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 growth hormone receptor (GHR) is potentially involved in prostate cancer through its role in stimulating insulin-like growth factor I production and its cellular effects on prostate epithelium. We have used a haplotype-based tagging approach within CAncer Prostate Sweden, a large retrospective case-control study of 2,863 cases and 1,737 controls to investigate if genetic variation in theGHR...

By use of RNase protection assays, hepatic growth hormone receptor (GHR) and insulin-like growth factor I (IGF-I) mRNA abundances were measured in sheep fetuses after experimental manipulation of fetal plasma thyroid hormone concentrations by fetal thyroidectomy (TX) and exogenous infusion of triiodothyronine (T(3)) and cortisol. TX abolished the normal prepartum rise in hepatic GHR abundance b...

the functional role of the exon 3 growth hormone receptor ( d3 ghr) polymorphism in human and its distributions in different populations is not clearly understood. the presence of full length growth hormone ( fl ghr) is the most  important in metabolic risk factors. the aim of this study was to define the frequency distribution of d3 ghr/full-length ghr in an iranian population. the presence of...

BACKGROUND To date, about sixty different mutations within GH receptor (GHR) gene have been described in patients with GH insensitivity syndrome (GHI). In this report, we described a novel nonsense mutation of GHR. METHODS The patient was evaluated at the age of 6 yr, for short stature associated to clinical phenotype of GHI. GH, IGF-1, and GHBP levels were determined. The PCR products from e...

The GH receptor 1A mRNA (GHR 1A mRNA) is one of the major GHR mRNA variants that differ in the 5'-untranslated region. The GHR 1A mRNA is unique because it is exclusively expressed in liver. The objective of the present study was to understand the mechanism for the liver-specific expression of the GHR 1A mRNA in the bovine. Twenty-six kilobases of 5'-flanking region of the bovine GHR gene was c...

OBJECTIVE Circulating GH-binding protein (GHBP) is produced by proteolytical cleavage of the extracellular part of the GH receptor (GHR) and is positively correlated to the amount of body fat. To test the hypothesis that adipose tissue may contribute to the production of circulating GHBP, we compared gene expression of two GHR isoforms in adipose tissue with serum GHBP concentrations in healthy...

In a population-based case-control study, we explored the associations between 42 polymorphisms in seven genes in this region and non-small cell lung cancer (NSCLC) risk among Caucasian (364 cases; 380 controls) and African American (95 cases; 103 controls) women. Two TERT region SNPs, rs2075786 and rs2853677, conferred an increased risk of developing NSCLC, especially among African American wo...

Growth hormone, acting through its receptor (GHR), plays an important role in carbohydrate metabolism and in promoting postnatal growth. GHR gene-deficient (GHR(-/-)) mice exhibit severe growth retardation and proportionate dwarfism. To assess the physiological relevance of growth hormone actions, GHR(-/-) mice were used to investigate their phenotype in glucose metabolism and pancreatic islet ...
