Resveratrol inhibits reproductive toxicity induced by deoxynivalenol
The aim of this in vitro study was to examine the release of progesterone by porcine ovarian granulosa cells (GCs) after exposure to toxic concentrations of deoxynivalenol (DON), resveratrol (RSV), and their combination (DON with RSV). Ovarian granulosa cells were incubated without (control) or with treatments of natural substances at various doses for 24 h: RSV (10, 30 and 50 μg/mL) / DON (2000, 3000 and 5000 ng/mL), and their combination (10 μg/mL of RSV with 2000 ng/mL of DON; 30 μg/mL of RSV with 3000 ng/mL of DON; 50 μg/mL of RSV with 5000 ng/mL of DON). Progesterone was determined by radioimmunoassay (RIA). Progesterone release was significantly (P < 0.05) stimulated by RSV at the doses 50 μg/mL but not at 30 and 10 μg/mL and by DON treatment at all used doses (2000, 3000 and 5000 ng/mL). RSV in combination with DON stimulated significantly (P < 0.05) the progesterone release by GCs at the highest doses (50 μg/mL of RSV with 5000 ng/mL of DON). On the other hand, the stimulatory effect of RSV in combination with DON was significantly (P < 0.05) lower in comparison with alone DON effect. In conclusion, our results indicate, (1) the dose-depended stimulatory effects of RSV, DON and combination of RSV with DON on release of steroid hormone progesterone and (2) reduction of the stimulatory effect of DON by RSV. Our in vitro results suggest that reproductive toxicity of animals induced by a mycotoxin - deoxynivalenol can be inhibited by a protective natural substance – resveratrol.
