PGCs are more sensitive to DNA double-strand breaks than somatic cells. (A) Cell viability curves after 24 h treatment with increasing concentrations of etoposide (ETP; x-axis shows log 10 [ETP]). PGC viability dropped sharply even at low ETP doses, whereas CEF cells were more tolerant (viability data are mean ± SD of triplicates). (B) Apoptosis detection in PGCs treated with low-dose ETP. The proportion of Annexin V + /PI + cells (late apoptosis) was significantly elevated even at 0.03 µM ETP. (C) Western blot analysis of γ-H 2 AX protein in PGCs treated with varying ETP concentrations (left panel; β-actin as loading control). The bar graph (right) shows the ratio of γ-H 2 AX to β-actin band intensity, with a marked increase at 3 µM ETP (p-values are indicated in the figure). (D) Quantification of γ-H 2 AX foci per cell in THP-1 cells, male PGCs, and female PGCs after exposure to X-ray doses of 0, 2, 4, 6, and 8 Gy. After 48 h recovery, γ-H 2 AX foci increased significantly with higher radiation in THP-1, male PGCs, and female PGCs. Female PGC data points are red squares; male PGCs are blue squares; THP-1 are black circles. (E) Cell-cycle distribution of male vs. female PGCs after DNA damage. PGCs were irradiated (2, 4, 6 Gy), cultured 48 h, and analyzed by flow cytometry for cell-cycle phase (propidium iodide staining). Stacked bars show the percentage of cells in G 0 G 1 , S, and G 2 /M phases in untreated vs. irradiated cells. After damage, female PGCs predominantly arrested in G 2 /M (increased G 2 fraction), whereas male PGCs accumulated in S phase. Statistical significance by one-way ANOVA (p-values are indicated in the figure).

The interaction between Neu1 and ZBP1 regulates apoptosis and sialic acid levels in BCoV-infected MDBK cells. A , B Schematic representation and validation of stable MDBK Neu1kd and MDBK ZBP1kd cell lines. C Apoptosis analysis of WT, MDBK Neu1kd , and MDBK ZBP1kd cells following BCoV infection via Annexin V-PE/7-AAD flow cytometry. D , E Viral titers determined via the Reed–Muench method ( D ) and relative BCoV mRNA expression levels ( E ). F Immunofluorescence localization of Neu1 (red) and ZBP1 (green) in WT, MDBK Neu1kd , and MDBK ZBP1kd cells. Nuclei were stained with DAPI (blue), and merged signals (yellow) indicate colocalization. G Cellular sialic acid levels significantly decreased in both MDBK Neu1kd and MDBK ZBP1kd cells. H Immunofluorescence analysis further demonstrated that Neu1 or ZBP1 knockdown markedly reduced the fluorescence signal intensity during BCoV infection. The data are presented as the means ± SDs ( n = 3). The quantification of fluorescence intensity is shown in Additional file . Statistical significance: * P < 0.05, ** P < 0.01, *** P < 0.001.
