Bioinformatics in Epigenetics


Introduction of Epigenetics

Epigenetics is a reversible way of regulating gene expression. Through chemical modification of DNA and histones, it is determined whether specific genes can be expressed. Epigenetics regulates the occurrence and development of a variety of life activities and diseases, and has become a research hotspot in the field of life sciences in recent years, prompting breakthroughs in research in multiple fields of biology. With the advancement of experiments and sequencing technologies, massive amounts of epigenome data are currently being produced. Mining biological characteristics from these data is of great significance to understanding the physiological and pathological processes of life. Faced with massive amounts of data including DNA methylation profiles, histone modification profiles, and chromosome open information, researchers have developed analysis tools and strategies for different data. Understanding and mastering the analysis methods of epigenome data will help researchers engaged in epigenome research to dig deeper into the regulation mechanisms of important processes such as disease, development and aging, and provide potential targets for further experimental and clinical application research. CD Genomics relies on years of data analysis experience to provide scientific research assistance to researchers.

Significance of Epigenetics Data Analysis

  • DNA methylation analysis: quantitatively study the methylation patterns of the genome using technologies based on sequencing and microarrays.
  • DNA-protein interaction analysis: In-depth understanding of the interaction between protein and DNA, to study the potential effects of chromatin modification and local structural changes on gene expression. 
  • Chromatin accessibility analysis: Use ATAC-Seq to evaluate open chromatin regions in the genome. ATAC-Seq can perform high-resolution sequencing on a large number of cell populations or single cells.

Application of Epigenetics Data in Biomedical Research

  • Complex disease research: By analyzing the epigenetics data of normal samples and diseased samples, mining-related mutation information, finding genetic mutations related to the occurrence and development of complex diseases, and discovering disease mechanisms.
  • Personalized diagnosis and treatment: By understanding the occurrence and development of related diseases from the genetic level, it will bring new technologies and new methods for the diagnosis and treatment of diseases, such as genetic diagnosis, gene therapy, and targeted drugs.
