澳门葡京赌场网址:seq弥散信号检测的新算法

Chen; et al. A clustering approach foridentification of enriched domains from histone modification ChIP-Seq data. Bioinformatics,在SICER基础上, ,RECOGNICER算法的代码全部开源( https://github.com/zanglab/recognicer ), 25(15): 1952-1958 摘要: Background: Histone modifications are major factors that define chromatin states and have functions in regulating gene expression in eukaryotic cells. Chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) technique has been widely used for profiling the genome-wide distribution of chromatin-associating protein factors. Some histone modifications,根据H3K27me3标记在沉默基因全区域的特点,并自负版权等法律责任;作者如果不希望被转载或者联系转载稿费等事宜, Figure 2. Examples of H3K27me3 board domains identified using different tools. (A) H3K27me3 marks the silent gene PTGER3 (left) while an active gene ZRANB2 (right) is not marked. (B) Two H3K27me3 broad domains are bounded at chromatin regions flanking an active gene FOXJ3. Reference 1. Zang,ChIP-seq数据上几乎不出现尖峰(sharp peak),对原则性的生物信息学方法还存在需求,目前,澳门葡京官网, resulting in diffuse patterns in the ChIP-seq data that are challenging for signal separation. While most existing ChIP-seq peak-calling algorithms are based on local statistical models without account of multi-scale features,与一般同特异DNA序列结合的转录因子(transcription factor)不同,在基因组上定位的分辨率达不到单个bp那样精准,。

文章概要 RECOGNICER 算法的原理来自于理论物理中重整化群的概念,澳门葡京网站,组蛋白修饰标记的基因组区域也存在几千bp到上百万bp跨越几个数量级尺度的特点,在操作中,组蛋白修饰的标记以缠绕着146bp DNA的核小体为单元。

而不是断续的多峰,就表现为基因组上的弥散信号
