产品描述:
Signal transducers and activators of transcription (STATs) are a family of latent cytoplasmic transcription factors that convey signals from the cell membrane to the nucleus. In various human tumors, STAT3 is constitutively activated by aberrant upstream tyrosine kinase activities.{23053} Stattic is a small molecule inhibitor of STAT3.{23053} It selectively inhibits STAT3 activation, dimerization, and nuclear translocation by preventing the binding of tyrosine-phosphorylated peptide motifs to the STAT3 SH2 domain (IC50 = 5.1 μM at 37°C).{23053} At 10 μM, stattic induces apoptosis in STAT3-dependent breast cancer (MDA-MB-231 and MDA-MB-435S) cell lines.{23053}
