Cisplatin is a chemotherapy drug that kills cancer cells by damaging their DNA. In human cells, this damage is repaired primarily by nucleotide excision repair. While cisplatin is generally effective, many cancers exhibit initial or acquired resistance to it. Here, we studied cisplatin resistance in a defined cell line system. We conducted a comprehensive genomic characterization of the cisplatin-sensitive A2780 ovarian cancer cell line compared to A2780cis, its resistant derivative. The resistant cells acquired less damage, but had similar repair kinetics. Genome-wide mapping of nucleotide excision repair showed a shift in the resistant cells from global genome towards transcription-coupled repair. By mapping gene expression changes following cisplatin treatment, we identified 56 upregulated genes that have higher basal expression in the resistant cell line, suggesting they are primed for a cisplatin response. More than half of these genes are novel to cisplatin- or damage-response. Six out of seven primed genes tested were upregulated in response to cisplatin in additional cell lines, making them attractive candidates for future investigation. These novel candidates for cisplatin resistance could prove to be important prognostic markers or targets for tailored combined therapy in the future.
