The first successful attempts to transfer foreign DNA into mice (Gordone, et al, 1980) were rapidly followed by a number of reports demonstrating that foreign DNA, or transgenes, can be permanently incorporated into an animal’s genome (Costantini and Lacy, 1981; E. Wagner, et al, 1981; T. Wagner, et al., 1981). Once incorporated, transgenes are stable and can be transmitted to an animal’s proge...

this study investigated the effects of five levels of galanin on plasma concentrations of growth hormone , triiodothyronine, thyroxine and milk fat in dairy goat breed was sannan .15 breeds of dairy goats sannan all about the same age and weight were selected for this study and were randomly divided into five treatments ( three replicates per treatment ). levels of the hormone injection of gala...

This review addresses the effects of growth hormone on diurnal insulin sensitivity in normal, patients with type 2 diabetes mellitus (T2DM) and animal models described in our previous studies. Results confirmed the presence of diurnal insulin sensitivity, or greater insulin sensitivity in the morning, in normal subjects. The exact cause of this circadian rhythm in plasma glucose levels in healt...

The aim of this study was to investigate the potential association between growth hormone GH/AluI and growth hormone receptor GHR/AluI polymorphisms with milk yield and reproductive performances in Holstein dairy cows in Iran. Blood samples of 150 Holstein cows were collected and their genomic DNA was extracted using Gene-Fanavaran DNA extracting kit. Fragments of the 428 bp of exon 5 growth ho...

The effects of breed and of recombinant bovine somatotropin (rbST) treatment on growth hormone gene expression were studied in young bulls. The experiment was completely randomized in a [2 x 2]-factorial arrangement, using two levels of rbST (0 or 250 mg/animal/14 days), and two breed groups (Nelore and Simmental x Nelore crossbred). A cDNA encoding Bos indicus growth hormone was cloned and seq...
