The NER proteins XPC and CSB, but not ERCC1, regulate the sensitivity to the novel DNA binder S23906: Implications for recognition and repair of antitumor alkylators

Cells resistant to S23906, a bulky monofunctional agent (left) show increased nucleotide excision repair activity (middle) which is accompanied by increased expression of CSB, XPC, but not ERCC1 (right).
