Inflammation and lymphocyte infiltration are associated with shorter survival in patients with high-grade glioma

Project description:Glioma represents a serious health burden in terms of morbidity and mortality. The prognostic significance of the lymphoid and myeloid infiltrates in glioma is not clearly determined. Moreover, the characterization of different leukocyte subsets in the tumor microenvironment relies mainly on immunohistochemistry observations, and data about their association with prognosis are contradictory. Here, we performed acomprehensive study of both the tumor-infiltrating and circulating immune compartments of patients with high-grade glioma. We identified prognostic tumor and peripheral immune signatures, which associate increased inflammation, immune infiltration and activation with shorter overall survival in high-grade glioma patients. Importantly, we confirmed our observations by flow cytometry analysis and validated the tumor-signature using the TCGA dataset. In addition, both tumor genotype and grade associated with the degree of glioma immune infiltration. Unlike in the majority of cancers, lymphocyte infiltration at the tumor site is anegative prognostic factor in glioma, suggesting the ambivalent pro-tumorigenic role of immune responses in glioma.

Here, we performed acomprehensive study of both the tumor-infiltrating and circulating immune compartments of patients with high-grade glioma. Nineteen tumor biopsies and 30 PBMC samples were analyzed by RNA sequencing. Validation was performed on The Cancer Genome Atlas (TCGA) RNA sequencing data from glioma and on additional 39 tumor biopsies analyzed by flow cytometry. We identified prognostic tumor and peripheral immune signatures, which associate increased inflammation, immune infiltration and activation with shorter overall survival in high-grade glioma patients. Importantly, we confirmed our observations by flow cytometry analysis and validated the tumor-signature using the TCGA dataset.

CircGLIS3 promotes high-grade glioma invasion via modulating Ezrin phosphorylation

Project description:High-grade glioma is highly aggressive and malignant, resistant to combined therapies and easy to relapse. A better understanding of circRNA biological function in high-grade glioma might contribute to the therapeutic efficacy. Here, a circRNA merely up-regulated in high-grade glioma, circGLIS3 (hsa_circ_0002874, originating from exon 2 of GLIS3), was validated by microarray and qRT-PCR. Functional experiments uncovered that up-regulation of circGLIS3 promoted glioma cell migration and invasion, and showed aggressive characteristics in tumor-bearing mice. Fluorescence in situ hybridization, RNA pull-down, RNA immunoprecipitation and immunohistochemical staining showed that circGLIS3 could promoted Ezrin T567 phosphorylation. Further investigation showed that circGLIS3 could be excreted by glioma through exosomes and induced endothelial cells angiogenesis. This study indicates that circGLIS3 is up-regulated in high-grade glioma and contributes to the invasion and angiogenesis of glioma via promoting Ezrin T567 phosphorylation.

A model of molecular characteristics to classify WHO Grade III glioma patients

Project description:Combing WHO classification and molecular characteristics to analysis gliomas more and more important. But Grade III glioma samples have a big difference within the group had not been reported as far as we know. In this study, we proposed a model to evaluate diagnosis and prognosis of Grade III glioma patients, and two independent datasets indicated that the model has a good predictive ability. Therefore, this strategy provides a new method to assist diagnosis and treatment of Grade III glioma patients.

A multi-component view of the glioma transcriptome identifies unique immune infiltration patterns in primary glioblastomas and patients with inferior prognosis.

Project description:Patients diagnosed with glioblastomas continue to have a dismal prognosis, highlighting the need for a better characterization of these tumors in order to identify more efficient therapies. In this study, we generated genome-wide expression data from normal brain and glioma samples, representing major glioma subtypes, using exon-level microarrays (n=70). A multi-component approach was used to characterize molecular pathways and tumor infiltrate, with particular focus on the poor prognosis primary glioblastomas (pGBM). Two independent, publically available datasets were used for validation of survival data. Grade II glioma and secondary GBM were enriched in cytotoxic lymphocytes, while pGBM exhibited a heterogeneous cell-related immune infiltrate with high infiltration of monocytic cells. Infiltration by cells of monocytic origin predicted poorer prognosis, regardless of the tumor subtype. High TSPYL2 expression was found to be associated with a poor prognosis in pGBM and to correlate with genes involved in tumor invasion. The multi-component transcriptome phenotypes of pGBM introduced in this study add insights into the main pathways associated with aggressiveness, and identified infiltration by cells of monocytic origin as a universal prognostic marker for all glioma subtypes.

Single-Cell Transcriptome Analysis of Lineage Diversity and Microenvironment in High-Grade Glioma

Project description:Despite extensive molecular characterization, we lack a comprehensive picture of lineage identity, differentiation, and microenvironmental composition in high-grade gliomas (HGGs). We sampled the cellular milieu of HGGs with massively-parallel single-cell RNA-Seq. While HGG cells can resemble glia or even immature neurons and form branched lineage structures, mesenchymal transformation results in unstructured populations. Glioma cells in a subset of mesenchymal tumors lose their neural lineage identity, express inflammatory genes, and co-exist with marked myeloid infiltration, implying a molecular interaction between glioma and immune cells. Finally, we found that myeloid cells can resemble microglia, macrophages, or a hybrid state, and enrichment of these cells is predictive of poor survival.
