DPC’s can lead to cell death if it is not repaired due to its potential to interfere with cellular processes such as DNA replication and transcription because it causes a bulky distortion in the DNA double helix. Various chemical agents, such as 1,2,3,4-Diepoxybutane (DEB), are known to induce DPC’s because of their alkylating functions. When uncontrollably created in cells, DPC’s have a harmful effect, but they can have a therapeutic function if they are specifically induced in cells and controlled. Thus, with its potential lethalness to cells, DPC’s have been studied as a possible cancer treatment by trying to target its production in tumor cells and observing its biological activity. To better understand, DPC’s, this project focused on the creation of DPC’s using 8-oxoguanine glycosylase (OGG1) and the OG oligonucleotide duplex (OG). Specific focus was placed on the induction and purification of the OGG1 protein and cross-linking it to OG.en-USDepartment of Biochemistry, Molecular Biology and BiophysicsCollege of Biological SciencesDepartment of PharmacologyAcademic Health CenterPresentation
