Schizophrenia, influenced by genetic and environmental factors, may involve epigenetic alterations, notably histone modifications, in its pathogenesis. This review summarizes various histone modifications including acetylation, methylation, phosphorylation, ubiquitination, serotonylation, lactylation, palmitoylation, and dopaminylation, and their implications in schizophrenia. Current research predominantly focuses on histone acetylation and methylation, though other modifications also play significant roles. These modifications are crucial in regulating transcription through chromatin remodeling, which is vital for understanding schizophrenia's development. For instance, histone acetylation enhances transcriptional efficiency by loosening chromatin, while increased histone methyltransferase activity on H3K9 and altered histone phosphorylation, which reduces DNA affinity and destabilizes chromatin structure, are significant markers of schizophrenia.
精神分裂症受遗传和环境因素的影响,其发病机制可能涉及表观遗传改变,特别是组蛋白修饰。本综述总结了各种组蛋白修饰,包括乙酰化、甲基化、磷酸化、泛素化、血清素化、乳酰化、棕榈酰化和多巴胺化,及其在精神分裂症中的意义。目前的研究主要集中在组蛋白乙酰化和甲基化上,但其他修饰也起着重要作用。这些修饰在通过染色质重塑调节转录中至关重要,这对于理解精神分裂症的发展至关重要。例如,组蛋白乙酰化通过松弛染色质来增强转录效率,而 H3K9 上组蛋白甲基转移酶活性的增加和组蛋白磷酸化的改变,降低了 DNA 亲和力并破坏了染色质结构,这些都是精神分裂症的重要标志物。
