BACKGROUND Detection of acute kidney injury (AKI) is still a challenge if conventional markers of kidney function are within reference range. We studied the sensitivity and specificity of NGAL as an AKI marker at different degrees of renal ischemia. METHODS Male C57BL/6J mice were subjected to 10-, 20- or 30-min unilateral renal ischemia, to control operation or no operation, and AKI was eval...
Neutrophil gelatinase-associated lipocalin (NGAL) is a 25 kDa protein with roles in iron trafficking as well as in carcinogenesis and progression of several human neoplasias. Although the renal proximal tubule represents a major source of NGAL synthesis under various injurious stimuli to the kidney, NGAL expression has been rarely evaluated in renal tumors up to now. In view of this, in the pre...
Lipocalin 2 (LCN2), a multifunctional secretory protein known as neutrophil gelatinase-associated lipocalin (NGAL), is expressed in a variety of cancers. However, little is known about the biological functions of NGAL in the development of lung adenocarcinoma. In the present study, we primarily found that NGAL expression was up-regulated in human lung adenocarcinoma tissues. Additionally, deple...
BACKGROUND AND OBJECTIVES Neutrophil gelatinase-associated lipocalin (NGAL) is rapidly released by renal tubules after injury, potentially allowing early identification of acute kidney injury (AKI) after cardiac surgery. However, the diagnostic performance of NGAL has varied widely in clinical studies, and it remains unknown what factors modify the relationship between NGAL and AKI. We hypothes...
BACKGROUND Neutrophil gelatinase-associated lipocalin (NGAL), an acute phase protein released by neutrophils, has been described as biomarker of inflammatory states. Type 2 diabetes mellitus (T2DM) is characterized by increased inflammation and an elevated risk for embolization of carotid artery stenosis (CAS). We aimed to explore the role of NGAL systemically and in plaques of diabetics underg...
INTRODUCTION Plasma neutrophil gelatinase-associated lipocalin (NGAL) is reportedly useful for post-cardiac surgery acute kidney injury (AKI). Although chronic kidney disease (CKD) is a strong risk factor for AKI development, no clinical evaluation of plasma NGAL has specifically examined AKI occurring in patients with CKD. This study evaluated plasma NGAL in AKI superimposed on CKD after cardi...
INTRODUCTION Acute kidney injury (AKI) is a frequent complication of cardiopulmonary bypass (CPB). The lack of early biomarkers has impaired our ability to intervene in a timely manner. We previously showed in a small cohort of patients that plasma neutrophil gelatinase-associated lipocalin (NGAL), measured using a research enzyme-linked immunosorbent assay, is an early predictive biomarker of ...
Introduction: We tested the hypothesis that urinary and serum neutrophil gelatinase-associated lipocalins (NGAL) early after non-cardiac major surgery predict postoperative acute kidney injury (AKI), complications and mortality. Methods: We studied 74 patients undergoing orthopedic, vascular and abdominal surgery lasting 6 2 h. NGAL was measured in preoperative, as well as 2and 6-hour postopera...
In a previous search for the differentially expressed genes in keratinocyte differentiation, we identified neutrophil gelatinase-associated lipocalin (NGAL) as a calcium-induced gene. In this study, we further verified the expression of NGAL in cultured keratinocytes as well as in several skin diseases. Reverse transcription-polymerase chain reaction (RT-PCR), Western blot, and ELISA clearly sh...
A growing body of evidence points towards smoking-related phenotypic differences in chronic obstructive pulmonary disease (COPD). As COPD is associated with systemic inflammation, we determined whether smoking status is related to serum levels of matrix metalloproteinase-9 (pro- and active MMP-9), neutrophil gelatinase-associated lipocalin (NGAL) and the proMMP-9/NGAL complex in patients with C...
