However, transient overexpression of N1ICD has been reported to inhibit wild-type p53-induced apoptosis in immortalized epidermal cells [30], to inhibit dexamethasone, etoposide, or Fas-ligand-induced apotosis in mature T-cells [31], and to protect H460 (lung cancer), HepG2 (liver cancer), and HT1080 (fibrosarcoma) from several chemotherapy drugs [32]. Here, TP53 is linked to fibrosarcoma.
