英文摘要: Abstract(#br)Signal transducer and activator of transcription factor 3 (STAT3) is a transcription factor that regulates various cellular processes such as proliferation, survival and angiogenesis in cancer cells. In the present study, we investigated the mechanisms whereby isothiocyanate sulforaphane (SFN) suppresses STAT3 activation in DU145 prostate cancer cells. SFN significantly inhibited SFN-inhibited STAT3 phosphorylation at Tyr705 as well as the deoxyribonucleic acid (DNA) binding capability in electrophoresis mobility shift assay (EMSA) in time- and concentration-dependent manner. SFN also abrogated the Janus activated kinase 2 (JAK2) phosphoraylation. In addition, SFN down-regulated STAT3-related gene products including Bcl-2, Bcl-x L , and cyclin D1 and vascular endothelial...
