Effects of licochalcone A (LA) on the mRNA levels of cytokines, chemokines, and inflammatory mediators in the lungs. Gene expression levels were determined by real-time RT-PCR using RNA extracted from the lung tissues of normal (N) and OVA-stimulated (OVA) mice, with or without licochalcone A (LA5-10) treatment. Fold-changes in expression were measured relative to the β-actin expression (internal control). Three independent experiments were analyzed, and data were presented as mean ± SEM. * P < 0.05 compared to the OVA control group. ** P < 0.01 compared to the OVA control group.
