表觀遺傳學(Epigenetics)是基因表達的可遺傳修飾 (heritable modifications),與 DNA 序列(DNA sequence)的變化無關。表觀遺傳修飾(Epigenetic modifications)主要發生在 DNA 或組蛋白八聚體(histone octamer)上。有幾種類型的表觀遺傳學修飾(epigenetics modifications),DNA-甲基轉移酶 (DNMT) 的 DNA 甲基化和組蛋白的共價修飾,例如乙醯化(acetylation)、甲基化(methylation)、磷酸化(phosphorylation)和泛素化(ubiquitination)。組蛋白乙醯轉移酶 (HAT) 的組蛋白乙醯化參與轉錄激活,而組蛋白去乙醯化酶 (HDAC) 的組蛋白去乙醯化與轉錄抑制(transcriptional repression)有關。組蛋白去甲基化(Histone demethylation)與賴氨酸特異性去甲基化酶 (lysine-specific demethylase , LSD) 和含有組蛋白去甲基化酶 (JHDM) 的 JmjC 結構域(JmjC domain)有關。
核小體(nucleosome)由四種組蛋白(H2A、H2B、H3 和 H4)組成,它們是染色質(chromatin)的主要組成部分。特定化學基團的添加和去除稱為表觀遺傳標記(epigenetic marks),它調節染色質結構並影響基因表達。此外,RNA 與抑制性染色質狀態(repressive chromatin state)的形成密切相關。
表觀遺傳(Epigenetic)機制在細胞水平上響應環境變化,從而影響細胞可塑性(plasticity)。染色質(Chromatin)和表觀遺傳調控(epigenetic regulation)在發育和應激反應期間的基因組編程中發揮重要作用,表觀遺傳學缺陷(defects in epigenetics)可導致癌症(cancer)、炎症(inflammation)和代謝紊亂(metabolic disorders)等。
EPZ-6438 | CAS#1403254-99-8 APExBIO 貨號A8221
EPZ-6438 是一種有效且具有生物活性的 EZH2 抑制劑,EZH2 是多梳抑制複合物 2 (polycomb repressive complex 2 , PRC2) 的催化亞基,可催化組蛋白 H3 (H3K27) 的賴氨酸 27 的甲基化,從而抑制含有人 PRC2 的野生型的活性EZH2 的抑制常數 Ki 值為 2.5 nM。 EPZ-6438 競爭性結合 EZH2 的 S-腺苷甲硫氨酸 (S-adenosylmethionine , SAM) 結合位點,也非競爭性結合肽或核小體底物的結合位點。 EPZ-6438 選擇性抑制 EZH2,選擇性比 EZH1 高 35 倍。研究結果表明,通過 EPZ-6438 介導的 EZH2 抑制對幾種癌症途徑的協同作用,EPZ-6438 在 MRT 模型中表現出顯著且持久的抗腫瘤活性。
