Circularized chromosome conformation capture (4C-seq) in A549 and U2OS cells stably expressing rat GR

Project description:To investigate the interaction landscape at the GILZ locus we performed 4C-seq in A549 (ATCC CCL-185) and U2OS cells stably expressing rat GR (Rogatsky et al. , Mol Cell Biol, 1997. 17(6): p. 3181-93.) upon hormone treatment (1.5 h, 1 M dexamethasone). Experiments were performed in two biological replicates using hg19 chrX:106,960,488-106,960,865 as a viewpoint.

How C/EBPa creates an elite cell state for reprogramming to pluripotency [4C]

Project description:Mouse Bcell, upon ectopic expression of the transcription factor Cebpa for 18h, can be reprogrammed to iPS with extremely high efficiency. To understand the molecular control of this phenomena we performed multiple high throughtput functionnal genomic analysis. Circularized chromosome conformation capture assay (4C) taking as view point Klf4 promoter and a putative enhancer situated a -100kb upstream

Three-dimensional proximity mapping of the DRGFP DNA double-strand break site in U2OS cells

Project description:We mapped the DNA sequences located in physical proximity to an I-SceI endonuclease-dependent DNA double-strand break (DSB) site to be able to study the impact of DSBs on the break-associated chromatin micro-environment. The I-SceI DSB site is part of a DRGFP transgene that serves as a reporter for homology-directed DSB repair and was stably integrated into U2OS human osteosarcoma cells (Pierce et al., Genes Dev, 1999). DRGFP-U2OS cells were modified to carry a stable Doxycycline (Dox)-inducible I-SceI transgene (TRE-I-SceI) as well as the Tet-ON vector from Contech. Circular chromosome conformation capture (4C) was used to identify DSB-proximal DNA. 4C amplified DNA was subjected to Illumina Hi-Seq 200 100 bp paired end sequencing and reads were mapped to the human genome. The resulting genome-wide map of I-SceI/DRGFP-proximal DNA allows for the investigation of changes in DSB-surrounding chromatin features following I-SceI-mediated DSB induction. 4C library of I-SceI (DRGFP)-proximal DNA contacts in DRGFP-U2OS cells was generated using Illumina Hi-Seq 2000 sequencing, data sets are from two independent experiments.

SREBF1 coordinates with master transcription factors in regulating lipid metabolism and cancer-promoting pathways in squamous cell carcinoma [4C]

Project description:To determine whether a TP63/KLF5-regulated super-enhancer region can impact SREBF1 transcription, circularized chromosome conformation capture (4C) assays were performed. 4C assays identified complex, extensive interactions between the SREBF1 promoter and the super-enhancer region Moreover, these DNA-DNA contacts were strictly confined within the super-enhancer region, highlighting the specificity of chromatin interactions

MEF2C interaction profiles (4C-seq) in SH-SY5Y and HEK cell lines

Project description:To characterize enhancer elements regulating the MEF2C gene during neurodevelopment, we performed among others Circularized Chromosome Conformation Capture (4C) sequencing in a neuronal cell line, SH-SY5Y, and a non-neuronal control, HEK. We found that, in a neuronal cell line, the MEF2C promoter interacts with several putative enhancer elements in its upstream region, forming a complex interaction network. Moreover, these interactions are completely absent in HEK cells.

Chromatin interaction of Cebpa during adipocyte differentiation (4C-Seq)

Project description:Cebpa is a critical transcription factor gene for adipocyte differentiation and adipose tissue development. However, mechanisms controlling Cebpa expression during adipogenic differentiation remain largely unknown. Here, we generated the high-resolution chromatin interaction maps of Cebpa in 3T3-L1 preadipocytes (3T3-L1) and 3T3-L1 adipocytes (3T3-L1-AD) using circularized chromosome conformation capture coupled with next-generation sequencing (4C-seq), and characterized differences in their chromatin interactomes and chromatin status of the interaction sites during adipogenic differentiation. We performed a 4C-seq experiment on inguinal white adipose tissue (iWAT) to evaluate whether chromatin interaction between Cebpa-L1-AD-En2 and Cebpa promoters in 3T3-L1 adipocytes also exists in mouse adipose tissue.
