- _5 value "The suppressor of cytokine signalling (SOCS) protein family negatively regulates cytokine action. In this study, we investigated the effects of estrogen (E2) on SOCS-3 expression in T47D and MCF-7 human breast cancer cells. Real-time PCR analysis of E2-treated T47D cells revealed a ligand and time-dependent increase in of SOCS-3 mRNA levels. Cloning of a 1.7 kb fragment of the human SOCS-3 5' flanking sequence, and subsequent analysis of potential transcription factor-binding sites identified an incomplete ERE motif located -1493 to -1489 upstream of the start site. Transient transfection of the cloned fragment in MCF-7 cells showed that both E2 and genistein treatment caused an increase in reporter gene activity, which was inhibited by co-treatment with ICI 182,780. Chromatin immunoprecipitation analysis revealed an E2 and time-dependent recruitment of ERalpha to the E2 responsive region of the human SOCS-3 promoter. In summary, this study shows that ERalpha directly regulates human SOCS-3 promoter activity in human breast cancer cells, thus modulating cytokine activity." provenance.
