This 2018 commentary challenges the binary classification of microbes as strictly beneficial or harmful, proposing that microbial roles are highly context-dependent. Using Akkermansia muciniphila as a case study, the authors illustrate how a bacterium commonly linked to metabolic health can also be associated with disease under certain conditions. The article
This comprehensive review highlights a significant global increase in early-onset cancers (diagnosed before age 50), including breast, colorectal, endometrial, and pancreatic cancers. While improved screening contributes to some cases, a genuine rise is attributed to early-life exposures such as dietary changes, obesity, sedentary lifestyles, environmental toxins, and microbiome alterations. The
This 2023 case-control study investigated the relationship between oral antibiotic use in adulthood and the risk of early-onset colorectal cancer (CRC) using data from UK primary care records between 1999 and 2011. Among 7,903 CRC cases (445 diagnosed before age 50) and 30,418 controls, antibiotic exposure was associated with a
This review article examines the potential of fecal microbiota transplantation (FMT) as a treatment for irritable bowel syndrome (IBS), a prevalent gastrointestinal disorder affecting approximately 11.2% of the global adult population. IBS is characterized by symptoms such as abdominal pain, bloating, and altered bowel habits, and is associated with dysbiosis—an
This study investigates the potential therapeutic effects of magnesium orotate in modulating the microbiome-gut-brain axis in individuals with gastrointestinal (GI) functional disorders and comorbid psychological symptoms, such as anxiety and depression. The cohort study involving 150 participants found that magnesium orotate improved both GI symptoms and psychological distress, suggesting a
This 2020 review article published in F1000Research (DOI: 10.12688/f1000research.20510.1, PMID: 32051759) discusses the role of zonulin-mediated gut permeability in the development of chronic inflammatory diseases (CIDs) such as autoimmune disorders, metabolic diseases, and cancer. Zonulin, a protein that regulates gut permeability, is implicated in the pathogenesis of CIDs due to
This 2015 observational study published in Cell Reports (PMID: 26321641) examined how aging in Drosophila melanogaster (fruit flies) affects gut microbiota and intestinal barrier function. Researchers found that aging flies experienced a notable shift in gut microbiota composition, particularly an expansion of Gammaproteobacteria, which preceded and predicted intestinal barrier dysfunction.
