Y Gallais, N Szely, F-X Legrand, A Leroy, M Pallardy, I Turbica
Patients treated with therapeutic biological products (BP) frequently develop anti-drug antibodies (ADA) with potential neutralizing capacities leading to loss of clinical response, or serious side effects. BP aggregates have been suggested to promote immunogenicity thus enhancing ADA production. Dendritic cells (DC) are key effectors in T-cell and B-cell fates and the subsequent generation of immunogenicity. The objective of this work was to determine if BP aggregates can participate to DC maturation and T-cell activation...

Transgenic mouse models have been fundamental in the discovery of factors that regulate β-cell development, mass, and function. Several groups have recently shown that some of these models display previously uncharacterized phenotypes due to the transgenic system itself. These include impaired islet function and increased β-cell mass due to the presence of a human growth hormone (hGH) minigene as well as impaired β-cell proliferation in response to tamoxifen (TM) administration. We aimed to determine how these systems impact β-cell mass and proliferation during high fat diet (HFD)...

Isotopically labeled proteins have been used as internal standards for mass spectrometry (MS)-based absolute protein quantification. Although this approach can provide highly accurate analyses of proteins of interest within a complex mixture, one of the major limitations of this method is the difficulty in preparing uniformly labeled standards. Human growth hormone (hGH) is one of the most important hormones that circulate throughout the body, and its measurement is primarily of interest in the diagnosis and treatment of growth disorders...

A newly developed hybrid Fc (hyFc) is a non-immunogenic and non-cytolytic Fc with intact Ig structure derived from human IgD and IgG4. It is fused with the human growth hormone (GXD-9) and was evaluated by various biophysical techniques. Two thermal transitions were evident by DSC, reflecting the unfolding of IgG4 and the conjugated protein. The highest Tm of the initial GXD-9 was 68.17°C and the Tm of the two domains were around 66°C and 70°C. Although Tm increased with decreasing concentration, which reflects increasing conformational stability, aggregation issues were still observed by DLS...

BACKGROUND: Although it is being increasingly applied, blood collection for drug testing in sport presents some logistic issues that complicate full applicability on a large scale. The use of dried blood spots (DBS) could benefit compliant blood testing considerably owing to its simplicity, minimal invasiveness, analyte stability, and reduced costs. The aim of this study was to evaluate the applicability of DBS to the methodology approved by the World Anti-Doping Agency (WADA) for detection of doping by recombinant human growth hormone (rhGH) in serum...

The expression of Wingless and Int-related protein (Wnt) ligands is aberrantly high in human breast cancer. We report here that WNT4 is significantly upregulated at the mRNA and protein level in mammary carcinoma cells expressing autocrine human growth hormone (hGH). Depletion of WNT4 using small interfering (si) RNA markedly decreased the rate of human breast cancer cell proliferation induced by autocrine hGH. Forced expression of WNT4 in the nonmalignant human mammary epithelial cell line MCF-12A stimulated cell proliferation in low and normal serum conditions, enhanced cell survival and promoted anchorage-independent growth and colony formation in soft agar...

Human Growth Hormone (hGH, somatotropin) is one of the relevant forbidden substances to be detected in sport drug testing. Since the appearance of recombinant hGH (rhGH) in the 80's, its expansion and availability through the black market have increased, so the detection of its abuse continues to be a challenge at present. New techniques or biomarkers that are robust, reliable, sensitive and allowing a large detection time window are welcome. rhGH produces an increase of insulin-like growth factor 1 (IGF-1)...

Cinnamoyl alginate, cinnamoyl Pluronic F127 and cinnamoyl poly(ethylene glycol) were self-assembled into nanogel in aqueous phase. The size of nanogel was 100nm-200nm on TEM photos. When 1ml of human growth hormone (hGH) solution (5mg/ml, pH3.0) was mixed with 4ml of the nanogel suspension (37.5mg/ml, pH3.0), 100% of hGH was loaded in the nanogels (corresponding to specific loading of 3.33% (w hGH/w nanogel)). In the in vivo pharmacokinetics study, the substantial blood level of hGH was maintained during the entire experiment period (two weeks) after one-time injection of hGH-loaded nanogel at 0...

Human growth hormone (hGH) plays an important role during human development and is also an approved therapeutic for the treatment of several diseases. However, one major drawback of hGH is its short circulating half-life requiring frequent administration, which is inconvenient and painful for the patients. Recent publications indicate that circularization greatly increases the stability of proteins due to their protection from exoproteolytic attack and a higher thermal stability of the circular form. Using sortase A, a transpeptidase isolated from Staphylococcus aureus, we developed a single step solid-phase circularization and purification procedure resulting in a circular version of hGH with improved properties...

The death rates of hepatocellular carcinoma (HCC) are extremely high due to the paucity of therapeutic options. Animal models and anecdotal clinical evidence indicate a potential role of hGH and hPRL in HCC. However, the prognostic relevance and the functional role of tumor expression of these hormones in human HCC are not defined. Herein, we analyzed the mRNA and protein expression of hGH and hPRL in histopathological samples of non-neoplastic liver and HCC by in situ hybridization, PCR and immunohistochemistry techniques...

According to phylogenetic theory of general pathology, the function of low density lipoproteins (LDL) and hydrolysis of triglycerides (TG) in them under the effect of hepatic glycerol hydrolase apoC-III (HGH) developed at much earlier stages of phylogenesis than functioning of insulin-dependent phylogenetically late very low density lipoproteins (VLDL). For millions ofyears, lipolysis and HGH+apoC-III have activated transfer of polyenic fatty acids (FA) in the form of cholesteryl polyesters (CLE) from high density lipoproteins (HDL) to linoleic and linolenic LDL under the effect of cholesteryl ester transfer protein...

The purpose of this study was to develop and characterize a sodium hyaluronate microparticle-based sustained release formulation of recombinant human growth hormone (SR-rhGH) prepared by spray-drying. Compared to freeze-drying, spray-dried SR-rhGH showed not only prolonged release profiles but also better particle property and injectability. The results of size-exclusion high-performance liquid chromatography showed that no aggregate was detected, and dimer was just about 2% and also did not increase with increase of inlet temperature up to 150 °C...

OBJECTIVES: The catabolic phase following burn injuries increases caloric imbalance and results in substantial weight loss because of hypermetabolism; energy expenditures as high as twice the normal limit have been documented during the first 3 weeks. Furthermore, the wound size and healing duration seem to be related to the length of stay in the intensive care unit, which results in the loss of muscle mass, the so-called sarcopenia; weakness; and physical frailty. Possible therapeutic strategies include exercises, use of anabolic steroids, or replacement with human growth hormone (hGH)...
