Abstract

14‑3‑3 proteins participate in various cellular processes, including apoptosis, proliferation and malignant transformation. 14‑3‑3σ, a member of the 14‑3‑3 protein family, is important in several types of cancer; however, little is known about the clinical significance and biological roles of 14‑3‑3σ in gastric cancer. The present study analyzed the expression pattern of 14‑3‑3σ in gastric cancer and investigated its correlation with the prognosis of gastric cancer patients. Furthermore, the association of 14‑3‑3σ with Ki‑67, Bcl‑2 and Bax was evaluated. 14‑3‑3σ was expressed at higher level in gastric cancer tissue compared with healthy gastric tissue, and 14‑3‑3σ expression was significantly correlated with tumor size and tumor node metastasis stage (P<0.05). To the best of our knowledge, the present study data are the first to suggest that 14‑3‑3σ expression has been significantly associated with poor prognosis in gastric cancer. Additionally, 14‑3‑3σ overexpression was positively correlated with Ki‑67 and Bcl‑2 expression levels. Thus, 14‑3‑3σ is a potential prognostic marker for gastric cancer patients, and may be involved in regulating the apoptosis and proliferation of gastric cancer cells.
