Functional interaction between S100A1 and MDM2 may modulate p53 signalling in normal and malignant endometrial cells

S100A1 expression is deregulated in a variety of human malignancies, but its role in normal and malignant endometrial cells is unclear. Methods: We used endometrial carcinoma (Em Ca) cell lines to evaluate the physical and functional interaction of S100A1 with p53 and its negative regulator, mouse double minute 2 (MDM2).
