Growth, invasion, metastasis, differentiation, angiogenesis and apoptosis of gastric cancer regulated by expression of PTEN encoding products

Table 1 PTEN expression in adjacent epithelial cells and cancer cells of primary gastric cancer

Groups	n	PTEN expression
		-	+	++	+++	PR(%)
Adjacent epithelial cells	113	12	10	23	68	89.4
Primary cancer cells	113	51	13	11	38	54.9a

Notes: PR: positive rate,

^aP = 0.000 (χ² = 33.474, Pearson’R = 0.385).
