The roles of specific microbial metabolites in aging remains understudied. Here we examine the microbiome’s contribution to the metabolic profile in aged mice. Fecal samples were collected from 8-week-old (young) and 18-month-old (aged) female Swiss-Webster mice raised conventionally (Conv) ...

Aging has shown close link to shifts in the skin microbiome in population cohort study. However, how variations in microbial communities relate to divergent skin aging within individuals of the same chronological ages remains unclear. In this study, we performed phenotypic, metabolomic and metage...

INTRODUCTION: The absolute quantitation of lipids at the lipidome-wide scale is a challenge but plays an important role in the comprehensive study of lipid metabolism.

OBJECTIVES: We aim to develop a high-throughput quantitative lipidomics approach to enab...

The complexity of the aging process, encompassing numerous organs and systems, poses a significant challenge in identifying and targeting key factors that drive age-related decline. The multi-organ synchronous molecular intricacies underlying natural aging remain elusive. Here we presented a data...

The incidence of intestinal diseases increases with age, but the regulators of gut aging and the molecules linking gut aging and diseases remain largely unknown. By profiling the transcriptome, proteome, phosphoproteome and metabolome of 104 Macaca fascicularis large intestinal tissues, ...

Emerging evidence suggests a significant role of gut microbiome in bone health. Aging is well recognized as a crucial factor influencing the gut microbiome. In this study, we investigated whether age-dependent microbial change contributes to age-related bone loss in CB6F1 mice. The bone phenotype...

Caloric restriction (CR) delays aging-related hallmarks in various organisms by slowing growth and development while enhancing metabolic homeostasis. However, desirable diets that harness the metabolic benefits of CR without imposing food intake restrictions remain elusive. Here we evaluated the ...

INTRODUCTION: The absolute quantitation of lipids at the lipidome-wide scale is a challenge but plays an important role in the comprehensive study of lipid metabolism.

OBJECTIVES: We aim to develop a high-throughput quantitative lipidomics approach to enab...

System-wide metabolic homeostasis is crucial for maintaining physiological functions of living organisms. Stable-isotope tracing metabolomics allows to unravel metabolic activity quantitatively by measuring the isotopically labeled metabolites, but has been largely restricted by coverage. Yet, de...
