AIM: To investigate the expression of AKT, p27Kip1 and cyclin E proteins in gastric carcinoma and to explore their significance in tumor development and progression.
METHODS: Biopsy and surgical specimens were collected in the Xiangtan City First People's Hospital and Affiliated Nanhua Hospital of University of South China from January 2008 to January 2010, including 14 cases of normal gastric mucosa, 10 cases of atypical hyperplasia, 94 cases of gastric cancer, 49 cases of cancer-adjacent tissue and 35 cases of metastatic cancer. Tissue array technology was used to detect the phosphorylation of AKT and p27Kip1 proteins and the expression of cyclin E by immunohistochemistry.
RESULTS: Compared to normal gastric mucosa, cancer-adjacent tissue and atypical hyperplasia, the positive rates of AKT phosphorylation and cyclin E overexpression were significantly higher (AKT: 85.1%, 85.7% vs 14.3%, 26.5%, 30.0%; Cyclin E: 85.1%, 82.9% vs 14.3%, 34.7%, 20.0%, all P < 0.01) and that of p27Kip1 phosphorylation was significantly lower (22.3%, 17.1% vs 71.4%, 44.9%, 40.0%, all P < 0.01) in primary cancer and metastatic carcinoma. Compared to normal gastric mucosa, the positive rate of AKT phosphorylation was significantly higher in atypical hyperplasia (P = 0.26).
CONCLUSION: The phosphorylation of AKT and p27Kip1 and expression of cyclin E protein are possibly related to the development and progression of gastric carcinoma.
