Evaluation Of Drug-Loaded Gold Nanoparticle Cytotoxicity As A Function Of Tumor Tissue Heterogeneity., Hunter Allan Miller
Evaluation Of Drug-Loaded Gold Nanoparticle Cytotoxicity As A Function Of Tumor Tissue Heterogeneity., Hunter Allan Miller
Electronic Theses and Dissertations
The inherent heterogeneity of tumor tissue presents a major challenge to nanoparticle-medicated drug delivery. This heterogeneity spans from the molecular to the cellular (cell types) and to the tissue (vasculature, extra-cellular matrix) scales. Here we employ computational modeling to evaluate therapeutic response as a function of vascular-induced tumor tissue heterogeneity. Using data with three-layered gold nanoparticles loaded with cisplatin, nanotherapy is simulated with different levels of tissue heterogeneity, and the treatment response is measured in terms of tumor regression. The results show that tumor vascular density non-trivially influences the nanoparticle uptake and washout, and the associated tissue response. The drug …

A Clinically Relevant Mouse Model Of Cisplatin-Induced Kidney Injury., Cierra Nichole Sharp
Electronic Theses and Dissertations
Cisplatin is a potent chemotherapeutic used for the treatment of many solid cancers, including testicular, ovarian, and lung cancer. Cisplatin causes many adverse side effects, of which nephrotoxicity leading to acute kidney injury is dose-limiting. Approximately 30% of patients will develop nephrotoxicity with cisplatin, and will either have their next dose of cisplatin lowered, skipped, or be switched to a less nephrotoxic chemotherapeutic altogether. These outcomes are not ideal when trying to treat cancer. Previously, it was believed that patients could recover from cisplatin-induced acute kidney injury with little to no lasting effects, but recent longitudinal studies have shown this …
