WebWe found that codon 285, a mutational hotspot at a non-CpG site in bladder cancer, is the preferential binding site for N-OH-4-ABP. We also found that C5 cytosine methylation greatly enhanced N-OH-4-ABP binding at CpG sites, and that two mutational hotspots at CpG sites, codons 175 and 248, became preferential binding sites for N-OH-4-ABP only ...
