  • Correlation study of expressions of silence signal regulating factor-1 and E-cadherin in gastric cancer

    Objective To investigate expressions of silence signal regulating factor-1 (SIRT-1) and epithelial cadherin (E-cadherin) in gastric cancer and their clinical significances. Methods The immunohistochemistry SP technique was used to detect the expressions of SIRT-1 and E-cadherin in the gastric cancer tissues and their corresponding paracancerous gastric tissues. The relationship between the SIRT-1 expression and E-cadherin expression was analyzed using Spearman. Results The positive rate of the SIRT-1 protein expression in the gastric cancer tissues was significantly higher than that of the corresponding paracancerous gastric tissues (χ2=5.791, P=0.016). The SIRT-1 protein positive expression was related to the Lauren histological type of gastric cancer (χ2=4.941, P=0.026), in other words, in the intestinal type was significantly higher than that of the diffuse type, but which was not related to the age, gender, tumor size, tumor site, differentiation degree, TNM stage, or lymph node metastasis (P>0.05). While the positive rate of the E-cadherin protein expression in the gastric cancer tissues was significantly lower than that of the corresponding paracancerous gastric tissues (χ2=10.868, P=0.001), which in the intestinal type of gastric cancer was significantly lower than that in the diffuse type of gastric cancer (χ2=5.203, P=0.023), also not related to the age, gender, tumor size, tumor site, differentiation degree, TNM stage, or lymph node metastasis (P>0.05). There was a negative correlation between the SIRT-1 protein and the E-cadherin protein (rs=–0.381, P=0.013). Conclusions Gastric cancer with higher SIRT-1 expression might be way to achieve tumor development through E-cadherin as a facilitator. Upregulation of SIRT-1 and declining of E-cadherin might play a possible role in intestinal type gastric cancer.
