The effects of fumonisin B1 (FB1) from Fusarium moniliforme on lipid peroxidation and protein and DNA syntheses were studied in monkey kidney cells (Vero cells). FB1 was found to be a potent inducer of malondialdehyde (MDA), one of the secondary products formed during lipid peroxidation. At 0.14 μM (0.1 μg/ml), FB1 induced 0.496 ± 0.1 nmoles of MDA/mg protein, compared to the control level 0.134 ± 0.01 nmoles of MDA/mg protein (P < 0.005). No inhibition of protein or DNA synthesis was observed at this concentration of FB1. Inhibition of protein and DNA syntheses was observed at FB1 concentrations >14 μM (10 μg/ml) with an IC50 of 33 μM for both protein synthesis and DNA synthesis. These results indicate that lipid peroxidation is a very sensitive... |
