Research indicates that specific bacteria and their metabolites can trigger genotoxicity, drive chronic inflammation, and alter the immune landscape within the tumor microenvironment. These microbial proces...

This review article examines the oral–gut microbiome axis, highlighting how the mouth serves as a primary gateway for microbes to influence the rest of the body. While physico-chemical barriers typically keep these two ecosystems distinct, oral bacteria can migrate to the intestines through the digestive or circulatory systems, especially when health is compromised. The authors explain how this mi...

This research introduces curatedMetagenomicData (cMD) 3, a massive, standardized resource containing over 22,000 human microbiome samples across 42 countries. By applying uniform processing to these diverse datasets, researchers identified specific microbial signatures linked to host factors like age, sex, and body mass index. The study also highlights consistent patterns of dysbiosis across 15 di...

The Health for Life in Singapore (HELIOS) Study is a sophisticated longitudinal research initiative designed to address the historic under-representation of Asian populations in genomic and clinical data. By profiling over 10,000 participants of Chinese, Indian, and Malay descent, researchers have created a comprehensive database that integrates lifestyle behaviors, environmental factors, and mult...

This research study presents a comprehensive proteomic analysis of human immune cells following acute physical activity. By comparing high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE), researchers discovered that intense movement triggers more significant rewiring of immune cell pathways related to activation and effector function.
