Abstract
BACKGROUND/AIMS The rate of gastric cancer (GC) after Helicobacter pylori eradication has gradually increased; therefore, we investigate the clinicopathological features of GC following eradication in comparison with those of GC with H. pylori infection. METHODS This study included 50 subjects with GC after eradication (GCE) and 151 patients with GC with H. pylori infection (GCI). Clinicopathological factors were assessed. The manifestation of GC was further evaluated using immunohistochemical analysis and in situ hybridization. RESULTS Macroscopic analysis revealed a significantly higher ratio of depressed type /elevated type in the GCE compared with the GCI (30/19 vs. 61/77, p = 0.041). The gastric phenotype was more common in the GCE compared with the GCI, and the proportion of CDX2-positive cases was lower in the GCE (8 out of 18; 44.4%) compared with the GCI (18 out of 19; 94.7%; p = 0.00082). Ki-67 labeling index was significantly lower in the GCE (32.03 ± 22.15) compared with the GCI (79.20 ± 14.87, p < 0.0001). No patient in the GCE showed evidence of Epstein-Barr virus infection. CONCLUSION The clinicopathological characteristics of GC following H. pylori eradication differ from those of GC in patients with H. pylori infection in terms of morphology, mucin phenotype, and proliferation rate.

Abstract
Composed of trillions of individual microbes, the human gut microbiota has adapted to the uniquely diverse environments found in the human intestine. Quickly responding to the variances in the ingested food, the microbiota interacts with the host via reciprocal biochemical signaling to coordinate the exchange of nutrients and proper immune function. Host and microbiota function as a unit which guards its balance against invasion by potential pathogens and which undergoes natural selection. Disturbance of the microbiota composition, or dysbiosis, is often associated with human disease, indicating that, while there seems to be no unique optimal composition of the gut microbiota, a balanced community is crucial for human health. Emerging knowledge of the ecology of the microbiota-host synergy will have an impact on how we implement antibiotic treatment in therapeutics and prophylaxis and how we will consider alternative strategies of global remodeling of the microbiota such as fecal transplants. Here we examine the microbiota-human host relationship from the perspective of the microbial community dynamics.

MET4 expression predicts poor prognosis of gastric cancers with Helicobacter pylori infection. Cancer Sci 2017; 108:322-330. [PMID: 28012218 PMCID: PMC5378289 DOI: 10.1111/cas.13146] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Revised: 12/08/2016] [Accepted: 12/17/2016] [Indexed: 02/06/2023] Open
Abstract
The role of HGF/SF‐MET signaling is important in cancer progression, but its relation with Helicobacter pylori‐positive gastric cancers remains to be elucidated. In total, 201 patients with primary gastric carcinoma who underwent curative or debulking resection without preoperative chemotherapy were studied. MET4 and anti‐HGF/SF mAbs were used for immunohistochemical analysis. Survival of gastric cancer patients was estimated by Kaplan–Meier method and compared with log‐rank. Cox proportional hazards models were fit to determine the independent association of MET‐staining status with outcome. The effect of live H. pylori bacteria on cell signaling and biological behaviors was evaluated using gastric cancer cell lines. MET4‐positive gastric cancers showed poorer prognosis than MET4‐negative cases (overall survival, P = 0.02; relapse‐free survival, P = 0.06). Positive staining for MET4 was also a statistically significant factor to predict poor prognosis in H. pylori‐positive cases (overall survival, P < 0.01; relapse‐free survival, P = 0.01) but not in H. pylori‐negative cases. Gastric cancers positively stained with both HGF/SF and MET4 showed a tendency of the worst prognosis. Stimulation of MET‐positive gastric cancer cells with live H. pylori bacteria directly upregulated MET phosphorylation and activated MET downstream signals such as p44/42MAPK and Akt, conferring cell proliferation and anti‐apoptotic activity. In conclusion, positive staining for MET4 was useful for predicting poor prognosis of gastric cancers with H. pylori infection. Helicobacter pylori stimulated MET‐positive gastric cancers and activated downstream signaling, thereby promoting cancer proliferation and anti‐apoptotic activity. These results support the importance of H. pylori elimination from gastric epithelial surface in clinical therapy.
