Recently we characterized a class of anti-cancer agents (curaxins) that disturbs DNA/histone interactions within nucleosomes. Here, using a combination of genomic and in vitro approaches, we demonstrate that curaxins strongly affect spatial genome organization and compromise enhancer-promoter communication, which is necessary for the expression of several oncogenes, including MYC. We further show that curaxins selectively inhibit enhancer-regulated transcription of chromatinized templates in cell-free conditions. Genomic studies also suggest that curaxins induce partial depletion of CTCF from its binding sites, which contributes to the observed changes in genome topology. Thus, curaxins can be classified as epigenetic drugs that target the 3D genome organization.

Research into the three-dimensional (3D) organization of the cancer cell genome started over 100 years ago. We follow an exciting avenue of research in this field, from Hansemann's early observations ...
Through dissecting the link between spatial genome organization and DNA replication timing, Sima et al. (2018) discover early replicating control elements (ERCEs), a new type of cis-acting elements t...
In this essay, I propose that DNA-binding anti-cancer drugs work more via chromatin disruption than DNA damage. Success of long-awaited drugs targeting cancer-specific drivers is limited by the hetero...
A transcriptional regulatory network (TRN) is a complex network composed of all regulatory interactions between transcription factors and corresponding target genes. Recently, three-dimensional (3D) g...

The purpose of this study is to investigate genetic mutations affecting prognosis using whole genome sequencing in patients with biliary tract cancer.
Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.

Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
