Cell proliferation in IPEC-J2 cells. Cells were treated with 0 (NC) to 1000 μM NAC and 0 or 100 μM H₂O₂, respectively, for a 2-day period. Cell viability was quantified by CCK-8 assay. Data are expressed as means ± SEM of at least three independent experiments. ^a–eValues with different letters are significantly different (P < 0.05).
