Z-DNA-forming sequences generate large-scale deletions in mammalian cells.

Abstract excerpt

Spontaneous chromosomal breakages frequently occur at genomic hot spots in the absence of DNA damage and can result in translocation-related human disease. Chromosomal breakpoints are often mapped near purine-pyrimidine Z-DNA-forming sequences in human tumors. However, it is not known whether Z-DNA plays a role in the generation of these chromosomal breakages. Here, we show that Z-DNA-forming sequences induce...
