Analysis Of The Repair Of Topoisomerase Ii Dna Damage, Eric Goldstein
The Pegasus Review: UCF Undergraduate Research Journal
A large number of anti-cancer chemotherapeutics target DNA topoisomerases. Etoposide is a specific topoisomerase II poison that causes reversible double strand DNA breaks. This project analyses the repair of DNA damage induced by etoposide, a common anti-cancer chemotherapeutic. Through the comparison of two known DNA repair pathways, anti-cancer chemotherapy may become more cytotoxic. Double strand DNA break repair is mediated by either non-homologous end joining (NHEJ) or homologous recombination (HR). NHEJ repairs through direct ligation of a double stranded break, whereas HR utilizes a homologous template to recover the wild type sequence. Reporter cassettes involving the expression of green fluorescent …
