Tissue-specific aging-a new paradigm based on transcriptional insights from select model systems and humans.

Tissue-specific aging patterns are revealed through transcriptomic analysis across multiple model systems and humans, indicating that each tissue ages differently.

• Why it matters: Understanding tissue-specific aging is crucial because aging processes vary between tissues, affecting health and disease outcomes, and current knowledge gaps hinder targeted interventions.
• What they did: The study uses bulk tissue and single-cell transcriptomes from C. elegans, Drosophila, mice, and humans to identify candidate genes and mechanisms driving tissue-specific aging changes.
• The result: This approach may expand the identification of aging-related genes and mechanisms, facilitating the development of diagnostics and therapies to improve human health span.
