Current systemic treatment options for patients with ACCs are far from being satisfactory. DNA damage/repair mechanisms, which involve e.g. ATM/ATR-signalling or RRM1/RRM2 encoded ribonucleotide reductase (RNR) activation commonly contribute to drug resistance. Moreover, also the regulation of RRM2b, the p53-induced alternative to RRM2, is of unclear importance for ACC. Upon extensive drug screening, including a large panel of classical chemotherapies (doxorubicin, etoposide, ...
