Zearalenone is able to occupy the active site of ERs in a strikingly similar manner as E2. Zearalenone disrupts genome stability and inhibits growth of porcine granulosa cells via the estrogen receptors which may promote granulosa cell apoptosis when the DNA repair system is not enough to rescue this serious damage. At low concentrations, ZEN enhances cell proliferation, increases colony formation and fastens cell migration after wound healing. Zearalenone exhibits carcinogenesis-like properties.

In ovariectomized female ICR mice, s.c. administration of ZEN at doses ≥2 mg/kg/day for 3 consecutive days significantly increased uterine wet weight compared with the control group. Zearalenone is an immunotoxic compound similar to estrogen and some endocrine disruptors. After oral exposure, ZEA is rapidly absorbed and initially metabolized by the intestinal tissue and hepatocytes; this initiates the biotransformation of the compound into its major biologically active reductive metabolites, α- and β-zearalenol (α- and β-ZOL). The estrogenic activity of ZEA and its metabolites is mediated by their binding affinity to estrogen receptors (ER), and they are as potent as coumestrol and genistein, two endocrine-disrupting phytestrogens.
