Lipocalin-2 (Lcn2) is a small glycoprotein involved in a number of biological processes such as inflammation and antibacterial response. In our study, Lcn2 is expressed in the subluminal stromal cells at implantation site on day 5 of pregnancy. The expression of Lcn2 in stromal cells is under the control of progesterone through Akt-c-Myc signaling pathway. Data from Lcn2 knockdown and recombinant protein treatments indicate that Lcn2 promotes mPGES-1 expression in stromal cells. The expression of Lcn2 and mPGES-1 is strongly stimulated by lipopolysaccharide (LPS), indicating that Lcn2 mediates LPS-induced inflammation. These findings shed light on the role of Lcn2 during decidualization.
