Cover paper: Senescent characteristics of human corneal endothelial cells upon UV-A exposure

Researchers investigate senescence phenotypes of human corneal endothelial cells upon treatment with ultraviolet (UV)-A. Cells exhibit enlarged morphology, increased β-galactosidase activity and decreased proliferation. UV-A-induced senescent cells show similar gene expression profiles to ionizing radiation (IR)-induced cells.
