Objective To investigate the relationships of peroxisome proliferators activated receptor γ(PPARγ) and matrix metallo protease-7 ( MMP-7) with gastric cancer ( including low and high grade atypical hyperplasia). Methods One hundred and twenty gastric tissue specimens (four groups) were collected by gastroscopy or surgical operation, including 31 patients with chronic gastritis, 25 patients with low-grade atypical hyperplasia, 27 patients with high-grade atypical hyperplasia, and 28 patients with gastric cancer. The expression of PPARγ and MMP-7 were observed by immunohistochemical technique and analyzed by statistic methods. Results Both of them have high expression in the groups of gastric cancer respectively, and the high combined expressions of them were found in gastric cancer and high-grade atypical hyperplasia. Conclusion PPARγ and MMP-7 were the important differential signs of the gastric cancer and precancer by inference, the combined expression of PPARγ and MMP-7 was the evidences in differential diagnosis among gastric cancer, high and low grade atypical hyperplasia and gastritis.
