Circular Chromosome Conformation Capture (4C-Seq) Analysis of HBV-Host Chromosome DNA Interactome.
Article in Methods in molecular biology (Clifton, N.J.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hepatitis B virus (HBV) infects hepatocytes that are in the G0/G1 phase with intact nuclear membrane and organized chromosome architecture. In the nucleus of the infected cells, HBV covalently closed circular (ccc) DNA, an episomal minichromosome, serves as the template for all viral transcripts and the reservoir of persistent infection. Nuclear positioning of cccDNA can be assessed by the spatial distance between viral DNA and host chromosomal DNA through Circular Chromosome Conformation Capture (4C) combined with high-throughput sequencing (4C-seq). The 4C-seq analysis relies on proximity ligation and is commonly used for mapping genomic DNA regions that communicate within a host chromosome. The method has been tailored for studying nuclear localization of HBV episomal cccDNA in relation to the host chromosomes. In this study, we present a step-by-step protocol for 4C-seq analysis of HBV infection, including sample collection and fixation, 4C DNA library preparation, sequence library preparation, and data analysis. Although limited by proximity ligation of DNA fragments, 4C-seq analysis provides useful information of HBV localization in 3D genome, and aids the understanding of viral transcription in light of host chromatin conformation.
