摘要
Dear Editor,Recent studies from us and others have deciphered the clinical relevance of a variety of oncohistones1 in different diseases.The H3K27M and H3K36M mutant histones exert dominant-negative effects on methylation levels of histone H3K27 and H3K36 on wildtype histone protein in pediatric brain cancers2–4 and chondroblastoma,5,6 respectively.In contrast to H3K27M and H3K36M that act in trans to cause global reduction of methylation at the respective residues,the H3G34 mutations,including H3G34V/R and H3G34W/L found in pediatric high-grade glioma and giant cell tumor of the bone,affect the H3K36 methylation in cis and alter the H3K36 methylation on the nucleosome containing the H3G34 mutation(s).
