WebJan 7, 2024 · Fig. 2. DPCs are composed of DNA, protein, and their cross-linked bonds, which can be targeted by different repair pathways. NER and HR are nuclease-dependent pathways that can directly cleave DNA molecules. The chemical bond between TOP1/TOP2 and DNA can be directly hydrolyzed by TDP1 and TDP2/ZNF451. WebCytotoxic synergy was also seen between HU + ara-C themselves. The effect of the combined antimetabolites on the level and persistence of DDP-induced DNA interstrand cross-links was assessed by DNA alkaline elution. These were measured as an indicator of DDP-DNA adduct formation and removal. java 补0http://photobiology.info/Smith_Shetlar.html java 表示什么
