Comparative Molecular Characterization Of Typical And Exceptional Responders In Glioblastoma, Kristin Wipfler
Comparative Molecular Characterization Of Typical And Exceptional Responders In Glioblastoma, Kristin Wipfler
Theses & Dissertations
Glioblastoma (GBM) is the most common and the deadliest type of primary brain tumor, with a median survival time of only 15 months despite aggressive treatment. Although most patients have an extremely poor prognosis, a small number of patients survive far beyond the median survival time. Investigation of these “exceptional responders” has sparked a great deal of interest and is becoming an important focus in the field of cancer research. To investigate the molecular differences between typical and exceptional responders in GBM, comparative analyses of copy number, methylation, gene expression, miRNA expression, and protein expression data sets from The Cancer …

Wisp1 Is An Overexpressed Driver Of Glioblastoma, Pushan R. Dasgupta
Dissertations & Theses (Open Access)
Despite current multimodal therapies for glioblastoma (GBM) the prognosis remains very grim. There is a tremendous need to identify new genetic drivers which can serve as potential therapeutic targets. In order to find new drivers, we leveraged genomic datasets to conduct a context specific in vivo functional genomic screen of overexpressed and/or amplified genes in GBM. We identified WISP1, a secreted extracellular matrix protein, to be an overexpressed driver in GBM. Overexpression of WISP1 was able to drive tumor growth in various in vivo models. Knockdown of WISP1 with shRNAs resulted in reduced colony formation in vitro and reduced tumor …
A Rapid Colorimetric Peptide Nucleic Acid Loop-Mediated Isothermal Amplification Assay For The Detection Of The Idh1 Mutation In Glioblastoma, Edward J. Raack
A Rapid Colorimetric Peptide Nucleic Acid Loop-Mediated Isothermal Amplification Assay For The Detection Of The Idh1 Mutation In Glioblastoma, Edward J. Raack
All NMU Master's Theses
The IDH1 mutation is an important diagnostic and prognostic biomarker used to characterize glioblastoma (GBM). Patients harboring the IDH1 mutation have improved overall survival following maximal resection. Knowledge of the IDH1 mutation status allows the surgeon to modify the surgical plan; however, no existing molecular test can provide this information intraoperatively. We designed a novel colorimetric peptide nucleic acid loop-mediated isothermal amplification (PNA-LAMP) method that rapidly detects the IDH1 R132H mutation in GBM. PNA-LAMP amplifies target DNA under isothermal conditions with high specificity and speed. The PNA prevents amplification of wild-type IDH1 DNA, while allowing amplification of the R132H variant …
