Expression of Somatotropin Receptor Messenger Ribonucleic Acid in Bovine Tissues

Journal of Dairy Science, 1998
The somatotropin receptor mRNA is controlled by at least two different gene promoters that generate two variants with different exon 1 sequences (1A and 1B). The location of 1A and 1B somatotropin receptor mRNA within cattle tissues and, hence, the tissue specificity of the 1A and 1B promoters are unknown.

Activity of 3β-hydroxysteroid dehydrogenase associated with progesterone production in bovine granulosa cells cultured under different concentrations of serum, insulin-like growth factor I, and gonadotropin [PDF]

, 2014
Three-β-hydroxysteroid dehydrogenase (3β-HSD) is the enzyme responsible for progesterone production. This study aimed to determine whether 3β-HSD activity can be shown to reflect progesterone production by granulosa cells cultured under different serum

Neither bovine somatotropin nor growth hormone-releasing factor alters expression of thyroid hormone receptors in liver and mammary tissues [PDF]

Journal of Dairy Science, 2011
Physiological effects of thyroid hormones are mediated primarily by binding of triiodothyronine to specific nuclear receptors. Organ-specific changes in production of triiodothyronine from its prohormone, thyroxine, have been hypothesized to target the action of thyroid hormones on the mammary gland and play a role in mediating or augmenting a ...

Somatostatin receptors differentially affect spontaneous epileptiform activity in mouse hippocampal slices [PDF]

, 2004
Somatostatin-14 (SRIF) reduces hippocampal epileptiform activity but the contribution of its specific receptors (sst1-5) is poorly understood. We have focused on sst1 and sst2 role in mediating SRIF modulation of epilepsy using hippocampal slices of wild

SOM230: a novel somatostatin peptidomimetic with broad somatotropin release inhibiting factor (SRIF) receptor binding and a unique antisecretory profile [PDF]

European Journal of Endocrinology, 2002
OBJECTIVE: The aim of the present study was to identify a small, metabolically stable somatotropin release inhibiting factor (SRIF) analog with a more universal binding profile similar to that of natural somatostatin, resulting in improved pharmacological properties and hence new therapeutic uses. DESIGN: A rational drug design approach was followed by

The impact of growth promoters on muscle growth and the potential consequences for meat quality [PDF]

, 2016
To meet the demands of increased global meat consumption, animal production systems will have to become more efficient, or at least maintain the current efficiency utilizing feed ingredients that are not also used for human consumption.

Immunofunctional assay of human growth hormone (hGH) in serum: A possible consensus for quantitative hGH measurement [PDF]

, 1996
Confirmation of the diagnosis of GH deficiency in adults and children involves provocative testing for human (h) GH. Different commercially available immunoassays yield largely discrepant results in the measurement of GH levels in human serum.

Involvement of the hypothalamic-pituitary-thyroid axis and its interaction with the hypothalamic-pituitary-adrenal axis in the ontogeny of avian thermoregulation: a review [PDF]

, 2008
The emergence of thermoregulation in avian species is a complex matter in which neural as well as hormonal processes are involved. In a previous paper, the neural aspects of primary avian thermoregulation were discussed.

Covalent cross-linking of the bovine somatotropin dimer. Effects on growth-promoting, receptor-binding and immunological activities and preliminary characterization of the self-association [PDF]

Biochemical Journal, 1983
Bovine somatotropin, at pH 8.5 in 0.02 M-Bicine [NN-bis-(2-hydroxyethyl)glycine]/0.09M-NaCl, showed by frontal analysis the characteristics of a rapid monomer-dimer equilibrium whose dissociation constant was estimated to be 6.6×10(-6)M. Reaction of the hormone with dimethyl suberimidate lead to covalent cross-linking of the dimeric species.
