Role Of The Ang-Tie2 Pathway In The Invasive Recurrence Of Gbm Following Anti-Vegf Therapy, Nahir Cortes Santiago Aug 2014

Role Of The Ang-Tie2 Pathway In The Invasive Recurrence Of Gbm Following Anti-Vegf Therapy, Nahir Cortes Santiago

Dissertations & Theses (Open Access)

Strong pre-clinical and clinical data supporting the effectiveness of bevacizumab, a humanized monoclonal anti-VEGF antibody, for the treatment of gliomas led to its accelerated approval for the treatment of patients with recurrent glioma. However, despite strong anti-tumor effects, upon treatment with bevacizumab, patients will invariably recur with a tumor characterized by enhanced invasiveness and resistance to therapy. This study aims to elucidate the mechanisms leading to this enhanced malignancy with the hope of uncovering new potential therapeutic targets for combined treatment. Using tissue sections from U87-derived glioma bearing mice treated with or without aflibercept (another anti-VEGF antibody) we have gathered …


Discovery And Elucidation Of The Fgfr3-Tacc3 Recurrent Fusion In Glioblastoma, Brittany C. Parker Kerrigan Aug 2014

Discovery And Elucidation Of The Fgfr3-Tacc3 Recurrent Fusion In Glioblastoma, Brittany C. Parker Kerrigan

Dissertations & Theses (Open Access)

Fusion genes occur due to chromosomal instability where two previously separate genes rearrange and fuse together, forming a hybrid gene. The first fusions were reported in leukemias; however, with the advent of more powerful sequencing technologies, fusions have recently been reported in several solid tumors. Using next-generation deep sequencing approaches, we discovered a fusion gene connecting the fibroblast growth factor receptor 3 (FGFR3) gene to the transforming coiled-coil containing protein 3 (TACC3) gene in glioblastoma multiforme. The fusion occurred in 8.3% of patient samples, but not in low grade or normal samples. FGFR3-TACC3 produced an in-frame …


Methodological Development Of A Multi-Parametric Quantitative Imaging Biomarker Framework For Assessing Treatment Response With Mri, Ryan J. Bosca May 2014

Methodological Development Of A Multi-Parametric Quantitative Imaging Biomarker Framework For Assessing Treatment Response With Mri, Ryan J. Bosca

Dissertations & Theses (Open Access)

Quantitative imaging biomarkers (QIBs) are increasingly being incorporated into early phase clinical trials as a means of non-invasively assessing the spatially heterogeneous treatment response to anticancer therapies, particularly as indicators for early response. MR QIBs are derived from the analysis of in vivo imaging data, such as that acquired via dynamic contrast enhanced (DCE), dynamic susceptibility enhanced (DSC), and diffusion tensor imaging (DTI). To date, preclinical and clinical applications of such QIBs have provided strong evidence for potential efficacy, but efforts to create meaningful estimates of localized treatment response using multiple QIBs have been stifled by the need for rigorous …
