Figure 5From: Mechanisms of tumor necrosis factor-α-induced interleukin-6 synthesis in glioma cellsEffects of TNF-α on STAT3 phosphorylation. Cultured cells were stimulated with 10 ng/ml TNF-α for the indicated period. Cell extracts were analyzed by Western blotting using antibodies against phospho-specific STAT3 or STAT3. Similar results were obtained with two additional and different cell preparations.Back to article page
