Aging is a process characterized by gradual metabolome remodeling, deceleration of the remodeling in late life and under conditions that extend lifespan, and a mortality-associated pattern of cumulative damage.

Metabolite analysis of plasma from enteric fever patients define signals of organism specific host–pathogen interactions and provides opportunities for new diagnostics.

Young defense metabolites are often believed to be solely outputs but evidence suggests that they can regulate ancient signaling pathways.

Activity-guided fractionation identifies the first bacterial metabolite that potently induces a prion in nature.

The dual function of an ancient prokaryotic enzyme, which is linked to specific metabolite signals, may have been the evolutionary driving force behind its dual localization in eukaryotes.

Profiling of fibroblasts across mammals captures differences in longevity at the level of global gene expression and metabolite levels and reveals pathways that define these differences.

Metabolite mediates communication between stem cells and influences stem cell maintenance.

Interactions between fungal and bacterial microbiome members alter Drosophila melanogaster's chemical environment, affecting host behavior and survival.

Legionella pneumophila can be inhibited by its own antimicrobial, HGA (homogentisic acid), but its density-dependent resistance to HGA restricts the potential for self-harm.

The RNA-binding protein MSI1, which is required for stem cell and cancer cell proliferation in the brain and epithelial tissues, also directly senses the concentration of long non-esterified omega-9 fatty acids.
