ABSTRACT
AIMS:
Although many markers were associated with abdominal aortic aneurysm (AAA), there is no clear consensus on which marker is of the most value. Studies have implicated the role of Notch signaling in the pathogenesis of AAA. We investigate the value of plasma Jagged1, Notch receptors and tumor necrosis factor-α converting enzyme (TACE) in identifying AAA. MAINMETHODS:
42 patients with AAA and 36 controls were enrolled in our study. The concentrations of plasma Jagged1, Notch receptors and TACE were measured by enzyme-linked immunosorbent assay (ELISA). The diagnostic value of plasma Notch1 and TACE was assessed by logistic regression and receiver operator characteristic (ROC) curve. Double immunofluorescence staining was used to investigate the distribution of Notch1 and TACE in AAA tissue specimens. KEYFINDINGS:
The concentrations of plasma Notch1 and TACE were significantly higher in AAA than in the controls, respectively (Notch1 P < 0.001; TACE P = 0.0001). The area under the curve (AUC) from ROC curve of plasma Notch1 and TACE in determining the presence of AAA was 0.878 and 0.804, respectively. Combining detection of plasma Notch1 and TACE could improve the accuracy in detecting AAA (AUC 0.984, P < 0.0001). The predicted probability cutoff of 0.70 gave a sensitivity of 90.5% and a specificity of 100% for combining detection of plasma Notch1 and TACE in predicting AAA.SIGNIFICANCE:
This is the first report revealing that plasma Notch1 and TACE are highly expressed in AAA. Combining detection of plasma Notch1 and TACE may be reliable for identifying the presence of AAA.Key words
