In advanced and metastatic stages of colorectal cancer (CRC), reduced sensitivity to conventional strategies is still a major obstacle to successful treatments. Decorin is an important regulator in the development and progression of various cancers. To examine if CRC patients have altered decorin levels, expression of decorin and its target genes, Met and vascular endothelial growth factor A (VEGFA) were analyzed in their tumors. Compared to normal tissues, decorin expression was reduced in CRC patients' tumors, while, there were increased Met and VEGFA levels...

INTRODUCTION: Most common source of stem cell graft for both autologous and allogenic haematopoietic transplants are peripheral blood haematopoietic progenitor stem cells. Adequate collection of the CD34+ cells and safety of the allogenic donor during the leukapheresis are of prime importance to an apheresis physician. Our retrospective analysis is a comparison between of two platforms namely, COBE Spectra and Amicus, for CD34+ mononuclear cell collection. MATERIAL AND METHOD: The study included the data of GSCF (Granulocyte-Colony-Stimulating Factor) mobilized allogenic PBSC collections at our centre from January 2015 to June 2016...

Granulocyte colony-stimulating factor (G-CSF) is routinely used in the clinic to mobilize hematopoietic stem progenitor cells (HSPC) into the patient's blood for collection and subsequent transplantation. However a significant proportion of patients who have previously received chemotherapy or radiotherapy and requiring autologous HSPC transplantation, cannot mobilize the minimal threshold of mobilized HSPC to achieve rapid and successful hematopoietic reconstitution. Although several alternatives to the G-CSF regime have been tested, few are in use in the clinic...

Alcoholic hepatitis manifests as a clinical syndrome characterized by recent jaundice and liver function deterioration in an actively drinking patient. The principal cause of alcoholic hepatitis is alcoholic steatohepatitis defined histologically by the coexistence of steatosis, hepatocyte ballooning and satellitosis. While non-severe alcoholic hepatitis usually responds to alcohol abstinence, severe alcoholic hepatitis, identified by Maddrey scoring ≥ 32, has a bad prognosis and is traditionally treated by a 28-day course of prednisone therapy...

The role of autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF) in the development of secondary pulmonary alveolar proteinosis (PAP) in patients exposed to occupational and environmental dust remains unclear. Herein, we describe two cases of secondary PAP who had GM-CSF antibodies and absence of STAT5 phosphorylation index, suggestive of a potential relationship between the appearance of GM-CSF antibodies and environmental dust exposure. However, whether the presence of GM-CSF antibodies is a part of the pathological process or represents an epiphenomenon is currently unknown...

The antimicrobial function of neutrophils, which is dependent on opsonin receptors, deteriorates in severe acute pancreatitis (SAP). Granulocyte colony-stimulating factor (G-CSF) putatively enhanced levels of the opsonin receptors CD11b and CD32/16 in healthy human subjects, and provided protection against infection in animal models of SAP. A statistically convincing study of the effect of G-CSF on CD32/16 expression in an SAP model is lacking. We used a mouse model of SAP to investigate the association between G-CSF administration and CD32/16 levels on neutrophils and bacterial translocation...

Pulmonary alveolar proteinosis is a rare lung disease in which lipoproteinaceous material accumulates within the alveoli, interfering with gas exchange. The disease is classified into congenital, secondary, and acquired. The congenital form includes inborn errors of surfactant metabolism, lysinuric protein intolerance and mutations in the components of granulocyte-macrophage colony-stimulating factor receptor. The main symptoms are non-specific. The radiologic appearance of pulmonary alveolar proteinosis is bilateral, symmetric and perihilar airspace consolidation...

Pathogenic Yersinia enterocolitica is widely distributed in China where the primary bio-serotypes are 3/O: 3 and 2/O: 9. Recently, the distribution of 2/O: 9 strains are being gradually replaced by 3/O: 3 strains where presently 3/O: 3 strains are the major pathogenic Y. enterocolitica in China. To identify the growth conditions and cytokines induced by Y. enterocolitica and providing some clues for this shift, we performed competitive growth in vitro and in vivo for these two bio-serotype strains; and we also compared the cytokines induced by them in infected BALB/C mice...

Purpose: Although local oncolytic viral therapy (OVT) may enhance tumor lysis, antigen release, and adaptive immune responses, systemic antitumor responses post-therapy are limited. Adoptive immunotherapy with autologous dendritic cells (DC) and cytokine-induced killer cells (DC-CIK) synergizes with systemic therapies. We hypothesized that OVT with Herpes Simplex Virus-granulocyte macrophage-colony-stimulating factor (HSV-GM-CSF) would induce adaptive T cell responses that could be expanded systemically with sequential DC-CIK therapy...

