摘要：

The most frequent DNA adduct made by the anticancer drug cisplatin, the 1,2-intrastrand d(GpG) crosslink, as well as the minor 1,3-intrastrand d(GpTpG) adduct, were both repaired by an in vitro human excision repair system. Fragments of 27-29 nt containing the platinum damage were excised. The high mobility group (HMG)-domain proteins HMG1 and human mitochondrial transcription factor specifically inhibited repair of the 1,2-intrastrand cross-link by the human excision nuclease. These results suggest that the types and levels of HMG-domain proteins in a given tumor may influence the responsiveness of that cancer to cisplatin chemotherapy and they provide a rational basis for the synthesis of new platinum anticancer drug candidates.
