Objective: To study the potential role of cellular macrophage colony-stimulating factor (cM-CSF) and cellular macrophage colony-stimulating factor receptor (cM-CSF-R) with breast cancer and hepatoma and search the way for clinical application. Methods: Frozen surgical specimens from 48 breast cancer patients, including 29 cases of histological grade II and 19 eases of grade III, and 16 hepatoma patients were investigated by Avidin Biotin Complex (ABC) immunohistochemical assay with anti-M-CSF monoclonal antibody (Mab) and anti-M-CSF-R Mab. Pathohistological examination was performed as well. Results: cM-CSF and cM-CSF-R were detected in tested specimens. The expression levels of cM-CSF and cM-CSF-R in grade III group were higher than in grade II group and more higher than control group hyperplasia of breast. Hepatoma tissues also showed higher expression level of cM-CSF and cM-CSF-R than normal adult and fetal liver. Conclusion: Breast cancer and hepatoma tissues presented higher expression levels of cM-CSF and cM-CSF-R than control and expression level might be related with tumor’s process. 展开更多

Objective: To verify the antigen association of MAF-J6-1 receptor with M-CSFR and to further study the role of M-CSF and its receptor mediated juxtacrine in promoting leukemic cell proliferation. Methods: Monoclonal antibody (McAb) of MAF-J6-1R RE2 and polyclonal antibody (PolyAb) of rhM-CSFR were prepared. The specificity of McAb RE2 to M-CSFR was confirmed by indirect ELISA, cross-neutralizing assay with J6-1 cell colony formation and neutralization test by ELISA. Results: the reactive activity of purified RE2 to M-CSFR was over 1: 16000. The inhibitory activity of M-CSFR and MAF-J6-1R could be blocked by RE2 and anti-M-CSFR antibody. The reactivity of RE2 to M-CSFR could be reduced by M-CSFR. Conclusion: The specificity of RE2 to M-CSFR was confirmed and the antigen association of MAF-J6-1R with M-CSFR was proved. It suggests that M-CSF and its receptor mediated auto-juxtacrine stimulation could be an operative mechanism in either leukemia or nonhematological malignancies. 展开更多

Objective: To investigate the potential role of macrophage colony-stimulating factor (M-CSF) and macrophage colony-stimulating factor receptor (M-CSF-R) on the growth of human hepatoma cells. Methods: Specimens of different origin, including tissues of human hepatocellular carcinoma (HCC), human fetal liver (FL) and normal liver (NL), the hepatoma cell lines, as well as the peripheral blood mononuclear cells (PBMC) from patients with HCC or liver metastatic tumor (LMT), were used to detect the expression levels of M-CSF and M-CSF-R by ABC immunohistochemistry staining and reverse transcription polymerase chain reaction methods the expression levels of M-CSF and M-CSF-R. Influence of monoclonal antibody against M-CSF (B5) or M-CSF-R (RE2) on proliferation ability of hepatoma cell linesin vitro was also studied. Results: The results showed that hepatoma tissues produced elevated levels of both M-CSF and M-CSF-R compared with those of fetal liver (P<0.001). The M-CSF/M-CSF-R expression levels of PBMC from hepatoma patients were higher than those of LMT patients (P<0.01,P<0.05) and the normal people (P<0.001). The hepatoma cell lines showed strong positive for M-CSF and M-CSF-R production. Both B5 and RE2 displayed a dose-dependent inhibitory effect on the growth and proliferation of hepatoma cells. Conclusion: The study indicates a co-expression model for M-CSF-R in hepatoma cells, suggesting an involvement of M-CSF/M-CSF-R in growth signaling of those malignant cells. The M-CSF/M-CSF-R seems to function through an autonomy mechanism in human hepatoma. 展开更多

