Project description:The response to growth hormone in humans is dependent on phenotypic, genetic and environmental factors. The present study in children with growth hormone deficiency (GHD) collected worldwide characterised gene-environment interactions on growth response to recombinant human growth hormone (r-hGH). Growth responses in children are linked to latitude, and we found that a correlation of latitude, summer daylight exposure (SDE) was a key environmental factor related to growth response to r-hGH. In turn growth response was determined by an interaction between both SDE and genes known to affect growth response to r-hGH. In addition analysis of associated networks of gene expression implicated a role for circadian clock pathways and specifically the developmental transcription factor NANOG. This work provides the first observation of gene-environment interactions in children treated with r-hGH.

Project description:MicroRNAs are widely expressed in the normal pubertal mammary gland and orchestrate mammary gland development by regulating cell proliferation, differentiation, apoptosis, and metabolism. Although human Growth hormone(hGH) plays fundamental roles in normal mammary gland development and elevated autocrine hGH levels have been documented to contribute to breast cancer, whether hGH should influence the expression pattern and the functional roles of miRNAs in this context remain unknown.This study explores the effects of autocrine hGH on microRNA expression in MCF7 cell.

Project description:Drugs of abuse including nicotine and alcohol elicit their effect by stimulating the mesocorticolimbic dopaminergic system. There is a high incidence of nicotine dependence in alcoholics. To date only limited data is available on the molecular mechanism underlying the action of alcohol and nicotine in the human brain. This study utilised gene expression screening to identify genes sensitive to chronic alcohol abuse within the ventral tegmental area of the human brain.

Project description:ABSTRACT: The human growth hormone (hGH) minigene is frequently used in transgenic mouse lines to ensure proper transgene expression. Here, we show that hGH is expressed in islets isolated from the commonly used Pdx1-CreLate mouse model. Locally secreted hGH activates prolactin receptors on M-NM-2 cells causing phosphorylation of STAT5, and induces a pregnancy-like change in gene expression, augmented pancreatic M-NM-2 cell mass and insulin content. In addition, islets of Pdx1-CreLate mice had lower GLUT2 expression, reduced glucose-induced insulin release and were protected against the M-NM-2 cell toxin streptozotocin. As the hGH minigene is commonly used in a great number of Cre-driver and other transgenic mouse models in diabetes research, the currently reported profound phenotypic changes may necessitate the re-evaluation of a large amount of previously published work. Data obtained for the Pdx1-creLate and control samples were compaired to investigate the effect of hGH on the mRNA profile of islets. The data obtained from the islets of pregnant mice was added to the analysis to confirm the pregnacy-like phenotype in the Pdx1-creLate islets. The data of the different days of pregnancy was already described in Schraenen et al. 2010 (PMID: 20886204 and PMID: 20938637). Islets were isolated from Pdx1-creLate, control and pregnant mice for RNA extraction and hybridization on Affymetrix microarrays. For every condition, at least 3 biological replicates were used.

Project description:The growth hormone plays a significant role in normal renal function and overactive growth hormone signaling has been implicated in proteinuria in diabetes. Earlier studies from our group have shown that the glomerular podocytes, which play an essential role in renal filtration, express the growth hormone receptor, suggesting the direct action of growth hormone on these cells. Nevertheless, the precise mechanism and the downstream pathways that are induced by the excess growth hormone in these podocytes leading to diabetic nephropathy are not clearly established. To compressively understand the growth hormone’s effect on podocytes at transcript level we performed RNA-Sequencing. Conditionally immortalized human podocytes were employed in this study.
