Gene expression threshold for distinguishing three kinds of gastric mucosa.

Gene classification	Gastric cancer tissue (GC/N)	Precancerous lesion (PC/N)	*Normal gastric mucosa (N^/GC or N^/PC)*
216 genes associated with gastric cancer	6.01±2.40	1.18 ±0.47	< 0.75
85 genes associated with precancerous lesions	1.32±0.53	4.86±1.94	2.54±0.41
88 genes associated with normal mucosa	1.31±0.54	2.50±0.75	5.42±2.17
15 genes associated with metastasis of gastric cancer	5.81±2.32 (M)2.32±1.19 (N¹)	1.13±0.58	0.65±0.35
8 genes associated with risk factors		>2.0

Specification: The above data indicate the relative expression levels between GC/N, PC/N, N/PC and N/GC mean ratio and minimum values. M: Metastasis; N1: No metastasis. GC: Gastric cancer; PC: Precancerous lesion; N: Normal mucosa. N^*: Selected gene expression levels in normal gastric mucosa.
