Antiproliferative and differentiative effect of granulocyte-macrophage colony-stimulating factor on a variant human small cell lung cancer cell line.

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...

Expression of a Chimeric Protein Containing the Catalytic Domain of Shiga-Like Toxin and Human Granulocyte Macrophage Colony-Stimulating Factor (hGM-CSF) in Escherichia coli and Its Recognition by Reciprocal Antibodies

Fusion of two genes at DNA level produces a single protein, known as a chimeric protein. Immunotoxins are chimeric proteins composed of specific cell targeting and cell killing moieties. Bacterial or plant toxins are commonly used as the killing moieties of the chimeric immunotoxins. In this investigation, the catalytic domain of Shiga-like toxin (A1) was fused to human granulocyte macrophage ...

Optimization of secretory expression of recombinant hGM-CSF in high cell density cultivation of recombinant Escherichia coli using Taguchi statistical method

Human granulocyte macrophage colony stimulating factor (hGM-CSF) has many therapeutic applications.In this study, in order to verify the purification process, the effect of carbon source, IPTG concentration andpost-induction time on the secretion of recombinant hGM-CSF into the culture medium by recombinantEscherichia coli during high cell density cultivation were evaluated by...

Improvement in Development and Quality of 8 Cell Mouse Embryos in Presence of Granulocyte Macrophage-Colony Stimulating Factor

Purpose: Granulose Macrophage-Colony Stimulating Factor (GM-CSF) is a lympho- heamatopoietic actor, secreted in the reproductive system. Murine pre- implantation embryos express GM-CSF receptors. In his study, the capacity of eight cell mouse embryos was studied in the presence and absence of GM-CSF. Materials and Methods: Female NMRI mice were super ovulated using Pregnant Mare Serum gonadotr...

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