Summary

Vadim Gladyshev, a professor at Harvard Medical School, presents a comprehensive overview of his laboratory’s research on aging at the 13th Aging Research and Drug Discovery Meeting. He emphasizes that aging should be modeled as systemic biological states using multimodal, multispecies, and longitudinal data. The talk covers three key areas: measuring aging via various ‘clocks’ (epigenetic, transcriptomic, organ-specific), targeting aging through in silico drug screening and interventions, and understanding aging as a systemic process. He highlights a recent Nature paper on aging as a loss of developmental program, the transcriptomic clock tool ‘Taco’, and a bioRxiv study on heterochronic heart transplantation showing that young hearts age faster in old hosts while old hearts rejuvenate in young hosts. He also describes the development of ~50 organ-specific clocks, longitudinal tracking of biological age in UK Biobank, and a multimodal approach integrating omics and imaging. He concludes with three insights: diseases can be viewed as organ-specific aging, the need to shift from target discovery to biological state discovery, and the importance of learning from biological data rather than human interpretation.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk offers substantial value by presenting a coherent framework for aging research, supported by multiple large-scale studies and tools developed by the lab. Arguments are well-articulated: the idea that aging is a systemic accumulation of damage, that biological age can be measured and targeted, and that organ-specific aging underlies disease. The reasoning is logically structured, with concrete examples (e.g., drug screens identifying ouabain, heterochronic heart experiments) and transparent discussion of failures and limitations (e.g., no correlation between lab interventions and natural longevity differences). The presentation is dense but clear, making a strong case for a paradigm shift in how aging is studied and treated.

Scientific Rigor, Source Quality, Title Accuracy

The scientific rigor is high: the speaker references multiple peer-reviewed publications (Nature, Nature Biotechnology, bioRxiv) and describes methodologies in detail (e.g., training clocks, validation in mice, use of UK Biobank). He openly discusses potential confounding factors, such as immune cell infiltration in heart transplant studies, and provides actionable tools for the community (Taco). The title accurately mirrors the content: measuring (clocks), targeting (screens), and understanding (systemic models) aging. No comments were provided to analyze public reception.

Contribution & Novelties

This talk synthesizes the lab’s recent contributions: a Nature paper on aging as loss of development, a transcriptomic clock validated across species, the Taco tool for community use, organ-specific clocks, and a bioRxiv study on heterochronic heart transplantation. The original contribution lies in the systematic integration of multimodal data and the conceptual shift toward biological state modeling rather than single targets. The speaker proposes a new paradigm for aging research, emphasizing that diseases are manifestations of organ-specific aging and that interventions should be evaluated by their effect on biological states rather than on isolated molecules.

Pour aller plus loin :

  • Epigenetic clock — Related to Horvath’s clocks, foundational to the concept of biological age.
  • Biomarkers of aging — Overview of aging biomarkers, contextualizing the transcriptomic and other clocks.
  • Calorie restriction — An intervention mentioned as remodeling physiology, with known effects on lifespan.
