Effect of artemisinin (ART) and artemisinin-loaded polylactic acid nanoparticles (ART-PLA NPs) on serum levels of the tumor marker carcinoembryonic antigen (CEA) in the studied groups. Data are shown as mean ± SEM. Statistically significant differences were observed by one-way ANOVA followed by Tukey’s multiple comparisons test (***p < 0.001, **p < 0.01, *p < 0.05, ns = not significant)
