The probiotic impact of microbes on host metabolism and health depends on both host genetics and bacterial genomic variation. is the predominant human gut commensal emerging as a next-generation probiotic. Although this bacterium exhibits substantial intraspecies diversity, it is unclear whether genetically distinct strains might lead to functional differences in the gut microbiome.

Peripheral arterial chemoreceptors monitor the levels of arterial blood gases and adjust ventilation and perfusion to meet metabolic demands. These chemoreceptors are present in all vertebrates studied to date but have not been described fully in reptiles other than turtles. The goals of this study were to 1) identify functional chemosensory areas in the South American rattlesnake (Crotalus durissus) 2) determine the neurochemical content of putative chemosensory cells in these areas and 3) determine the role each area plays in ventilatory and cardiovascular control.

Background: HA14-1 is a small-molecule, stable B-cell lymphoma 2 (Bcl-2) antagonist that promotes apoptosis in malignant cells through an incompletely-defined mechanism of action. Bcl-2 and related anti-apoptotic proteins, such as B-cell lymphoma-extra-large [Bcl-XL]), are predominantly localized to the outer mitochondrial membrane, where they regulate cell death pathways. However, the notably short half-life of HA14-1 limits its potential therapeutic application.

Background: Mitochondrial dysfunction is increasingly recognized as a key factor in neurodegenerative diseases (NDDs), underscoring the therapeutic potential of targeting mitochondria-related genes. This study aimed to identify novel biomarkers and drug targets for these diseases through a comprehensive analysis that integrated genome-wide Mendelian randomization (MR) with genes associated with mitochondrial function.
Methods: Using existing publicly available genome-wide association studies (GWAS) summary statistics and comprehensive data on 1136 mitochondria-related genes, we initially identified a subset of genes related to mitochondrial function that exhibited significant associations with NDDs.
Potential roles of cigarette smoking on gut microbiota profile among Chinese men.

The Second Affiliated Hospital, School of Public Health, Zhejiang University School of Medicine, 388 Yuhangtang Road, Hangzhou, 310058, Zhejiang, China.
Background: Cigarette smoking is posited as a potential factor in disrupting the balance of the human gut microbiota. However, existing studies with limited sample size have yielded inconclusive results.
Methods: Here, we assessed the association between cigarette smoking and gut microbial profile among Chinese males from four independent studies (N total = 3308).
