背景说明
Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. H3.1 is enriched in PTMs associated with gene activation (K14 acetylation) and gene silencing (K9 dimethyla tion), suggesting that these mammalian H3 variants may, indeed, have separate biological functions [PMID: 16571659].

背景说明
组蛋白翻译后修饰,也称作“组蛋白密码”,通过调控染色质结构发挥作用,是表观遗传学的重要研究分支。组蛋白上的翻译后修饰包括乙酰化,甲基化,磷酸化和近年发现的一些新型酰化修饰。这些组蛋白修饰直接影响染色质和转录因子或其他表观调控子的结合,改变基因组的稳定性和基因转录等。组蛋白甲基化通常发生在核心组蛋白的赖氨酸和精氨酸侧链氨基上。组蛋白甲基化既可以促进也可以抑制基因转录,这取决于组蛋白甲基化是发生在赖氨酸还是发生在精氨酸上以及甲基化基团的个数(赖氨酸可以发生一、二、三甲基化,精氨酸可发生单、对称与非对称二甲化)。组蛋白赖氨酸甲基化通常发生在组蛋白H3第4,9,27,36,79和组蛋白H4的第20位赖氨酸上;精氨酸甲基化通常发生在组蛋白H3的第2,8,17,26和组蛋白H4第3位精氨酸上。蛋白甲基化酶(HMT)和组蛋白去甲基化酶(HDM)是甲基化修饰主要的调控因子。

生物活性 PXD101 is a novel hydroxamate-type inhibitor of histone deacetylase activity that inhibits histone deacetylase activity in HeLa cell extracts with an IC(50) of 27 nM and induces a concentration-dependent (0.2-5 micro M) increase in acetylation of histone H4 in tumor cell lines.[1]
In Vitro PXD101 is cytotoxic in vitro in a number of tumor cell lines with IC(50)s in the range 0.2-3.4 micro M as determined by a clonogenic assay and induces apoptosis. [1]
In Vivo Treatment of nude mice bearing human ovarian and colon tumor xenografts with PXD101 (10-40 mg/kg/day i.p.) daily for 7 days causes a significant dose-dependent growth delay with no obvious signs of toxicity to the mice. A marked increase in acetylation of H4 is detected in blood and tumor of mice 3 h after treatment with PXD101.[1]
激酶实验 For activity assays, the reaction was carried out in a total volume of 150 μl of buffer [60 mm?Tris (pH 7.4) containing 30% glycerol] containing 2 μl of cell extract and, where used, 2 μl of PXD101. The reaction was started by the addition of 2 μl of [3H]labeled substrate (acetylated histone H4 peptide corresponding to the 20 NH2-terminal residues). Samples were incubated at 37°C for 45 min, and the reaction stopped by the addition of HCl and acetic acid (0.72 and 0.12?m?final concentrations, respectively). Released [3H]acetate was extracted into 750 μl of ethyl acetate, and samples were centrifuged at 12,000 ×?g?for 5 min. The upper phase (600 μl) was transferred to 3 ml of scintillation fluid and counted.[1]

细胞实验 For the human tumor xenograft studies, monolayer cultures were harvested with trypsin/EDTA (0.25%/1 mm?in PBS) and resuspended in PBS. About 107?cells were injected s.c. into the right flank of athymic nude mice (CD1?nu/nu?mice from Charles River). After 10–15 days when the mean tumor diameter was ≥0.5 cm, animals were randomized into groups of six for experiments. PXD101 was dissolved in DMSO and then diluted in water to give a final concentration of DMSO of 10% and was administered i.p. at the times specified. This formulation gave sufficient solubility for doses of ≤40 mg/kg. Mice were weighed daily, and tumor volumes were estimated by caliper measurements assuming spherical geometry (volume =?d3?× π/6). Mice were also observed daily for any changes in behavior or condition according to the Morton and Griffiths scoring system (14). Significant differences between groups were identified by ANOVA, and the significance level of individual differences was determined by Student’s?t?test.[1]
