STAT3 mainly acts as a signal transducer of IL-6 family cytokines and transcriptionally activates specific target genes. STAT3 has also been demonstrated to mediate cellular transformation and is found in numerous cancers. Endocrine-disrupting chemicals (EDCs) are a diverse group of chemicals that bind to estrogen receptors (ERs), mimic estrogenic actions, and may have adverse effects on human health. In our previous study, we demonstrated that estrogens suppressed the STAT3-mediated transcription activity through ERs. In this study, we examined the effects of EDCs on STAT3-mediated signaling through ERs. Surprisingly, some of EDCs enhanced STAT3-mediated transcription activity through ERs. This finding strongly suggests that EDCs may play an important role in the endocrine functions by mimicking cytokine activity by stimulating STAT3 actions through ERs. (C) 2004 Elsevier Inc.
