Microscopy-Based Chromosome Conformation Capture Enables Simultaneous Visualization of Genome Organization and Transcription in Intact Organisms
Andrés M. Cardozo Gizzi,Diego I. Cattoni,Jean-Bernard Fiche,Sergio Martín Espínola,Julian Gurgo,Olivier Messina,Christophe Houbron,Yuki Ogiyama,Giorgio L. Papadopoulos,Giacomo Cavalli,Mounia Lagha,Marcelo Nollmann +11 more
TL;DR: The ability of Hi-M to explore the multi-scale chromosome architecture with spatial resolution at different stages of development or during the cell cycle will be key to understanding the mechanisms and consequences of the 4D organization of the genome.

TL;DR: This work investigates the 3D architecture of Drosophila melanogaster PCH domains and their spatial associations with the euchromatic genome by developing a novel analysis method that incorporates genome-wide Hi-C reads originating from PCH DNA and reveals a hierarchical organization of the P CH domains into distinct “territories.”

TL;DR: Hi-M was used to study chromosome organization during the awakening of the zygotic genome in intact Drosophila embryos and was able to unveil the changes in 3D chromatin organization occurring upon transcriptional activation and homologous chromosome un-pairing.

Pericentromeric heterochromatin is hierarchically organized and spatially contacts H3K9me2/3 islands located in euchromatic genome
Yuh Chwen G. Lee,Yuki Ogiyama,Nuno Martins,Brian J. Beliveau,David Acevedo,C.-ting Wu,Giacomo Cavalli,Gary H. Karpen +7 more
TL;DR: The authors investigated the 3D structure of Drosophila melanogaster pericentromeric heterochromatin (PCH) domains and their spatial associations with euchromatic genome by developing a novel analysis method that incorporates genome-wide Hi-C reads originating from PCH DNA.

TL;DR: In this paper, a multiplexed, sequential imaging approach (Hi-M) is presented for simultaneous detection of chromosome organization and transcription in single nuclei, which can reveal the changes in 3D chromatin organization occurring upon transcriptional activation and homologous chromosome unpairing.
