Suppressive Effect on Lipopolysaccharide-Induced Proinflammatory Mediators by Citrus aurantium L. in Macrophage RAW 264.7 Cells via NF- B Signal Pathway

Figure 4

Suppressive effect of CME on the production of LPS-induced proinflammatory cytokines in RAW 264.7 cells. The RAW 264.7 cells were pretreated with CME (5, 10, 20, and 50  g/mL) for 1 hour, and then stimulated with LPS (1  g/mL). After 6 hours, the total mRNA was isolated, and the mRNA levels of (a) TNF- and (b) IL-6 were examined by RT-PCR. * indicates an increase in mRNA expression relative to the control ( ), ** indicates a decrease in mRNA expression relative to the LPS group ( ).
