The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, Volume 600, Issue 4, Page 418-438, February 2026.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Structure and stability of the lamin A tail domain and HGPS mutant [PDF]

open access: yes, 2011
Hutchinson–Gilford progeria syndrome (HGPS) is a premature aging syndrome caused by the expression and accumulation of a mutant form of lamin A, Δ50 lamin A.

Personalized Models of Biological Barriers and Their Diseases: Recent Progress with Organs‐On‐Chips

open access: yesAdvanced Biology, Volume 10, Issue 2, February 2026.
Buck and Bugter et al. explore the architectural diversity and physiological functions of human barrier systems and reveal how organ‐on‐chip platforms, particularly those integrating patient‐derived cells, are advancing barrier disease modeling. They highlight how emerging biological and technological advances can be used to bridge the gap between ...

Progeroid Syndrome and Mutation in LMNA Gene: Report of Two Cases from Iran [PDF]

open access: yesJournal of Kerman University of Medical Sciences, 2005
Two Iranian cases with very rare progeroid syndrome are reported. The first is a 24-year-old girl who has been healthy till her 13th birthday. From that time she has been suffering from a progressive generalized and multi-systemic illness.

A Novel Human Cellular System for Studying Normal Aging and for Anti‐Aging Discovery

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
This study introduces a human cellular aging model using placental trophoblasts (hTSC‐STBs) that mimics key aging features like senescence and genomic instability. It aligns with human tissue aging and responds to anti‐aging treatments, offering a scalable platform to screen potential therapies and bridge lab findings to clinical applications ...

Age-dependent changes of nuclear morphology are uncoupled from longevity in Caenorhabditis elegans IGF/insulin receptor daf-2 mutants [PDF]

open access: yes, 2016
Nuclear envelope (NE) architecture and aging have been associated since the discovery that certain human progeria diseases are due to perturbations in processing of lamin A protein, generating alterations in NE morphology. However, whether changes in the

Proximal Pulmonary Artery Stiffening as a Biomarker of Cardiopulmonary Aging

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Mouse models revealed age‐associated increased circumferential stiffness of the proximal pulmonary artery that was associated with reorientation of collagen and decreased function of the lung and right ventricle. Age‐related transcriptional changes were indicative of senescence, ECM turnover, TGFβ signaling, and altered intercellular signaling among ...
