Buildup of GATA4 protein pushes cell into static state of senescence, a change linked to aging

BUILDING UP  Brain cells from older people (center) contained visibly greater amounts of the protein GATA4 (red) than brain cells from younger people (left). The chart compares the presence of the protein in young (blue) and old (red) cells. GATA4 plays a key role in switching on senescence, a cellular state linked with aging disorders.
