Background	STAT (Signal Transducers and Activators of Transcription) proteins play important roles in development, cell differentiation and cell cycle control. STAT3 is an ~85 kDa protein involved in the signaling pathways of many cytokines and growth factors, including G-CSF and IL-6, where it functions as a negative regulator of transcription. STAT3 is also constitutively activated in a number of human tumors and it possesses anti-apoptotic activity and oncogenic potential. STAT3 may also regulate apoptosis by inhibiting NF-κB. Activation of STAT3 by tyrosine phosphorylation results in dimerization, nuclear translocation and DNA binding.
