2022 journal article

Evidence for a leptin-insulin axis in a fish, the tilapia (Oreochromis mossambicus)

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

By: 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)

2021 journal article

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

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)

TL;DR: Evidence across the vertebrate taxa on the diversity of nongenomic actions of glucocorticoids and the membrane-associated cellular mechanisms that may underlie rapid glucoc Corticoid responses to include potential binding sites characterized to date is assimilated. (via Semantic Scholar)

2019 journal article

Warmer waters masculinize wild populations of a fish with temperature-dependent sex determination

Scientific Reports, 9(1).

By: J. Honeycutt n, C. Deck n, S. Miller n, M. Severance n, E. Atkins n, J. Luckenbach*, J. Buckel n, H. Daniels n ...

MeSH headings : Animals; Animals, Wild / physiology; Ecosystem; Female; Fishes / anatomy & histology; Fishes / physiology; Gonads / metabolism; Hot Temperature; Male; North Carolina; RNA, Messenger / genetics; RNA, Messenger / metabolism; Sex Determination Processes; Sex Ratio; Water
TL;DR: Rearing flounder in the laboratory under temperature regimes mimicking those of natural habitats recapitulated sex ratio differences observed across the wild populations, providing strong evidence that temperature is a key factor influencing sex ratios in nursery habitats.

2017 journal article

Control of leptin by metabolic state and its regulatory interactions with pituitary growth hormone and hepatic growth hormone receptors and insulin like growth factors in the tilapia (Oreochromis mossambicus)

GENERAL AND COMPARATIVE ENDOCRINOLOGY, 240, 227–237.

By: J. Douros n, D. Baltzegar n, J. Mankiewicz n, J. Taylor n, Y. Yamaguchi*, D. Lerner*, A. Seale *, E. Grau*, J. Breves *, R. Borski n

author keywords: Leptin; Growth hormone; Insulin-like growth factors; Growth hormone receptor; Teleost fishes; Metabolic stress
MeSH headings : Animals; Body Weight / drug effects; Fasting; Feeding Behavior / drug effects; Gene Expression Regulation / drug effects; Growth Hormone / metabolism; Hepatocytes / drug effects; Hepatocytes / metabolism; Hypophysectomy; Insulin-Like Growth Factor I / metabolism; Insulin-Like Growth Factor II / metabolism; Leptin / metabolism; Liver / metabolism; Male; Pituitary Gland / drug effects; Pituitary Gland / metabolism; RNA, Messenger / genetics; Receptors, Somatotropin / genetics; Receptors, Somatotropin / metabolism; Tilapia / metabolism
TL;DR: Findings indicate LepA gene expression and secretion increases with fasting, consistent with the hormones function in promoting energy expenditure during catabolic stress, and suggests for the first time in teleosts that GH may exert important regulatory effects on hepatic LepA production.

Epigenetic control of intestinal barrier function and inflammation in zebrafish

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 112(9), 2770–2775.

By: L. Marjoram, A. Alvers, M. Deerhake *, J. Bagwell, J. Mankiewicz n, J. Cocchiaro, R. Beerman, J. Willer * ...

author keywords: inflammation; Uhrf1; DNA methylation; tumor necrosis factor; zebrafish
MeSH headings : Animals; DNA Methylation; Epigenesis, Genetic / physiology; Epithelial Cells / metabolism; Epithelial Cells / pathology; Inflammation / genetics; Inflammation / mortality; Inflammation / pathology; Inflammatory Bowel Diseases / genetics; Inflammatory Bowel Diseases / metabolism; Inflammatory Bowel Diseases / pathology; Intestinal Mucosa / embryology; Intestinal Mucosa / pathology; Trans-Activators / genetics; Trans-Activators / metabolism; Tumor Necrosis Factor-alpha / immunology; Tumor Necrosis Factor-alpha / metabolism; Zebrafish / embryology; Zebrafish / genetics; Zebrafish Proteins / genetics; Zebrafish Proteins / metabolism
TL;DR: This work shows that loss of epigenetic regulation results in the induction of TNF in the intestinal epithelium, leading to a loss of intestinal barrier function and inflammation, and suggests that mutations in genes controlling epigenetic regulators can lead to IBD onset.
