Granulocyte colony stimulating factor (G-CSF) plays a major role in the proliferation, differentiation, and activation of neutrophil cell line hematopoietic cells. G-CSF exert the function depending on its binding to colony-stimulating factor 3 receptor (CSF3R), a homo-dimer receptor located on the surface of effector cells. Some recent studies have demonstrated that CSF3R mutations play a significant role in many diseases. Some of the hematopoietic diseases, especially myeloid malignancies (e.g. chronic neutrophilic leukemia) are related to the presence of various CSF3R mutations, which leads to abnormal G-CSF signal pathways. Also, the downstream kinases can be the treatment targets for these diseases. This review summarizes CSF3R mutations, mechanisms of mutations, and their contributions to the myeloid malignancies, with an attempt to further reveal the pathogenesis of myeloid malignancies, inform the diagnosis and clinical treatment of the myeloid malignancies, and provide clues for the research and development of new molecular target drugs.

OBJECTIVE: To investigate the influence of granulocyte colony stimulating factor (G-CSF) and granulocyte macrophage colony stimulating factor (GM-CSF) on preimplantation development and implantation in mouse embryos. MATERIAL AND METHODS: Eight-cell stage mouse embryos were cultured for 96 hours with G-CSF or GM-CSF at concentrations of 10 pg/ml, 100 pg/ml, 1 ng/ml and 10 ng/ml. Embryos not treated with G-CSF or GM-CSF were served as control. The percentages of embryos which developed to expanded, hatched blastocyst stage and in vitro implantation at 96 hours were determined. Results were analyzed with Kolmogorov-Smirnov test and analysis of variance (ANOVA). The statistical significance was defined as p<0.05. RESULTS: The percentages of fully expanded blastocysts in all G-CSF and GM-CSF treatment groups were not significantly different from the control. The percentages of hatched blastocysts were significantly higher in 100 pg/ml and 10 ng/ml of G-CSF treatment group compared to the control (p<0.05, p<0.05, respectively). The percentages of hatched blastocysts were significantly lower in 1 ng/ml of GM-CSF treatment group compared to the control, 10 pg/ml, and 100 pg/ml of GM-CSF treatment group (p<0.05, p<0.05, p<0.05, respectively), and the percentages of hatched blastocysts were also significantly lower in 10 ng/ml of GM-CSF treatment group compared to the control and 100 pg/ml of GM-CSF treatment group (p<0.05, p<0.05, respectively). The percentages of implanted blastocysts in vitro were significantly higher following incubation with all concentrations of G-CSF compared to the control and, especially in 100 pg/ml and 10 ng/ml of G-CSF treatment groups compared to the control and other treatment groups. The percentages of implanted blastocysts in vitro were significantly higher in 10 pg/ml of GM-CSF treatment group than the control and 100 pg/ml of GM-CSF treatment groups (p<0.05, p<0.05, respectively). CONCLUSION: G-CSF and GM-CSF might influence on embryonic development and implantation in mouse embryos.

BACKGROUND: As an attempt to develop a strategy to improve the protective immune response to GM-CSF-secreting CT26 (GM-CSF/CT26) tumor vaccine, we have investigated whether the apoptogenic treatment of GM-CSF/CT26 prior to vaccination enhances the induction of anti-tumor immune response in mouse model. METHODS: A carcinogen- induced mouse colorectal tumor, CT26 was transfected with GM-CSF gene using a retroviral vector to generate GM-CSF-secreting CT26 (CT26/GM-CSF). The CT26/GM-CSF was treated with gamma-irradiation or mitomycin C to induce apoptosis and vaccinated into BALB/c mice. After 7 days, the mice were injected with a lethal dose of challenge live CT26 cells to examine the protective effect of tumor vaccination in vivo. RESULTS: Although both apoptotic and necrotic CT26/GM-CSF vaccines were able to enhance anti-tumor immune response, apoptotic CT26/GM-CSF induced by pretreatment with gamma-irradiation (50,000 rads) was the most potent in generating the anti-tumor immunity, and thus 100% of mice vaccinated with the apoptotic cells remained tumor free for more than 60 days after tumor challenge. CONCLUSION: Apoptogenic pretreatment of GM-CSF-secreting CT26 tumor vaccine by gamma-irradiation (50,000 rads) resulted in a significant enhancement in inducing the protective anti-tumor immunity. A rapid induction of apoptosis of CT26/GM-CSF tumor vaccine at the vaccine site might be critical for the enhancement in anti-tumor immune response to tumor vaccine.

