Iron 59-63 lipocalin 2 Homo sapiens 0-42 19549696-0 2009 Neutrophil gelatinase-associated lipocalin (NGAL) reflects iron status in haemodialysis patients. Iron 59-63 lipocalin 2 Homo sapiens 44-48 19549696-4 2009 iron administration significantly increased NGAL values from baseline. Iron 0-4 lipocalin 2 Homo sapiens 44-48 19549696-7 2009 CONCLUSIONS: The findings demonstrated that HD patients have altered NGAL values probably because this protein is involved in the maintenance of iron equilibrium. Iron 145-149 lipocalin 2 Homo sapiens 69-73 19549696-8 2009 Finally, NGAL might be proposed as a new tool in the assessment of iron deficiency and in the management of iron therapy for HD patients. Iron 67-71 lipocalin 2 Homo sapiens 9-13 19308044-5 2009 Furthermore, we observed that the NGAL-overexpressing cells tolerated increased iron levels in the culture environment, whereas the NGAL-underexpressing cells showed significant cell death after prolonged incubation in high-iron condition. Iron 80-84 lipocalin 2 Homo sapiens 34-38 19308044-5 2009 Furthermore, we observed that the NGAL-overexpressing cells tolerated increased iron levels in the culture environment, whereas the NGAL-underexpressing cells showed significant cell death after prolonged incubation in high-iron condition. Iron 110-114 lipocalin 2 Homo sapiens 34-38 19308044-6 2009 Thus, overexpressing NGAL in colon carcinomas is an important regulatory molecule that integrates extracellular environment cues, iron metabolism, and intracellular small GTPase signaling in cancer migration and invasion.

Iron 55-59 lipocalin 2 Homo sapiens 73-77 16775460-7 2006 While the structure of the NGAL: siderophore: iron complex has thus far only been solved for bacterially synthesized siderophores, new evidence suggests the presence of mammalian siderophore-like molecules. Iron 46-50 lipocalin 2 Homo sapiens 27-31 16775460-8 2006 SUMMARY: NGAL is rapidly and massively induced in renal epithelial injury and NGAL: siderophore: iron complexes may comprise a physiological renoprotective mechanism. Iron 97-101 lipocalin 2 Homo sapiens 78-82 16622025-1 2006 Neutrophil gelatinase-associated lipocalin (NGAL) is a siderophore-binding protein that exerts a bacteriostatic effect by sequestering iron. Iron 135-139 lipocalin 2 Homo sapiens 0-42 16622025-1 2006 Neutrophil gelatinase-associated lipocalin (NGAL) is a siderophore-binding protein that exerts a bacteriostatic effect by sequestering iron. Iron 135-139 lipocalin 2 Homo sapiens 44-48 15691834-5 2005 Lipocalin 2 action was enhanced by iron-siderophore. Iron 35-39 lipocalin 2 Homo sapiens 0-11 15637066-2 2005 In the present study, we demonstrate that HGF stimulates epithelial cells to express neutrophil gelatinase-associated lipocalin (Ngal), a member of the lipocalin family of secreted proteins that has recently been shown to participate in mesenchymal-epithelial transformation via its ability to augment cellular iron uptake. Iron 311-315 lipocalin 2 Homo sapiens 129-133 15637066-3 2005 At concentrations below those found to mediate iron transport, purified Ngal can induce a promigratory and probranching effect that is dependent on ERK activation. Iron 47-51 lipocalin 2 Homo sapiens 72-76 15531878-0 2004 Lipocalin 2 mediates an innate immune response to bacterial infection by sequestrating iron. Iron 87-91 lipocalin 2 Homo sapiens 0-11 15670845-0 2005 The endocytic receptor megalin binds the iron transporting neutrophil-gelatinase-associated lipocalin with high affinity and mediates its cellular uptake. Iron 41-45 lipocalin 2 Homo sapiens 59-101 15670845-2 2005 NGAL binds bacterial siderophores preventing bacteria from retrieving iron from this source. Iron 70-74 lipocalin 2 Homo sapiens 0-4 15670845-3 2005 Also, NGAL may be important in delivering iron to cells during formation of the tubular epithelial cells of the primordial kidney. Iron 42-46 lipocalin 2 Homo sapiens 6-10 15531878-7 2004 Upon encountering invading bacteria the Toll-like receptors on immune cells stimulate the transcription, translation and secretion of lipocalin 2; secreted lipocalin 2 then limits bacterial growth by sequestrating the iron-laden siderophore. Iron 218-222 lipocalin 2 Homo sapiens 156-167 15282194-3 2004 The reporters were also sufficiently sensitive to distinguish apo- from holotransferrin in the medium, to detect the effect of modifiers of the transferrin pathway such as HFE, and to detect the donation or chelation of iron by siderophores bound to the lipocalin neutrophil gelatinase-associated lipocalin (Ngal). Iron 220-224 lipocalin 2 Homo sapiens 308-312 12788784-5 2003 We review the data showing that lipocalins transport low-molecular-weight chemical signals and data indicating that 24p3/NGAL transports iron. Iron 137-141 lipocalin 2 Homo sapiens 121-125 14627119-4 2003 In contrast, 24p3/Ngal targets early progenitors at the kidney"s periphery through an iron-mediated, but a transferrin-independent mechanism. Iron 86-90 lipocalin 2 Homo sapiens 18-22 12788784-6 2003 We compare 24p3/NGAL to transferrin and a variety of other iron trafficking pathways and suggest specific roles for each in iron transport. Iron 59-63 lipocalin 2 Homo sapiens 16-20 12788784-6 2003 We compare 24p3/NGAL to transferrin and a variety of other iron trafficking pathways and suggest specific roles for each in iron transport.
