动机:胞嘧啶的两种主要表观遗传修饰,5-甲基胞嘧啶(5-mC)和5-羟甲基胞嘧啶(5-hmC),在一系列哺乳动物细胞群体中彼此共存。越来越多的证据表明,5-hmC在5-mC的去甲基化和发育中的表观基因组调控中发挥重要作用。最近开发的实验方法允许直接单碱基分析5-hmC或5-mC。有意义的分析似乎需要将这些实验与亚硫酸氢盐测序相结合,但这样做会产生不一致的5-mC或5-hmC水平估计值。结果如下:我们提出了一种方法来联合模型读段计数从亚硫酸氢盐测序,氧化亚硫酸氢盐测序和Tet-Assisted亚硫酸氢盐测序,提供5-hmC和5-mC水平的同时估计是一致的跨实验类型。可用性:http://smithlab.usc.edu/software/mlml联系:andrewds@usc.edu补充信息:补充材料可在生物信息学在线。
Motivation: The two major epigenetic modifications of cytosines, 5-methylcytosine (5-mC) and 5-hydroxymethylcytosine (5-hmC), coexist with each other in a range of mammalian cell populations. Increasing evidence points to important roles of 5-hmC in demethylation of 5-mC and epigenomic regulation in development. Recently developed experimental methods allow direct single-base profiling of either 5-hmC or 5-mC. Meaningful analyses seem to require combining these experiments with bisulfite sequencing, but doing so naively produces inconsistent estimates of 5-mC or 5-hmC levels. Results: We present a method to jointly model read counts from bisulfite sequencing, oxidative bisulfite sequencing and Tet-Assisted Bisulfite sequencing, providing simultaneous estimates of 5-hmC and 5-mC levels that are consistent across experiment types.
