Abstract Animals rely on nervous systems to cope with environmental variability, whereas plants are characterized by lack of nervous system but still have evolved systemic communication systems through signaling molecules that trigger long-distance defense signaling events when encountered with environmental challenges

Cancer cells were sensitive to GGsTop when grown in cystine-free with GSH-supplemented conditions, but this increased sensitivity was reversed when cells were provided with cysteinylglycine, the product of GGT-mediated GSH catabolism (Fig
