چکیده

UNLABELLED ChIA-PET is rapidly emerging as an important experimental approach to detect chromatin long-range interactions at high resolution. Here, we present Model based Interaction Calling from ChIA-PET data (MICC), an easy-to-use R package to detect chromatin interactions from ChIA-PET sequencing data. By applying a Bayesian mixture model to systematically remove random ligation and random collision noise, MICC could identify chromatin interactions with a significantly higher sensitivity than existing methods at the same false discovery rate. AVAILABILITY AND IMPLEMENTATION http://bioinfo.au.tsinghua.edu.cn/member/xwwang/MICCusage CONTACT [email protected] or [email protected]. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

A Bayesian mixture model for chromatin interaction data.

Chromatin interactions mediated by a particular protein are of interest for studying gene regulation, especially the regulation of genes that are associated with, or known to be causative of, a disease. A recent molecular technique, Chromatin interaction analysis by paired-end tag sequencing (ChIA-PET), that uses chromatin immunoprecipitation (ChIP) and high throughput paired-end sequencing, is...

Statistical Models for Detecting Differential Chromatin Interactions Mediated by a Protein

Chromatin interactions mediated by a protein of interest are of great scientific interest. Recent studies show that protein-mediated chromatin interactions can have different intensities in different types of cells or in different developmental stages of a cell. Such differences can be associated with a disease or with the development of a cell. Thus, it is of great importance to detect protein...

Identifying chromatin interactions at high spatial resolution

This thesis presents two computational approaches for identifying chromatin interactions at high spatial resolution from ChIA-PET data. We introduce SPROUT which is a hierarchical probabilistic model that discovers high confidence interactions between binding events that it accurately locates. We apply SPROUT to CTCF ChIA-PET data from mouse embryonic stem cells and demonstrate that SPROUT disc...

Genome analysis Mango: a bias-correcting ChIA-PET analysis pipeline

Motivation: Chromatin Interaction Analysis by Paired-End Tag sequencing (ChIA-PET) is an established method for detecting genome-wide looping interactions at high resolution. Current ChIA-PET analysis software packages either fail to correct for non-specific interactions due to genomic proximity or only address a fraction of the steps required for data processing. We present Mango, a complete C...
