Dysbiosis of Gastric Mucosal Fungal Microbiota in the Gastric Cancer Microenvironment

Journal of Immunology Research, 2022
Background. Microbes have been shown to contribute to gastric cancer (GC), gastric bacteria and viruses are associated with gastric carcinogenesis. However, the relationship between gastric fungi and GC is still unclear. Our aim was to evaluate the gastric fungal microbiota in the GC microenvironment. Methods.

Leveraging existing 16S rRNA microbial data to identify diagnostic biomarker in Chinese patients with gastric cancer: a systematic meta-analysis

mSystems, 2023
Gastric cancer is the second most prevalent and deadly cancer in China. Microbiota play an important role in gastric tumorigenesis. However, the available microbial marker studies for gastric cancer do not have consistent results.

Helicobacter pylori Infection and Gastric Microbiota

Euroasian Journal of Hepato-Gastroenterology, 2020
Owing to its strong acid production, the stomach was known to be a bacteria-free organ for many years. On the other hand, the presence of Helicobacter pylori (H. pylori) and other acid-resistant microbiota that are to persist in the stomach challenged this. It is now recognized that the existence of H. pylori and non-H.

The Influence of Helicobacter pylori on Human Gastric and Gut Microbiota [PDF]

, 2023
Helicobacter pylori is a Gram-negative bacterium that is able to colonize the human stomach, whose high prevalence has a major impact on human health, due to its association with several gastric and extra-gastric disorders, including gastric cancer.

The role of microbiota in the development and treatment of gastric cancer

Frontiers in Oncology, 2023
The stomach was once considered a sterile organ until the discovery of Helicobacter pylori (HP). With the application of high-throughput sequencing technology and macrogenomics, researchers have identified fungi and fivemajor bacterial phyla within the ...

Microbiota and gastric diseases in 2022

Microbiota in Health and Disease, 2022
Helicobacter pylori is the most dominant and clinically relevant member of the human gastric microbiota that it may be considered a natural member of it as only a small proportion of H. pylori-colonized humans develop disease. At phylum level, the gastric microbiota is mainly comprised of Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria and ...
