DNA double-strand break repair functions defend against parvovirus infection.

By T J Tauer, M H Schneiderman, J K Vishwanatha and S L Rhode

Abstract

We measured parvovirus replication and sensitivity to X-ray damage in nine CHO cell lines representing a variety of DNA repair deficiencies. We found that parvovirus replication efficiency increases with radiosensitivity. Parvovirus replication is disrupted at an early stage of infection in DNA repair-proficient cells, before conversion of the single-stranded viral DNA genome into the double-stranded replicative form. Thus, status of the DNA repair machinery inversely correlates with parvovirus replication and is proportional to the host's ability to repair X-ray-induced damage
