Pharmacokinetics of subcutaneous recombinant human granulocyte colony- stimulating factor in children

Pharmacokinetics of subcutaneous recombinant human granulocyte colony-stimulating factor in children.

Fifteen children (age 1.2 to 9.4 years) with advanced neuroblastoma were treated with myelosuppressive chemotherapy (cyclophosphamide, cisplatin, doxorubicin) followed by 5 (n = 5), 10 (n = 5), or 15 (n = 5) micrograms/kg recombinant granulocyte colony-stimulating factor (rG-CSF) subcutaneously (SC) once daily for 10 days, starting the day after chemotherapy. Serial serum samples obtained on da...

Overexpression of Recombinant Human Granulocyte Colony-Stimulating Factor in E. coli

Bakground: Granulocyte colony-stimulating factor (G-CSF) is a cytokine that stimulates hematopoiesis and induces proliferation and differentiation of granulocyte progenitor cells as well as production of bone marrow neutrophilic granulocyte colonies.  Nowadays, human recombinant G-CSF(hr G-CSF)is used for the treatment of chemotherapy- and radiotherapy-induced neutropenia, and also in patients ...

Efficient Process Development of Recombinant Human Granulocyte Colony-Stimulating Factor (rh-GCSF) Production in Escherichia coli

Background: The protein hormone granulocyte colony-stimulating factor (GCSF) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. Methods: An efficient process was developed for heterologous expression of human GCSF in E. coli BL21 (DE3). The feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...

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...
