Dr. Yalowich’s lab focuses on the mechanisms of action and resistance to DNA topoisomerase II (topo II)-targeted agents, such as the anticancer agent etoposide (VP-16). Recent work has characterized alternative RNA processing of topo IIα pre-mRNA that results in decreased expression of full-length topo II in acquired resistance to VP-16. Strategies to circumvent resistance involve CRISPR/Cas9 gene editing to restore proper RNA splicing function in resistant cells. A second project involves the role of micro-RNAs as determinants of drug resistance. Finally, the use of nutritional antioxidants (such as vitamin C) is under investigation as a strategy to prevent cancer-causing effects of topo II-targeted agents, which can arise in patients years after therapy is complete.
