A cancer-promoting histone protein Mutations in the chromatin protein histone H3 are found in a number of pediatric cancers. The lysine-36–to–methionine (K36M) “oncohistone” mutation is seen in almost all chondroblastomas. Fang et al. show that the K36M mutant histones inhibit the normal methylation of this same residue in wild-type H3 histones. They do so by interfering with the enzymes that normally methylate this residue. The altered chromatin methylation patterns alter the expression of known cancer-related genes and impart cancer-related characteristics to the chondrocyte cells. Science , this issue p. 1344
Dynamic reprogramming of DNA methylation in SETD2-deregulated renal cell carcinoma
Key PointsThe NF-κB subunits p52 and RelB increase IRF4 promoter activity and expression in PTCL cells. A positive feedback loop involving CD30, NF-κB, and IRF4 drives PTCL cell proliferation and can be blocked by NF-κB inhibitors.
