Abstract The effect of hypoxia on the release of tumor necrosis factor-α (TNF-α) in transformed rat retinal ganglion cells (RGCs) and the effect of agmatine on the hypoxia-induced production of TNF-α in RGCs were evaluated. RGCs were cultured under hypoxic conditions with 5% oxygen, with or without 100 μM agmatine. The expression levels of TNF-α and its receptor-1 (TNF-R1) were investigated by Western blot analysis. After 6 hours of hypoxia, we noted an increase in TNF-α production in RGCs. Agmatine significantly reduced TNF-α level after 12 hours of hypoxic treatment. The expression of TNF-R1 was not affected by the hypoxia or… More >
