Editor's note
A cell-culture study in which SS-31 was the direct intervention and showed a consistent signal against radiation-induced senescence markers. Findings are mechanistic and preclinical, not evidence of clinical benefit in people.
Plain-language abstract
In cultured rat and human heart-muscle cells, the mitochondria-targeted peptide SS-31 reduced markers of radiation-induced cellular aging and oxidative stress.
