Repurposing Clinically Relevant Metabolic Inhibitor Drugs, Difluoromethylornithine (Dfmo) And Orlistat, For Gammaherpesvirus Replication, Lay Paw
Honors Projects
Viruses, including herpesviruses, contribute up to 15% of all human cancers. Murine gammaherpesvirus-68 (MHV-68), a pathogen commonly found in mice, is studied due to its shared homology with several human herpesviruses. Studies done in the Delgado lab via metabolomics analysis show MHV-68 infected cells increase host cell metabolism. Clinically relevant metabolic inhibitor drugs, ɑ-Difluoromethylornithine (DFMO) and Orlistat, respectively block polyamine and lipid production demonstrated a reduction in MHV-68 viral production. Repurposing clinically relevant drugs through the exploration of a different target shows great promise in reducing oncogenic viral titer.
Discovering The Role Of Repeat Sequences In Regulation Of The Phaz Gene In Streptomyces Sp. Sfb5a, Harrison Senter, Stephen Baron
Discovering The Role Of Repeat Sequences In Regulation Of The Phaz Gene In Streptomyces Sp. Sfb5a, Harrison Senter, Stephen Baron
Honors Projects
Streptomyces sp. SFB5A is an actinomycete (filamentous bacterium) that degrades PHB using an extracellular PHB depolymerase. PHB depolymerase synthesis is induced by growth on PHB and repressed by glucose (or other preferred carbon sources)2, which suggests that there is transcriptional regulation of its corresponding gene, phaZ. Binding sites are suspected to be the repeat sequences found in the phaZ gene. There are 3 different sets of primers that can be made in order to emphasize specific functional repeats while disrupting the functionality of others. The goal of the project is to transform Streptomyces sp. 5A with constructs …
Optimization Of The Split-Spinach Aptamer For Monitoring Contiguous Rna Nanoparticle Assembly, Jack M. O'Hara
Optimization Of The Split-Spinach Aptamer For Monitoring Contiguous Rna Nanoparticle Assembly, Jack M. O'Hara
Honors Projects
The emerging field of RNA nanotechnology takes advantage of the RNA’s ability to self-assemble into exquisite structures. As nanoparticle design continues to advance and move into increasingly complex biological systems, tools to monitor their assembly and location will be of great importance. Here, a split-aptamer system is used to monitor assembly of a six-membered nanoring based on fluorescence feedback of a fluorophore. First, the split-aptamer is designed into two of the six pieces of the ring. Through mutation and deletion, we optimize the fluorescence feedback established when a six membered nanoparticle assembles, compared to partial assembly. We demonstrate that with …
