Propionic Acidemia: Gray Matter Disease Meets Subcortical Leukodystrophy

open access: yesJournal of Inherited Metabolic Disease, Volume 48, Issue 6, November 2025.
ABSTRACT Imaging literature on propionic acidemia (PA) is predominantly concerned with deep gray matter changes. In order to investigate the spectrum and patterns of MRI changes, 45 MRI scans of 13 patients (0.31–33.2 years) were systematically analyzed. Deep and cortical gray matter changes were associated with acute metabolic decompensation. Striatum

Age‐Associated Transcriptomic and Epigenetic Alterations in Mouse Hippocampus

open access: yesAging Cell, Volume 24, Issue 11, November 2025.
Single‐nucleus multiome sequencing of hippocampus reveals aging‐dependent changes in gene expression and chromatin accessibility. Chromatin alterations in synaptic genes often occur without corresponding expression changes, suggesting a “susceptible” chromatin state.

Brain DNA Methylation Atlas of AppNL‐G‐F Alzheimer's Disease Model Mice Across Age and Region Reveals Choline‐Induced Resilience

open access: yesAging Cell, Volume 24, Issue 11, November 2025.
Brain DNA methylation drives abnormal gene expression in AppNL‐G‐F mice. Perinatal choline supplementation may promote resilience to synaptic dysfunction through modulation of DNA methylation. ABSTRACT Alzheimer's disease (AD) is the most common type of dementia.

Muscle Cathepsin B Treatment Improves Behavioral and Neurogenic Deficits in a Mouse Model of Alzheimer's Disease

open access: yesAging Cell, Volume 24, Issue 11, November 2025.
Targeting muscle with Cathepsin B (Ctsb) to treat the AD mouse brain. In this study, an AAV‐vector‐mediated approach, utilized to express Ctsb in muscle, prevented mnemonic and neurogenic deficits and normalized hippocampal, muscle, and plasma proteomic profiles.

Organ‐Specific Dedifferentiation and Epigenetic Remodeling in In Vivo Reprogramming

open access: yesAging Cell, Volume 24, Issue 11, November 2025.
Transient in vivo expression of Yamanaka factors (OSKM) enhances regenerative competence and rejuvenation across multiple tissues. We highlight mechanistic links between injury‐induced dedifferentiation and OSKM reprogramming, while emphasizing safety challenges and the need for precise spatiotemporal control to enable clinical translation.
