Figure 5: Concentration-dependent effects of RVE on LPS-induced STAT6 and pSTAT6 expression in RAW 264.7 cells.Lysates were prepared from control or stimulated cells treated for 24 h with LPS (1μg/ml) alone or in combination with increasing concentrations (0.5- 5.0 mg/ml) of RVE. The experiment was repeated three times with similar results.
