Cell viability and expression of LPS-induced pro-inflammatory cytokines under conditions with sweet potato extracts: (A) Cell viability at 24 h of incubation after the addition of the sweet potato extracts at concentrations of 1 µg/mL, 10 µg/mL, and 100 µg/mL; (B) Relative production level of IL-6 at 24 h after LPS stimulation with/without each sweet potato extracts; (C) Relative expression of pro-inflammatory genes (IL-6, Tnf, iNOS(Nos2)) at 24 h after LPS stimulation with/without sweet potato tuber extracts: (A,B) mean ± SEM, one-way ANOVA with Dunnett’s post-hoc test (vs +LPS), **: p < 0.01, ****: p < 0.0001; (C) mean ± SEM, Student’s t-test, *: p < 0.05, ****: p < 0.0001: LPS, lipopolysaccharide; Ext, extract.
