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 the GH...

CISISOCS (cytokine-inducible SH2 protein/suppressor of cytokine signaling) are a family of proteins that are thought to act as negative regulators of signaling by erythropoetin, interleukin-6 and other cytokines whose receptors are related to the growth hormone receptor (GHR), and like growth hormone (GH), signal through the JAWSTAT pathway. We examined the possibility that CIS/SOCS proteins ma...

OBJECTIVES This paper strives to develop a pragmatic view of the scope of practice and core characteristics of global health research (GHR) by examining the activities of 14 Canadian-funded global health teams that were in the process of implementing research programs. METHODS Information was collected by a reflective exploration of team proposals and progress reports, a content analysis of t...

OBJECTIVES The objectives of this study were to assess the reactions of adult patients and parents of children with metabolic conditions to receipt of an "information prescription" (IP) to visit Genetics Home Reference (GHR), a National Institutes of Health/National Library of Medicine online resource, and evaluate the perceived utility of information found on the site. METHODS Patients seen ...

The expression of the growth hormone receptor (GHR) gene was investigated in semitendinosus muscle during bovine foetal development in both normal and double-muscled Charolais foetuses which differ with respect to muscle development. Northern-blot analysis of foetal muscle RNA preparations with a GHR cDNA probe identified the 4.5 kb GHR mRNA as early as 130 days post-conception. In double-muscl...

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...

BACKGROUND This study investigated the association between the frequency of growth hormone receptor (GHR) exon 3 polymorphism (exon 3 deletion; d3-GHR) and metabolic factors in patients with acromegaly in Korea. METHODS DNA was extracted from the peripheral blood of 30 unrelated patients with acromegaly. GHR genotypes were evaluated by polymerase chain reaction and correlated with demographic...

Growth hormone (GH), acting through its receptor (GHR), is essential for somatic growth and development and maintaining metabolic homeostasis. GHR gene deficient (GHR) mice exhibit drastically diminished IGF-I levels, proportional growth retardation, elevated insulin sensitivity and reduced islet β-cell mass. Unlike the liver which is mostly unaffected by changes in the IGF-I level, skeletal mu...

In the present study, primary mouse hepatocytes from 8- to 10-week-old virgin female Swiss-Webster mice were perfused with collagenase (100 U/ml) using the two-step method. Isolated hepatocytes were plated in a rat tail type I collagen sandwich configuration to examine the regulation of GH receptor (GHR) and GH-binding protein (GHBP) expression by GH and 17beta-estradiol (E2). After 48 h of ini...
