Figure 4. The MRN complex is activated after PCV2 infection.

Figure 4

(A) Immunofluorescence observation of localization of the MRN complex to the PCV2 replication center. At 24 and 48 h postinfection, Mre11, p-Nbs1, and Rad50 were determined for colocalization with PCV2 ORF1 with their respective antibodies. Nuclei were visualized by DAPI staining. (B) Western blotting of PCV2-infected cells. The PCV2-infected cells were collected at the indicated times postinfection and were analyzed by immunoblotting for the levels of Mre11, p-Nbs1, and Rad50 by use of their respective antibodies. β-actin was acted as the loading control.
