In two estrogen-sensitive cell lines, Le42 and MCF-7, the estrogenic potential of the nonsteroidal mycotoxin zearalenone has been investigated. The chloramphenicol acetyltransferase (CAT) gene expression in Le42 cells is induced by zearalenone after transfection with a CAT-gene construct controlled by an estrogen responsive element [(1986) Cell 46, 1053-1061]. In MCF-7 cells zearalenone induces at least 2 exoproteins (52 and 160 kDa) which are estrogen-specific [(1980) Cell 20, 353-362). These data suggest that zearalenone acts by activating the estrogen receptor. Due to the high sensitivity of these cell lines for zearalenone both test systems are proposed as assays for a quantitative estimation of the biological (estrogenic) activity of this widespread mycotoxin.
