Enrichment for DNA mismatch repair-deficient cells during treatment with cisplatin

Abstract excerpt

In addition to playing a role in tumorigenesis, loss of DNA mismatch repair results in low-level intrinsic resistance to cisplatin and carboplatin. We used a mismatch repair-deficient (clone B) and -proficient (clone B/rev) pair of Chinese hamster ovary sublines to determine the ability of cisplatin to enrich for repair-deficient cells during growth in vitro and in vivo. Clone B cells were 1.8-fold resistant to...