The duration of post-sepsis long-term immune suppression is poorly understood. Here, we focused on the role of monocytes (MO) as the pivotal cells for long-term regulation of post-sepsis milieu. Lost ability of MO to adapt is seen in several acute conditions, but it is unclear for how long MO aberrancy post-sepsis can persist. Interestingly, the positive feedback loop sustaining secretion of macrophage-colony stimulation factor (M-CSF) can persist even after resolution of sepsis and significantly alters performance of MO...

Bleomycin pulmonary toxicity (BPT) is a well-described complication of bleomycin-containing regimens. Previous data on risk factors and the impact of BPT on survival in Hodgkin lymphoma (HL) were conflicting. We reviewed 253 HL patients treated with adriamycin, bleomycin, vinblastine, dacarbazine (ABVD) at the Princess Margaret Hospital from 1999 to 2009 to examine the incidence and risk factors for BPT, and the effect of BPT on survival. BPT was defined by pulmonary symptoms, bilateral interstitial infiltrates on computed tomography, and the absence of infection...

Objective To investigate the roles of tumor-associated macrophages (TAMs) and epithelial growth factor receptor (EGFR)/β-catenin signaling pathway in sorafenib resistance of hepatocellular carcinoma cells. Methods Macrophages were isolated from peripheral blood mononuclear cells (PBMCs) and cultured in the presence of colony-stimulating factor (M-CSF) to obtain TAMs. Phenotypes of TAMs were identified. The level of epithelial growth factor (EGF) secreted by TAMs was detected by ELISA. CCK-8 assay was performed to verify the effects of EGF on HepG2 and SMMC7721 cell proliferation...

BACKGROUND AIMS: Myelodysplastic syndromes (MDS) are a group of clonal stem cell disorders affecting the normal hematopoietic differentiation process and leading to abnormal maturation and differentiation of all blood cell lineages. Treatment options are limited, and there is an unmet medical need for effective therapies for patients with severe cytopenias. METHODS: We demonstrate that multipotent adult progenitor cells (MAPC) improve the function of hematopoietic progenitors derived from human MDS bone marrow (BM) by significantly increasing the frequency of primitive progenitors as well as the number of myeloid colonies...

In cervical cancer, the epidermal growth factor receptor (EGFR) is overexpressed in 70-90% of the cases and has been associated with poor prognosis. EGFR-based therapy is currently being explored in cervical cancer. We investigated which EGFR ligand is primarily expressed in cervical cancer and which cell type functions as the major source of this ligand. We hypothesized that macrophages are the main source of EGFR ligands and that a paracrine loop between tumor cells and macrophages is responsible for ligand expression...

The fms-like tyrosine kinase 3 (Flt3) is a cell surface receptor that is expressed by various hematopoietic progenitor cells (HPC) and Flt3-activating mutations are commonly present in acute myeloid and lymphoid leukemias. These findings underscore the importance of Flt3 to steady-state and malignant hematopoiesis. In this study, the expression of Flt3 protein and Flt3 mRNA by single cells within the hematopoietic stem cell (HSC) and HPC bone marrow compartments of C57/BL6 mice was investigated using flow cytometry and the quantitative reverse transcription polymerase chain reaction...

Oncolytic virotherapy is an emerging immunotherapeutic modality for cancer treatment. Oncolytic viruses with genetic modifications can further enhance the oncolytic effects on tumor cells and stimulate antitumor immunity. The oncolytic vaccinia viruses JX-594-GFP+/hGM-CSF (JX-GFP) and TG6002 are genetically modified by secreting granulocyte-macrophage colony-stimulating factor (GM-CSF) or transforming 5-fluorocytosine (5-FC) into 5-fluorouracil (5-FU). We compared their properties to kill tumor cells and induce an immunogenic type of cell death in a human melanoma cell model using SK29-MEL melanoma cells...

Bone marrow (BM) aspirates, mobilized peripheral blood (PB) and umbilical cord blood (UCB) have developed as graft sources of hematopoietic stem and progenitor cells (HSPC) for stem cell transplantation and other cellular therapeutics. Individualized techniques are necessary to enhance graft HSPC yields and cell quality from each graft source. BM aspirates yield adequate CD34+cells but can result in relative delays in engraftment. Granulocyte-colony stimulating factor (G-CSF) primed bone marrow HSPC may facilitate faster engraftment while minimizing graft-versus-host disease (GVHD) in certain patient subsets...

Increasing evidence shows that exposure to an enriched environment (EE) is neuroprotective in adult and neonatal animal models of brain ischemia. However, the mechanisms underlying this effect remain unclear. The aim of the current study was to investigate whether post-weaning EE would be effective in preventing functional deficits and brain damage by affecting markers of synaptic plasticity in a neonatal rat model of hypoxia-ischemia (HI). We also examined the possibility that granulocyte-colony stimulating factor (G-CSF), a growth factor with known neuroprotective effects in a variety of experimental brain injury models, combined with EE stimulation could enhance the potential beneficial effect of EE...
