Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with dismal prognosis. The only curative option for patients is surgery, but over 80% of patients are not surgical candidates. Unfortunately, PDAC is resistant to the three remaining options. PDAC is characterized by a profoundly hypoxic and immunosuppressive stroma, which contributes to its therapeutic recalcitrance. Alpha-smooth muscle actin+ (αSMA+) cancer-associated fibroblasts (CAFs) are the most abundant stromal component, as well as mediators of stromal deposition. The hypoxia-inducible factors (HIF1 and HIF2) coordinate responses to hypoxia, yet, despite their known association to poor patient outcomes, their functions within the PDAC tumor microenvironment (TME) …

The knowledge surrounding cancers of the central nervous system remains poorly developed, in particular with regard to the immune component. The works contained in this thesis look at craniopharyngioma, glioblastoma, and several forms of brain metastasis. While some attention is given to the tumor cells themselves, as well as the patient setting which these studies model, the immune component of disease progression and treatment plays a strong role in each and is the primary focus of the works contained.
Craniopharyngioma is a relatively rare tumor in adults. Although histologically benign, it can be locally aggressive and may require additional therapeutic …

Uncontrolled proliferation of cancer cells necessitates rewiring of metabolic pathways to meet biosynthetic and bioenergetic demands of proliferation and fortify redox homeostasis. An increasing body of literature suggests that mitochondrial metabolism (tricarboxylic acid cycle (TCA) and oxidative phosphorylation) is imperative for cancer cell growth and proliferation. The scope of the works presented in this dissertation is to explore the importance of mitochondrial metabolism, and primarily the TCA cycle—the anabolic factory of cancer cells and leverage it as a targetable vulnerability in cancer. Cancer cells consume anabolic nutrients that are used to generate biosynthetic precursors in the TCA cycle. Continuous efflux …
