TP53 and non-small cell lung carcinoma: Furthermore, following the 1 μmol/L treatment of the NSCLC cell pair (Figure 3A and Figure 3B), there is clearly a greater loss of proliferation noted for the TP53 MUT cell H23 (Figure 3B) upon treatment, compared to the TP53 WT cell A549 (Figure 3A); the decrease in cell growth being highly significant at days 3–4 for the H23 cells, compared the growth of the untreated cells.
