1 Tumor necrosis factor is cytotoxic to human fibroblasts in the presence of exogenous arachidonic acid. Arachidonic Acid tumor necrosis factor Homo sapiens
2 However, TNF had a cytotoxic effect upon the growth of FS-4 cells in combination with arachidonic acid. Arachidonic Acid tumor necrosis factor Homo sapiens
3 Arachidonic acid inhibited the TNF-induced cell growth in a dose-dependent manner: it reversed the TNF-stimulated growth to the control level at a concentration of 10 microM and was cytotoxic to TNF-treated FS-4 cells at higher concentrations. Arachidonic Acid tumor necrosis factor Homo sapiens
4 Arachidonic acid inhibited the TNF-induced cell growth in a dose-dependent manner: it reversed the TNF-stimulated growth to the control level at a concentration of 10 microM and was cytotoxic to TNF-treated FS-4 cells at higher concentrations. Arachidonic Acid tumor necrosis factor Homo sapiens
5 Arachidonic acid inhibited the TNF-induced cell growth in a dose-dependent manner: it reversed the TNF-stimulated growth to the control level at a concentration of 10 microM and was cytotoxic to TNF-treated FS-4 cells at higher concentrations. Arachidonic Acid tumor necrosis factor Homo sapiens
6 Indomethacin, a cyclooxygenase inhibitor, decreased the cytotoxic effect that TNF exerted in the presence of arachidonic acid. Arachidonic Acid tumor necrosis factor Homo sapiens
7 These results suggest that TNF becomes cytotoxic to FS-4 cells when arachidonic acid present in the culture medium is converted to prostaglandins. Arachidonic Acid tumor necrosis factor Homo sapiens
