BACKGROUND Age-related cataract (ARC) is the leading cause of visual impairment worldwide, and α-crystallin (CRYAA) is the predominant structural protein involved in the maintenance of lens clarity and refractive properties. We previously demonstrated that CRYAA genes undergo epigenetic repression in the lens epithelia in ARC. We further analyze the underlying mechanism in the current study. ...

To assess more fully the risk to normal tissue exposed to accelerated heavy particles in the space program and during radiotherapy on earth, the cytopathological effects of a variety of doses of accelerated (570 MeV/amu) Argon (40Ar) ions on the rat lens were investigated. Time-course analyses of lenses exposed to a 1 Gy (100 rad)-dose revealed that the effects of the particles on mitotic index...

Oxidative stress has an important role in the degradation, oxidation, cross‑linking and aggregation of lens proteins, and can trigger lens epithelial cell apoptosis. To investigate the protective effect of chlorogenic acid (CGA) against hydrogen peroxide (H2O2)‑induced oxidative stress, human lens epithelial cells (hLECs) were exposed to various concentrations of H2O2 in the presence and absenc...
