To investigate the role of TAp73 in ovarian cancer cells in response to cisplatin, human cisplatin-resistant ovarian cancer cell lines SKOV3 (null-p53) and OVCA433 (wild-type p53) were stably transfected with the plasmid pEGFP-TAp73α (Figure 1A). This evidence concerns the gene TP53 and ovarian carcinoma.
