Factors Affecting Multiple Paternity: Insights From the Eastern Quoll (Dasyurus viverrinus)

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Eastern quolls (Dasyurus viverrinus) exhibit multiple paternity in approximately half of all litters. Reproductive success is correlated with heavier weight, youth, and being black rather than fawn colour morph. A cross‐species analysis indicates that high rates of multiple paternity within the Dasyuridae area correlated with shorter lifespan and ...

Development of a genetically encoded melanocortin sensor for high sensitivity in vivo imaging

Molecular Metabolism
Objective: The central melanocortin system, composed of peptides derived from pro-opiomelanocortin (POMC) such as the melanocyte-stimulating hormones (α-, β-, γ-MSH) and melanocortin 4 receptors (MC4R), along with the agouti-related protein (AgRP), plays

Perceived Stress, Hair Cortisol and Hair Cortisone in Relation to Appetite-Regulating Hormones in Patients with Obesity

Obesity Facts
Introduction: Stress predicts unhealthy eating, obesity, and metabolic deterioration, likely mediated by altered levels of appetite- and metabolism-regulating hormones.

The role of insulin receptor substrate 2 in hypothalamic and β cell function [PDF]

, 2005
Insulin receptor substrate 2 (Irs2) plays complex roles in energy homeostasis. We generated mice lacking Irs2 in β cells and a population of hypothalamic neurons (RIPCreIrs2KO), in all neurons (NesCreIrs2KO), and in proopiomelanocortin neurons ...

Characterization of the rabbit agouti signaling protein (ASIP) gene: transcripts and phylogenetic analyses and identification of the causative mutation of the nonagouti black coat colour

, 2010
The agouti locus encodes the agouti signalling protein (ASIP) which is involved in determining the switch from eumelanin to pheomelanin synthesis in melanocytes. In the domestic rabbit (Oryctolagus cuniculus) early studies indicated three alleles at this

Role of Insulin-like Growth Factor-1 in the Central Regulation of Feeding Behavior in Chicks

The Journal of Poultry Science, 2019
Insulin-like growth factor-1 (IGF-1) is a key regulator of muscle development and metabolism in chickens. Recently, we have demonstrated that intracerebroventricular administration of IGF-1 significantly decreased food intake in broiler chicks.

Alteration of sheep coat color pattern by disruption of ASIP gene via CRISPR Cas9

Scientific Reports, 2017
Coat color is an important characteristic and economic trait in domestic sheep. Aiming at alteration of Chinese merino sheep coat color by genome manipulation, we disrupted sheep agouti signaling protein gene by CRISPR/Cas9.

Mc1r, Agouti signaling protein (ASIP) and CBD103 are involved in brindle coat colour of Boxer and Great Dane dogs

, 2010
In most mammals, variations in skin and hair colour (brown/black eumelanin and the red/yellow phaeomelanin) are mainly achieved by the interaction between two genes: Agouti signaling protein (ASIP) and melanocortin 1 receptor (Mc1r) encoding a ligand ...

RING finger protein 17 (Rnf17) of Myc/Max/Mxd network: expression and function during mouse reproduction and development

, 2013
The preimplantation mammalian embryo is sensitive to the environment in which they develop and grow, either in vivo or in vitro. Disturbance to embryo environmental conditions can affect embryo growth.
