Increasing the length of progerin's isoprenyl anchor does not worsen bone disease or survival in mice with Hutchinson-Gilford progeria syndrome

Journal of Lipid Research, 2009
Hutchinson-Gilford progeria syndrome (HGPS) is caused by the synthesis of a truncated prelamin A, commonly called progerin, that contains a carboxyl-terminal farnesyl lipid anchor.

European Consortium for Lipodystrophies consensus definition and classification framework for monogenic lipodystrophy

Journal of Internal Medicine, EarlyView.
Abstract Lipodystrophy comprises a heterogeneous group of disorders characterized by reduced adipose tissue often associated with severe metabolic complications. Lipodystrophy may be genetic, acquired, or secondary to medical therapies initiated for other conditions.

The Underexplored Mechanobiology of Lamin A Biogenesis and Homeostasis

Biology of the Cell, Volume 118, Issue 10, October 2026.
We highlight current evidence, unresolved questions, and future directions, proposing that mechanical regulation of lamin A biogenesis represents an underexplored dimension of lamin mechanobiology with broad implications for development, aging, laminopathies, and mechanically driven diseases. ABSTRACT Lamin A is a major contributor to nuclear mechanics

Dietary magnesium supplementation improves lifespan in a mouse model of progeria

EMBO Molecular Medicine, 2020
Aging is associated with redox imbalance according to the redox theory of aging. Consistently, a mouse model of premature aging (LmnaG609G/+) showed an increased level of mitochondrial reactive oxygen species (ROS) and a reduced basal antioxidant ...

Nucleic Acids as Emerging Regulators of Calcium Phosphate Biomineralization

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Calcium phosphate biomineralization has traditionally been considered a protein‐regulated process. This review highlights the emerging role of nucleic acids, which interact with mineral phases through adsorption, coprecipitation, and templating, thereby influencing crystal nucleation and growth.

Surviving the Nucleus Pulposus Desert: Next‐Generation Strategies for Intervertebral Disc Cell Therapy

JOR SPINE, Volume 9, Issue 3, September 2026.
ABSTRACTBackgroundLow back pain remains the leading cause of disability worldwide, with intervertebral disc degeneration representing a major biological contributor. Although cell‐based therapies have shown promise in preclinical models, clinical translation has yielded modest and inconsistent outcomes.

A multiparametric anti-aging CRISPR screen uncovers a role for BAF in protein synthesis regulation

Nature Communications
Progeria syndromes are very rare, incurable premature aging conditions recapitulating most aging features. Here, we report a whole genome, multiparametric CRISPR screen, identifying 43 genes that can rescue multiple cellular phenotypes associated with ...

High‐Content CRISPR Screening: Methods and Applications

MedComm, Volume 7, Issue 9, September 2026.
High‐content CRISPR screening represents a paradigm shift in functional genomics, moving beyond traditional survival‐based readouts to enable multidimensional mapping of genotype–phenotype relationships. This review systematically outlines the methodological evolution of this approach, detailing advances in perturbation modalities, delivery systems ...

Akkermansia muciniphila and Its Bioactive Derivatives: Emerging Regulators of Healthy Aging

Aging Cell, Volume 25, Issue 9, September 2026.
The beneficial gut bacterium Akkermansia muciniphila (AKK) declines with age but is enriched in healthy centenarians. Supplementation of AKK extends healthspan and alleviates age‐related decline through direct host–microbe interactions and its bioactive derivatives, which collectively enhance gut barrier integrity, restore metabolic homeostasis ...
