Induction of cytokine mRNA and protein expression in SC19-infected J774A.1 macrophages with or without fisetin treatment. J774A.1 macrophages were treated with 32 μg/ml fisetin in the absence (negative control) or presence of SC19 for 5 h. (A) The mRNA levels of IL-1β and TNF-α were determined by qRT-PCR. (B) The cytokine protein levels in the supernatants were determined by ELISAs. The bars represented the SEMs, on the basis of three independent experiments. Statistically significant differences are indicated. P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001.
