BACKGROUND: Growth retardation and its impact on adult height is considered to be one of the most common complications in patients with chronic kidney disease (CKD). Treatment with recombinant human growth hormone (rhGH) has been effective in improving growth in kidney transplantation (KTx) patients, but little data are available on adult height in patients who began rhGh treatment in late puberty. METHODS: Near-adult height was evaluated in 13 KTx patients treated with rhGH [growth hormone group (GHGr); dose 9...

PURPOSE: Growth retardation is a common complication of chronic kidney disease (CKD) in children. Treatment with recombinant human growth hormone (rhGH) has been used to help short children with CKD to attain a height more in keeping with their age group, but the scientific evidence regarding the effect of rhGH on final height is scarce. METHODS: Final heights of children with CKD receiving rhGH treatment (cases) were compared with final heights of a matched cohort of children with CKD that did not receive rhGH therapy (controls)...

Selecting rootstocks for high nitrogen acquisition ability may allow decreased N fertilizer application without reducing tomato yields, minimizing environmental nitrate pollution. A commercial hybrid tomato variety was grafted on a genotyped population of 130 recombinant inbred lines (RILs) derived from Solanum pimpinellifolium, and compared with self- and non-grafted controls under contrasting nitrate availabilities (13.8 vs 1.0mM) in the nutrient solution. Grafting itself altered xylem sap composition under N-sufficient conditions, particularly Na(+) (8...

Objective Growth hormone (GH) deficiency (GHD) is commonly treated with recombinant human GH (rhGH). Individual response to rhGH therapy varies widely and there is evidence that variations in growth-related genes, e. g. the GH receptor (GHR) gene, may impact treatment response. We aimed to identify genetic polymorphisms which could serve as predictive markers of response to rhGH therapy. Methods We conducted a genetic analysis of single nucleotide polymorphisms (SNPs) and the GHR exon 3 deletion in 101 paediatric GHD patients receiving rhGH...

BACKGROUND/AIMS: Kabuki syndrome (KS) is a rare genetic malformation syndrome, resulting in characteristic features such as short stature. We investigate whether growth hormone (GH) treatment increases linear height and influences body proportions in KS children. METHODS: In this prospective study, 18 genetically confirmed prepubertal KS children (9 females and 9 males) aged from 3.8 to 10.1 years (mean 6.8 ± 2.1 years) were treated with recombinant human GH (rhGH) for 1 year...

Recombinant bovine somatotropin (rbST), a synthetic growth hormone, is used to stimulate growth and enhance milk production in dairy cows. Both its use and the sale of dairy products from treated animals are prohibited in the European Union, Japan, Australia, New Zealand, and Canada, but authorised in several countries (e.g. the USA, Brazil). Screening methods involve detecting anti-rbST antibodies (biomarkers) in treated cows. Confirmatory methods are required to prove rbST abuse. The major challenges in determining rbST are its potentially low levels, its high similarity to native bST, and matrix interferences...

BACKGROUND: It is thought that growth hormone (GH) therapy success depends on the patient's adherence to their treatment regimen, but an optimal approach to improve adherence has not yet been established. METHODS: To evaluate the effect of patient choice of a GH device on adherence to GH therapy, we carried out a retrospective longitudinal study of 46 GH deficient patients (24 boys, mean age of commencing GH therapy: 7.70±3.12 years) treated with recombinant GH therapy for 3 years, either with or without patient choice (n=28, 18, respectively)...

Triple-negative breast cancer (TNBC), lacking the steroid hormone receptors ER and PR and the oncoprotein HER2, is characterized by its aggressive pattern and insensitivity to endocrine and HER2-directed therapy. Human kallikrein-related peptidases KLK1-15 provide a rich source of serine protease-type biomarkers associated with tumor growth and cancer progression for a variety of malignant diseases. In this study, recombinant KLK4 protein was generated and affinity-purified KLK4-directed polyclonal antibody pAb587 established to allow localization of KLK4 protein expression in tumor cell lines and archived formalin-fixed, paraffin-embedded TNBC tumor tissue specimens...

It has been 42 years since a protein, now known as interferon tau (IFNT), was discovered in ovine conceptus-conditioned culture medium. In 1975, purification and testing of native IFNT revealed its unique antiluteolyic activity to prevent regression of corpora lutea on ovaries of nonpregnant ewes. Antiviral, antiproliferative and immunomodulatory properties of native and recombinant IFNT were also demonstrated. In addition, progesterone and IFNT were found to act cooperatively to silence expression of classical interferon stimulated genes in a cell-specific manner in ovine uterine luminal and superficial glandular epithelia...

BACKGROUND: Recombinant human growth hormone (rhGH) treatment in children is usually prescribed using actual body weight. This may result in inappropriately high doses in obese children. METHODS: Retrospective audit of all paediatric patients treated with rhGH 2010-14 at a tertiary paediatric hospital in the UK. Change in height SDS and IGF-I SDS during the first year of treatment was stratified by initial BMI SDS in a mixed cohort, and a subgroup of GH deficient (GHD) patients...

If cultured in appropriate conditions, such as supplementing culture media with costly cytokines and growth factors, hematopoietic stem/progenitor cells (HSPCs) from different origins have shown to be an adequate source of erythroid cells. This requirement turns erythroid cells production into a complicated process to be scaled-up for future applications. The aim of our work was to genetically modify HSPCs with human erythropoietin (hEPO) sequence by lentiviral transgenesis in order for cells to secrete the hormone into the culture medium...

BACKGROUND: Fibroblast growth factor 21 (FGF21) is an endocrine-acting hormone that has the potential to treat diabetic nephropathy. However, development of FGF21 into a therapeutic has been hindered due to its low intrinsic bio-stability. In our previous study, we have developed a recombinant human FGF21 (rhFGF21) variant by site-directed mutagenesis and solid-phase PEGylation, which retained its biological function. The aim of this study is to elucidate whether the therapeutic effect of PEGylated rhFGF21 (PEG-rhFGF21) on diabetic nephropathy in DIO (diet induced obesity) mice is more significant than rhFGF21 in vivo...

Insulin-like growth factor (IGF)-I is a growth promoting hormone that exerts its actions through endocrine, paracrine and autocrine modes. Local IGF-I is essential for normal growth, whereas circulating IGF-I plays a crucial role in regulating the production and secretion of growth hormone (GH) by the pituitary gland. These actions of IGF-I are modulated by six insulin-like growth factor binding proteins (IGFBPs). In teleosts, two subtypes of each IGFBP are present due to an extra round of whole-genome duplication...

The growth hormone (GH)/insulin-like growth factors (IGFs) endocrine axis is the main growth-regulator system in vertebrates. Some authors have demonstrated the positive effects on growth of a sustained-release formulation of a recombinant bovine GH (rBGH) in different fish species. The aim of this work was to characterize the effects of a single injection of rBGH in fingerlings of gilthead sea bream on growth, GH-IGF axis, and both myogenic and osteogenic processes. Thus, body weight and specific growth rate were significantly increased in rBGH-treated fish respect to control fish at 6weeks post-injection, whereas the hepatosomatic index was decreased and the condition factor and mesenteric fat index were unchanged, altogether indicating enhanced somatic growth...
