Homologous matings of Tinagl1-/- females and Tinagl1-/- males showed impaired fertility during pregnancy, including failure to carry pregnancy to term and perinatal lethality.

 

Blastocyst adhesion to the uterine epithelium stimulates the uterine stroma to form decidual tissue. Mass of decidual cells around embryo called deciduum is supported by extracellular matrix, which mediates crosstalk between deciduum and fetal cells and contributes to maintenance and protection of the fetus [1]. Tubulointerstitial nephritis antigen-like 1 (Tinagl1, also known as AZ-1 or lipocalin 7) is a secretory protein and is expressed in extraembryonic regions and uterine dediduum during postimplantation period [2-4]. Matsumoto and colleagues generated conditional Tinagl1 knockout mice to reveal the role of Tinagl1 during pregnancy. Although Tinagl1−/− embryos developed normally, homozygous female mice showed subfertility phenotype when mated with homozygous male [5]. Behavior of trophoblasts invading the uterus resembles to that of metastatic tumor cells, and recent studies indicate knockdown of Tinagl1 is associated with increased risk of cancer metastasis [6, 7]. Tinagl1 was also shown to be a proangiogenic matricellular protein in zebrafish [8]. Conditional Tinagl1 knockout strain will be a new tool to clarify the role of Tinagl1 in various tissues in mice.
