Purpose To study the expression of zeb-1 and c-jun in gastric cancer and its influence of occurrence and development of tumor. Methods The expression zeb-1, c-jun and E-cadherin were assessed in 100 specimens of gastric cancer and their tissue adja-cent to cancer by immunohistochemistry. Results The positive rates of zeb-1,c-jun and E-cadherin expression in gastric cancer were 81%, 70%, 35%, and in tissue adjacent to cancer were 17%, 25%, 100%. The expression of zeb-1 and c-jun in gastric cancer were higher than those in their tissue adjacent to cancer (P<0. 05). zeb-1 expression was closely correlated with the degree of tumor differentiation, depth of invasion, lymph node metastasis and TNM stage (P<0. 05), which were not correlated with patient s age, sex and tumor size. c-jun expression was closely correlated with the degree of tumor differentiation (P<0. 05), which were not correlated with other pathological features. The expression of zeb-1 was negatively correlated with the expression of E-cadherin and was positively correlated with the expression of c-jun in gastric cancer. Patients with high expression of zeb-1 and c-jun had lower five-year survival rate than patients with negative expression. Conclusion zeb-1 and c-jun are closely correlated with occurrence and development of gastric cancer. They can be a index of judging prognosis of gastric cancer.

Objective To investigate the relationship between the expressions of TMPRSS4 and clinical pathologi-cal parameters in gastric carcinoma. To explore its significance in judging the prognosis of patients. To analyze the expression of TMPRSS4 in the epithelial-mesenchymal transition. Methods The expressions of TMPRSS4, E-cad-herin and Vimentin were detected by immunohistochemistry ( SABC) in 100 cases of gastric carcinoma specimens and corresponding adjacent normal tissue. Results In gastric carcinoma, TMPRSS4, E-cadherin and Vimentin positive rate was 47%,45%,37%. In adjacent tissues,their positive rate was 9%,30%,4%. The differences be-tween tumor tissues and adjacent tissues had statistical significance ( P<0.05 ) . High expression of TMPRSS4 cor-related significantly with lymph node metastases and TNM stage (P<0.05), but not with gender, age, size, tumor histological type,depth of invasion (P>0.05). The 5-year survival rate of patients with high TMPRSS4 expression was significantly lower than that in patients with low expression. The high TMPRSS4 expression was significantly correlated in gastric carcinoma accompanied by low expression of E-cadherin (rs = -0.207,P=0.038) and high Vimentin expression (rs=0.233,P=0.020). Conclusion The expression of TMPRSS4 is closely related to the biological characteristics in gastric carcinoma,detection the expression of TMPRSS4 is valuable in predicting tumor prognosis,invasion and metastasis. TMPRSS4 may promote invasion, metastasis of human gastric carcinoma through epithelial-mesenchymal transition by reduce the expession of E-cadherin.

BACKGROUNDMethylenetetrahydrofolate reductase (MTHFR) plays an important role in metabolism of folate and DNA methylation. In vitro, many studies have demonstrated that abnormal methylation of some genes may affect the sensitivity of tumor cells to cytotoxic drugs and agents interfering with DNA synthesis. The aim of this study is to investigate the relationship between genetic polymorphisms of MTHFR C677T or A1298C and the response to platinum-based chemotherapy in non-small cell lung cancer (NSCLC).

METHODSA total of 97 patients with NSCLC were analyzed. MTHFR genotypes were detected in all the patients by PCR-RFLP method. All the patients were treated with platinum-based chemotherapy.

RESULTS(1) Out of all the cases, the frequencies of MTHFR C677T C/C, C/T and T/T genotypes were 34.0%, 50.5% and 15.5%, respectively, while the frequencies of MTHFR A1298C A/A, A/C and C/C genotypes were 64.6%, 29.2% and 6.3%, respectively. The overall response rate (complete and partial response) to platinum-based chemotherapy was 39.2%. (2) No significant difference in response rate to chemotherapy was observed according to the MTHFR C677T or A1298C genotypes. However, MTHFR C677T and A1298C polymorphisms showed a synergic effect on chemotherapeutic efficacy, the response rate of patients with MTHFR C677T T allele and A1298C A/A genotype (51.1%) was significantly higher than those with MTHFR C677T C/T and A1298C C allele (12.5%)(P=0.007, OR=7.30, 95% CI: 1.34-52.47).

CONCLUSIONSThe results suggest that the synergic effect between MTHFR C677T and A1298C polymorphisms is associated with clinical response to platinum-based chemotherapy. Detection of MTHFR genotypes may indicate the sensitivity of NSCLC patients to platinum-based chemotherapy.
