A quantitative mass spectrometry-based approach for assessing the repair of 8-methoxypsoralen-induced DNA interstrand cross-links and monoadducts in mammalian cells.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Interstrand cross-links (ICLs) are highly toxic DNA lesions that block transcription and replication by preventing strand separation. ICL-inducing agents were among the earliest and are still the most widely used forms of chemotherapeutic drugs. Because of the repair of DNA ICLs, the therapeutic efficacy of the DNA cross-linking agents is often reduced by the development of chemoresistance in patients. Thus, it is very important to understand how various DNA ICLs are repaired. Such studies are currently hampered by the lack of an analytical method for monitoring directly the repair of DNA ICLs in cells. Here we report a high-performance liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) method, together with the isotope dilution technique, for assessing the repair of 8-methoxypsoralen (8-MOP)-induced DNA ICLs, as well as monoadducts (MAs), in cultured mammalian cells. We found that, while there were substantial decreases in the levels of ICL and MAs in repair-competent cells 24 h after 8-MOP/UVA treatment, there was little repair of 8-MOP-ICLs and -MAs in xeroderma pigmentosum, complementation group A-deficient human skin fibroblasts and excision repair cross-complementing rodent repair deficiency, complementation group 1-deficient Chinese hamster ovary cells over a 24 h period. This result provided unequivocal evidence supporting the notion that the 8-MOP photoadducts are substrates for nucleotide excision repair in mammalian cells. This is one of the first few reports about the application of LC-MS/MS for assessing the repair of DNA ICLs. The analytical method developed here, when combined with genetic manipulation, will also facilitate the assessment of the roles of other DNA repair pathways in removing these DNA lesions, and the method can also be generally applicable for investigating the repair of other types of DNA ICLs in mammalian cells.
