Histone H2B Mutations in Cancer

Abstract: Oncohistones have emerged as a new area in cancer epigenetics research. Recent efforts to catalogue histone mutations in cancer patients have revealed thousands of histone mutations across different types of cancer. In contrast to previously identified oncohistones (H3K27M, H3G34V/R, and H3K36M), where the mutations occur on the tail domain and affect histone post-translational modifications, the majority of the newly identified mutations are located within the histone fold domain and affect gene expression vi… Show more

“…While genomic alterations that support oncogenic growth have been identified in histone H1 ( Yusufova et al 2021 ) and histone H2B genes ( Kang et al 2021 ; Wan and Chan 2021 ), most studies have focused on the histone H3 genes ( Nacev et al 2019 ), in which typically 1 mutation is identified amongst the 15 genes, or 30 alleles, encoding H3 in the human genome. Oncogenic H3 mutations usually cluster in either of 2 genes encoding the H3 variant H3.3, which is the most evolutionarily conserved histone H3 variant ( Nacev et al 2019 ).…”

“…Modificações de histona e suas regulações na expressão gênicaNas células eucarióticas, o DNA é compactado em cromatina no núcleo. O núcleo básico da cromatina chama-se nucleossomo (Figura 3) e contém cerca de 146 pares de bases de DNA em torno de um octâmero de histonas, formado por um tetrâmero H2 (H2A e H2B) e dois dímeros H3 e H4 (Figura 3) 20. Histonas são proteínas que interagem com o DNA e possibilitam a sua compactação, servindo como elementos de controle de sua disponibilidade.…”
