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...

Lifelong murine gene expression profiles in relation to chronological and biological aging in multiple organs Five tissues: Kidney, Liver, Lung, Spleen, Brain. Six timepoints: 13wks, 26 wks, 52wks, 78wks, 104wks, 130wks. One Genotype: C57Bl/6, 3 replicates
ORGANISM(S): Mus musculus 
Mesenchymal stromal cells (MSCs) are of high relevance for the regeneration of mesenchymal tissues such as bone and cartilage. The promising role of MSCs in cell-based therapies and tissue engineering appears to be limited due to a decline of their regenerative potential with increasing donor age, t...

Transcriptional Profile of Aging in C. elegans Whole-genome analysis of gene expression during chronological aging of the worm provides a rich database of age-specific changes in gene expression and represents one way to distinguish among these models. Using a rigorous statistical model with multip...
ORGANISM(S): Caenorhabditis elegans 
Skeletal muscle is a post-mitotic tissue that exhibits an extremely low turnover in the absence of disease or injury. At the same time, muscle possesses remarkable regenerative capacity mediated by satellite cells (SCs) that reside in close association with individual myofibers, underneath the fiber...
ORGANISM(S): Mus musculus 
We analyzed expression of 81 normal muscle samples from humans of varying ages, and have identified a molecular profile for aging consisting of 250 age-regulated genes. This molecular profile correlates not only with chronological age but also with a measure of physiological age. We compared the tra...
ORGANISM(S): Homo sapiens 
Unlike chronological age, biological age is a strong indicator of health of an individual. However, the molecular fingerprint associated with biological age is ill-defined. To define a high-resolution signature of biological age, we analyzed metabolome, circulating senescence-associated secretome (S...

Impaired extracellular matrix (ECM) remodeling is a hallmark of many chronic inflammatory disorders that can lead to cellular dysfunction, aging, and disease progression. The ECM of the aged heart and its effects on cardiac cells during chronological and pathological aging are poorly understood acro...
