Analysing and interpreting dna methylation data. Analysing and interpreting DNA methylation data Christoph Bock Abstract DNA methylation is an epigenetic mark that has suspected regulatory roles in a broad range of biological processes and diseases. The technology is now available for studying DNA methylation genome-wide at a high resolution and in a large number of samples. The analysis and interpretation of genome-wide DNA methylation data poses unique bioinformatics challenges.
In this article the tools that are available for processing visualizing and. To interpret DNA methylation data must be processed visualized and statistically analyzed 2 3 57. The outcome of this workflow should be methylation levels for different positions and.
The technology is now available for studying DNA methylation genome-wide at a high resolution and in a large number of samples. This Review discusses relevant concepts computational methods and software tools for analysing and interpreting DNA methylation data. Figure 3 Effective identification of differentially methylated regions in a highly annotated genome.
A An illustrative example of differences in DNA methylation within the promoter region of a gene and at an upstream enhancer. For easier visualization DNA methylation data are shown for only three cases and three controls a realistic number would be hundreds of samples and for ten CpGs. The technology is now available for studying DNA methylation genome-wide at a high resolution and in a large number of samples.
This Review discusses relevant concepts computational methods and software tools for analysing and interpreting DNA methylation data. 102 Analyzing DNA methylation data. For the remainder of this chapter we will explain how to do DNA methylation analysis using R.
The analysis process is somewhat similar to the analysis patterns observed in other sequencing data analyses. The process can be chunked to four main parts with further sub-chunks. DNA Methylation Data Analysis 1.
- Academia Sinica LSL NGS Workshop - DNA Methylation Data Analysis Yi-Feng Chang PhD. Molecular Medicine Research Center Chang Gung University ianyfchangmailcguedutw 03-2118800 3166 or 3528 20151118 1 2. High-throughput sequencing of bisulfite-converted DNA is a technique used to measure DNA methylation levels.
Although a considerable number of computational pipelines have been developed to analyze such data none of them tackles all the peculiarities of the analysis together revealing limitations that can force the user to manually perform additional steps needed for a complete processing of the data. Patterns of DNA methylation are significantly altered in cancers. Interpreting the functional consequences of DNA methylation requires the integration of multiple forms of data.
The recent advancement in the next-generation sequencing can help to. The use of WGBS and RRBS data in tandem with 450K methylation may help to expand the sample sizes available for cell-type specific and independent analyses. The methyLiftover utility will enhance the field of epigenomic research by expanding the comparability of DNA methylation data in the absence of the common Illumina 450K methylation data.
RnBeads is an integrated software package for the analysis and interpretation of DNA methylation data. Due to its modular design and optional graphical user interface the software is well suited for both beginners and experts in the field of DNA methylation analysis. DNA methylation analysis in R 1.

Analyzing and Interpreting DNA Methylation Data Christoph Bock PhD. From the Ce-M-M Research Center for Molecular Medicine discusses epigenetic study design the various methods for studying DNA methylation the bioinformatic analysis and interpretation of methylation data and. IDA lecture cycle on Analyzing and interpreting DNA methylation data.
The epigenome is recognized as a key missing piece of the etiological puzzle for human diseases. Indeed LUMC researchers are increasingly incorporating epigenomics approaches in their studies. In this study we develop a web service MADA for the whole process of methylation arrays data analysis which includes the steps of a comprehensive differential methylation analysis pipeline.