Granulocyte macrophage-colony stimulating factor (GM-CSF) occupies a central position in the regulation of hematopoietic responses. GM-CSF not only signals proliferations of granulocyte-macrophage but also drives these cells into differentiation and activates mature cells of the GM-CSF sensitive lineage. Myelosuppression that is induced by M-VAC (methotrexate, vinblastine, doxorubicin, cisplatinum) chemotherapy brings many problems in successful treatment such as sepsis, dose reduction, delaying the schedule. Granulocyte-macrophage colony stimulating factor is introduced hopefully as a new solution for these problems. So we evaluated the efficacy and safety of GM-CSF in leukopenia induced by M-VAC chemotherapy in patients with urothelial cancer. GM-CSF was administered at 200ug subcutaneously in 10 M-VAC cycles of 6 patients on 5th and 6th day after M-VAC therapy. Sixteen cycles, by which only M-VAC chemotherapy was administered without GM-CSF. of the other 6 patients served as control group. Mean white blood cell count in peripheral blood at M-VAC 2nd day and 15th day was 5,630/mm3 and 4,240/mm3 in GM-CSF administered cycles, 6,58l/mm3and 3,613/mm3 in non GM-CSF administered cycles. There was no delayed cycle in administration of MTX and vinblastine at M-VAC 15th day in the cycles with GM-CSF. There was no significant side effects caused by GM- CSF. The result indicates that GM-CSF can be used safely and effectively against leukopenia after M-VAC chemotherapy of urothelial cancer.

BACKGROUND: Tattoos are acquired pigmented lesions of the skin, and the Q-switched alexandrite laser has been shown to be effective in removing blue-black as well as green, red and mauve colored tattoos. Following the laser therapy, macrophage phagocytes the altered pigment. Macrophage-colony stimulating factor(M-CSF) may influence the macrophage activities. OBJECTIVE: This study was conducted to evaluate the potential adjunctive effect of M-CSF in tattoo removal with laser treatment. METHOD: A prospective study was taken, in 8 guinea pigs and 8 mice, to evaluate the clinical and histopathological clearing of tattoo pigment following the laser treatment of the tattoo at the M-CSF injection site. RESULTS: 1) Clinically, the tattoo resolved more rapidly with Alexandrite laser therapy in the M-CSF treated group. 2) Histopathologically, by using image analysis, there was no significant difference in the relative ratio of dermal tattoo pigment and tattoo containing cells, between laser treated(1.54% in guinea pig, 1.09% in mouse) and laser with M-CSF treated group(1.44% in guinea pig, 0.95% in mouse). CONCLUSION: Our study reveals the role of M-CSF as an adjuvant in tattoo removal using Alexandrite laser surgery. However, further prospective animal studies and human trials, are needed to evaluate the action mechanism of M-CSF at the intradermal injection.

There is increasing evidence that airway epithelial cells, when exposed to various gas-derived air pollutants, play an important role in airway inflammation by releasing inflammatory cytokines. However, there is little information on air pollutant-induced cytokine expression at the tissue level and on the role of sulfur dioxide (SO2), one of the major ambient air pollutants, in cytokine production. We studied whether or not a low concentration of sulfur dioxide induces an increase in tissue expression of interleukin-4 (IL-4), interleukin-8 (IL-8), and granulocyte/macrophage colony stimulating factor (GM-CSF). After exposing surgically obtained normal human nasal turbinates to 0.05 ppm SO2 for one hour, we conducted specific immunohistochemical staining to assess the tissue expression of each cytokine. We found that the percent expression of IL-8 and GM-CSF in the surface epithelium was significantly higher in each SO2-exposed tissue than in the matched control tissue. However, there was no significant difference in the number of submucosal IL-4-positive cells between exposed and control specimens. These results suggest that exposure to a low concentration of SO2 increases airway inflammation, apparently by inducing an increase in the expression of GM-CSF and IL-8.

Pulmonary alveolar proteinosis (PAP) is a rare condition that is treated using whole lung lavage. A recent study suggested that granulocyte-macrophage colony stimulating factor (GM-CSF) plays roles in both the pathogenesis and treatment of PAP. We present a 69-year-old man with PAP who deteriorated despite bilateral whole lung lavage; that said, his symptoms, chest X-ray findings, and pulmonary function test improved after GM-CSF inhalation therapy over 12 months. GM-CSF therapy is an effective treatment modality for PAP.

OBJECTIVE: Granulocyte-macrophage colony stimulating factors known to be secreted in murine and human reproductive tract. The development of human, bovine and murine embryos could be promoted by addition of GM-CSF in culture medium. However, the pregnancy and implantation rate of embryos cultured in GM-CSF have not been evaluated. The aim of this study was to assess the effect of GM-CSF in embryo development, pregnancy and implantation rate. METHODS: A total of 191 IVF cycles were divided into control and GM-CSF supplement group (control =96, GM-CSF=95). The embryos were cultured for three day with or without 2 ng/ml of recombinant human GM-CSF. The quality of embryo, developmental velocity, pregnancy and implantation rates were compared. RESULTS: There was no difference in age, number of gonadotropin ampules used, number of oocytes and fertilization. The number of ICSI cycle was higher in GM-CSF group. In GM-CSF group, G-1 grade embryos were the highest in proportion (56.4%), while G-2 grade embryos were highest (44.3%) in control group. The developmental velocity of embryos were not different between GM-CSF and control group. The pregnancy and implantation rates were significantly higher in GM-CSF group than control (47.4% vs. 33.3%, 17.0% vs. 11.1% respectively). CONCLUSION: By adding GM-CSF in culture medium, the quality of embryo, pregnancy and implantation rate could be improved.
