TNFα Mediated IL-6 Secretion Is Regulated by JAK/STAT Pathway but Not by MEK Phosphorylation and AKT Phosphorylation in U266 Multiple Myeloma Cells

Figure 2

Regulation of IL-6 release by TNFα in vitro. After serum starvation, U266 and IM9 multiple myeloma cells were treated with or without 1 ng/mL TNFα for indicated times. Cell supernatants from each experimental sample were harvested for ELISA and IL-6 concentrations were determined at different time points with TNFα treatment. Relative fold changes compared to TNFα nontreated samples as a control were shown in graph. Bars represent the mean ± SEM from three independent experiments.