Objective: To investigate the serum levels of soluble macrophage colony-stimulating factor receptor (M-CSFsR) in normal subjects and patients with hematological diseases and its clinical implications in hematological diseases. Methods: The concentration of M-CSFsR was determined by ELISA. The serum M-CSFsR was identified and characterized by immunoprecipitation and Western blotting. Results: The mean serum level of M-CSFsR of 123 normal individuals was 0.48 ng/ml ± 0.41 ng/ml. Immunoprecipitation and Western blotting assay revealed a ~ 90kD band of serum M-CSFsR. The mean serum M-CSFsR level of 60 patients with acute lymphoblastic leukemia (ALL), 36 patients with acute myeloblastic leukemia (AML), 13 patients with myelodysplastic syndrome (MDS) and 42 patients with aplastic anemia (AA) .were 0.22 ng/ml±0.23 ng/ml, 0.17 ng/ml±0.16 ng/ml, 0.19 ng/ml±0.16 ng/ml and 0.23 ng/ml±0.21 ng/ml, respectively, which were significantly lower than that of normal subjects (P=0.002 ,P<0.0001,P<0.0001 andP<0.0001). The mean serum M-CSFsR level of 51 idiopathic thrombocytopenic purpura (ITP) patients was significantly higher than that of normal subjects (2.05 ng/ml±2.75 ng/ml,P<0.0001). Conclusion: The serum M-CSFsR levels of patients with ALL, AML, MDS and AA were significantly lower, while the level of patients with ITP was significantly higher than that of normal individuals. Patients with severe ITP (platelet count<30×l09/L) had the highest M-CSFsR level. It suggested that the abnormal levels of serum M-CSFsR may associate with some hematological diseases and may contribute to the pathological process. 展开更多

Colony-stimulating factor 1 receptor (CSF-1R) is an important regulator of monocytes/macrophages (MO/MФ). Although several CSF-1R genes have been identified in teleosts, the precise role of CSF- 1R in ayu (Plecoglossus altivelis) remains unclear. In this study, we characterized the CSF-1R homologue from P. altivelis, and named it PaCSF-1R. Multiple sequence alignment and phylogenetic tree analysis showed that PaCSF-1R was most closely related to that of Japanese ricefish (Oryzias latipes). Tissue distribution and expression analysis showed that the PaCSF-1R transcript was mainly expressed in the head kidney-derived MO/MФ, spleen, and head kidney, and its expression was significantly altered in various tissues upon Vibrio anguillarum infection. After PaCSF-1R neutralization for 48 h, the phagocytic activity of MO/MФ was significantly decreased, suggesting that PaCSF-1R plays a role in regulating the phagocytic function of ayu MO/M(P. 展开更多

The counter receptor was presented. Membrane bound macrophage colony-stimulating factor (m-M-CSF) and its receptor (M-CSF-R) were shown in human leukemic cell line J6-1 as autojuxtacrine mechanism. Soluble M-CSF receptor (sM-CSF-R), which was isolated from J6-1 cells membrane, was added into J6-1 cell culture. It was observed inhibition of J6-1 cell proliferation, decreasing of mitosis index and ratio of multinuclear cells, enlargement of cell diameter and volume, down regulation of numerous surface antigens. Dramatic change of intracellular pH was shown between several min to 20 min after treatment of sM-CSF-R. It suggested that some information was transmitted via m-M-CSF from sM-CSF-R. This counter signaling was not influenced by saccharification of m-M-CSF. 展开更多

Colony-stimulating factor-1 (CSF-1), which is necessary for cell proliferation and differentiation, regulates both immediate and delayed early responses throughout G1 phase. The binding of CSF-1 to its receptor (CSF-1R) triggers phosphorylation of the receptor and its intrinsic tyrosine kinase. The activated receptor binds directly to cytoplasmic effector proteins, which induce multiple-signal transduction pathways. CSF-1 can induce the c-myc gene expression via Ras and Ets-related proteins. The expression of c-fos/jun family genes is also targeted following the activation of Ras. CSF-1R activates STAT1 and STAT3 to participate in signaling, but JAKs do not appear to contribute to signaling by CSF-1R. CSF-1R activates PI3-kinase, and PI3-kinase can interact with downstream proteins by the MAPKK-related pathway independent of Ras/Raf. PC-PLC can enforce signaling in response to CSF-1. Furthermore, the turnover and dephosphorylation by the phosphatase SHPTP1 of CSF-1R are the major mechanism in the negative regulation of signaling by CSF-1R. 展开更多

