title: The effect of 3-aminobenzamide on thymidine incorporation in ultra-violet irradiated chick pigment epithelium cells.
abstract: The addition of 3-aminobenzamide (3-AB) to cultures of chick embryo pigmented epithelium rescues these cells after high doses of ultraviolet treatment. The addition of 3-AB prevents cells from losing pre-formed protein and DNA and stimulates thymidine incorporation by the cells after ultraviolet irradiation. Since 3-AB is an inhibitor of poly (ADP) ribosylation, these observations support the conclusion that death of these cells after ultra-violet irradiation depends upon poly (ADP) ribosylation and may be an apoptotic response.
