Understanding The Epigenetic Role Of 8-Oxoguanine And Ogg1 In Non-Small Cell Lung Cancer, Kyrellos Ibrahim
CMC Senior Theses
Oxidative damage to the genome can form 8-oxoguanine (oxoG), a premutagenic lesion suggested to play an epigenetic role in the regulation of various cellular pathways. Alongside oxoG in this regulation is the 8-oxoguanine DNA glycosylase (OGG1), which primarily functions to repair oxoG damage via base excision repair, but is also implicated in recruiting NFκB and impacting gene expression associated with cancer growth. This proposal aims to build genome-wide maps of oxoG occupancy, and indirectly OGG1 localization, in healthy lung cells and in non-small cell lung cancer adenocarcinoma cells in order to identify regulatory regions in the genome at which oxoG …

Using Nmr Spectroscopy And Computational Chemistry To Confirm The Structure Of Novel Antibiotic Nocamycin O, Stephanie Lewis
CMC Senior Theses
In recent years, many medically promising antibiotics have been discovered in nature, especially in insect-microbe symbioses. One of the better-studied examples of this kind of defensive relationship is that of fungus-growing ants and the antibiotic-producing Actinobacteria. These bacteria produce several defensive chemicals with myriad uses, including one antibiotic that inhibits the growth of several bacterial strains, including other Actinobacteria. This antibiotic (known as nocamycin O) is a promising candidate for medicinal use due to its similarities to bacterial RNA polymerase inhibitors tirandamycin and streptolydigin, which inhibit several human pathogens. The determination of the structure of nocamycin O will be an …
