Overexpression of CLN1, CLN2, or ERG13 increases resistance to adriamycin in Saccharomyces cerevisiae.

To elucidate the mechanisms underlying adriamycin resistance, adriamycin resistance-related genes were explored using the budding yeast Saccharomyces cerevisiae as a useful eukaryotic model. The CLN1 and CLN2 genes, encoding G1 cyclin, and the ERG13 gene, encoding 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) synthase, were identified.
