Macroscopic to ultrastructural analyses identify the loss of myofibrils as the primary mediator of ageing‐ and disuse‐induced muscle fibre atrophy

open access: yesThe Journal of Physiology, Volume 604, Issue 20, Page 8523-8541, 15 October 2026.
Abstract figure legend Skeletal muscle structure was analysed at three levels in young vs. aged humans, and in young vs. aged mice subjected to unilateral hindlimb immobilization to model disuse. (1) Macroscopic: magnetic resonance imaging of the thigh (human) and wet mass of individual hindlimb muscles (mouse) revealed that both ageing and disuse ...

A Wrinkle in Time: Premature Aging in HGPS and RD [PDF]

open access: yes, 2008
The aging process can be accelerated by numerous cellular and molecular variables. Progeroid syndromes are one such example. The phenotypes of Hutchinson-Gilford Progeria Syndrome (HGPS) and Restrictive Dermopathy (RD) are both caused by an irregular ...

Hydrology and geochemistry of a Hawaiian geothermal system: HGP-A [PDF]

open access: yes, 1978
A water quality monitoring program of the Hawaii Geothermal Project well A (HGP-A) was conducted for downhole depth samples and continuous discharge samples in 1976 to 1977. The well water was slightly saline (about 5-10 percent ocean water) and nearly depleted of magnesium, but contained high concentrations of silica and sulfide.

LivAge: An Online Aging Clock for Murine Transcriptomic Age Estimation

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
We present LivAge, an online aging clock that estimates murine transcriptomic age from hepatic RNA‐seq data. Externally validated, it detects accelerated aging in progeroid models and quantifies the effect of geroprotective interventions, providing an accurate, accessible, and ready‐to‐use tool for aging research.

Temsirolimus does not impact DNA damage levels in HGPS cells.

open access: yes, 2016
(A) Immunohistochemistry of control (GMO3349C) and HGPS (HGPSFN003) cells either mock-treated or treated with 1.0 μM temsirolimus for a period of 9 days. Antibodies against γH2A.X and 53BP1 were used (n = 4). Scale bar: 20 μm. (B) Immunohistochemistry of

An alternative source of purine partially reverts the premature phenotype aging in HGPS-derived cells.

open access: yes, 2018
Effect of incubation with SAMe on the premature-aging phenotype of HGPS cell lines. MTT-based proliferation assay (A) showing that periodic addition of SAMe to the culture media at a final concentration of 10 μg/mL, have a significant (p-value≤ 0.05 ...

Comparative transcriptome analysis of Parkinson’s disease and Hutchinson-Gilford progeria syndrome reveals shared susceptible cellular network processes

open access: yesBMC Medical Genomics, 2020
Background Parkinson’s Disease (PD) and Hutchinson-Gilford Progeria Syndrome (HGPS) are two heterogeneous disorders, which both display molecular and clinical alterations associated with the aging process.

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

open access: yesAging 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 ...

Reductions in gammaH2AX response in HGPS cells are cell cycle dependent.

open access: yes, 2016
(A). Representative fluorescence images of gammaH2AX foci and BrdU staining in middle passage normal and HGPS fibroblasts after Dox treatment. G0/G1 and S phase were indicated by BrdU negative and positive staining respectively. Scale Bar: 5um.

An Overview of Hutchinson Gilford Progeria Syndrome (HGPS)

open access: yesBritish Journal of Medicine and Medical Research, 2015
Hutchinson Gilford Progeria Syndrome (HGPS) is a rare genetic disorder. The disorder is characterized by premature aging, generally leading to death. The purpose of this article is to review Hutchinson Gilford Progeria Syndrome and its characteristics.
