Genome instability is a hallmark of cancer cells. It has been proposed that at early stages of the cancer process, genomic instability is caused by oncogene-induced replication stress, a poorly-understood process characterized with the accumulation of stalled replication forks and gammaH2AX on chromatin. Understanding the origin of chronic replication stress represents a major challenge in cancer biology. We have previously shown that depletion of DNA Topoisomerase 1 or the splicing factor ASF/SF2 in mammalian cells interferes with replication fork progression, activating the DNA damage response and inducing chromosome breaks (Tuduri et al., 2009). Since DNA damage and replication fork stalling are relieved by RNaseH1, an attractive hypothe...
