UMI-4C for quantitative and targeted chromosomal contact profiling

ABSTRACT: We developed a targeted chromosome conformation capture (4C) approach that uses unique molecular identifiers (UMI) to derive high complexity quantitative chromosome contact profiles with controlled signal to noise ratios. We demonstrate that the method improves the sensitivity and specificity for detection of long-range chromosomal interactions, and that it allows the design of interaction screens with predictable statistical power. UMI-4C robustly quantifies contact intensity changes between cell types and conditions, opening the way toward incorporation of long-range interactions in quantitative models of gene regulation. We constructed UMI-4C profiles of 13 different genomic loci (viewpoints) in five different cell lines, in order to study the 3D chromatin contact maps of these selected loci. The coordinates for these viewpoints are: G1p1 chrX:48646542; baitG1_3_5kb chrX:48641393; bait_50kb chrX:48595987; bait_165kb chrX:48476525; ANK1 chr8:41654693; hbb_3HS chr11:5221346; hbb_HBB chr11:5248714; hbb_HBBP1_G1 chr11:5266532; HBB_HBE chr11:5292159; HBB_HS2 chr11:5301345; HBB_HS3 chr11:5306690; HBB_HS5 chr11:5313539; HBB_HBD chr11:5256597

UMI-4C in control and Haster-deficient mouse livers

Project description:The HASTER promoter region is a cis-regulatory element that stabilizes the transcription of HNF1A, preventing silencing or overexpression. We have generated a mouse model where the promoter of Haster has been specifically deleted in liver (Haster loxP/loxP; AlbCre). In liver the prevailing consequence is upregulation of HNF1A. We performed UMI-4C experiments to assess how Haster inactivation remodel 3D chromatin interactions of the Hnf1a promoter using the Hnf1a promoter as viewpoint (V1, Hnf1a promoter upstream CTCF site viewpoint; V2, Hnf1a promoter VP).

UMI-4C in control and HASTER-deficient EndoC-betaH3 cells overexpressing HNF1A

Project description:The HASTER promoter region is a cis-regulatory element that stabilizes the transcription HNF1A. If HASTER is deleted after beta cells have been formed and HNF1A is already stably expressed, HASTER is not required to maintain HNF1A activity, and is only required to provide negative feedback on HNF1A. HNF1A binding to the HASTER promoter mediates the repression of the HNF1A gene itself. To determine whether HNF1A binding to the HASTER promoter remodels 3D chromatin interactions of the HNF1A promoter, we performed UMI-4C experiments in wild type and HASTER-promoter KO EndoC-betaH3 cells with or without doxycycline-induced HNF1A overexpression using the HNF1A promoter as viewpoint.

Circularized chromosome conformation capture (4C-seq) in A549 cells after glucocorticoid re-induction

Project description:We performed 4C-seq in the A549 cell line to investigate changes in chromatin interactions at the ZBTB16 locus. Cells were treated with either 100 nM dexamethasone or 0.1% ethanol. After 4 hours, cells were washed 2x with PBS and cultured in hormone-free medium for 24 hours, after which cells were treated again for 4 hours with either 100 nM dexamethasone or 0.1% ethanol. Experiments were performed in two biological replicates. For each treatment, 4C-seq data were generated for the following two viewpoints: ZBTB16 promoter-proximal viewpoint coordinates: chr11:113929670-113930464 (hg19) ZBTB16 intronic viewpoint coordinates: chr11:114051224-114051804 (hg19)

Transcription profiling of human mesechymal stem cells exposed to keratinocyte conditioned medium

Project description:In the present study, we demonstrate that hMSCs migrate toward human keratinocytes as well as toward conditioned medium from cultured human keratinocytes (KCM) indicating that the hMSCs can respond to signals from keratinocytes. Incubation of hMSCs with KCM induced dermal myofibroblast like differentiation characterized by expression of cytoskeletal markers vinculin and F-actin filaments with increased expression of alpha smooth muscle actin. We then examined the therapeutic efficacy of hMSCs in wound healing in two animal models representing normal and chronic wound healing. Accelerated wound healing, as determined by quantitative measurements of wound area, was observed when hMSCs and KCM exposed hMSCs (KCMSCs) were injected near the site of incisional/excisional wounds in nondiabetic athymic and NOD/SCID mice as compared with normal human fetal lung fibroblast WI38 cells or saline control induced wound healing. Experiment Overall Design: Keratinocyte conditioned media exposed MSCs(KCMSCs) were used in the experiment in triplicates as follows; Experiment Overall Design: KCM_1 Experiment Overall Design: KCM_2 Experiment Overall Design: KCM_3 Experiment Overall Design: Where as MSCs were exposed to Keratinocyte growth media for 30 days were used as a controls as follow; Experiment Overall Design: KGM_1 Experiment Overall Design: KGM_2 Experiment Overall Design: KGM_3 Experiment Overall Design: All the samples were analyzed.

Mapping the inter- and intra-chromosomal interactions of specific insulator binding sites with circular chromosome conformation capture (4C) assay (Gondor et al., 2008 Nature Protocol) [NimbleGen Array data]

Project description:Drosophila Insulator proteins mediate long-range chromosomal interactions. ChIP-seq revealed that binding of insulator proteins to some specific DNA sites was regulated by poly(ADP-ribosyl)ation in S2 cells. Three insulator sites regulated by poly(ADP-ribosyl)ation were used as baits to map their distant interacting sites using 4C assay in control S2 cells. Mapping the chromosomal interactions of three specific insulator binding sites with 4C assay in control S2 cells.

RNA-seq analysis of neonatal mouse cochlear supporting cells [NonTreated_JM]

Project description:This study examined transcripts that are enriched in neonatal mouse cochlear supporting cells at postnatal day 1 and postnatal day 6. Supporting cells were purified by FACS sorting for GFP fluorescence from the cochleas of transgenic mice in which a BAC including the LFng locus drives the expression of GFP. Two replicates of GFP+ supporting cells were compared with all other cochlear cell types that were GFP-. We performed this experiment at two different ages, postnatal day 1 and postnatal day 6. mRNA profiles of supporting cells (GFP+) and all other cochlear cell types (GFP-), two replicates each, at P1 and P6 mice were generated by deep sequencing using Illumna TruSeq.
