The Effects Of Radiation On Cancer Stem Cells In Glioblastoma And Ovarian Cancer, Aaron Keniston May 2023

The Effects Of Radiation On Cancer Stem Cells In Glioblastoma And Ovarian Cancer, Aaron Keniston

Electronic Theses, Projects, and Dissertations

High grade serous ovarian cancer (HGSOC) and glioblastoma multiforme (GBM) are some of the most aggressive forms of cancer with poor patient survival. Despite successful cancer therapies, these malignancies have high recurrence rates which can be attributed to cancer stem cells (CSC) due to innate tumor initiating properties. In this study, we investigated the response of CSC populations to proton and photon radiation by quantification of core stem cell transcription factors Sox2 and Oct4. This was carried out utilizing a Sox2/Oct4 green fluorescent protein based reporter designated as SORE6-GFP measured by flow cytometry. We hypothesize that proton and photon irradiation …


Hypoxia Regulates Vessel-Modifying Macrophages And Vice Versa In Tumors, Kayla Jo Steinberger Jan 2023

Hypoxia Regulates Vessel-Modifying Macrophages And Vice Versa In Tumors, Kayla Jo Steinberger

Graduate Theses, Dissertations, and Problem Reports

Hypoxia, or low oxygen, is a common feature of solid tumors correlating with poor survival in cancer patients. Growing tumors need a blood supply to deliver oxygen. Tumors attempt to re-acquire oxygen by forming new blood vessels from nearby, pre-existing vessels, a process known as angiogenesis. Past treatments aimed at preventing this process yielded not only disappointing results in the clinic but sometimes worsened the patient’s prognosis making the tumor more hypoxic, emphasizing the urgent need for novel targets. In tumors, angiogenesis is notoriously dysfunctional resulting in leaky, under-perfused blood vessels which cannot adequately deliver oxygen and exacerbates hypoxia. Emerging …
