Title Base-resolution analysis of cisplatin-DNA adducts at the genome scale
Organisms Homo sapiens; synthetic construct
Experiment type Other
Summary Cisplatin, one of the most widely used anticancer drugs, crosslinks DNA and ultimately induces cell death. However, the genomic pattern of cisplatin-DNA adducts remains unknown, due to the lack of a reliable and sensitive genome-wide method. Here we present “cisplatin-seq” to identify genome-wide cisplatin crosslinking sites at base-resolution. Cisplatin-seq reveals that mitochondrial DNA is a preferred target of cisplatin. For nuclear genome, cisplatin-DNA adducts are enriched within promoters and regions harboring transcription termination sites. While the density of GG dinucleotide determines the initial crosslinking of cisplatin, binding of proteins to the genome largely contributes to the accumulative pattern of cisplatin-DNA adducts.
Overall design Developing a method "Cisplatin-seq" to profile cisplatin-crosslinking site in human genome, using cells treated with cisplatin for 3h, 12h, 24h respectively.
