α-Zearalenol (α-zol) is a Mycotoxin with high affinity for the estrogen receptors (ER), α-Zearalenol is the derivative of zearalenone (ZEN), causes reproductive disorders in animals, due to its xenoestrogenic effects[1-3].
α-Zearalenol (0.001-10 µM; 24-72 hours) induces an increase of cell viability on MCF-7 cells mainly after 72 h of treatment whereas it is slightly cytotoxic on MDA-MB231 cells[4]. α-Zearalenol at low concentrations (10-8-10-9 M;4days) stimulated T47D cell growth[5]. α-Zearalenol(10-10, 10-8 and 10-6 M; 24, 48 and 72 h) was able to increase the protein biosynthesis as well as the lipid metabolism in MCF-7 cells, and, hence, to induce an estrogen positive breast cancer progression[6].
α-Zearalenol (0,25,50 and 75mg/kg once a day for 7 days; i.p.) increased the proportion of malformed sperm, decreased the proportion of live sperm, and decreased acrosome integrity of sperm. α-Zearalenol has a significant harmful effect on the reproductive system of male mice [7].
