Combination of neutrophil gelatinase-associated lipocalin and matrix metalloproteinase-9 are biomarkers for the detection of colon tubular adenocarcinoma

Figure 1 The relative expression of neutrophil gelatinase-associated lipocalin was consistent with the content of pro-gastrin-releasing peptide in serum. A: The relative gene expression of neutrophil gelatinase-associated lipocalin in serum in normal and six samples of tubular adenocarcinoma of the colon (P1 to P6); B: The content of pro-gastrin-releasing peptide (pg/mL) in serum. Three independent experiments were carried out and analyzed. Data are expressed as mean values ± SE, ^bP < 0.01, two-tailed Student’s t-tests. NGAL: Neutrophil gelatinase-associated lipocalin; pro-GRP: Pro-gastrin-releasing peptide.
