Epigenomics Profiling Core
Services
- Epigenomics Profiling Core
- DNA Methylation Analysis Services
- High-throughput ChIP Services
The Epigenomics Profiling Core (EpiCore) is funded by the Center for Cancer Epigenetics and the Department of Epigenetics and Molecular Carcinogenesis. The overall goal of this core is to facilitate researchers’ efforts to define the epigenetic mechanisms that alter the state of chromatin to regulate transcription in normal versus disease conditions.
Our Purpose
The purpose of the Epigenomics Profiling Core is to actively participate in and contribute to the growing epigenetics community at MD Anderson and across the Texas Medical Center by providing services to analyze epigenetic alterations with a dual focus on DNA methylation analysis and high-throughput chromatin immunoprecipitation (ChIP) services.
EpiCore Overview
DNA Methylation Analysis Services
Methylation events occurring at specific sites in DNA were one of the earliest identified epigenetic modifications to chromatin. DNA methylation is essential for normal development and is associated with a number of key processes, such as imprinting. DNA methylation, which can be reversed, commonly affects gene transcription. This is particularly true when methylation occurs within genomic regulatory elements. Thus, alterations in DNA methylation patterns reflect important epigenetic changes. The DNA Methylation Analysis Service provides investigators access to both global and gene-specific DNA methylation analysis through a wide array of methods.
Our services include:
• Consultation with investigators to choose the best method of analysis
• Sample preparation
• Assay design
• Sample processing for commonly used gene-specific and genome-wide methods to study DNA methylation:
- PyroMeth
- RRBS
- Methyl-Seq
• Assessment of global DNA methylation by pyrosequencing for analysis of repetitive elements (e.g. LINE-1 and Alu repeats)

High-Throughput ChIP-Seq Services
One of the major questions for researchers interested in understanding chromatin dynamics is how protein-DNA interactions alter the epigenetic landscape to alter gene expression. Chromatin immunoprecipitation (ChIP) is used to interrogate protein-DNA interactions at specific genomic sites. ChIP-Seq (ChIP followed by deep sequencing of DNA) enables identification of regions enriched for chromatin-bound proteins across the genome. The High-Throughput ChIP-Seq Service provides an innovative, cost-effective, 96-well platform to deliver high-quality, sequencing-ready libraries to map histone modifications, transcriptional co-regulators and transcription factors genome-wide.
Our services include:
• Consultation with investigators to choose the best method of analysis
• Extraction of high-quality chromatin from cell and tissue samples
• ChIP using a set of validated antibodies for specific histone marks (below), or investigator preferred antibodies
-H3K4me3, H3K27me3 (promoters)
-H3K4me1, H3K27ac (enhancers)
-H3K36me3, H3K79me2 (gene bodies)
-H3K9me3 (heterochromatin)
• Sequencing library preparation from the immunoprecipitated material
