中文摘要:
      摘 要:组蛋白翻译后修饰作为表观遗传调控的主要机制,可在DNA序列不改变的情况下,以共价键的方式在组蛋白特异位点添加小分子化学基团,如乙酰化、甲基化和磷酸化等来调节可遗传基因表达。这些修饰构成组蛋白密码,实时调控染色质的开放程度,从而影响蛋白质的结构、功能、活性以及稳定性。乳酸化、2-羟基异丁酰化等一系列新型组蛋白翻译后修饰的发现进一步增加了组蛋白密码表观遗传调控的复杂性,而组蛋白以及各种修饰酶的异常改变可通过诱导表观遗传和转录组促进肿瘤的发生。全文着重概括了组蛋白乳酸化和2-羟基异丁酰化修饰及其修饰酶的发现,并阐述了这两种修饰与肿瘤之间的关联,旨在强调这些新型修饰的深入研究在探索肿瘤的发病机制及治疗中起到重要作用。
英文摘要:
      Abstract: As a major mechanism of epigenetic regulation, post-translational modification of histones can regulate heritable gene expression by adding small molecule chemical groups through acetylation, methylation or phosphorylation, to histone-specific sites by covalent bonding without altering the DNA sequence. These modifications constitute the histone code, which regulates chromatin opening in real time, thereby affecting protein structure, function, activity, and stability. The discovery of a series of novel histone modifications, such as lactylation and 2-hydroxyisobutyrylation, has further increased the complexity of the epigenetic regulation of the histone code, and aberrant alterations in histones and various modifying enzymes can promote tumorigenesis by inducing the epigenetic and transcriptome. This paper summarizes the discovery of histone lactylation and 2-hydroxyisobutyrylation modifications and related enzymes, the association between these two modifications and tumorigenesis. The in-depth study of these novel modifications may be conducive to exploring the pathogenesis and treatment of cancer.
