p53 induction of heparin-binding EGF-like growth factor counteracts p53 growth suppression through activation of MAPK and PI3K/Akt signaling cascades

Tumor suppressor p53 induction in response to cellular stresses activates the mitogen-activated protein kinase (MAPK) cascade through pathways involving Ras and RAF: p53's ability to activate this pathway is dependent on p53-mediated transcription. In order to investigate potential p53 target gene(s) involved, we utilized expression array analysis and identified heparin-binding epidermal growth factor-like growth factor (HB-EGF) as being...
