Figure Lengend Snippet: (A and B) Immunofluorescence staining of γ-H2AX (red) and H2AX (green) in HSV-1-infected HeLa cells (A) or PRV-infected 3D4/21 cells (B) (MOI = 1). Scale bars: 10 μm. (C and D) Comet assay assessing DNA damage in HeLa cells infected with HSV-1 (MOI = 1). Data are mean ± SEM; n = 40 cells/group. ** P < 0.01, *** P < 0.001. (E and F) Comet assay assessing DNA damage in 3D4/21 cells infected with PRV (MOI = 1) at the indicated time points. Data are mean ± SEM; n = 40 cells/group. ** P < 0.01, *** P < 0.001. (G and H) Immunoblotting analysis of DDR markers (p-ATM, p-ATR, p-Chk1, p- Chk2, γ-H2AX) and viral ICP4/EP0 in HSV-1-infected HeLa cells (G) or PRV-QXX-infected 3D4/21 cells (H) (MOI = 1). (I) Viral titers in HSV-1-infected HeLa cells (MOI = 1) treated with berzosertib (50 nM) or vehicle. Data are mean ± SEM; n = 3. * P < 0.05, ** P < 0.01, *** P < 0.001 (J) Survival curves of HSV-1-infected mice (1 × 10⁶ PFU/mouse) treated with berzosertib (20 mg/kg) or vehicle (n = 12/group), *** P < 0.001.
