Application of pegylated recombinant human granulocyte colony-stimulating factor(PEG-rhG-CSF) for the prevention of neutropenia in triple negative breast cancer patients older than 65 years during adjuvant chemotherapy

Objective The aim of this study was to compare the efficacy and safety of pegylated recombinant human granulocyte colony-stimulating factor(PEG-rhG-CSF)and recombinant human granulocyte colonystimulating factor(rhG-CSF)for the prevention of neutropenia in elderly breast cancer patients during adjuvant chemotherapy.Methods A total of 45 oncology inpatients with breast cancer,who received adjuvant chemotherapy and were older than 65 years from May 2017 to October 2018 in the General Hospital of the Northern Theater of the Chinese people’s Liberation Army,were included.Epirubivin Cyclophoshamide-Docetaxel(EC-T)sequential adjuvant chemotherapy was chosen.Forty-five patients were randomly divided into two groups;25 patients in the treatment group were treated with PEG-rhG-CSF and 20 patients in the control group were not treated with PEG-rhG-CSF,but only rhG-CSF.The experimental group was treated with the PEG-rhG-CSF at the end of chemotherapy for 24–48 h,with a 6 mg subcutaneous injection once per chemotherapy cycle.In the control group,rhG-CSF was administered after 48 h of chemotherapy,with a 100μg subcutaneous injection,1/d,d 1–7.The dosage could be increased step by step with the exacerbation of neutropenia.The primary aims of this study was to discover the incidence of leukopenia,neutropenia,neutrophilic fever,and adverse reactions in the two groups.Results The incidence of neutropenia,neutrophilic fever and adverse reactions decreased in the treatment group compared to the control group,but no significant difference existed between two groups(P>0.05).Patients in treatment group had a lower,but not statistically significant,incidence of adverse reactions(P>0.05).Conclusion Applying PEG-rhG-CSF could be effective in preventing neutropenia in elderly patients with postoperative adjuvant chemotherapy to treat breast cancer.It may effectively control the occurrence of neutropenia after chemotherapy and reduce the chance of infection.The incidence of side effects,such as fever and bone pain,was low.The adverse drug reactions were well tolerated by patients,which could ensure the smooth progress of chemotherapy.

Pharmacokinetic Study of a Novel Recombinant Human Granulocyte Colony-stimulating Factor in Rats

Objective To study the pharmacokinetics of a novel recombinant human granulocyte colonystimulating factor (rhG-CSFa) in rats and to determine the proteolytic rates of rhG-CSFa in the whole blood and serum of rats in vitro. Methods The pharmacokinetics of rhG-CSFa and conventional (wild type,WT) granulocyte colonystimulating factor (G-CSF) were investigated in Sprague-Dawley rats which received either intravenous or subcutaneous injection of rhG-CSFa or WT G-CSF at three different doses (20,50,or 100 μg/kg). The blood samples of rats were collected at multiple time points (from 0.08 to 12 h) and the concentrations of rhG-CSFa and WT G-CSF in serum were determined with a sandwich enzyme-linked immunosorbent assay (ELISA). For the study of proteolytic rates in vitro,the concentrations of rhG-CSFa or WT G-CSF were determined at 3-minute intervals after addition of the respective drug to rat’s whole blood or serum. Results Pharmacokinetic analysis of serum rhG-CSFa or WT G-CSF levels indicated that,at each dose tested,for either route of drug administration,the area under concentration-time curve values and the maximum serum concentration of rhG-CSFa were higher than those of WT G-CSF,and the serum half life of rhG-CSFa was longer than that of WT G-CSF. Subsequent in vitro whole blood and serum stability study showed that the rates of drug degradation in WT G-CSF were 1.8 folds and 1.5 folds higher than those in rhG-CSFa,respectively. Conclusion rhG-CSFa has better serum and whole blood stability in vitro and higher bioavailability in vivo as compared to WT G-CSF.

Refolding with Simultaneous Purification of Recombinant Human Granulocyte Colony-stimulating Factor from Escherichia coli Using Strong Anion Exchange Chromatography

The urea denatured recombinant human granulocyte colony-stimulating factor (rhG- CSF) which was expressed in Escheriachia coli (E. coli) was refolded with simultaneous purification by strong anion exchange chromatography (SAX) in the presence of low concentration- of urea. The effect of urea concentration on this refolding process was investigated. The obtained refolded rhG-CSF has a high specific activity of 2.3×108 U/mg, demonstrating that the proteins were completely refolded during the chromatographic process. With only one step by SAX in 40 min, purity and mass recovery of the refolded and purified rhG-CSF were 97% and 43%, respectively.

