Rationale Glioblastoma multiforme (GBM) is one of the most aggressive human brain tumors. The prognosis is unfavorable with a median survival of 15 months. GBM aggressive nature is associated with a special phenotype of cancer cells that develops because of the transforming growth factor β (TGF-β). The study was aimed at providing experimental justification in vivo of a possibility to suppress TGF-β production in a tumor via pro-inflammatory modification of cancer cell microenvironment, using CD45+ mononuclear cells of the red bone marrow. Materials and methods The experiment used animals with transplanted C6 glioma. The animals were divided into 4 groups (I) control (N=60); (II) group of rats (N=30) that received granulocyte colony-stimulating factor (G-CSF) to recruit CD45+ bone marrow mononuclear cells into their systemic circulation (G-CSF group); (III) group of rats (N=30) that received pro-inflammatory therapy to trigger systemic inflammatory reaction by injecting bacterial lipopolysaccharides (LPS) andflammatory cytokines TNFα and IL1 in the tumor lesion and adjacent brain matter, remodeling of tumor matrix and higher survival rates for the experimental animals. Conclusions Pro-inflammatory inflammatory modification of cancer cell microenvironment suppresses TGFβ production in a tumor and increases survival rates of the rats with transplanted poorly differentiated malignant brain glioma.Objective Application of Siwei Xiaoliuyin in glioma mice.  https://www.selleckchem.com/products/ABT-263.html  Explore the effect of Siwei Xiaoliuyin on angiogenesis of nude mice glioma and its mechanism. Methods Establish human glioma cell line U87 tumor model. Mice were randomized to the saline group, the conventional dose of Siwei Xiaoliuyin, high dose group of Siwei Xiaoliuyin, TMZ group, combination therapy group, record the tumor volume. Using the method of Weidner counted the microvessel density. ELISA enzyme-linked adsorption method to detect the content of nude mice serum VEGF and ES. The difference was statistically significant (P less then 0.05). Results The tumor volume and MVD of conventional dose group, large dose group, Siwei Xiaoliuyin combined temozolomide group was smaller than the blank group，the difference was statistically significant (P less then 0.05). VEGF levels in three groups of nude mice were lower than the blank group and ES content is higher than blank group, the difference was statistically significant (P less then 0.05). Conclusion Siwei Xiaoliuyin can inhibit glioma angiogenesis. Its mechanism of glioma angiogenesis inhibition may be through regulation VEGF and down-regulation of endostatin expression of vascular endothelial growth factor achieved. Down-regulation of endostatin expression of vascular endothelial growth factor achieved.Glioblastoma multiforme is the most aggressive type of primary brain tumor in humans. Its invasive growth is associated with cluster of differentiation (CD)133 cancer stem cells (CSCs) and CD133- differentiated glioblastoma cells (DGCs) with aggressive phenotype, which are developed under the influence of transforming growth factor (TGF)-β. The present study aimed to compare the proteomes of CD133 CSCs and CD133- DGCs stimulated by TGF-β, as well as the expression levels of the main proteins responsible for activating the signaling pathway of receptor interactions with the extracellular matrix (ECM). The U87MG GBM cell line was used in this study. CSCs were extracted from gliomaspheres through magnetic-activated cell sorting based on the expression of CD133 (CD133); CD133- DCGs served as a control. CD133- DGCs of the U87-MG cell line were treated with 10ng/mL TGF-β1, and cell proliferation and migration were analyzed via real-time quantitative microscopy. High-performance liquid chromatography mass spectrometry was used for proteome analysis. The results revealed 589 proteins with significantly changes in expression among CD133 CSCs compared with those in CD133- DGCs (Ptwofold, while four proteins activated this signaling cascade. TGF-β-stimulation increased the mobility, suppressed the proliferation and transformed the proteome profile of CD133- DGCs. Were identified 13 key proteins that activate the signaling pathway of receptor interaction with the ECM and three proteins activating this signaling pathway in CD133- DGCs which had the same values as those of CD133 CSCs. In conclusion, TGF-β increased the expression of proteins that activate the signaling pathway of receptor interaction with the ECM in CD133- DGCs to the level of those in CD133 CSCs.Twist is a transcription factor involved in the process of epithelial to mesenchymal transition (EMT) of carcinoma cells, and the promotion of invasion of gliomas through the mesenchymal adjusting process. However, its clinical significance in human glioma has not yet to be understood. To delineate the clinical-pathological significance and prognostic value of Twist, the expression of Twist was evaluated by Immunohistochemistry for 187 glioma samples. We found that Twist demonstrated frequent nuclear expression in the glioma samples and its expression levels were associated with tumor grade (P less then 0.001). Furthermore, high Twist expression was correlated with a poor outcome in patients with glioma (P=0.001), particularly with high grade glioma (P=0.026). Interestingly, Twist expression showed positive correlation with microvascular density (MVD) (r=0.145, P=0.048) as well as vasculogenic mimicry (VM) (r=0.273, P less then 0.001) in the tumors. These results suggest that Twist could be a predictor for poor prognosis in glioma patients. Additionally, Twist expression was associated with two major microcirculation patterns endothelial-dependent vessels and VM in glioma, indicating that Twist could be a potential molecular target for anti-glioma therapy.Rationale Glioblastoma multiforme (GBM) is the most aggressive primary glial brain tumor. The prognosis for GBM patients is not favorable, with the median survival time being 15 months. Its treatment resistance is associated with GBM cell population having cancer stem cells (CSCs). Wnt/β-catenin signaling pathway is a strategically important molecular mechanism, providing proliferation of stem cells of all types. This study compares the expression levels of signaling pathway proteins in CD133(+) CSCs and CD133(-) differentiated glioblastoma cells (DGCs). Materials and methods the present study used U-87MG cells of human glioblastoma, the material was tested for mycoplasma contamination. High-performance liquid chromatography (HPLC) mass spectrometry was used for proteome analysis. Biological and molecular functions, signaling pathways and protein-protein interactions were analyzed using free-access databases PubMed, PANTHER, Gene Ontology, Swiss-Prot and KEGG. Protein-protein interactions (PPIs) were analyzed using the STRING database (version 10).
