For example, Priya et al. [60] used a combination of the WTp53 gene and trace doxorubicin (Dox) (1 μM) to mediate up to 98% of tumor cell mortality rate, whereas treatment with the same amount of p53 genes and higher levels of Dox (3.13 μM) alone resulted in only 59% and 50% tumor cell mortality rate. The gene discussed is TP53; the disease is neoplasm.
