GSH-C4 treatment abrogates the production and expression of pro-inflammatory cytokines in C2C12 myotubes and 3T3-L1 adipocytes. (A) C2C12 cells were differentiated for 4 days. Subsequently, 10 mM GSH-C4 was added to the myotubes for 12 or 24 hrs. IL-1β, IL-6, and TNF-α production in culture supernatants were detected using Luminex Assay (Bio-Rad). Data are expressed as means ± S.D. (n = 4; **p < 0.001). (B) Total RNA was isolated and relative mRNA levels of IL-1β, IL-6, and TNF-α were analyzed by RT-qPCR. mRNA levels were normalized to RPL. Data are expressed as means ± S.D. (n = 6; **p < 0.001). (C) 3T3-L1 cells were differentiated for 8 days. Subsequently, 10 mM GSH-C4 was added to the adipocytes for 12 or 24 hrs. IL-1β, IL-6, and TNF-α production in culture supernatants were detected using Luminex Assay (Bio-Rad). Data are expressed as means ± S.D. (n = 3; **p < 0.001). (D) Total RNA was isolated and relative mRNA levels of IL-1β, IL-6, and TNF-α were analyzed by RT-qPCR. mRNA levels were normalized to RPL. Data are expressed as means ± S.D. (n = 4; **p < 0.001). All the images reported in the figures are representative of at least three experiments that gave similar results.
