ROS scavenging and anti-inflammatory effects of D-CeO₂. A Raw 264.7, Colon-26, and NIH 3T3 cell viability after incubation with D-CeO₂ for 24 h and 48 h, respectively. B ROS scavenging activities in H₂O₂ stimulated Raw 264.7 cells were investigated by evaluating the fluorescence of DCFH-DA and flow cytometry. C Protective effect of D-CeO₂ against H₂O₂ induced oxidative damage in Raw 264.7 and Colon-26 cells. D Relative mRNA levels of IL-1β, TNF-α, IL-6, and iNOS in LPS-induced Raw 264.7 cells after indicated treatments. One-way of ANOVA were performed for statistical comparison, *p < 0.05, **p < 0.01, ***p < 0.001
