Abstract:
Photon-based radiotherapy upregulates Notch signaling in cancer, leading to the acquisition of the stem cell phenotype and induction of invasion/migration, which contributes to the development of resistance to therapy. However, the effect of carbon ion radiotherapy (CIRT) on Notch signaling in glioma and its impact on stemness and migration is not explored yet. Human glioma cell lines (LN229 and U251), stable Notch1 intracellular domain (N1ICD) overexpressing phenotype of LN229 cells, and Notch inhibitor resistant LN229 cells (LN229R) were irradiated with either photon (X-rays) or (carbon ion

Abstract:
Piperlongumine (PL) is recently found to kill cancer cells selectively and effectively via targeting reactive oxygen species (ROS) responses. To further explore the therapeutic effects of PL in cancers, we investigated the role and mechanisms of PL in cancer cell migration. PL effectively inhibited the migration of human glioma (LN229 or U87 MG) cells but not normal astrocytes in the scratch-wound culture model. PL did not alter EdU+-cells and cdc2, cdc25c, or cyclin D1 expression in our model. PL increased ROS (measured by DCFH-DA), reduced glutathione, activated p38 and JNK, increased IκBα,

Abstract:
Integrins play a fundamental role in the migration and invasiveness of glioblastoma (GBM) cells, making them suitable targets for innovative cancer therapy. The aim of this study was to evaluate the effect of the RGD homodimeric disintegrin VLO4, isolated from Vipera lebetina obtusa venom, on the adhesion, spreading, migration, and survival of LBC3, LN18, and LN229 cell lines. This disintegrin, as a potent antagonist for α5β1 integrin, showed pro-adhesive properties for these cell lines, the highest for LN229 and the lowest for LBC3. Glioblastoma cells displayed significant differences in the

Abstract:
Abstract Intrinsic heterogeneous and infiltrative nature of glioblastoma cells to the adjacent normal brain parenchyma are the main obstacles to the treatment of glioblastoma multiforme (GBM). The infiltrative nature of GBM increases following various treatments, which often leads to tumor recurrence. U87 cell line, a commonly used as a GBM cell line till recently, has appeared inappropriate for GBM model. Thus, we established an orthotopic GBM model using another cell line, LN229. Here, we discuss the infiltrative nature of LN229 in the mouse brain and their interaction with adjacent brain mi

Abstract BACKGROUND Somatostatin receptor (SSTR) 2 has been proposed as a target to deliver therapeutic agents to gliomas. The SSTR2 antagonist peptide octofluo was developed to redirect fluorescein-5-isothiocyanate (FITC)-specific adapter chimeric antigen receptor (AdCAR)-T cells towards SSTR2-expressing tumor cells. MATERIAL AND METHODS A tissue microarray of glioblastoma patient samples (N=161) was stained for SSTR2. Octofluo was used as an adapter to direct FITC-specific human CAR-T cells against glioma cells. The SSTR2- glioma cell line LN229 was lentivirally transduced to express SSTR2 a

Background. Glioma is the most common malignant brain tumor and the patients are prone to poor prognosis. Due to limited treatments, new drug exploration has become a general trend. Therefore, the objective of this study is to investigate the effect of the new drugs C18H17NO6and its combination with Scutellarin on glioma cells and the underlying mechanism.Method. U251 and LN229 cells were administrated with C18H17NO6and its combination with Scutellarin. The proliferation ability of glioma cells was determined by cell counting kit-8, plate clone formation assay, and EdU incorporation assay. The

A phytochemical investigation of the steroidal saponins from the rhizomes of Paris polyohylla var. latifolia led to the discovery and characterization of three new spirostanol saponins, papolatiosides A–C (1–3), and nine known compounds (4–12). Their structures were established via extensive spectroscopic data analysis and chemical methods. Interestingly, compounds 1 and 2 possessed a fructosyl in their oligosaccharide moiety, which is rare in natural product and was firstly reported in family Melanthiaceae. The cytotoxicity of these saponins against several human cancer cell lines was evaluat
