... achieving inhibition of tumour cell proliferation.Indeed, its inhibition results in cell death. We previously observed that inhibition of the transcription factor nuclear factor- jB, a key regulator of cell ... induction of cell death. Several therapeutic approaches have beendeveloped to inhibit STAT3, including inhibition of itsexpression [14,15], inhibition of its dimerization [16,17]and inhibition of ... doxorubicin [43]. Thus, theefficiency of blocking STAT3 may depend onthe absence of the inhibition of STAT1. Indeed, celldeath induced by ODN and by IFN-c may be theresult of completely different mechanisms....
