Production of recombinant Somatostatin
The synthesis of recombinant human somatostatin led to the commercial human recombinant insulin production.
Synthesis of both somatostatin-28 and somatostatin-25 ..
Two research groups, one at the University of California, San Francisco, and the other at Genentech, a company specializing in recombinant DNA technology in South San Francisco, last week announced independent syntheses of this hormone.
Earlier work at Genentech includes the synthesis of the small peptide hormone somatostatin using recombinant DNA technology together with chemical synthesis of the needed DNA sequence, ...
Prospective of 68Ga-Radiopharmaceutical Development
The entire goal and desire of recombinant DNA is to provide a strategy for treatment of genetic conditions, maximisation of animal production using gene injection; change in genome of agricultural products to provide more germ resistant transgenic varieties of crops or animals, production of blood products, factors or hormones (such as human insulin, somatostatin etc), design of new drugs after the synthesis of its receptors from its genes, and the exploitation of the human genome project with the use of numerous known human genes to synthesize new peptide products for treatment of diverse disease conditions in man.
Recombinant DNA therefore is the study of DNA and how to manipulate it in order to provide sequence of genes which will give useful knowledge about synthesis of such genes, synthesis of complementary DNA, cloning or amplification of the synthesized gene, use of the gene for translation in vitro to produced its peptide products which may be useful therapeutically, biologically or agriculturally and development of gene probes for diagnosis of the presence of genes in embryos, fetuses and adults.

We hypothesized that in the absence of ligand, SSTR3 exhibits constitutive receptor activity, which regulates GH synthesis. The ability to rigorously assess constitutive receptor activity requires the identification of naturally occurring mutants as well as the availability of inverse agonists, neither of which exist for SSTR3. Mutation of the DRY (aspartate-arginine-tyrosine) motif located within the third transmembrane domain and second intracellular loop transition, conserved in all 5 SSTRs, interferes with an “ionic lock” salt bridge stabilizing the GPCR in an inactive conformation, thereby attenuating constitutive receptor activity (). Using rat pituitary GC cells, devoid of both endogenous rSstr3 and somatostatin, but expressing low levels of endogenous rSstr2, we generated stable wild-type (WT) and DRY mutant (R141A) SSTR3 transfectants. We observed that ligand-independent SSTR3 activity inhibits basal cAMP/PKA signaling and suppresses GH transcription through GSK3-β activation.
Several signaling pathways regulate GH gene expression. GH-releasing hormone up-regulates GH transcription via activation of the adenylate cyclase–cAMP–protein kinase A pathway (–) as does mitogen-activated protein kinase activation in GH3 cells () and gsp oncogene-expressing GH4C1 cells (). Core histone acetylation was shown to regulate the human GH locus control region to facilitate GH promoter transfactor binding and transcription activation (). Furthermore, dopamine receptor subtype 2, also a Gαi coupling GPCR that inhibits prolactin (PRL) and is also expressed in somatotrophs, induced rapid histone deacetylation of the PRL promoter (). In light of these observations, we assessed whether constitutive SSTR2 activity regulates recombinant (r) GH promoter deacetylation and subsequent rGH synthesis.

Both groups have long experience in the use of recombinant DNA techniques to make peptides with potential drug applications. Two years ago a group at UCSF was the first to insert rat insulin genes into bacteria (C&EN, May 30,1977, page 4). Then researchers there cloned the first gene for a human hormone, that for somatomammotropin, a placental lactogen. Last January, they announced the synthesis in bacteria of rat growth hormone.

Protocols are developed to rapidly sequence long sections of DNA. Genetically engineered bacteria are used to synthesize the human growth protein somatostatin, marking the first time a synthetic recombinant gene is used to clone a protein. Many consider this to be the advent of the Age of Biotechnology. Dr. Robert Austrian of the University of Pennsylvania develops the first vaccine for pneumonia.

Effects of Human Growth Hormone in Men over 60 Years Old
The first human artificial chromosome is created. A combination of natural and synthetic DNA is used to create a genetic cassette that can potentially be customized and used in gene therapy. The FDA approves a recombinant follicle stimulating hormone to treat infertility. The FDA approves the first bloodless HIV-antibody test that uses cells from patients' gums. Scientists at the Institute for Genomic Research sequence the complete genome of the Lyme disease pathogen, Borrelia burgdorferi, along with the genome for the organism linked to stomach ulcers, Helicobacter pylori. Scientists at the University of Wisconsin–Madison sequence the E coli genome. The FDA approves the first therapeutic antibody to treat cancer in the United States. It is used for patients with non-Hodgkin's lymphoma.
