Figure 4From: Adenosine A2B receptor-mediated leukemia inhibitory factor release from astrocytes protects cortical neurons against excitotoxicity Effect of signaling pathway inhibitors on survival of cultured astrocytes. Primary cortical astrocytes were treated without or with different signaling pathway inhibitors used in this study (U 0126, 5 to 10 μM; SB 203580, 10 to 20 μM; BAY 11–7082, 10 to 20 μM; Ro 31–8220, 250 to 500nM; KT 5720, 250 to 500nM; SP 600125, 10 to 20 μM) for 24 hours and cell survival assessed by a colorimetric MTT assay. The optical densities were measured at 570 nm, with a 630 nm and blank correction. Data are normalized to percent of control (vehicle) and presented as Mean ± S.E.M of three independent experiments. P < 0.05, when compared to control.Back to article page
