英國科學(xué)家在最新一期英國《自然—遺傳學(xué)》(Nature Genetics)雜志上發(fā)表論文說,,他們發(fā)現(xiàn)了一種名為UTX的基因,其變異后能夠引發(fā)多種癌癥,。
英國韋爾科姆基金會桑格研究所科學(xué)家說,,位于X染色體上的UTX基因與控制其他基因的開啟與關(guān)閉有關(guān)。在對患有某種腎癌的患者組織樣本進(jìn)行了大規(guī)?;蚝Y查后,,科學(xué)家發(fā)現(xiàn),變異的UTX基因可導(dǎo)致癌癥,。當(dāng)研究范圍擴(kuò)大到其他類型的癌癥后,,科學(xué)家又發(fā)現(xiàn),這種變異的UTX基因?qū)Χ喟l(fā)性骨髓瘤和食道癌都起作用,。
該項(xiàng)目的負(fù)責(zé)人之一安迪·富特雷爾說:“與很多癌癥基因不同的是,,變異的UTX基因似乎并不直接參與細(xì)胞分裂或細(xì)胞死亡,而是影響細(xì)胞的基本調(diào)節(jié),,從而引發(fā)癌癥,。”
富特雷爾表示,除了特定的一種腎癌外,10%的多發(fā)性骨髓瘤病例和約8%的食道癌病例與變異的UTX基因有關(guān),。(生物谷Bioon.com)

Somatically acquired epigenetic changes are present in many cancers. Epigenetic regulation is maintained via post-translational modifications of core histones. Here, we describe inactivating somatic mutations in the histone lysine demethylase gene UTX, pointing to histone H3 lysine methylation deregulation in multiple tumor types. UTX reintroduction into cancer cells with inactivating UTX mutations resulted in slowing of proliferation and marked transcriptional changes. These data identify UTX as a new human cancer gene.
