A novel neuroprotectant granulocyte-colony stimulating factor.

Comparison of T7- and Lac-Based Systems for the Periplasmic Expression of Human Granulocyte Macrophage Colony Stimulating Factor in Escherichia coli

Administration of recombinant human granulocyte colony-stimulating factor (rhG-CSF) for the intracranial hemorrhage in two dogs: a case report

Two dogs with generalized seizures were evaluated. The dogs were diagnosed with traumatic intracranial hemorrhages based on the history, neurological examinations, and magnetic resonance imaging (MRI) of the brain. Treatment was started with oxygen, prednisolone and anticonvulsant agents. No further seizure activity was observed after treatment in both dogs, however cushing reflex was detected ...

Induction of Apoptosis on K562 Cell Line and Double Strand Breaks on Colon Cancer Cell Line Expressing High Affinity Receptor for Granulocyte Macrophage-Colony Stimulating factor (GM-CSF)

Background: Immunotoxins are comprised of both the cell targeting and the cell killing moieties. We previously established a new immunotoxin, i.e. Shiga toxin granulocyte macrophage-colony stimulating factor (StxA1-GM-CSF), comprises of catalytic domain of Stx, as a killing moiety and GM-CSF, as a cell targeting moiety. In this study, the ability of the immunotoxin to induce apoptosis and dou...

The Expression of Human Granulocyte Macrophage Colony Stimulating Factor by Heat-Induction in Escherichia coli

A self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pL promoter, was constructed. The designed 5024 base pair expression plasmid contained a heat sensitive repressor cI857 coding gene to regulate the function of ?pL promoter under heat shock induction. Using the constructed vector,...

Expression and Secretion of Human Granulocyte Macrophage-Colony Stimulating Factor Using Escherichia coli Enterotoxin I Signal Sequence

With the aim of the secretion of human granulocyte macrophage-colony stimulating factor (hGM-CSF) in Escherichia coli, hGM-CSF cDNA was fused in-frame next to the signal sequence of ST toxin (ST-I) of exteroxigenic E. coli, containing 53 or 19 amino acids of signal peptide. The fused STsig::hGM-CSF coding fragments were inserted into a T7-based expression plasmid. The recombinant plasmids were ...

Production of Recombinant Human Granulocyte-Colony Stimulating Factor by Pichia pastoris

Human granulocyte-colony stimulating factor (hG-CSF) cDNA was expressed in the methylotrophic yeast Pichia pastoris under the control of the alcohol oxidase (AOX1) promoter. An expression vector for hG-CSF secretion was constructed using vector pPIC9. Higher levels of hG-CSF was obtained using a P. pastoris Mut+ (methanol utilization fast) phenotype. The effects of environmental factors such as...
