Summary: This study reveals that certain genetic variants associated with Helicobacter pylori infection can increase the risk of gastric cancer. Individuals carrying these genetic variants and infected with H. pylori have an even higher risk of developing gastric cancer.

Summary: This review summarizes the oxidative stress response triggered by Helicobacter pylori (HP) in the gastric mucosa and the subsequent signaling pathways. The findings are expected to help in the formulation of new targeted drugs for preventing the occurrence of early gastric cancer and its progression to middle and advanced cancer.

Summary: Genetic analysis and culturing techniques for gastric non-Helicobacter pylori Helicobacter (NHPH) are advancing, with NHPH reported to accompany certain gastric conditions. A study on Korean gastric cancer patients found a low percentage positive for NHPH, suggesting it may play a role in gastric cancer development, albeit with lower pathogenicity compared to H. pylori.

Summary: This study evaluated humoral responses to a nearly complete H. pylori immunoproteome among GC cases and controls, finding higher prevalence of certain antibodies in controls and lower seroprevalence in GC cases, suggesting immune protection and potential changes in specific proteins.

Summary: Stomach cancer is a leading cause of cancer death, primarily caused by Helicobacter pylori infection, which induces inflammation and DNA damage. 2-hydroxybenzylamine (2-HOBA), derived from buckwheat seeds, is effective in reducing gastritis, gastric dysplasia, and carcinogenesis caused by H. pylori infection in mice and gastric epithelial cells.

Summary: Refractory Helicobacter pylori infection leads to significant alterations in gastric microbiota, inhibiting the growth of beneficial Lactobacillus. Patients with refractory H. pylori infection may be more prone to developing gastric cancer.

Summary: This study reveals that gastric non-Helicobacter pylori Helicobacter (NHPH) species naturally associated with animals are linked with gastric disease in human patients. The findings suggest that routine PCR testing for zoonotic gastric NHPHs should be conducted on patients with gastric complaints to diagnose potential pathogens.

Summary: Extracellular vesicles are important in host-pathogen interactions, playing a role in modulating inflammatory responses and promoting disease development. Both EVs from cells infected with H. pylori and H. pylori-OMVs are involved in the development of gastric cancer.

Summary: This study elucidates a novel mechanism of oxidative stress regulation by phosphorylated Siah2 in H. pylori-infected gastric epithelial cancer cells. Phosphorylation of Siah2 enhances the generation of reactive oxygen species (ROS) induced by H. pylori and leads to the degradation of the antioxidant protein GRP78. Surprisingly, cells expressing Siah2 with a phospho-null mutation have lower levels of cellular GRP78 but release more GRP78 and accumulate higher levels of ROS.

Summary: Helicobacter pylori (H. pylori) infection is a common cause of gastric disease, but the increase in antibiotic resistance has made it challenging to eradicate. The stomach has a unique microecology that can have positive, negative, or neutral effects on microbial fitness and function. This article reviews the imbalance of gastric microecology and its relationship with H. pylori, as well as potential methods for modulating gastric microecology to facilitate H. pylori eradication, such as probiotics, prebiotics, postbiotics, synbiotics, and microbiota transplantation.

Summary: Gastric cancer is a major cause of cancer-related deaths globally, and its development is influenced by genetic predisposition, environmental factors, and Helicobacter pylori infection. Matrix metalloproteinases (MMPs) play an active role in the progression of gastric cancer, with bacterial dependence being less significant in later stages.

Summary: Infection with H. pylori triggers a robust cellular response in the host, potentially leading to gastric cancer. The regulation of cellular processes through ubiquitinylation mechanisms influences various pathologies including cancer, yet the exact impact of H. pylori on this process remains unclear.
