Detecting long-range chromatin interactions using the chromosome conformation capture sequencing (4C-seq) method

, 2011
Eukaryotic transcription is tightly regulated by transcriptional regulatory elements, even though these elements may be located far away from their target genes. It is now widely recognized that these regulatory elements can be brought in close proximity

Studying physical chromatin interactions in plants using Chromosome Conformation Capture (3C) [PDF]

, 2009
Gene regulation in higher eukaryotes frequently involves physical interactions between genomic sequence elements tens of kilobases apart on the same chromosome but can also entail interactions between different chromosomes.

A Rare De Novo Missense Mutation in IFT122 Confers a Genetic Susceptibility Factor of Idiopathic Pediatric Uveitis Via Trio‐based Whole‐Exome Sequencing

Advanced Science, EarlyView.
A rare de novo IFT122‐A773E variant is identified in idiopathic pediatric uveitis and shown to exacerbate retinal inflammation and barrier dysfunction. Mechanistically, the variant enhances IFT43 interaction, elevates calcium signaling, and activates the MEK/ERK/FRA1 axis, revealing a previously unrecognized cilia‐associated pathway that may increase ...

The Landscape of Long Non‐Coding RNAs Provides Insights Into the Domestication and Improvement of Pear Fruit

Advanced Science, EarlyView.
This study reveals that long non‐coding RNAs represent important regulatory components underlying pear domestication and improvement. Integrative multi‐omics analyses identify selected lncRNAs associated with fruit traits, while functional validation uncovers a lignin‐related lncRNA, lncRNA‐pys, that promotes lignin accumulation.

Genome‐Wide and Multi‐Omics Analysis Identified DNA‐Interacting Circular RNA circFOXK2 as MLL1 Regulator for Histone H3K4 Methylation in Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
Circular RNA circFOXK2 is frequently upregulated in pancreatic ductal adenocarcinoma to promote tumor heterogeneity, growth, and metastasis. Through circRNA‐DNA interaction at different genomic locations, circFOXK2 removes the PPIE inhibitory effects on MLL1 for gene‐activating H3K4 methylation of the oncogenes.

Visualization and data exploration of chromosome conformation capture data using Voronoi diagrams with v3c-viz

Chromosome conformation capture (3C) sequencing approaches, like Hi-C or micro-C, allow for an unbiased view of chromatin interactions. Most analysis methods rely on so-called interaction matrices, which are derived from counting read pairs in bins of ...

Convergence of Plasmid‐Mediated tmexCD‐toprJ With Critical Resistance Genes Fuels Spread of Multidrug Resistant Bacteria

Advanced Science, EarlyView.
Global dissemination of tmexCD‐toprJ across bacterial hosts and ecological niches is accompanied by its convergence with blaKPC, blaNDM, and mcr on mobile plasmids. Recombination and acquisition of resistance modules generate distinct multidrug resistant plasmid architectures, facilitating the emergence and spread of high‐risk bacterial populations ...

A rapid simple approach to quantify chromosome conformation capture

Nucleic Acids Research, 2009
Chromosome conformation capture (3C) is a powerful tool to study DNA looping. The procedure generates chimeric DNA templates after ligation of restriction enzyme fragments juxtaposed in vivo by looping. These unique ligation products (ULPs) are typically quantified by gel-based methods, which are practically inefficient.
