Scientific Background :STAT3 is a member of the signal transducers and activators of transcription (STAT) family of proteins that carry out dual functions. STAT3 is a DNA binding protein that is widely expressed and becomes activated upon phosphorylation on Tyr708, which leads dimerization, intracellular translocation and DNA-binding. Phosphorylation at Ser727 regulates transcriptional activity. STAT3 is activated in response to variety of stimuli, which includes EGF, IL-6, PDGF, IL-2 and G-CSF (1). STAT3 forms homo- and hetero-dimers with other STAT proteins to modulate the transcription of various genes (2).
