Electronic Theses and Dissertations
Mitosis-inhibiting chemotherapeutics (e.g. taxanes) are frequently used to treat multiple cancer types. Recently, there has been much concern about the limited success of these drugs due to resistance and a lack of molecular targets. Thus, there is high demand for new drugs with diverse cellular targets. Targeting the regulators of mitosis is a promising approach. The anaphase promoting complex/cyclosome (APC/C) is an E3 ubiquitin ligase that controls cell cycle progression at multiple points. The interaction of ANAPC2 and ANAPC11, catalytic core subunits, is necessary for APC/C function. An in silico approach was used to identify compounds predicted to prevent assembly …

Longitudinal tracking and accumulation of polymeric nanoparticles in the context of cancer has largely occurred through identification of a fluorescent cargo. In this study, we created a dual extracellular acidic pH targeted polypyrrole-based hollow nanoparticle as a theranostic (maintain both therapeutic and diagnostic capabilities) agent for improved detection and treatment of ovarian cancer. Polypyrrole-hollow nanospheres (PPy-CS) were fabricated through the removal of a silver chloride (AgCl) core, which served as a template, followed by coating with chitosan and further tumor targeted with a pH low insertion peptide, V7. We exploited the NIR-absorbing property of polypyrrole to track both the nanoparticle …

Pseudomonas aeruginosa produces N-(3-oxododecanoyl)-homoserine lactone (C12) as a quorum-sensing molecule that functions to facilitate bacteria-bacteria communication. C12 has also been reported to affect many aspects of human host cell physiology, including evoking cell death in various types of cells. However, the signaling pathway(s) leading to C12-triggerred cell death remains unclear. To clarify cell death signaling induced by C12, we examined mouse embryonic fibroblasts (MEFs) deficient in one or more caspases. Our data indicate that, unlike most apoptotic inducers, C12 evokes a novel form of apoptosis in cells, probably through the direct induction of mitochondrial membrane permeabilization. Importantly, C12 induces apoptosis …
