Met inhibits
the LPS-induced inflammatory stress in RAW 264.7 macrophages.
RAW 264.7 cells were pretreated with 10 mM Met for 12 h prior to stimulation
with 100 μg/mL LPS for 3 h. The gene expression of (A) IL-6,
(B) TNF-α, and (C) IFN-β was analyzed by RT-qPCR. (D–F)
Effects of Met on LPS-stimulated IL-6, TNF-α, and IFN-β
secretion from RAW 264.7 cells were analyzed by ELISA. Cells were
cultured for 12 h with Met (10 mM) and then treated with LPS (100
ng/mL) for 12 h. Data represent the mean ± SD of three independent
experiments, each performed in five samples. Comparisons among means
used t-tests (*p < 0.05, **p < 0.01, ***p < 0.001).
