Fig. 2From: E2F2 directly regulates the STAT1 and PI3K/AKT/NF-κB pathways to exacerbate the inflammatory phenotype in rheumatoid arthritis synovial fibroblasts and mouse embryonic fibroblastsE2F2 is required for production of inflammatory factors in MEFs. MEFs were treated with different concentrations of lipopolysaccharide (LPS) for 12 h. Expression and dose-dependent effects of interleukin (IL)-1α (a), IL-1β (b), and tumor necrosis factor (TNF)-α (c) were detected by qRT-PCR. **P < 0.01, ***P < 0.001, versus vehicle control. Dose-dependent effects of secreted IL-1α (d), IL-1β (e), and TNF-α (f) were detected by ELISA. **P < 0.01, ***P < 0.001, versus vehicle control. IL-1α, IL-1β, and TNF-α in serum of E2f2−/− and wild-type (WT) mice were measured by ELISA (g). **P < 0.01, ***P < 0.001, versus WTBack to article page
