PURPOSE We have demonstrated that a 2'-O-methoxyethyl modified antisense oligonucleotide against the mouse growth hormone (GH) receptor (GHr) reduces GH binding and serum insulin-like growth factor-1 in normal mice. We tested whether this systemically delivered antisense oligonucleotide could inhibit neovascularization in mice with oxygen induced retinopathy (OIR). METHODS OIR was induced in ...
CONTEXT The GH receptor (GHR) pseudoexon 6Psi defect is a frequent cause of GH insensitivity (GHI) resulting from a non-functioning GH receptor (GHR). It results in a broad range of phenotypes and may also be present in patients diagnosed as idiopathic short stature. OBJECTIVE Our objective was to correct aberrant GHR splicing and inclusion of 6Psi using exon-skipping antisense oligonucleotid...
3-Methylcholanthrene (MC) is a readily metabolized aryl hydrocarbon receptor (AHR) agonist. MC disrupts expression of mouse hepatic growth hormone (GH) signaling components and suppresses cytochrome P450 2D9 (Cyp2d9), a male-specific gene controlled by pulsatile GH via signal transducer and activator of transcription 5b (STAT5b). To determine if these effects of MC depend on hepatic microsomal ...
Porcine and bovine GH receptor (GHR) cDNAs were stably expressed in mouse L cells, which normally do not possess detectable levels of mouse GHR. Expression of the GHR cDNAs resulted in specific binding of 125I-labeled GH by these cell lines. To study GHR-related signaling events in these cells, protein tyrosine phosphorylation was examined. In GH-treated cells, a tyrosine-phosphorylated protein...
The order Rodentia contains half of all extant mammal species, and from an evolutionary standpoint, there are persistent controversies surrounding the monophyly of the order, divergence dates for major lineages, and relationships among families. Exons of growth hormone receptor (GHR) and breast cancer susceptibility (BRCA1) genes were sequenced for a wide diversity of rodents and other mammals ...
A signi cant genetic component is involved in the development of the craniofacial form. Recently, the growth hormone receptor gene (GHR) variants rs6180 and rs6184 were associated with variations in mandibular form. To con rm these ndings we evaluated the relationship between these GHR variants and mandibular form in a cohort of Egyptian individuals with a normal skull form. The patients consis...
The growth hormone receptor (GHR) is a critical regulator of postnatal growth and metabolism. However, the GHR signaling domains and pathways that regulate these processes in vivo are not defined. We report the first knock-in mouse models with deletions of specific domains of the receptor that are required for its in vivo actions. Mice expressing truncations at residue m569 (plus Y539/545-F) an...
Expression of growth hormone (GH) and GH receptor (GHR) genes in the bursa of Fabricius of chickens suggests that it is an autocrine/paracrine site of GH production and action. The cellular localization of GH and GH mRNA within the bursa was the focus of this study. GH mRNA was expressed mainly in the cortex, comprised of lymphocyte progenitor cells, but was lacking in the medulla where lymphoc...
Sorghum is a principal cereal food in a number of parts of the world and is critical in folk medicine in Asia and Africa. However, its effects on bone are unknown. Growth hormone (GH) is a regulator of bone growth and bone metabolism. GH activates several signaling pathways, including the Janus kinase (Jak)/signal transducer and activator of transcription (STAT) pathways, thereby regulating exp...
Growth and development in fish are regulated to a major extent by growth-related factors, such as liver-derived insulin-like growth factor (IGF) -1 in response to pituitary-secreted growth hormone (GH) binding to the GH receptor (GHR). Here, we report on the changes in the expressions of gh, ghr, and igf1 genes and the circulating levels of GH and IGF-1 proteins in juvenile coho salmon (Oncorhy...
