Effects of AC and dexamethasone on the growth of RAW 264.7 cells. (A) Cells were incubated in a complete medium with the indicated concentrations of AC and dexamethasone for 24 h, and cell viability was measured by the LDH and MTT assay. (B) Macrophages were treated with AC and dexamethasone (10, 20, 40, and 80 μM) and exposed to LPS (100 ng/mL) for 24 h. Cellular viability was measured using the LDH and MTT assay. Each value represents the mean ± SD of three independent experiments. ^∗P < 0.05, ^∗∗P < 0.01 compared with the control group; ^#P < 0.05, ^##P < 0.01 compared with the LPS-treated group.