AIM: To investigate the therapeutic efficacy and mechanisms of action of oncolytic-herpes-simplex-virus encoding granulocyte-macrophage colony-stimulating factor(HSVGM-CSF) in pancreatic carcinoma.METHODS: Tumor blocks were homogenized in a sterile grinder in saline.The homogenate was injected into the right armpit of each mouse.After vaccination,the mice were randomly assigned into four groups: a control group,a high dose HSVGM-CSFgroup [1 × 107plaque forming units(pfu)/tumor],a medium dose HSVGM-CSF group(5 × 106pfu/tumor) and a low dose HSVGM-CSF group(5 × 105pfu/tumor).After initiation of drug administration,body weights and tumor diameters were measured every 3 d.Fifteen days later,after decapitation of the animal by cervical dislocation,each tumor was isolated,weighed and stored in 10% formaldehyde solution.The drug effectiveness was evaluated according to the weight,volume and relative volume change of each tumor.Furthermore,GM-CSF protein levels in serum were assayed by enzyme-linked immunosorbent assays at 1,2,3 and 4 d after injection of HSVGM-CSF.RESULTS: Injection of the recombinant mouse HSV encoding GM-CSF resulted in a significant reduction in tumor growth compared to the control group,and dosedependent effects were observed: the relative tumor proliferation rates of the low dose,medium dose and high dose groups on 15 d after injection were 45.5%,55.2% and 65.5%,respectively.The inhibition rates of the tumor weights of the low,middle,and high dose groups were 41.4%,46.7% and 50.5%,respectively.Furthermore,the production of GM-CSF was significantly increased in the mice infected with HSVGM-CSF.The increase in the GM-CSF level was more pronounced in the high dose group compared to the other two dose groups.CONCLUSION: Our study provides the first evidence that HSVGM-CSFcould inhibit the growth of pancreatic cancer.The enhanced GM-CSF expression might be responsible for the phenomenon. 展开更多

Adult, male, Sprague-Dawley rats were injected with granulocyte-macrophage colony-stimulating factor-transfected bone marrow stromal cells (GM-CSF-BMSCs) into the ischemic boundary zone at 24 hours after onset of middle cerebral artery occlusion. Results showed reduced infarct volume, decreased number of apoptotic cells, improved neurological functions, increased angiogenic factor expression, and increased vascular density in the ischemic boundary zone in rats that underwent GM-CSF-BMSCs transplantation compared with the BMSCs group. Experimental findings suggested that GM-CSF-BMSCs could serve as a potential therapeutic strategy for ischemic stroke and are superior to BMSCs alone. 展开更多

Objective: To explore the effects of nuclear M-CSF on the process of tumorigenesis. Methods: Functional part of M-CSF cDNA was inserted into an eukaryotic expression plasmid pCMV/myc/nuc, which can add three NLS to the C-terminal of the expressed protein and direct the protein into the cell nuclei. The constructed plasmid was transferred into NIH3T3 cells and the cell clones were selected by G-418 selection. Cell clones stable expressing target protein were identified by RT-PCR, ABC immunohistochemistry assayand Western blot. Cell growth kinetics analyses throughgrowth curves, cell doubling time, MTT test and anti-sense oligodeoxynucleotide (ASODN) inhibiting cell growth testwere performed to identify cells proliferation potential.Results: The transfected cells showed elevated proliferation potential over the control cells. Conclusion: Abnormalappearance of M-CSF in nucleus could enhance cellproliferation, which suggests that cytokine isoforms within cell nucleus might play transcription factor-like role. 展开更多

A recombinant vaccinia virus expressing murine granulocyte-macrophage colony-stimulating factor (VVGM-CSF) was tested for its antitumor activity.Murine pulmonary metastasis was established by injecting 20×10~5 B16F10 melanoma cells into the tail vein of C57BL/6 mice. Three days after B16F10 inoculation,WGM-CSF or VVTK, a thymidine kinase gene deficient control vaccinia virus, were injected intraperitoneally twice weekly for 2 weeks. Two weeks later, the mice were sacrificed and pulmonary metastasis fool counted.The results demonstrated that VVGM-CSF treatment significantly decreased the number of pulmonary metastasis and prolonged the survival time of tumorbearing mice. Cytotoxic and phagocytic activities of the peritoncal macrophages were found to be markedly elevated in mice treated with WGM-CSF. Nitric oxide released from the macrophages was also found to be increased. These data, together with our other results,strongly demonstrated that continuous secretion of GMCSF and activation of macrophages might pal-tially explain the therapeutic effects of VVGM-CSF on murine pulmonary metastasis. 展开更多

