Arising from L. Kruidenier et al.10.1038/nature11262 The recent publication1 of the first highly potent and specific inhibitor GSK-J1/J4 of the H3K27me3/me2-demethylases JMJD3/KDM6B and UTX/KDM6A provides a potential tool compound for this histone demethylase subfamily1. This inhibitor was used in tissue culture assays to conclude that the catalytic activities of the KDM6 proteins are required in inflammatory responses1; the generation of the inhibitor is intriguing, because it provides a strategy for generating sub-type-specific inhibitors of the 27-member Jumonji family and for the future treatment of various types of disease2,3,4,5,6. Here we show that the inhibitor is not specific for the H3K27me3/me2-demethylase subfamily in vitro and in tissue culture assays. Thus, the inhibitor cannot be used alone for drawing conclusions regarding the specific role of H3K27me3/me2-demethylase activity in biological processes or disease.
