We sought to determine the activities of various environmental estrogens on the modulation of the interleukin-1beta ( IL-1beta ) gene in a model monocytic cell line , hER + IL-1beta -CAT+ .
 ( protein: IL-1beta, None) , ( protein: interleukin-1beta, None) , ( DNA: interleukin-1beta ( IL-1beta ) gene, None) , ( cell line: model monocytic cell line, None) , ( protein: IL-1beta, None) , ( cell line: hER + IL-1beta -CAT+, None)
