MetabolomicsMetabolomic Signature of Early Vascular Aging (EVA) in Hypertension

Arterial stiffening is a hallmark of early vascular aging (EVA) syndrome and an independent predictor of cardiovascular morbidity and mortality. In this case-control study we sought to identify plasma metabolites associated with EVA syndrome in the setting of hypertension. An untargeted metabolom...

MetabolomicsAbsolute quantitative lipidomics reveals lipidome-wide alterations in aging brain (Mouse brain NEG UPLC-MS assay)

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...

MetabolomicsUridine restores oocyte quality and mitigates female reproductive aging by inhibition of ferroptosis in mice

Advanced maternal age is a key factor in female infertility, primarily due to declines in ovarian reserve and oocyte quality. However, the metabolic mechanisms underlying reproductive aging are still poorly understood. Here, we show that uridine levels in the plasma and ovaries of aged mice are s...

MetabolomicsLocal and systemic metabolic alterations in brain, plasma, and liver of rats in response to aging and ischemic stroke, as detected by nuclear magnetic resonance (NMR) spectroscopy
Cerebral ischemia and aging induce local and systemic effects, and impact severity of stroke outcome. We performed comprehensive metabolic profiling to detect metabolites in brain, plasma, and liver as a function of aging and ischemia/reperfusion (IR). Ischemic stroke was induced by middle cerebral ...

MetabolomicsPEROXISOMAL-MITOCHONDRIAL INTERPLAY ALTERATIONS IN SKELETAL MUSCLE RESULT IN EARLY-ONSET SARCOPENIA

Adjustments in muscle mass and metabolic demand are crucial for regulating whole-body metabolism, locomotion, eating, and respiration. Therefore, skeletal muscle is a central influencer of several human diseases. Muscle dysfunction correlates with the onset and progression of several metabolic di...

TranscriptomicsAccumulating mitochondrial DNA mutations drive premature hematopoietic aging phenotypes molecularly distinct from physiologic stem cell aging
Somatic stem cells mediate tissue maintenance for the lifetime of an organism. Despite the well-established longevity that is a prerequisite for such function, accumulating data argue for compromised stem cell function with age. Identifying the mechanisms underlying age-dependent stem cell dysfuncti...

ProteomicsTMT-labeled quantitative protein profiling of hippocampus during human aging
Human hippocampus is one of the critical brain regions affected by aging. However, a fully understanding of aging-related changes in protein profiles in human hippocampus has not been well described, especially for the Chinese population. With the newly founded human brain bank in Chinese Academy of...

TranscriptomicsImpact of aging on cell-to-cell transcriptional variability during immune stimulation
We explored how aging impacts transcriptional dynamics using single-cell RNA-sequencing to profile hundreds of CD4+ T cells from young and old mice from two divergent species. In young animals, immunological challenge drives a conserved transcriptomic switch from highly variable to tightly regulated...
