To see if any of the above genes/pathways could be regulated by Δ133p53α or Δ133p53β, we identified 318 genes defining Group A cancers that had p53/p63/p73 response elements in their promoters36 (Spearman’s correlation coefficient (ρ) cutoff of >0.5, Fig. 7a). The gene discussed is TP63; the disease is cancer.
