Dissertations and Theses (Open Access)

Caspase-8 (CASP8) is one of the most frequently mutated genes in Head and Neck Squamous Carcinomas (HNSCC), and mutations of CASP8 are associated with poor overall survival. The distribution of these mutations in HNSCC suggests that they are likely to be inactivating. Inhibition of CASP8 has been reported to sensitize cancer cells to necroptosis, a unique cell death mechanism. Here, we evaluated how CASP8 regulates necroptosis in HSNCC using cell line models and syngeneic mouse xenografts. In vitro, knockdown of CASP8 rendered HNSCCs susceptible to necroptosis induced by a second mitochondria-derived activator of caspase (SMAC) mimetic, Birinapant, when combined …

Immunotherapy: Therapy Vs. Enhancement, Mariah Daly

Honors Program Theses

The battle against cancer is a long-standing struggle that has resulted in new information and the development of novel medical technologies. Current research aims to figure out a way to reprogram cells and bodily mechanisms to eliminate those cells that are cancerous without destroying healthy cells in the process. Methods which use the body’s own mechanisms, such as immunotherapy, have shown and continue to show potential for specifically targeting cancer cells. Adoptive T cell therapy is one form of immunotherapy that has gained significant attention and focus in the field. Therapies improve conditions up to the normal state of being, …


Augmenting Guadecitabine To Promote Anticancer Immunity In Murine Breast Cancer, Timothy M. Smith Jr. Jan 2020

Augmenting Guadecitabine To Promote Anticancer Immunity In Murine Breast Cancer, Timothy M. Smith Jr.

Theses and Dissertations

In immune-competent individuals, tumor growth occurs due to a failure of the immune system to recognize and destroy malignant cells. Immune surveillance can be curtailed by the presence of immunosuppressive cells such as myeloid-derived suppressor cells (MDSCs) and T-regulatory cells (Tregs) which both serve to dampen antitumor immunity. These studies utilize a metronomic low-dose therapeutic approach to examine the effects of anticancer drugs against murine breast cancer and the effects on the immune cell compartments. The focus of these studies revolve around the drug guadecitabine (guad), a second-generation DNA methyl-transferase inhibitor (DNMTi). DNMTi’s have been shown to dysregulate the methylation …
