---|---|---|---|---|---|---|---|
WiDR | w.t. | mut | mut | w.t | w.t. | 8.2 ± 0.8 | 3.2 ± 0.3 |
Lovo92 | w.t. | w.t. | w.t. | mut | w.t. | 4.4 ± 1.3 | 0.9 ± 0.1 |
Colo320 | w.t. | w.t.† | w.t. | mut | w.t. | 3.2 ± 0.3 | 0.6 ± 0.1 |
Caco2 | w.t. | w.t. | w.t. | w.t. | w.t. | 0.3 ± 0.1 | 25 ± 2.0 |
†Colo320 is w.t. p53, but lacks p21 (see Fig. 1) and therefore behaves as a mutant. EGFR, epidermal growth factor receptor; mut, mutant; TFT, trifluorothymidine; w.t., wild type.
