Abstract
Glioblastoma is the most deadly and common primary tumor of the central nervous system. Heterogeneity in the disease causes complications from diagnosis to treatment. It has long been suggested that a stem cell and/or progenitor population may be the origin of this disease and provide the underlying heterogeneity. However, which population precisely is the cell of origin, or whether there is only one cell of origin, has remained elusive. Previous studies have shown that, with proper combinations of oncogene expression and tumor suppressor loss, three cell types have the potential to transform into glioma-neural stem cells (NSC), oligodendrocyte precursor cells (OPC), and astrocytes. In a newly published article in Cancer Research, Verma and colleagues make a convincing argument through elegant animal work that an intermediate progenitor cell population, primitive OPCs, has higher tumorigenic potential than the NSCs or OPCs. This study helps rectify the controversy around which cell populations are the most sensitive to transformation in gliomagenesis. See related article by Verma et al., p. 890.

Abstract
Immune checkpoint blockade (ICB) has revolutionized cancer treatment, yet quality of life and continuation of therapy can be constrained by immune-related adverse events (irAEs). Limited understanding of irAE mechanisms hampers development of approaches to mitigate their damage. To address this, we examined whether mice gained sensitivity to anti-CTLA-4 (αCTLA-4)-mediated toxicity upon disruption of gut homeostatic immunity. We found αCTLA-4 drove increased inflammation and colonic tissue damage in mice with genetic predisposition to intestinal inflammation, acute gastrointestinal infection, transplantation with a dysbiotic fecal microbiome, or dextran sodium sulfate administration. We identified an immune signature of αCTLA-4-mediated irAEs, including colonic neutrophil accumulation and systemic interleukin-6 (IL-6) release. IL-6 blockade combined with antibiotic treatment reduced intestinal damage and improved αCTLA-4 therapeutic efficacy in inflammation-prone mice. Intestinal immune signatures were validated in biopsies from patients with ICB colitis. Our work provides new preclinical models of αCTLA-4 intestinal irAEs, mechanistic insights into irAE development, and potential approaches to enhance ICB efficacy while mitigating irAEs.

Abstract
Glioblastoma (GBM) is a high-grade, aggressive brain tumor with dismal median survival time of 15 months. Chromosome 6q (Ch6q) is a hotspot of genomic alterations, which is commonly deleted or hyper-methylated in GBM. Two neighboring genes in this region, QKI and PRKN have been appointed as tumor suppressors in GBM. While a genetically modified mouse model (GEMM) of GBM has been successfully generated with Qk deletion in the central nervous system (CNS), in vivo genetic evidence supporting the tumor suppressor function of Prkn has not been established. In the present study, we generated a mouse model with Prkn-null allele and conditional Trp53 and Pten deletions in the neural stem cells (NSCs) and compared the tumorigenicity of this model to our previous GBM model with Qk deletion within the same system. We find that Qk but not Prkn is the potent tumor suppressor in the frequently altered Ch6q region in GBM.

Abstract
Novel therapeutic strategies targeting glioblastoma (GBM) often fail in the clinic, partly because preclinical models in which hypotheses are being tested do not recapitulate human disease. To address this challenge, we took advantage of our previously developed spontaneous Qk/Trp53/Pten (QPP) triple-knockout model of human GBM, comparing the immune microenvironment of QPP mice with that of patient-derived tumors to determine whether this model provides opportunity for gaining insights into tumor physiopathology and preclinical evaluation of therapeutic agents. Immune profiling analyses and single-cell sequencing of implanted and spontaneous tumors from QPP mice and from patients with glioma revealed intratumoral immune components that were predominantly myeloid cells (e.g., monocytes, macrophages, and microglia), with minor populations of T, B, and NK cells. When comparing spontaneous and implanted mouse samples, we found more neutrophils and T and NK cells in the implanted model. Neutrophils and T and NK cells were increased in abundance in samples derived from human high-grade glioma compared with those derived from low-grade glioma. Overall, our data demonstrate that our implanted and spontaneous QPP models recapitulate the immunosuppressive myeloid-dominant nature of the tumor microenvironment of human gliomas. Our model provides a suitable tool for investigating the complex immune compartment of gliomas.

