Growth hormone (GH)/GH receptor expression and GH-mediated effects during early bovine embryogenesis.
Pituitary growth hormone (GH) stimulates postnatal growth and metabolism. The role of GH and its receptor (GHR) during prenatal development, however, is still controversial. As shown by reverse transcription polymerase chain reaction (RT-PCR), bovine in vitro fertilization embryos synthesized the transcript of GHR from Day 2 of embryonic life onwards. Real time RT-PCR revealed that synthesis of...
متن کاملLiver and kidney growth hormone (GH) receptors are regulated differently in diabetic GH and GH antagonist transgenic mice.
Elevated GH levels are frequently seen in poorly controlled type I diabetics and have been implicated in diabetic complications. Studies of GH and GH antagonist (GHA) transgenic mice with streptozotocin (STZ)-induced diabetes have revealed that GH has a permissive effect for diabetic nephropathy, and that expression of a GHA gene protected mice against diabetic kidney lesions. To investigate wh...
متن کاملGrowth hormone (GH)-releasing peptide-6 requires endogenous hypothalamic GH-releasing hormone for maximal GH stimulation.
GH-releasing peptide-6 (GHRP-6) is a potent GH secretagogue that releases GH by uncertain mechanisms. To assess whether GHRH is required for GH release by GHRP-6 in humans, we used the specific antagonist to GHRH (N-Ac-Tyr1,D-Arg2)GHRH(1-29)NH2 (GHRH Ant). We have previously shown that GHRH-Ant (400 microg/kg) blocked the GH response to 0.33 and 3.3 microg/kg boluses of GHRH by 95% and 81%, res...
متن کاملGrowth hormone (GH) assays: influence of standard preparations, GH isoforms, assay characteristics, and GH-binding protein.
The impact of the adoption of the new biosynthetic growth hormone (GH) WHO International Reference Preparation (IRP 88/624), and the recommendation to report results in microgram/L instead of mU/L, is described. Conversion factors were determined by comparing both the linear and nonlinear relations of the GH values. The Pharmacia polyclonal IRMA (p-IRMA) and the DELFIA monoclonal time-resolved ...
متن کاملGrowth hormone (GH) provocation tests and the response to GH treatment in GH deficiency.
OBJECTIVE To identify factors, particularly the growth hormone (GH) provocation test result, affecting growth response to GH treatment in children with GH deficiency (GHD). SUBJECTS A total of 337 prepubertal GHD patients aged <10 years from the UK Pharmacia KIGS database (GH response to provocation test <20 mU/l). OUTCOME MEASURE Annual change in height standard deviation score (SDS) (revi...
