Transcription profiling of human glioblastoma multiforme tumors taken before dendritic cell vaccination, recurrent tumors after vaccination and control GBM tumors

ABSTRACT: Human Glioblastoma Multiforme tumors taken before dendritic cell vaccination, the recurrent tumors taken after vaccination and control GBM tumors from non vaccinated patients. Experiment Overall Design: Six Glioblastoma Multiforme patients underwent surgery. Their brain tumors were removed and analyzed via microarray. The lysate from the tumors were cultured with the patients' dendritic cells and the DCs were injected back into the patients. The patients GBMs returned and they underwent surgery a second time and those tumors were also analyzed via microarray. Tumors from the first and second GBM surgeries of 5 patients who did not receive DC vaccines are included as controls.

<h4>Background</h4>Small populations of highly tumorigenic stem-like cells (cancer stem cells; CSCs) can exist within, and uniquely regenerate cancers including malignant brain tumors (gliomas). Many aspects of glioma CSCs (GSCs), however, have been characterized in non-physiological settings.<h4>Methods</h4>We found gene expression similarity superiorly defined glioma "stemness", and revealed that GSC similarity increased with lower tumor grade. Using this method, we examined stemness in human ...[more]

Identification of tumor antigens among the HLA peptidomes of Glioblastoma tumors and plasma

Project description:Glioblastoma multiforme (GBM) is the most aggressive brain tumor with poor prognosis to most patients. Immunotherapy of GBM is a potentially beneficial treatment option, whose optimal implementation may depend on familiarity with tumor specific antigens, presented as HLA peptides by the GBM cells. Furthermore, early detection of GBM, such as by a routine blood test, may improve survival, even with the current treatment modalities. This study includes large-scale analyses of the HLA peptidome (immunopeptidome) of the plasma-soluble HLA molecules (sHLA) of 142 plasma samples and the membranal HLA of GBM tumors of 10 tumor samples of the same patients. Tumor samples were fresh-frozen immediately after surgery and plasma samples were collected before, and at multiple visits after surgery. In total, this HLA peptidome analysis involved 52 different HLA allotypes and resulted in the identification of more than 35,000 different HLA peptides. Strong correlations were observed in the signal intensities and in the repertoires of identified peptides between the tumors and plasma-soluble HLA peptidomes of the same patients; yet, low correlations were observed between these HLA peptidomes and the tumors’ proteomes. HLA peptides derived from Cancer/Testis Antigens (CTAs) were selected based on their presence among the HLA peptidomes of the patients and absence of expression of their source genes from any healthy and essential human tissues, except from immune-privileged sites. Additionally, peptides were selected as potential biomarkers if their levels in the plasma-sHLA peptidome were significantly reduced after the removal of tumor mass. The CTAs identified among the analyzed HLA peptidomes provide new opportunities for personalized immunotherapy and for early diagnosis of GBM.

Comprehensive transcriptomic profiling of glioblastoma patient-derived primary tumor cell lines using bulk RNA-sequencing

Project description:Glioblastoma multiforme (GBM) is a highly aggressive primary brain cancer with significant transcriptomic heterogeneity among patients. Our study aims to contribute to the field of personalized medicine for GBM patients by providing comprehensive transcriptomic profiles of GBM patients (N = 45) who underwent concurrent chemoradiotherapy with temozolomide at Seoul National University Hospital. Additionally, we include transcriptomic profiles of normal brain tissue obtained from GBM patients. This dataset may add depth to existing knowledge by uncovering distinct transcriptomic signatures related to aggressiveness in GBM, and may inform future research on the molecular mechanisms underlying transcriptomic features of GBM and personalized treatment strategies.

Unique RNA Expression Patterns in Serum Exosomes from Patients with Glioblastoma Multiforme

Project description:Comparative expression analysis of RNA isolated from microvesicles from serum from glioblastoma multiforme (GBM) patients and normal healthy individuals. Blood samples from 9 patients diagnosed with de-novo primary GBM were collected immediately prior to surgery. Blood from 7 normal healthy controls was collected from volunteers recruited at the MGH blood bank. From each sample, RNA was isolated from microvesicles isolated from 1 mL of serum, and the RNA was linearly amplified and labeled with Cy3. The amplified and labeled RNA was hybridized to 16 individual Agilent Arrays.

Multi-omics profiling of paired primary and recurrent glioblastoma patient tissues

Project description:Background Despite maximal therapy with surgery, chemotherapy and radiotherapy, glioblastoma multiforme (GBM) patients have a median survival of only 15 months. Almost all patients inevitably experience symptomatic tumor recurrence. A hallmark of this tumor type is the large heterogeneity between patients and within tumors itself which relate to failure of standardized tumor treatment. In this study, tissue samples of paired primary and recurrent GBM tumors were investigated to identify individual factors related to tumor progression. Methods Paired primary and recurrent GBM tumor tissues from 8 patients were investigated with a multi-omics approach using transcriptomics, proteomics and phosphoproteomics. Results In the studied patient cohort, large variations between and within patients are observed for all omics analyses. A few pathways affected at the different omics levels partly overlapped if patients are analyzed at the individual level, such as synaptogenesis (containing the SNARE complex) and cholesterol metabolism. Phosphoproteomics revealed increased STMN1(S38) phosphorylation that relates to ERBB4 signaling. A pathway tool has been developed to visualize and compare the different omics datasets per patient and showed potential therapeutic drugs, such as abobotulinumtoxina and afatinib, that target these affected pathways. Afatinib targeting ERBB4 signaling is currently in clinical trials for GBM. Conclusions Large variation on all omics levels exist between and within GBM patients. Therefore, it will be rather unlikely to find a drug treatment that would fit all patients. Instead a multi-omics approach can be used to identify affected pathways on the individual patient level and select potential treatment options.
