I read it selectively initiates apoptosis based on that protein and only affects cancer cells but that might have been relayed incorrectly Edit: exactly -> "It was created to target a specific variant of PCNA found only in cancer cells. This protein is crucial in the body for DNA repair, but targeting it was difficult because of its role in healthy cells. By going after only the variant, it may be possible to selectively target only cancer cells" From Wikipedia
