Uteroglobin, a progesterone induced, pregnancy related protein, can be incorporated into higher molecular weight proteins by human placental Factor XIIIa. This process is time dependent, requires CaCl2 and can be inhibited by the addition of polylysine, dansylcadavarine or histamine. Crosslinking of uteroglobin into higher molecular weight proteins can also be brought about by guinea pig liver transglutaminase. Such a process may be involved in the modification of epididymal spermatozoa to suppress their antigenicity.

Uteroglobin (UG) or Clara Cell 10 kDa protein (CC10) is a small, stable, epithelial secretory anti-inflammatory protein. Uteroglobin has been shown to inhibit neointimal formation in vivo after balloon angioplasty through an unknown mechanism. An interaction between UG and plasma fibronectin (Fn) has been demonstrated in mice. Since Fn plays a key role in endothelial cell (EC) migration and angiogenesis, we investigated whether recombinant human UG (rhUG) affects EC migration via Fn binding. In this report, we show a saturable binding of rhUG to Fn depending on Fn conformation and that rhUG is covalently cross-linked to Fn by transglutaminase (TGase). Additionally, our study highlights that rhUG can also bind to exogenously added or self-secreted Fn on the membrane of human primary microvascular endothelial cells (HMVEC), although these complexes are weakly associated with the plasmalemma. Upon the interaction with Fn in solid phase, rhUG strongly inhibits HMVEC attachment on Fn, but not on other ECM proteins. Consequently, rhUG also inhibits cell migration in a dose dependent fashion (I.C.50 = 65 nM) and hinders the "wound healing" in vitro. The small size, stability and human tolerability of rhUG suggest that rhUG in slow-release form or genetically delivered could be used in humans to modulate cell/Fn interactions in the context of tumor microenvironment or in the context of inflammation and fibrosis.
