In the article by Kiziltepe et al entitled “JS-K, a GST-activated nitric oxide generator, induces DNA double-strand breaks, activates DNA damage response pathways, and induces apoptosis in vitro and in vivo in human multiple myeloma cells,” which appeared in the July 15, 2007, issue of Blood (Volume 110:709–718), several figures contained incorrect symbols. Figures 2C, 4C,D, 5A,C,D, and 6A all contain right-pointing hands that should have been asterisks. Each single hand represents a single asterisk, and each double hand represents 2 asterisks.
