The mechanism includes DNA methylation, histone modification, chromatin remodeling, non- coding RNA, chromatin higher order structure and nuclear spatial localization, etc. Epigenetics plays an important role in many physiological and pathological processes such as cell fate determination, stem cell self-replication, cell differentiation, reproductive regulation, ontogenesis, tumorigenesis and development, immune cell activation, etc. It is also an important bridge mechanism that links the external environment influences with internal gene and cellular functions. Moreover, most epigenetic regulatory processes are reversible, which are precisely positive or negative regulated by the enzyme reactions. Therefore, research on epigenetic regulation not only helps us to understand life processes, many epigenetic regulatory factors are also ideal drug targets for tumors, infertility, cardiovascular diseases, nervous system diseases.</p> <p> Many specific and continuously optimized technical methods in the field of epigenetics promote the development of epigenetics. Such as analyzing the nucleosome localization based on enzymes cleavage (MNase, DNAse, various endonuclease enzymes, etc.), tracing the histone modification locations in the genome wide through Chromatin Immunoprecipitation (ChIP), mapping the open chromatin region by the Transposase- Accessible Chromatin with high-throughput sequencing (ATAC-Seq), and mapping chromatin interaction through the Chromosomal Conformational Capture.</p> <p><img src="https://www.polscientific.com/jbm/public/site/images/cheryl_zhu/jbm-small-size-c079faa72e492975bf22ba6be0de9b9e.jpg" alt="" width="419" height="593" /></p> <p> </p> <p><strong>Guest</strong> <strong>Editors-in-Chief</strong> <strong>Profile</strong></p> <p><strong>Guohong Li </strong>Professor at the School of Life Sciences, Wuhan University.</p> <p> Researcher, Institute of Biophysics, Chinese Academy of Sciences.</p> <p> His main research interests are the epigenetic regulation of chromatin higher order structures during transcription and its biological functions in determining cell fate during programming and reprogramming of embryonic stem cells.</p> <p> He received his undergraduate degree from Wuhan University in 1995, his master's degree from the Department of Biophysics, Faculty of Medicine, Peking University in 1998, and his PhD degree from the University of Heidelberg/Maple Cell Institute, Germany in 2003.

Here, we integrate Hi-C, WGS and RNA-seq to study the 3D genome architecture of multiple myeloma (MM) and how it associates with genomic variation and gene expression. Our results show that Hi-C interaction matrices are biased by copy number variations (CNVs) and can be used to detect CNVs. Also, combining Hi-C and WGS data can improve the detection of translocations. We find that CNV breakpoints significantly overlap with topologically associating domain (TAD) boundaries. Compared to normal B cells, the number of TADs increases by 25% in MM and the average size of TADs is smaller, and about 20% of genomic regions switch their chromatin A/B compartment types. In summary, we report a 3D genome interaction map of aneuploid multiple myeloma cells and reveal the relationship among CNVs, translocations, 3D genome reorganization, and gene expression regulation.</p> <p> </p> <p><strong>Accepted</strong> <strong>types</strong> <strong>of</strong> <strong>manuscripts:</strong></p> <p><strong>1.
