3D chromatin structure in colon cancer

Project description:We report the application of in situ Hi-C technology to 40 colorectal cancer patients and 10 paired-normal tissue to identify CRC specific changes in 3D chromatin structure. The chromatin contact matrices were generated by the sequencing data and image processing/deep learning-based algorithm was proposed to identify long-range abnormal chromatin interaction patterns in the contact matrices. The tumor specific 3D chromatin structure changes and the enhancer-promoter rewiring mediated by the identified chromatin structure changes were analyzed. The complex chromosome-wide rearrangements such as chromothripsis and its effect to 3D chromatin structure were also observed.

KLF4 inhibits early neural differentiation of ESCs by coordinating specific 3D chromatin structure

Project description:Neural differentiation of embryonic stem cells (ESCs) requires precisely orchestrated gene regulation, a process governed in part by changes in 3D chromatin structure. How these changes regulate gene expression in this context remains unclear. In this study, we observed enrichment of the transcription factor KLF4 at some poised or closed enhancers at TSS-linked regions of genes associated with neural differentiation, such as Pax6. Combination analysis employing ChIP, HiChIP and RNA-seq data indicated that KLF4 loss in ESCs induced changes in 3D chromatin structure, including increased chromatin interaction loops between neural differentiation-associated genes and active enhancers. And changes of chromatin structure upregulated expression of neural differentiation-associated genes and promoted early neural differentiation. This study reveals that KLF4 has a differentiation inhibitory effect in regulating 3D chromatin structure and suggests KLF4 inhibits early neural differentiation by regulation of 3D chromatin structure, which is a new mechanism of early neural differentiation.

Predicting modulaters of TE-driven chromatin 3D structure (HiC)

Project description:DNA is tightly packaged in the human nucleus and is wrapped in complex three-dimensional (3D) structures that have been implicated in regulatory processes However, no comprehensive model describes the formation of the 3D genome. At least 40% of the human genome consists of fossilized inactive transposable element (TE) sequences. A role for TEs in 3D genome structure has been suggested by several studies that illustrate how TEs are involved in 3D genome formation. However mechanisms that mediate the formation of TE-mediated 3D contacts is lacking. As TEs are rich in TF binding sites it seems likely that TFs bound to TEs are responsible for forming the 3D genome structure. We used the comprehensive TF binding data available in human and mouse pluripotent stem cells (PSCs), coupled with HiC data to explore the role of TFs bound to TEs in 3D genome organization. Based on these computational predictions we divide TFs into three main classes, those that utilize TEs to drive 3D genome formation, those that are neutral, and a third class that breaks 3D contacts at specific TEs. We then experimentally validate four proteins, and show that SMARCA5 and MAFK are involved in promoting chromatin contacts at TEs, whilst E2F6 and KDM1A are disruptive.
