Plasma and pituitary GH concentrations and liver GH receptor (GHR), IGF-I and IGF-binding protein-3 (IGFBP-3) mRNA expression were determined in brushtail possum (Trichosurus vulpecula) pouch young aged 12-150 days post-partum and in adults. Mean plasma GH concentrations were highest, measuring around 150 ng/ml, from 12 to 100 days post-partum, and thereafter declined so that by 150 days post-p...

Human facial morphology varies considerably among individuals and can be influenced by gene polymorphisms. We explored the effects of single nucleotide polymorphisms (SNPs) on facial features in the Uygur youth population of the Kashi area in Xinjiang, China. Saliva samples were collected from 578 volunteers, and 10 SNPs previously associated with variations in facial physiognomy were genotyped...

Quantitative trait loci (QTL) studies have indicated growth hormone receptor (GHR) as a candidate gene affecting cattle milk yield and composition. In order to characterize genetic variation at GHR in cattle, we studied European and East African breeds with different histories of selection, and Bos grunniens, Ovis aries, Sus scrofa, Bison bison and Rangifer tarandus as references. We sequenced ...

Global disruption of the GH receptor in mice (GHR-/-) produces a large and reproducible extension in lifespan. Since lack of GH action in muscle resulting in improved glucose homeostasis is potentially a mechanism by which GHR-/- mice are long-lived, and since no information on muscle-specific GHR disruption in females is available, we generated and characterized a line of muscle-specific GHR d...

The present study was aimed to validate the previously found SNPs using NGS-based amplicon sequencing and investigate of their association with egg production weight by PCR-RFLP in Anand Synthetic White Leghorn (ASWLH) Bantamised (ABWLH) chicken. A total 500 blood samples were collected including, 227 ASWLH 273 ABWLH maintained at Poultry Research Station, Agricultural University, Anand, Gujara...

BACKGROUND Ghrelin plays important roles in glucose metabolism, appetite, and body weight regulation, and recent evidence suggests ghrelin prevents excessive anxiety under conditions of chronic stress. METHODS We used ghrelin knockout (ghr-/-) mice to examine the role of endogenous ghrelin in anxious behavior and hypothalamic-pituitary-adrenal axis (HPA) responses to acute stress. RESULTS G...

OBJECTIVE The exon 3-deleted/full-length (d3/fl) growth hormone receptor (d3/fl-GHR) polymorphism has been associated with responsiveness to GH therapy in some children and also with adult height variation in the general population. We aimed to evaluate the distribution of d3/fl-GHR polymorphism in a Turkish population. METHODS The study included 477 (54 females/423 males) healthy adults with...

The activity of the somatotropic axis was analysed in juvenile rainbow trout (Oncorhynchus mykiss) fed either a fishmeal-based diet (FM) or graded levels of plant proteins to replace 50% (PP50 diet), 75% (PP75 diet) or 100% (PP100 diet) of the fishmeal protein. For this purpose, partial cloning and sequencing of the gene encoding rainbow trout growth hormone receptor (GHR) was first accomplishe...

Large cell neuroendocrine carcinoma (LCNEC) is an aggressive neoplasm with a low frequency of occurrence in the digestive tract. We present a series of eight patients diagnosed with LCNEC of the colon and rectum. Grossly, tumors were presented as endophytic/ulcerative, annular and polypoid masses, with a gray-white color and necrosis in most cases. Histologically, they were high-grade tumors co...