Anti-apoptotic effects of recombinant human granulocyte colony-stimulating factor in focal cerebral ischemic rats

The neuroprotective effects of granulocyte colony-stimulating factor in cerebral ischemia/reperfusion injury are currently contentious. The present study examined the effects of subcutaneous injection of recombinant human granulocyte colony-stimulating factor （50 pg/kg） over 5 days in a model of cerebral ischemia/reperfusion with intraluminal filament occlusion in rats. The results indicated that recombinant human granulocyte colony-stimulating factor reduced brain infarct volume following cerebral ischemia/reperfusion injury in rats, down-regulated the expression of caspase-3 mRNA （a key protease for apoptosis in the cerebral ischemia zone）, lowered the rate of neuronal apoptosis in the cerebral ischemia zone, and notably ameliorated neurological function. These results indicate that recombinant human granulocyte colony-stimulating factor has anti-apoptotic effects on neurons following focal cerebral ischemia/reperfusion injury, and exerts neuroprotective effects.

A New Protocol for Solubilization, Refolding and Purification of Recombinant Human Granulocyte Colony-stimulating Factor in Inclusion Bodies

Recombinant human granulocyte colony-stimulating factor （rhG-CSF） in inclusion bodies was solubilized by 8 mol/L urea solution and subsequently precipitated by acetone to improve its purity. After that, the precipitates were solubilized by sodium hydroxide solution containing 2 mol/L urea. Then the solubilized rhG-CSF was passed through a size exclusion chromatography for refolding and extensive purification, and further purified by a weak anion exchange chromatography. The purity and mass recovery of refolded rhG-CSF were 96.5% and 75.6%, respectively. The bioactivity was 8.4x10^7 IU/mg.

Bioactive materials from berberine-treated human bone marrow mesenchymal stem cells promote alveolar bone regeneration by regulating macrophage polarization

Alveolar bone regeneration has been strongly linked to macrophage polarization.M1 macrophages aggravate alveolar bone loss,whereas M2 macrophages reverse this process.Berberine(BBR),a natural alkaloid isolated and refined from Chinese medicinal plants,has shown therapeutic effects in treating metabolic disorders.In this study,we first discovered that culture supernatant(CS)collected from BBR-treated human bone marrow mesenchymal stem cells(HBMSCs)ameliorated periodontal alveolar bone loss.CS from the BBR-treated HBMSCs contained bioactive materials that suppressed the M1 polarization and induced the M2 polarization of macrophages in vivo and in vitro.To clarify the underlying mechanism,the bioactive materials were applied to different animal models.We discovered macrophage colony-stimulating factor(M-CSF),which regulates macrophage polarization and promotes bone formation,a key macromolecule in the CS.Injection of pure M-CSF attenuated experimental periodontal alveolar bone loss in rats.Colony-stimulating factor 1 receptor(CSF1R)inhibitor or anti-human M-CSF(M-CSF neutralizing antibody,Nab)abolished the therapeutic effects of the CS of BBR-treated HBMSCs.Moreover,AKT phosphorylation in macrophages was activated by the CS,and the AKT activator reversed the negative effect of the CSF1R inhibitor or Nab.These results suggest that the CS of BBR-treated HBMSCs modulates macrophage polarization via the M-CSF/AKT axis.Further studies also showed that CS of BBR-treated HBMSCs accelerated bone formation and M2 polarization in rat teeth extraction sockets.Overall,our findings established an essential role of BBR-treated HBMSCs CS and this might be the first report to show that the products of BBR-treated HBMSCs have active effects on alveolar bone regeneration.

Granulocyte Colony-stimulating Factor-primed Bone Marrow： An Excellent Stem-cell Source for Transplantation in Acute Myelocytic Leukemia and Chronic Myelocytic Leukemia

Background：Steady-state bone marrow （SS-BM） and granulocyte colony-stimulating growth factor-primed BM/peripheral blood stem-cell （G-BM/G-PBSC） are the main stem-cell sources used in allogeneic hematopoietic stem-cell transplantation.Here,we evaluated the treatment effects of SS-BM and G-BM/G-PBSC in human leucocyte antigen （HLA）-identical sibling transplantation.Methods：A total of 226 patients （acute myelogenous leukemia-complete remission 1,chronic myelogenous leukemia-chronic phase 1） received SS-BM,G-BM,or G-PBSC from an HLA-identical sibling.Clinical outcomes （graft-versus-host disease [GVHD],overall survival,transplant-related mortality [TRM],and leukemia-free survival [LFS]） were analyzed.Results：When compared to SS-BM,G-BM gave faster recovery time to neutrophil or platelet （P 〈 0.05）.Incidence of grade Ⅲ-Ⅳ acute GVHD and extensive chronic GVHD （cGVHD） was lower than seen with SS-BM （P 〈 0.05） and similar to G-PBSC.Although the incidence of cGVHD in the G-BM group was similar to SS-BM,both were lower than G-PBSC （P 〈 0.05）.G-BM and G-PBSC exhibited similar survival,LFS,and TRM,but were significantly different from SS-BM （P 〈 0.05）.There were no significant differences in leukemia relapse rates among the groups （P 〉 0.05）.Conclusions：G-CSF-primed bone marrow shared the advantages of G-PBSC and SS-BM.We conclude that G-BM is an excellent stem-cell source that may be preferable to G-PBSC or SS-BM in patients receiving HLA-identical sibling hematopoietic stem-cell transplantation.
