Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos
Constitutive heterochromatin is essential for transcriptional silencing and genome integrity. The establishment of constitutive heterochromatin in early embryos and its role in early fruitfly development are unknown. Lysine 9 trimethylation of histone H3 ( ...
Springernature2024A Cluster of Evolutionarily Recent KRAB Zinc Finger Proteins Protects Cancer Cells from Replicative Stress–Induced Inflammation
Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Florian Huber, Cyril David Son-Tuyên Pulver, Olga Marie Louise Rosspopoff, Romain Forey, Joana Carlevaro Fita
Heterochromatin loss and genetic instability enhance cancer progression by favoring clonal diversity, yet uncontrolled replicative stress leads to mitotic catastrophe and inflammatory responses that promote immune rejection. KRAB domain-containing zinc fin ...
2024Regulation and impact of TERRA R-loops at human telomeres
Telomeres are the nucleoprotein structures found at the ends of linear chromosomes. They ensure that the termini of chromosomes are not inappropriately recognized as sites of DNA damage, and are therefore crucial for genome stability. In spite of the heter ...
EPFL2023CENP-A and CENP-B collaborate to create an open centromeric chromatin state
Beat Fierz, Wei Cai, Harsh Nagpal
Centromeres are epigenetically defined via the presence of the histone H3 variant CENP-A. Contacting CENP-A nucleosomes, the constitutive centromere associated network (CCAN) and the kinetochore assemble, connecting the centromere to spindle microtubules d ...
Berlin2023Deciphering the molecular events leading to the global restoration of the chromatin landscape during mitotic exit
Two fundamental properties of embryonic stem cells (ESCs) are their ability to self-renew and differentiate into all somatic cell types. Maintenance of their identity faces major challenges when transitioning through mitosis, as most DNA-binding proteins a ...
EPFL2023Telomere protection against oxidative stress
Telomeres are nucleoprotein structures at the ends of linear chromosomes, being essential for the maintenance of genomic integrity. Telomeres have a unique structure which distinguishes chromosome termini from DNA damage sites. Shelterin complexes are the ...
EPFL2023Histone acetylation dynamics modulates chromatin conformation and allele-specific interactions at oncogenic loci
Elisa Oricchio, Daniele Tavernari, Natalya Katanayeva, Stephanie Jocelyne Sungalee, Ruxandra-Andreea Lambuta, Giovanni Ciriello
In cancer cells, enhancer hijacking mediated by chromosomal alterations and/or increased deposition of acetylated histone H3 lysine 27 (H3K27ac) can support oncogene expression. However, how the chromatin conformation of enhancer-promoter interactions is a ...