Abstract
Abstract
Glioblastomas multiforme (GBMs) are the most lethal tumors of the brain. Tumoral mesenchymal transformation is a hallmark of GBMs associated with alterations in cellular morphology and dynamic organization. However, little is known about the mechanisms that control this pathological process. Here, we report a comprehensive spatiotemporal study integrating novel intra-tumoral histopathological structures, ‘oncostreams’, with tumor dynamic properties, microenvironment assets and spatial molecular features. Cellular analyses of genetic engineered mouse models of glioma identified that oncostreams are heterogenous structures formed by elongated and aligned neoplastic cells enriched in non-neoplastic cells such as ACTA2+ mesenchymal like cells and CD68+ tumor associated microglia/macrophages (TAM). Deep learning analysis of H&E glioma histological samples from mouse and human gliomas identified that oncostream density correlates with tumor aggressiveness. To determine whether oncostreams fascicles are characterized by a specific gene expression profile, we performed transcriptomic analysis using laser capture microdissection coupled to RNA-sequencing. We found that oncostreams are defined by a transcriptomic signature enriched in mesenchymal genes. Network analyses identified that COL1A1 is a critical gene that regulates oncostream organization and function. Correspondingly, human and mouse high-grade gliomas with high oncostream densities showed prominent alignment of collagen fibers along these fascicles and higher COL1A1 expression compared to low-grade gliomas. To evaluate the functional role of COL1A1 in oncostream formation we generated a COL1A1-deficient GEMM of glioma. We observed that COL1A1 inhibition decreased oncostream formation, impaired tumor cell proliferation and remodeled the tumor microenvironment by diminishing CD68+ TAM cells, CD31+ endothelial vascular proliferation and ACTA2+ perivascular mesenchymal cells, thus increasing animal survival. Further studies, using time lapse confocal imaging in ex vivo glioma explants, and intravital imaging in vivo demonstrated that oncostreams are organized collective dynamic structures present at the tumor core and the invasive tumor border. Oncostreams dynamics increased the intra-tumoral spread of cells within the tumor and foster glioma aggressiveness through collective invasion of the normal brain parenchyma. The analysis of glioma invasion in COL1A1 knockdown tumors exhibited a reduction in collective migration patterns, strongly supporting its importance in tumor progression. We propose that oncostreams represent a novel pathological marker of potential value for diagnosis and COL1A1 depletion within oncostreams is a promising approach and reprogram mesenchymal transformation to reduce the tumor malignancy.

Abstract
Abstract
Immunotherapies such as anti-CTLA-4 immune checkpoint blockade (ICB) have revolutionized cancer treatment, yet quality of life and continuation of therapy can be constrained by off-target tissue damage or immune-related adverse events (irAEs). At present, there is limited understanding of irAE mechanisms, hampering development of approaches to mitigate their damage. We addressed this problem by generating animal models of intestinal irAE. Our results show that disruption of homeostatic immunity by genetic predisposition to intestinal inflammation or acute gastrointestinal infection sensitizes mice to anti-CTLA-4-mediated intestinal toxicity. Inflammation-prone mice treated with anti-CTLA-4 showed neutrophil accumulation, systemic interleukin-6 (IL-6) release, and dysbiosis. Significantly, IL-6 blockade combined with antibiotic treatment improved anti-CTLA-4 therapeutic efficacy and reduced intestinal irAEs. Immune signatures were validated in biopsies from patients who developed colitis during ICB, supporting the utility of our models. This study provides new pre-clinical models, mechanistic insight into irAEs, and potential approaches to enhance ICB efficacy while mitigating irAEs.

Abstract
Glioblastoma multiforme (GBM), the most aggressive brain cancer, recurs because glioblastoma stem cells (GSCs) are resistant to all standard therapies. We showed that GSCs, but not normal astrocytes, are sensitive to lysis by healthy allogeneic natural killer (NK) cells in vitro. Mass cytometry and single-cell RNA sequencing of primary tumor samples revealed that GBM tumor-infiltrating NK cells acquired an altered phenotype associated with impaired lytic function relative to matched peripheral blood NK cells from patients with GBM or healthy donors. We attributed this immune evasion tactic to direct cell-to-cell contact between GSCs and NK cells via αv integrin-mediated TGF-β activation. Treatment of GSC-engrafted mice with allogeneic NK cells in combination with inhibitors of integrin or TGF-β signaling or with TGFBR2 gene-edited allogeneic NK cells prevented GSC-induced NK cell dysfunction and tumor growth. These findings reveal an important mechanism of NK cell immune evasion by GSCs and suggest the αv integrin/TGF-β axis as a potentially useful therapeutic target in GBM.

