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 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 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

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

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

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

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

Microglia are the brain’s primary innate immune cells,and they are activated and affect pro-inflammatory phenotype or regulatory phenotype after ischemic stroke.Vagus nerve stimulation was shown to activate microglial phenotypic changes and exhibit neuroprotective effects in ischemia/reperfusion injury.In this study,we established rat models of ischemic stroke by occlusion of the middle cerebral artery and performed vagus nerve stimulation 30 minutes after modeling.We found that vagus nerve stimulation caused a shift from a pro-inflammatory phenotype to a regulatory phenotype in microglia in the ischemic penumbra.Vagus nerve stimulation decreased the levels of pro-inflammatory phenotype markers inducible nitric oxide synthase and tumor necrosis factorαand increased the expression of regulatory phenotype markers arginase 1 and transforming growth factorβthrough activatingα7 nicotinic acetylcholine receptor expression.Additionally,α7 nicotinic acetylcholine receptor blockade reduced the inhibition of Toll-like receptor 4/nuclear factor kappa-B pathwayassociated proteins,including Toll-like receptor 4,myeloid differentiation factor 88,I kappa B alpha,and phosphorylated-I kappa B alpha,and also weakened the neuroprotective effects of vagus nerve stimulation in ischemic stroke.Vagus nerve stimulation inhibited Toll-like receptor 4/nuclear factor kappa-B expression through activatingα7 nicotinic acetylcholine receptor and regulated microglial polarization after ischemic stroke,thereby playing a role in the treatment of ischemic stroke.Findings from this study confirm the mechanism underlying vagus nerve stimulation against ischemic stroke. 展开更多

Studies have shown that repetitive transcra nial magnetic stimulation(rTMS)can enhance synaptic plasticity and improve neurological dysfunction.Howeve r,the mechanism through which rTMS can improve moderate traumatic brain injury remains poorly understood.In this study,we established rat models of moderate traumatic brain injury using Feeney's weight-dropping method and treated them using rTMS.To help determine the mechanism of action,we measured levels of seve ral impo rtant brain activity-related proteins and their mRNA.On the injured side of the brain,we found that rTMS increased the protein levels and mRNA expression of brain-derived neurotrophic factor,tropomyosin receptor kinase B,N-methyl-D-aspartic acid receptor 1,and phosphorylated cAMP response element binding protein,which are closely associated with the occurrence of long-term potentiation.rTMS also partially reve rsed the loss of synaptophysin after injury and promoted the remodeling of synaptic ultrastructure.These findings suggest that upregulation of synaptic plasticity-related protein expression is the mechanism through which rTMS promotes neurological function recovery after moderate traumatic brain injury. 展开更多

The in vitro fertilization (IVF) success rate in women with poor ovarian response (POR) is very low. Dandelion extract T-1 (DE-T1) is an effective component of the extract from the leaves and stems of Traxacum officinale, which is one of the medicines used in some patients with POR, but its molecular mechanism remains unclear. Methods: Following IVF, ovarian granulosa cells (GCs) of sixty patients were extracted and divided into normal ovarian response (NOR) and POR groups. GCs were cultured in a dose-dependent and time-dependent manner with DE-TI, proliferation of GCs was determined by Cell Counting Kit-8 assay, and mRNA levels of insulin-like growth factor 1 receptor (IGF-1R), luteotropic hormone receptor (LHR), follicle-stimulating hormone receptor (FSHR), LHR, and CYP19A1 (aromatase) were determined by quantitative polymerase chain reaction. Progesterone and estradiol (E2) concentrations were determined by enzyme-linked immunosorbent assay. Results: The cell viability gradually increased with the progressive increase in the DE-T1 concentration. Compared with the control group (without DE-T1), the mRNA expressions of FSHR, LHR, IGF-IR, and CYPIgAI were upregulated after the addition of DE-T l, especially in the 2.5% DE-T 1 group (P 〈 0.01 ). The expression of IGF- 1R was upregulated approximately 25 times (24.97 ± 4.02 times) in the POR group with 2.5% DE-T1. E2 and progesterone levels increased with the increasing DE-T1 concentration. There were highly significant differences in the E2 and progesterone secretion between the NOR and POR groups (P 〈 0.01). Conclusion: DE-TI may promote steroid hormone synthesis by promoting GC proliferation and upregulating GC receptor expression, thereby improving ovarian endocrine function. 展开更多

