Abstract
Introduction: Gastric cancer (GC) is the fourth most common type of neoplasm and the second cause of malignancy-related death across much of the world. Complex multi-factorial processes are involved in its genesis, classified in two determinant clusters: non-genetic and genetic. Variation in CDH1 gene expression may play an important role in increasing risk of diffuse and intestinal subtypes of GC. This tumor suppressor gene, located on chromosome 16q22.1, encodes a trans membrane glycoprotein called epithelial cadherin (E-cadherin). Materials and Methods: In this historical cohort study, from June 2004 to Journey 2005 we collected 50 samples from Kurdish patients with stage II pathologically diagnosed gastric cancer that underwent surgery. Tumor tissues were paraffin-embedded along with 54 control samples from non-ulcer dyspepsia (NUD) cases undergoing upper gastrointestinal endoscopy. Three biopsies were captured by endoscopy from each individual’s gastric antrum. Result: The mean age of the patients was 59.5±2 years. Some 23 cases (53.4%) had the CC genotype, 19 AC and 1 AA. H.pylori infection was noted in 30 patients (69%). Survival rates of gastric cancer patients were 90.7% in the first year, 39.5% in the second year and 6.9% in the third year. Female patients had higher survival rates (P=0.004). Conclusion: In this study we found that frequencies of -160(C>A) CDH1 genotypes were not comparable in H.pylori-infected and H.pylori-uninfected subjects in both case and control groups. These findings suggest that -160 (C>A) CDH1 polymorphism is not related with H.pylori infection susceptibility. In addition we found no significant relationship between the CDH1 -160(C/A) promoter polymorphism with predisposition to gastric cancer.

Abstract
Computational methods were employed to determine progression inference of genomic alterations in commonly occurring cancers. Using cross-sectional TCGA data, we computed evolutionary trajectories involving selectivity relationships among pairs of gene-specific genomic alterations such as somatic mutations, deletions, amplifications, downregulation, and upregulation among the top 20 driver genes associated with each cancer. Results indicate that the majority of hierarchies involved TP53, PIK3CA, ERBB2, APC, KRAS, EGFR, IDH1, VHL, etc. Research into the order and accumulation of genomic alterations among cancer driver genes will ever-increase as the costs of nextgen sequencing subside, and personalized/precision medicine incorporates whole-genome scans into the diagnosis and treatment of cancer.

Abstract
Aberrant activation of the Wnt signalling pathway is a key feature of many cancers. β-Catenin, adenomatous polyposis coli (APC) and E-cadherin are major players in this pathway. The aim of this study is to examine the expression of β-catenin, APC and E-cadherin in tumour tissues of 80 Tunisian patients with gastric carcinoma and to determine the methylation status of the APC promoter in tumour tissues. Associations between protein expression and clinico-pathological parameters, including prognosis, were performed. Positive expression of β-catenin, APC and E-cadherin was observed in 77.5, 68.7 and 60% of cases, respectively. Tumours lacking membranous expression of β-catenin had greater extent of lymph node metastasis, poor differentiation and advanced T-stage. The expression of E-cadherin correlated with poor differentiation (P = 0.05) and β-catenin expression (P = 0.004). With regards to prognosis, the overall survival time was significantly prolonged for patients showing normal β-catenin expression (exclusively or predominantly membranous staining) alone or combined with positive APC expression (P log rank = 0.008 and 0.003, respectively). The methylated pattern of APC promoter 1A was detected in 43.8% of cases and correlated with T-stage (P = 0.046) and distant metastasis (P = 0.037). No correlation was found between the methylated profile of APC promoter 1A and the expression of APC protein in tumour tissues. Our findings suggest that deregulation of the Wnt pathway via abnormal expression of β-catenin and E-cadherin occurred frequently in gastric carcinoma and correlated with worse clinical behaviour.

Abstract
OBJECTIVE To investigate the expressions of caveolin-1, E-cadherin and β-catenin in gastric carcinoma, precancerous gastric and chronic non-atrophic gastritis tissues, and evaluate the correlation of these expressions with the development of gastric cancer. METHODS The expressions of caveolin-1, E-cadherin and β-catenin were detected by biotin-streptavidin- peroxidase (SP) immunohistochemistry on 58 gastric cancer tissues, 40 precancerous gastric tissues and 42 chronic non-atrophic gastritis tissues. The correlation between the expressions of caveolin-1, E-cadherin and β-catenin, and the clinicopathologic parameters of gastric cancer was analyzed retrospectively. RESULTS The positive rates of caveolin-1 and E-cadherin expressions in gastric carcinoma were significantly lower than precancerous gastric and chronic non-atrophic gastritis tissues (P<0.01). An abnormal rate of β-catenin expression in gastric carcinoma was higher than precancerous gastric and chronic non-atrophic gastritis tissues (P<0.01). Moreover, low expressions of caveolin-1, E-cadherin and β-catenin correlated with tumor size, depth of invasion, lymph node metastasis and TNM stage (P<0.05). The positive rates of caveolin-1 and E-cadherin expressions decreased (P<0.01), while an abnormal rate of β-catenin expression increased inversely, with the degree of atypical hyperplasia (P<0.01). Caveolin-1 expression correlated positively with E-cadherin (r=0.41, P<0.05). Caveolin-1 (r=-0.36, P<0.05) and E-cadherin (r=-0.45, P<0.05) expressions negatively correlated with abnormal β-catenin expression. CONCLUSION These results suggested that dysregulated expressions of caveolin-1, E-cadherin and β-catenin correlated with the development of gastric cancer and its biological behavior.