Cells, pretreated with the recombinant human macrophage colony-stimulating factor (rhM-CSF) expressed in silkworm larvae, were inoculated with several viruses to observe the effect of rhM-CSF on viral replication. The results showed that in cultures of fibroblast derived from human fetal skin-muslce tissues infected with the viruses (including VSV, rhinovirus, influenza virus type A3, HSV-1, HSV-2, adenovirus type 6 and type 11), rhM-CSF inhibited the virus-induced cytopathy, which defered or relieved the cytophathy and that in the cells derived from breast feeding rabbit kidney infected with HSV-1, rhM-CSF reduced titer of the virus in a rhM-CSF dose-dependent pattern,in which rhM-CSF with the dose of 1×106 U/L made the viral titer drop dwon over 200 times. This antiviral activity of rhM-CSF could be partially neutralized by anti-IFN-βMcAb, but not by antiTNF-α, anti-IFN-α, or anti-IFA-γ McAb, indicating the mechanism of the antiviral activity of MCSF is related to the induction of IFN-β. 展开更多

The G-CSF is used as a therapeutic drug of the febrile neutropenia in lung cancer chemotherapy, however, there were few reports that showed the effects of combination effects of G-CSF and anticancer drugs against lung cancer. In the present study, we investigated the effects of G-CSF and the combination effects of G-CSF and cisplatin on lung cancer growth. We investigated the effect of G-CSF against the LL-2 and KLN-205 cells by MTT assay and tried to detect the G-CSF receptor by RT-PCR. Next, to analyze the G-CSF effects in vivo, we transplanted the LL-2 into C57BL/6 mice, intraperitoneally administered G-CSF (30 micro/kg/day) with or without cisplatin (5 mg/kg), measured the tumor size and analyzed pathologically by HE and immunostaining. In vitro analyses, G-CSF showed no effects in LL-2 and KLN-205 cells, and RT-PCR revealed no G-CSF receptor mRNA. In vivo analyses, G-CSF alone did not significantly suppress tumor growth. However, concurrent G-CSF administration with cisplatin significantly enhanced the tumor suppressing effect of cisplatin in early stage of tumor growth. The analysis data of vWF immunostaining indicated that the neovascularization in the peripheral region of the tumors was more enhanced in G-CSF treatment mice. ELISA assay revealed that G-CSF did not influence the serum concentration of TNF-alpha and IL-12 in tumor-bearing mice. This study suggests that concurrent (combination) administration of cisplatin with G-CSF is a safe and effective method for enhancing anticancer effects and reducing chemotherapeutic agent-induced myelosuppression. 展开更多

Objective To observe the efficacy of treating intrauterine infected chronic hepatitis B virus (HBV) carrier children with a combination of granulocyte macrophage colony stimulating factor (GM CSF) or hepatitis B immunoglobulin (HBIG) plus recombinant hepatitis B vaccine (rHBvac) Methods A total of 27 chronic HBV infected children, who were born to HBV carrier mothers and received hepatitis B immunoprophylaxis at birth, were randomized into 2 groups: one receiving a combined therapy of 50 μg of GM CSF plus 10 μg of rHBvac injected intramuscularly at the same location (GM CSF group, 14 children) or 200 IU HBIG and 10 μg rHBvac in different muscles (HBIG group, 13 children) on a monthly four dose schedule HBV DNA quantification and other HBV serological markers were tested before and after the four dose therapy Results Twelve children in each group completed the study Of them, 3 children in the GM CSF group and 4 in the HBIG group had elevated serum alanine transaminase (ALT) before the trial, and then 2 in each group became ALT normal after the treatment Before the therapy, hepatitis B e antigen (HBeAg) positivity was found in nine children in the GM CSF group and 10 in the HBIG group One from each group had an HBeAg/anti HBe seroconversion after the treatment The quantity of HBV DNA was significantly lower after the treatment ( P =0 023) in GM CSF group, but was not significantly reduced in HBIG group No subjects were found to be negative for hepatitis B surface antigen (HBsAg) after the treatment, and no serious adverse events occurred in either group Conclusion Combined GM CSF and rHBvac therapy inhibit HBV replication in carrier children who were not protected after treatment with immunoprophylaxis 展开更多
