Background
Neutrophil gelatinase-associated lipocalin(LCN2) is a secreted protein and belongs to the calycin superfamily. This protein is released from injured tubular cells after various damaging stimuli; is already known by nephrologists as one of the most promising biomarkers of incoming Acute Kidney Injury (AKI). Recent evidence also suggests its role as a biomarker in a variety of other renal and non-renal conditions. Moreover; recent studies seem to suggest a potential involvement of this factor also in the genesis and progression of chronic kidney diseases. NGAL is the first known mammalian protein which specifically binds organic molecules called siderophores; which are high-affinity iron chelators. NGAL; first known as an antibacterial factor of natural immunity; and an acute phase protein; is currently one of the most interesting and enigmatic proteins involved in the process of tumor development. acting as an intracellular iron carrier and protecting MMP9 from proteolytic degradation; NGAL has a clear pro-tumoral effect; as has already been observed in different tumors (e.g. breast; stomach; oesophagus; brain) in humans. In thyroid carcinomas; NGAL is strongly induced by NF-kB; an important factor involved both in tumor growth and in the link between chronic inflammation and neoplastic development. Thus; Lipocalin-2 (LCN2/NGAL) has been implicated in a variety of processes including cell differentiation; proliferation; survival and morphogenesis.
