Context Autosomal-recessive mutations in the growth hormone receptor (GHR) are the most common causes for primary growth hormone insensitivity (GHI) syndrome with classical GHI phenotypically characterized by severe short stature and marked insulin-like growth factor (IGF)-I deficiency. We report three families with dominant-negative heterozygous mutations in the intracellular domain of the GHR...
GH (growth hormone) binding to the GHR (GH receptor) triggers essential signalling pathways that promote growth and metabolic regulation. The sensitivity of the cells to GH is mainly controlled by the endocytosis of the receptor via βTrCP (β-transducin repeat-containing protein). In the present study, we show that βTrCP interacts directly via its WD40 domain with the UbE (ubiquitin-dependent en...
BACKGROUND MicroRNAs have important roles in many biological processes. However, the role of miR-139 in healthy mammary gland remains unclear. The objective of this study was to investigate the effects of miR-139 on lactation in dairy cows. RESULTS Here, we found that miR-139 was down-regulated in mid-lactation dairy cow mammary tissues compared with mid-pregnancy tissues. Then, we prioritize...
Growth hormone (GH) is essential for quality of life in both children and adults, but it is also believed to enhance the growth of various neoplasms. However, the role of GH in the brain, particularly in brain tumors, has yet to be established. To clarify these problems from the perspective of receptor expression, we examined GH receptor (GHR) expression in brain tumors using immunohistochemist...
Two truncated isoforms of growth hormone (GH) receptor (GHR) were identified in mice and in humans. The proteins encoded by these isoforms lack most of the intracellular domain of the GHR and inhibit GH action in a dominant negative fashion. We have quantified the mRNAs encoding the GHR isoforms in mouse tissues by use of real-time RT-PCR and examined the effect of GH excess or deficiency on re...
The inhibition of growth hormone (GH) signaling by five members of the GH-inducible suppressor of cytokine signaling (SOCS/CIS) family was investigated in transfected COS cells. Complete inhibition of GH activation of the signal transducer STAT5b and STAT5b-dependent transcriptional activity was observed upon expression of SOCS-1 or SOCS-3, while partial inhibition (CIS, SOCS-2) or no inhibitio...
BACKGROUND Recognising radical shifts in the global health research (GHR) environment, participants in a 2013 deliberative dialogue called for careful consideration of equity-centred principles that should inform Canadian funding polices. This study examined the existing funding structures and policies of Canadian and international funders to inform the future design of a responsive GHR funding...
Acquired GH resistance together with reduced skeletal muscle mass are found in patients with increased protein catabolism due, for example, to sepsis, trauma, or major surgery. Both administration of glutamine-containing parenteral nutrition and GH treatment have been found to diminish this catabolism. The effects of GH are mediated in part by insulin-like growth factor I (IGF-I) that is produc...
Sepsis, a life-threatening complication of infections and the most common cause of death in intensive care units, is characterized by a hyperactive and out-of-balance network of endogenous proinflammatory cytokines. None of the current therapies are entirely effective, illustrating the need for novel therapeutic approaches. Ghrelin (GHR) is an orexigenic peptide that has emerged as a potential ...
