Studies with a panel of monoclonal antibodies (MAbs) reactive towards the presumptive rabbit liver growth-hormone (GH) receptor show that the rabbit serum GH-binding proteins share seven antigenic determinants (three at the hormone-binding site and four located elsewhere) with the liver cytosolic GH-binding proteins and the putative GH 'receptors' associated with the hepatocyte membrane. The ra...

Somatostatin (SRIF) analogs provide safe and effective therapy for acromegaly. In a proportion of patients, however, SRIF analogs may lead to discordant growth hormone (GH) and IGF-I suppression, which suggests a more complex mechanism than attributable to inhibition of GH release alone. To elucidate whether SRIF acts peripherally on the GH-IGF-I axis, we showed that rat hepatocytes express som...

GH appears to play an important metabolic role during late pregnancy and in lactation maintenance. In this study, pregnant (days 8, 15, and 20 of gestation) and postpartum (days 3 and 8 postpartum, including lactating and nonlactating dams) Wistar rats were used to investigate pituitary GH gene expression and hormone secretion, and the potential alterations of the major signals regulating GH se...

Catfish is one of the most important freshwater fish farming commodities in Indonesia. Higher catfish production can be achieved by cultivating transgenic carrying growth hormone (GH) gene African (Clarias gariepinus GH, CgGH). This research focuses on analysis presence CgGH G1, G2, and G3 mutiara broodstock, as an indication stable inheritance. was isolated using RNeasy mini kit RT-PCR. RT-PCR...

Human cytomegalovirus (HCMV) is a ubiquitous virus that is a major pathogen in newborns and immunocompromised or immunosuppressed patients. HCMV infects a wide variety of cell types using distinct entry pathways that involve different forms of the gH/gL glycoprotein: gH/gL/gO and gH/gL/UL128-131 as well as the viral fusion glycoprotein, gB. However, the minimal or core fusion machinery (suffici...

The production of peptide hormones by skeletal muscle tissue is a promising area of gene therapy. Skeletal muscle myogenesis can be induced in vitro, resulting in the fusion of mononucleate myoblasts to form multinucleate myotubes, and delivery vectors are first tested in vitro. C2C12 myoblasts transfected with pcDNA3-GH, which used the human cytomegalovirus (CMV) promoter, secreted immunoreact...

Growth hormone (GH) is a key determinant of postnatal growth and plays an important role in the control of metabolism and body composition. Surprisingly, deficiency in GH signaling delays aging and remarkably extends longevity in laboratory mice. In GH-deficient and GH-resistant animals, the "healthspan" is also extended with delays in cognitive decline and in the onset of age-related disease. ...

An increased dietary load of cholesterol (ch) and saturated fat increases serum low density lipoprotein ch (LDL-ch) levels. GH therapy in GH-deficient adults decreases serum LDL-ch levels. In the rat, GH is important for resistance to dietary cholesterol in terms of serum cholesterol levels. The aim of this study was to investigate the influence of GH on the effects of an increase in the intake...

Beef production is an important development area in animal breeding with meat quality being determined by both paratypic and genetic factors. In this regard evaluating genetic material for the presence of desirable allele combinations of genes associated with growth and development indicators, as well as meat qualities of animals have a certain scientific and practical significance. The aim of ...

Prior research indicates that growth hormone (GH) cell differentiation can be induced prematurely by treatment with glucocorticoids in vitro and in vivo. However, the nature of these responses has not been fully characterized. In this study, the time course of corticosterone induction of GH-secreting cells in cultures of chicken embryonic pituitary cells, responsiveness of differentiated somato...
