A cDNA for purpurin, a secreted 20,000 dalton neural retina cell adhesion and survival protein, has been sequenced and expressed in mammalian cells. Purpurin mRNA is found in both embryonic and adult retina, but not the brain, heart, or liver.

Purpurin (1,2,4-trihydroxy-9,10-anthraquinone) is a naturally occurring anthraquinone pigment found in species of madder root. We have found that the presence of purpurin in bacterial mutagenicity assays is responsible for a marked inhibition of mutagenicity induced by food-derived heterocyclic amines. Purpurin

Chronic toxicity and tumorigenicity of purpurin, a natural hydroxyanthraquinone, was examined in two groups of male F344 rats. One group was given a basal diet mixed with purpurin at a concentration of 1% throughout the experiment (520 days). Another group
