Porphyrin Overdrive In Cancer: Unraveling The Mechanisms And Therapeutic Potential, Pravin D. Meshram

USF Tampa Graduate Theses and Dissertations

The increased understanding of cancer cell metabolism has shown options for novel treatment strategies. This thesis looks at the role of heme metabolism, specifically "porphyrin overdrive," in cancer progression and treatment. Cancer cells are hypermetabolic and rely on heme synthesis. When treated with δ-aminolevulinic acid (ALA), they abnormally accumulate heme intermediates. This metabolic weakness presents an opportunity to exploit heme synthesis in targeted cancer therapy. In this study, we suggest a "Bait and Kill" technique that uses exogenous ALA to induce protoporphyrin IX (PpIX) buildup in cancer cells, making them more susceptible to oxidative stress. We investigate the possibility of …

Black Holes In Time: The Effect Of Grid Radiation On The Tumor Immune Microenvironment, Rebecca A. Bekker

USF Tampa Graduate Theses and Dissertations

Tumor-immune interactions shape a developing tumor and its tumor immune microenvironment (TIME) resulting in either well-infiltrated, immunologically inflamed ‘hot’ tumor beds, or ‘cold’ immune deserts with low levels of infiltration. The pre-treatment immune state of the TIME is associated with treatment outcome; immunologically hot tumors generally exhibit better responses to radio- and immunotherapy than cold tumors. However, radiotherapy is known to induce opposing immunological consequences, resulting in both immunostimulatory and inhibitory responses. In fact, it is thought that the radiation induced tumoricidal immune response is curtailed by subsequent applications of radiation. Thus, I hypothesize that spatially fractionated radiotherapy (SFRT), administered …