Abstract
The associations between E-cadherin (CDH1) gene polymorphisms and gastric cancer (GC) susceptibility are still controversial. Given this uncertainty, we carried out a meta-analysis of published case-control studies to derive more precise estimations of these relationships. Relevant studies were identified from PubMed and EMBASE up to March 2011. Seventeen studies with 3511 GC cases and 4826 controls were selected. Crude odds ratios (OR) and 95% confidence intervals (CI) were used to investigate the strength of the associations. No associations between CDH1 (+54T>C, -160C>A, -347G>GA, -616G>C, -2076C>T and -3159T>C) gene polymorphisms and GC risk for all genetic models were found. As for CDH1 -160C>A polymorphism, subgroup analyses by country, gender, study design, smoking status, Helicobacter pylori infection, and the Lauren classification of GC did not change the results. When stratified by ethnicity, we found the A allele carriers had a significantly increased risk of GC among Caucasians (AA vs. CA+CC: OR=1.50, 95% CI=1.03-2.19, P=0.03), but not among Asians (AA vs. CA+CC: OR=0.87, 95% CI=0.56-1.37, P=0.56). No publication bias was found in the present study. This meta-analysis suggests that CDH1 -160C>A gene polymorphism may contribute to increased risk of GC among Caucasians.

Abstract
UNLABELLED ERas activation and GKN2 reduction in gastric cancer has raised some notices in recent years, while nuclear beta-catenin positivity is considered as a tumoral marker. In this study, we compared immunohistochemistry of beta-catenin, GKN2 and ERas on tumoral and non-tumoral mucosae of 50 gastric carcinomas and 13 gastric samples of cancer-free patients. Nuclear positivity of beta-catenin was strong in 31 non-tumoral mucosae (62%) and 29 tumoral mucosae (58%). It was absent in samples of cancer-free patients. There was a correlation between non-tumoral and tumoral zones for nuclear beta-catenin positivity (P=0.013). ERas was positive in 35 non-tumoral tissues (70%) and 31 tumoral tissues (62%) but negatvie in samples of cancer-free patients. It was weak and spotty in non-tumoral mucosae but strong and diffuse in tumors. Positivity of ERas was age-related (P=0.028). However it had background staining effect. GKN2 was expressed in 33 non-tumoral mucosae (66%) and 35 tumoral mucosae (70%). Though GKN2 staining was moderate to strong in non-tumoral tissues and was comparatively weaker in tumors, their difference was minimal and difficult to discern. CONCLUSIONS Beta-catenin nuclear location could be considered as a paraneoplastic pattern which is considerably tumor-related. ERas may be a potential biomarker for gastric cancer, but advanced studies are wanted. GKN2 reduction is indiscernible by immunostaining.

Abstract
BACKGROUND E-cadherin/catenin complexes exert a role in cell adhesion. β-catenin is a key player in Wnt signaling pathway in gastric cancer. P53 is a tumor suppressor gene which also regulates apoptosis. We assessed the expression of E-cadherin, β-catenin and p53 in gastric adenocarcinoma, and their correlations with clinicopathological features. METHODS Fifty six formalin-fixed, paraffin-embedded archival specimens of gastric adenocarcinoma were randomly included as cases. Adjacent tumor-free gastric mucosa of different premalignant stages was obtained from the cases. Immunohistochemical staining was performed to assess E-cadherin, β-catenin and p53 expression. RESULTS All chronic atrophic gastritis and intestinal metaplasia revealed normal membranous staining. Only one patient with dysplasia had abnormal expression of E-cadherin and β-Catenin. Abnormal E-cadherin, β-catenin and p53 expression was found in 50%, 48.2% and 76.8% of cancer specimens respectively. Abnormal expression of E-cadherin was significantly correlated with aberrant β-catenin expression. Abnormal E-cadherin and β-catenin expression were significantly correlated with depth of tumor invasion and advanced gastric cancer (p < 0.05), lower degree of differentiation and diffused tumor type (p < 0.001). Node metastasis was not influenced by abnormal expression of E-cadherin and β-catenin. P53 was not associated with clinicopathological variables. CONCLUSIONS Abnormal expression of the E-cadherin and β-catenin were associated with each other and influenced by histogenesis of gastric cancer and malignant behavior of tumor but not significant in premalignant lesions. They are more frequent in diffuse type and associated with advanced gastric cancer. P53 alterations are more frequent in the Iranian population compared with others.

