A microarray-based gastric carcinoma prewarning system

Figure 1 Results of high-density chip hybridization with gastric tissues. Red and yellow: higher gene expression levels. Green and blue: lower gene expression levels.

Figure 2 Cluster analysis of low-density-chip-examination results of 150 specimens.

Figure 3 Northern blot analysis of brcaa1 and ndr1. A: brcaa1: lanes 1, 3, 5: Normal gastric tissues; lanes 2, 4, 6: Gastric cancer tissues; B: ndr1: lanes 1, 3, 5, 7: Gastric cancer tissues; lanes 2, 4, 6: Normal gastric tissues.

Figure 4 Immunohistochemistry analysis of brcaa1 and ndr1. A: Brcaa1 expression in normal gastric mucosa tissues (200 size); B: Brcaa1 expression in gastric cancer tissues (400 size); C: Ndr1 expression in normal gastric mucous tissues (200 size); D: Ndr1 expression in gastric cancer tissues (200 size).
