NF-kappaB enhances cell proliferation, but also ATF-2 or Elk-1. Since IL-1 and TNF-alpha are related to inflammation and their immunoexpression increases in PC, inhibition of these cytokines might be a possible target for PC treatment, because they decrease the activity of all transduction pathway members that activate transcription factors such as NF-kappaB, Elk-1 or ATF-2.