Abstract
Gastric cancer is of major importance world-wide being the second most common cause of cancer-related death in the world. According to Lauren's histological classification gastric cancer is divided in two groups, the better differentiated intestinal carcinomas and the poorly differentiated diffuse-type cancers. The genetic changes underlying the initiation and progression of gastric cancer are not well defined. Gastric carcinogenesis is a multistep process involving a number of genetic and epigenetic factors. Although it has been proposed that different genetic pathways exist for differentiated and undifferentiated carcinomas, the two histological subtypes of gastric cancer share some common genetic alterations. Currently, tumor histology and pathologic stage are the major prognostic variables used in the clinical practice for gastric cancer patients. However, it is known that tumors with similar morphology may differ in biological aggressiveness, prognosis and response to treatment. Molecular genetic analysis of gastric cancer revealed a number of associations of certain genetic changes with pathological features, tumor biological behavior and prognosis of gastric cancer patients, suggesting that these genetic abnormalities might play an important role in gastric tumorigenesis. Increasing evidence suggests that the molecular genetic changes could be helpful in the clinical setting, contributing to prognosis and management of patients. Regarding epigenetic events in gastric tumorigenesis, a number of methylating markers have been proposed for risk assessment, prognostic evaluation and as therapeutic targets. However, further research is required in order to systematically investigate the genetic changes in gastric cancer estimating also their usefulness in the clinical practice. A good understanding of the genetic changes underlying gastric carcinogenesis may provide new perspectives for prognosis and screening of high risk individuals. Some of the genetic alterations could definitely improve tumor classification and management of gastric cancer patients. Also, based on molecular data identified in gastric cancer novel therapeutics might help to improve the treatment of this disease.

Abstract
BACKGROUND We investigated whether an endogastric capsule (EC) may be a valuable tool for collecting DNA from exfoliated cells from the gastric mucosa and for carrying out an analysis of promoter methylation status of the E-cadherin (CDH1) gene in poorly differentiated, diffuse gastric cancer (DGC). MATERIAL AND METHODS Consecutive patients with a confirmed diagnosis of poorly differentiated DGC underwent collection of gastric juice by EC. Subjects without cancer and premalignant lesions were also accrued as controls. The samples of gastric juice were processed for DNA isolation and amplification. Then they were used for analysis of CDH1 promoter hypermethylation. RESULTS The procedure successfully allowed the analysis of CDH1 promoter hypermethylation in 20 patients and 14 controls. This pilot study showed feasibility of the procedure and a significantly different CDH1 promoter hypermethylation status between DGC patients and controls was detected. CONCLUSIONS The EC may represent an innovative and noninvasive tool for the analysis of a specific epigenetic change in DGC patients. Our findings deserve additional studies as this method may represent a cost-effective tool for early detection of sporadic as well as hereditary DGC in CDH1 germline mutations carriers.

Abstract
BACKGROUND Aberrant methylation of some cancer-related genes has been reported to correlate with sensitivity to chemotherapeutic agents. The present study was designed to determine whether DNA methylation in six cancer-related genes affects recurrence of gastric cancer in patients who received 5-fluorouracil-based adjuvant chemotherapy. METHODS The methylation status of six genes, MGMT, CHFR, hMLH1, p16INK4a, E-cadherin, and Runx3, was analyzed in 56 surgically resected gastric cancer tissue specimens by methylation-specific polymerase chain reaction. Of the 56 patients who underwent surgical resection, 38 received 5-fluorouracil (5-FU)-based adjuvant chemotherapy postoperatively (adjuvant group), whereas the other 18 (32%) did not (surgery group). RESULTS There were no significant differences between the two groups with respect to sex, cancer differentiation, depth of tumor invasion, lymph node metastasis, lymphatic invasion, vascular invasion and tumor stage. Among the genes, methylation of p16INK4a showed a significant correlation with longer survival in the 38 patients of the adjuvant group, but not in the 18 patients of the surgery group. A multivariate analysis identified p16INK4a methylation to be an independent factor predicting a longer recurrence-free period under 5-FU-based adjuvant chemotherapy. CONCLUSIONS The present study demonstrated for the first time that gastric cancer patients with p16INK4a methylation specifically benefit from 5-FU-based adjuvant chemotherapy.
