Abstract: Amygdalin is one of many nitrilosides, which are natural cyanide-containing substances abundant in the seeds of apricots, almond, peaches, apples, and other rosaceous plants. It is a controversial anti-tumor natural product that has been used as an alternative cancer drug for many years. On the other hand, one of the most widely distributed mycotoxin contaminating food and animal feed is deoxynivalenol (DON). Deoxynivalenol has adverse effects on humans, animals, and crops that result in illnesses. The aim of the in vitro study was to investigated the effect of natural substance amygdalin at the selected doses (1, 10, 100, 1000, 10 000 µg/mL) in combination with deoxynivalenol (1000 ng/mL) on secretion of steroid hormones (progesterone and estradiol) by ovarian granulosa cells (GCs) from cyclic pigs. Our results showed that the releasing of progesterone and estradiol by ovarian granulosa cells was affected by amygdalin plus DON addition. The secretion of progesterone by ovarian GCs was significantly (P≤0.05) affected by administration of both compounds in all experimental groups. Similarly, estradiol releasing by GCs was significantly (P≤0.05) increased in experimental groups with amygdalin (10, 100 and 10 000 µg/mL) plus DON (1000 ng/mL) addition. Amygdalin treatment combined with DON caused increase of steroid hormones release by ovarian granulosa cells. Our findings suggest possible involvement of these natural substances (amygdalin and deoxynivalenol) in the regulation process of steroidogenesis. In conclusion, results from this experiment contribute to knowledge about interaction between two different natural compounds and their positive or negative interferences with ovarian functions.
