Hepatocellular carcinoma (HCC) development is characterized by the presence of epigenetic alterations, including promoter DNA hypermethylation and post-translational modifications of histone, which profoundly affect expression of a wide repertoire of genes critical for cancer development. Emerging data suggest that deregulation of polycomb group (PcG) proteins, which are key chromatin modifiers repressing gene transcription during developmental stage, plays a causative role in oncogenesis. PcG proteins assemble into polycomb repressive complex 1 (PRC1) and polycomb repressive complex 2 (PRC2) to impose the histone H3 lysine 27 trimethylation (H3K27me3) modification for repression. In this review, we will first recapitulate the mechanisms of two key epigenetic pathways: DNA methylation and histone modifications. Specifically, we will focus our discussion on the molecular roles of PcG proteins. Next, we will highlight recent findings on PcG proteins, their clinicopathological implication and their downstream molecular consequence in hepatocarcinogenesis. Last but not least, we will consider the therapeutic potential of targeting enhancer of zeste homolog 2 (EZH2) as a possible treatment for HCC. Improving our understanding on the roles of PcG proteins in hepatocarcinogenesis can benefit the development of epigenetic-based therapy.

The mammalian MOF (male absent on the first), a member of the MYST (MOZ, YBF2, SAS2, and Tip60) family of histone acetyltransferases (HATs), is the major enzyme that catalyzes the acetylation of histone H4 on lysine 16. Acetylation of K16 is a prevalent mark associated with chromatin decondensation. MOF has recently been shown to play an essential role in maintaining normal cell functions. In this study, we discuss the important roles of MOF in DNA damage repair, apoptosis, and tumorigenesis. We also analyze the role of MOF as a key regulator of the core transcriptional network of embryonic stem cells.

Fruit ripening is a complex developmental process made up of genetically programmed physiological and biochemical activities. It culminates in desirable changes in the structural and textural properties and is governed by a complex regulatory network. Much is known about ethylene, one of the most important metabolites promoting the ripening of climacteric fruits. However, the dynamic interplay between phytohormones also plays an important part. Additional regulatory factors such as transcription factors (TFs) and epigenetic modifications also play vital role in the regulation of climacteric fruit ripening. Here, we review and evaluate the complex regulatory network comprising interactions between hormones and the action of TFs and epigenetic modifications during climacteric fruit ripening.

当下新型冠状病毒肺炎(COVID-19)的国际大流行促使全球科学家努力尝试揭秘新冠病毒HCoV-19的生物学特性。质谱分析(MS)发现,在HCoV-19 S蛋白的21个潜在糖基化修饰位点中,有20个位点完全被N-糖链占据,其糖型以低聚甘露糖为主。人血管紧张素转换酶2(hACE2)的7个糖基化位点完全被复合型N-糖链占据。然而,糖基化修饰并不能直接影响HCoV-19 S蛋白与hACE2之间的结合亲和力。另外,我们还发现了S蛋白和hACE2的多个甲基化修饰位点,以及hACE2的多个羟脯氨酸修饰位点。通过在最近发表的冷冻电镜(cryo-EM)结构的基础上加入N-糖链和蛋白质翻译后修饰(PTM),我们构建了HCoV-19 S蛋白和hACE2的精细结构模型。本研究揭示的HCoV-19 S蛋白和hACE2的PTM及糖基化图谱为研究病毒的宿主黏附、免疫反应,以及相关药物和疫苗的研发提供了更多的蛋白质结构细节。
