Fig. 6. Effects of TQCPS on LPS-induced IL-6 and TNF-α secretion, and mRNA expression. (a and b) RAW 264.7 cells were treated with LPS with or without different concentrations of TQCPS for 24 h. The levels of IL-6 and TNF-α were analyzed by ELISA. (c and d) RAW 264.7 cells were treated with LPS with or without different concentrations of TQCPS for 12 h. The mRNA levels of IL-6 and TNF-α were determined by RT-PCR analysis. LPS (0.5 μg mL−1) was used as a positive control. The data are presented as the mean ± SD (n = 3). *p < 0.05, **p < 0.01 compared with the control group.
