Longevity Papers 2025-10-19

In this episode of Longevity Papers, we critically analyze five research papers from the week of October 13-19, 2025, curated from longevitypapers.com: 1) Mutation-Agnostic Base Editing of the Progerin Farnesylation Site Rescues Hutchinson-Gilford Progeria Syndrome Phenotypes in Neuromuscular Organoids (Kim et al., Seoul National University, October 16, 2025, bioRxiv, https://www.biorxiv.org/content/10.1101/2025.10.16.682736v1 ) - We examine the FATE platform for treating progeria through mutation-agnostic base editing, discussing its potential and significant translation challenges including organoid model limitations and in vivo delivery obstacles. 2) Phenome-Wide Multi-Omics Integration Uncovers Distinct Archetypes of Human Aging (Li et al., October 14, 2025, arXiv, http://arxiv.org/abs/2510.12384v1 ) - We critically evaluate claims of distinct aging subtypes from multi-omics data, addressing concerns about false discovery rates and the fundamental challenge of distinguishing signal from noise in high-dimensional biological data. 3) A Population-scale Single-cell Spatial Transcriptomic Atlas of the Human Cortex (Han et al., Lingang Laboratory Shanghai, October 14, 2025, bioRxiv, https://www.biorxiv.org/content/10.1101/2025.10.13.681959v1 ) - We discuss this comprehensive brain atlas showing age-related neuronal vulnerability and glial activation, while noting its limitations as an observational study that cannot distinguish cause from consequence. 4) Chaperone-mediated autophagy regulates neuronal activity by sex-specific remodelling of the synaptic proteome (Khawaja et al., Albert Einstein College of Medicine, October 15, 2025, Nature Cell Biology, https://pubmed.ncbi.nlm.nih.gov/41087566/ ) - We explore how CMA activation restores synaptic function in aging models, highlighting the sex-specific effects and therapeutic potential while discussing translation challenges. 5) Accelerated Regeneration of Senescent Bone Injury through Age- and Sex-Independent Macrophage Polarization (Fukuda et al., Tokushima University, October 15, 2025, ACS Applied Materials and Interfaces, https://pubmed.ncbi.nlm.nih.gov/41091908/ ) - We examine phosphatidylserine liposomes for bone repair in aging, noting the age/sex-independent macrophage effects while questioning the broader applicability beyond orthopedic applications. We provide critical analysis of statistical limitations, experimental needs, and the reality that this represents a typical week where 95 percent of research is incremental rather than transformative for longevity biotech.
