Human parathyroid hormone (hPTH) is a peptide hormone consisting of 84 amino acids (hPTH(1-84)). Employing the promoter and signal sequence of Staphylococcus aureus-protein A we have expressed hPTH in Escherichia coli. The expressed proteins are excreted to the growth medium, allowing for rapid and easy purification of the desired products. By amino acid sequence analysis and mass spectrometry,...
The recombinant hormone obtained by non-covalent interaction of the NH2-terminal 134 amino acid fragment with the COOH-terminal 51 amino acid fragment of the reduced-carbamidomethylated human somatotropin molecule is found to exhibit nearly full biological activity of the native hormone, as evidenced by the stimulation of hepatic ornithine decarboxylase (L-ornithine carboxy-lyase, EC 4.1.1.17) ...
Background and Objective: FSH is a heterodimeric glycoprotein that performs an important role in the regulation of reproductive processes. Over the past decades, injectable gonadotrophins have played a leading role in the treatment of infertility. The production of FSH in the country is one of the main goals around this drug. The aim of this study was to produce a semi- industrial recombinant F...
Insulin replacement therapy is the standard of care for patients with type 1 and advanced type 2 diabetes mellitus. Porcine and bovine pancreatic tissue was the source of the hormone for many years, followed by semisynthetic human insulin obtained by modification of animal insulin. With the development of recombinant DNA technology, recombinant (biosynthetic) human insulin became available in l...
Stimulation of the thyroid with thyroid-stimulating hormone (TSH) is a potentially useful diagnostic dysfunction, but little known about response to TSH stimulation in bottlenose dolphins (Tursiops truncatus). To better characterize dolphin stimulation, five adult participated study. Dolphins voluntarily beached onto padded mat and were given 1.5 mg intramuscular injection human recombinant TSH...
Background: The production of recombinant human growth hormone is usually problematic in Escherichia coli, and achieving higher functional protein yields economically important. Objectives: In this study, the chromosomal expression (hGH) araBAD operon was investigated using Rosetta-gami BL21 (DE3) competent cells under regulation arabinose T7 promoters inducer IPTG, respectively. Subsequently, ...