Paired associative stimulation is a relatively new non-invasive brain stimulation technique that combines transcranial magnetic stimulation and peripheral nerve stimulation. The effects of paired associative stimulation on the excitability of the cerebral cortex can vary according to the time interval between the transcranial magnetic stimulation and peripheral nerve stimulation. We established a model of cerebral ischemia in rats via transient middle cerebral artery occlusion. We administered paired associative stimulation with a frequency of 0.05 Hz 90 times over 4 weeks. We then evaluated spatial learning and memory using the Morris water maze. Changes in the cerebral ultra-structure and synaptic plasticity were assessed via transmission electron microscopy and a 64-channel multi-electrode array. We measured mRNA and protein expression levels of brain-derived neurotrophic factor and N-methyl-D-aspartate receptor 1 in the hippocampus using a real-time polymerase chain reaction and western blot assay. Paired associative stimulation treatment significantly improved learning and memory in rats subjected to cerebral ischemia. The ultra-structures of synapses in the CA1 area of the hippocampus in rats subjected to cerebral ischemia were restored by paired associative stimulation. Long-term potentiation at synapses in the CA3 and CA1 regions of the hippocampus was enhanced as well. The protein and mRNA expression of brain-derived neurotrophic factor and N-methyl-D-aspartate receptor 1 increased after paired associative stimulation treatment. These data indicate that paired associative stimulation can protect cog-nition after cerebral ischemia. The observed effect may be mediated by increases in the mRNA and protein expression of brain-derived neurotrophic factor and N-methyl-D-aspartate receptor 1, and by enhanced synaptic plasticity in the CA1 area of the hippocampus. The animal experiments were approved by the Animal Ethics Committee of Tongji Medical College, Huazhong University of Science & Technology, China(approval No. TJ-A20151102) on July 11, 2015. 展开更多

Paired associative stimulation has been used in stroke patients as an innovative recovery treatment.However,the mechanisms underlying the therapeutic effectiveness of paired associative stimulation on neurological function remain unclear.In this study,rats were randomly divided into middle cerebral occlusion model(MCAO)and paired associated magnetic stimulation(PAMS)groups.The MCAO rat model was produced by middle cerebral artery embolization.The PAMS group received PAMS on days 3 to 20 post MCAO.The MCAO group received sham stimulation,three times every week.Within 18 days after ischemia,rats were subjected to behavioral experiments—the foot-fault test,the balance beam walking test,and the ladder walking test.Balance ability was improved on days 15 and 17,and the footfault rate was less in their affected limb on day 15 in the PAMS group compared with the MCAO group.Western blot assay showed that the expression levels of brain derived neurotrophic factor,glutamate receptor 2/3,postsynaptic density protein 95 and synapsin-1 were significantly increased in the PAMS group compared with the MCAO group in the ipsilateral sensorimotor cortex on day 21.Resting-state functional magnetic resonance imaging revealed that regional brain activities in the sensorimotor cortex were increased in the ipsilateral hemisphere,but decreased in the contralateral hemisphere on day 20.By finite element simulation,the electric field distribution showed a higher intensity,of approximately 0.4 A/m^2,in the ischemic cortex compared with the contralateral cortex in the template.Together,our findings show that PAMS upregulates neuroplasticity-related proteins,increases regional brain activity,and promotes functional recovery in the affected sensorimotor cortex in the rat MCAO model.The experiments were approved by the Institutional Animal Care and Use Committee of Fudan University,China(approval No.201802173 S)on March 3,2018. 展开更多

Recently, more attention has been paid to bio-diversity and complexity. According to the study on M-CSF and its receptor for years, the author suggests that, the multi-level of bio-diversity also appears at the bio-macromolecular level. Probability of bio-diversity is one of the bases for bio-complexity. Cellular sociology and topobiology are important aspects in bio-complexity, and should be developed. If taking Chinese traditional medicine together with the advantage from Reductionism, joining the study on complexity, Chinese scientist would make a chair in the international scientific society. 展开更多