Abstract
BACKGROUND High-grade gliomas are aggressive and immunosuppressive brain tumors. Molecular mechanisms that regulate the inhibitory immune tumor microenvironment (TME) and glioma progression remain poorly understood. Fyn tyrosine kinase is a downstream target of the oncogenic receptor tyrosine kinase pathway and is overexpressed in human gliomas. Fyn's role in vivo in glioma growth remains unknown. We investigated whether Fyn regulates glioma initiation, growth and invasion. METHODS We evaluated the role of Fyn using genetically engineered mouse glioma models (GEMMs). We also generated Fyn knockdown stem cells to induce gliomas in immune-competent and immune-deficient mice (nonobese diabetic severe combined immunodeficient gamma mice [NSG], CD8-/-, CD4-/-). We analyzed molecular mechanism by RNA sequencing and bioinformatics analysis. Flow cytometry was used to characterize immune cellular infiltrates in the Fyn knockdown glioma TME. RESULTS We demonstrate that Fyn knockdown in diverse immune-competent GEMMs of glioma reduced tumor progression and significantly increased survival. Gene ontology (GO) analysis of differentially expressed genes in wild-type versus Fyn knockdown gliomas showed enrichment of GOs related to immune reactivity. However, in NSG and CD8-/- and CD4-/- immune-deficient mice, Fyn knockdown gliomas failed to show differences in survival. These data suggest that the expression of Fyn in glioma cells reduces antiglioma immune activation. Examination of glioma immune infiltrates by flow cytometry displayed reduction in the amount and activity of immune suppressive myeloid derived cells in the Fyn glioma TME. CONCLUSIONS Gliomas employ Fyn mediated mechanisms to enhance immune suppression and promote tumor progression. We propose that Fyn inhibition within glioma cells could improve the efficacy of antiglioma immunotherapies.

Abstract
Glioma cells grow in two phenotypic forms, as adherent monolayers and as free floating “neurospheres/tumorspheres”, using specific media supplements. Whether each phenotype is irreversible remains unknown. Herein we show that both states are reversible using patient derived glioblastoma cell cultures (i.e., HF2303, IN859, MGG8, IN2045). Both phenotypic states differ in proliferation rate, invasion, migration, chemotaxis and chemosensitivity. We used microarrays to characterize gene expression across the patient derived glioblastoma cell cultures, to find specific inhibitors of the sphere population. Traditional chemotherapeutics (i.e., doxorubicin or paclitaxel) inhibit rapidly dividing adherent cells; it has been more challenging to inhibit the growth of the sphere phenotype. PRKG1, known to induce apoptosis when activated, is increased in all patient derived glioblastoma spheres. Stimulation of PRKG1 activity preferentially reduced cell viability in the sphere phenotype. Computational network and gene ontology analysis identified novel potential target genes linked to the PRKG1 expression node.

Abstract
Purpose: One likely cause of treatment failure in glioblastoma is the persistence of glioma stem-like cells (GSLCs) which are highly resistant to therapies currently employed. We found that CXCL12 has highest expression in glioma cells derived from neural progenitor cells (NPC). The development and molecular signature of NPC-derived glioblastomas were analyzed and the therapeutic effect of blocking CXCL12 was tested.Experimental Design: Tumors were induced by injecting DNA into the lateral ventricle of neonatal mice, using the Sleeping Beauty transposase method. Histology and expression of GSLC markers were analyzed during disease progression. Survival upon treatment with pharmacologic (plerixafor) or genetic inhibition of CXCR4 was analyzed. Primary neurospheres were generated and analyzed for proliferation, apoptosis, and expression of proteins regulating survival and cell-cycle progression.Results: Tumors induced from NPCs display histologic features of human glioblastoma and express markers of GSLC. In vivo, inhibiting the CXCL12/CXCR4 signaling axis results in increased survival of tumor-bearing animals. In vitro, CXCR4 blockade induces apoptosis and inhibits cell-cycle progression, downregulates molecules regulating survival and proliferation, and also blocks the hypoxic induction of HIF-1α and CXCL12. Exogenous administration of CXCL12 rescues the drug-induced decrease in proliferation.Conclusions: This study demonstrates that the CXCL12/CXCR4 axis operates in glioblastoma cells under hypoxic stress via an autocrine-positive feedback mechanism, which promotes survival and cell-cycle progression. Our study brings new mechanistic insight and encourages further exploration of the use of drugs blocking CXCL12 as adjuvant agents to target hypoxia-induced glioblastoma progression, prevent resistance to treatment, and recurrence of the disease.
