus)

GENERAL AND COMPARATIVE ENDOCRINOLOGY, 302.

By: J. Mankiewicz n , C. Deck n, J. Taylor n, J. Douros* & R. Borski n

Contributors: J. Mankiewicz n , C. Deck n, J. Taylor n, J. Douros* & R. Borski n

author keywords: Epinephrine; Tilapia; Glucose; Leptin; Stress
MeSH headings : Animals; Epinephrine; Glucose; Leptin; Liver; Tilapia
TL;DR: The results of this study demonstrate LepA is negatively regulated by rises in extracellular glucose at the level of the hepatocyte but stimulated by hyperglycemia in vivo, and epinephrine increases LepA. (via Semantic Scholar)

Naked mole-rats reduce the expression of ATP-dependent but not ATP-independent heat shock proteins in acute hypoxia

JOURNAL OF EXPERIMENTAL BIOLOGY, 222(22).

By: V. Nguyen*, C. Deck n & M. Pamenter *

author keywords: Molecular chaperone; Proteostasis; Metabolic rate suppression; Unfolded protein response
MeSH headings : Adaptation, Physiological; Animals; Gene Expression Regulation; Heat-Shock Proteins / genetics; Heat-Shock Proteins / metabolism; Hypoxia / physiopathology; Mole Rats / genetics; Mole Rats / metabolism; Molecular Chaperones; Proteostasis
TL;DR: In acute hypoxia, the regulation of heat shock proteins in naked mole-rats indicates prioritization of energy conservation over proteostasis. (via Semantic Scholar)

The activity of the rectal gland of the North Pacific spiny dogfish Squalus suckleyi is glucose dependent and stimulated by glucagon-like peptide-1

JOURNAL OF COMPARATIVE PHYSIOLOGY B-BIOCHEMICAL SYSTEMIC AND ENVIRONMENTAL PHYSIOLOGY, 187(8), 1155–1161.

By: C. Deck*, W. Anderson *, J. Conlon * & P. Walsh *

author keywords: Rectal gland; Glucose transporter; Glucagon-like peptide; Elasmobranchs; Dogfish

TL;DR: Perfusion with dogfish GLP-1, but not dogfish glucagon, was shown to markedly stimulate the activity of the gland, increasing chloride secretion rates above baseline by approximately 16-fold (p’< 0.001), and it is proposed that this may be the primary signal for activation of the rectal gland post-feeding.
