Although mutant-p53-dependency appeared to be verified in five studies for breast cancer [12,14,15,45,61] and four studies for thyroid cancer [31,38,39,47], the conclusions must be nuanced because of several results were obtained using the same cell lines and by the same team ([12,14,15], and [38,39], respectively). The gene discussed is TP53; the disease is thyroid gland carcinoma.
