TP53 and ovarian carcinoma: Mut-p53 (R248) is overexpressed in ovarian cancer cell lines, which can interact with double-strand-break repair protein rad21 (Rad21) and upregulate the expression of Rad21 target genes, sphingosine-1-phosphate receptor 1 (S1PR1), and thrombospodin 1 (THBS1), that related to cell migration in intact cells or cancer cell lines (73).
