Expression data from high grade astrocytoma surgical samples

(Submitter supplied) Survival in the majority of high grade astrocytoma (HGA) patients is very poor, with only a rare population of long-term survivors. A better understanding of the biological factors associated with long-term survival in HGA would aid development of more effective therapy and prognostication. We used microarray gene expression profiling of 26 patient surgical samples with known clinical outcomes to discover novel prognostic markers.

High grade astrocytoma patient survival: brain tumor

Analysis of surgical brain tumors from high grade astrocytoma (HGA) patients with known clinical outcomes. Increased expression of immune function-related genes was positively correlated with longer survival. Results provide insight into molecular profiles associated with long-term survival in HGA.

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

(Submitter supplied) 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). more...

Expression data from ependymoma surgical samples

(Submitter supplied) Ependymoma, the 3rd most common brain tumor in children, recurs in approximately 50% of patients. There is currently no robust marker that predicts for recurrence, which is a significant clinical problem We used global gene expression profiling of 19 patient surgical samples obtained at initial diagnosis and with known clinical outcomes to discover novel prognostic markers.

Differential gene expression in astrocytic tumours

(Submitter supplied) This study aims at investigating differential gene expression in human astrocytic tumours of grades I, II, III and IV. A total of 65 tumours were assessed using the Affymetrix U133A GeneChip. The study aims not only at discovering the main expression differences between astrocytic tumours of distinct histological grades but also wishes to correlate these findings with the known histopathological hallmarks of astrocytoma progression. more...

Human Glioblastoma

(Submitter supplied) Summary: Astrocytomas can be categorized as either low grade or high grade (glioblastoma). Low grade astrocytomas are not generally aggressive tumors whereas glioblastomas are and in turn have a high mortality rate. The purpose of this experiment is to identify genetic differences between the two types. Hypothesis: There will be a difference in RNA expression between high grade and low grade tumors. more...

Gene expression analysis of Merkel Cell Carcinoma

(Submitter supplied) Merkel cell carcinoma (MCC) is a polyomavirus-associated skin cancer that is frequently lethal and lacks established prognostic biomarkers. The purpose of this study was to use gene expression analysis to identify biomarkers that may improve prognostic accuracy and provide insight into MCC biology.

Gene expression profiling of canine osteosarcoma reveals genes associated with short and long survival times

(Submitter supplied) Osteosarcoma (OS) accounts for approximately 80% of all malignant bone tumors in the dog. Tumors are highly metastatic and long-term survival is poor. This study aims to investigate the prognosis associated gene expression profile in primary canine OS. Canine specific cDNA microarray representing 20,313 genes was used to analyze expression profiles in a panel of thirty-two primary osteosarcoma to identify genes associated with survival. more...

caArray_hanas-00078: Distinctive molecular profiles of high-grade and low-grade gliomas based on oligonucleotide microarray analysis

(Submitter supplied) Astrocytomas are heterogeneous intracranial glial neoplasms ranging from the highly aggressive malignant glioblastoma multiforme (GBM) to the indolent, low-grade pilocytic astrocytoma. We have investigated whether DNA microarrays can identify gene expression differences between high-grade and low-grade glial tumors. We compared the transcriptional profile of 45 astrocytic tumors including 21 GBMs and 19 pilocytic astrocytomas using oligonucleotide-based microarrays. more...

miRNA expression profiling of primary melanoma tumors (cohort II)

(Submitter supplied) We performed global microRNA expression profiling of a cohort of primary melanoma patient samples linked to a well-annotated clinical database. The goal of this study was to identify microRNA that are associated to or correlated with various clinical parameters and patient outcomes. Candidate microRNA were identified for building prognostic models and functional testing.

Expression data from human brain tumors and human normal brain

(Submitter supplied) The characteristics of immune cells infiltrating pediatric brain tumors is largely unexplored. A better understanding of these characteristics will provide a foundation for development of immunotherapy for pediatric brain tumors. Gene expression profiles were used to identify immune marker gene that are differentially expressed between various brain tumor types.
