Yet, the expression levels of both TP53 with inactivating mutations in the 49 ovarian cancer samples (p = 2.61×10−11, two tailed t-test) and wild-type TP53 in the 65 ovarian cancer samples (p = 0.001, two tailed t-test) were significantly lower than the expression levels of TP53 in the normal controls. This evidence concerns the gene TP53 and ovarian cancer.
