Histone acetylation dynamics modulates chromatin conformation and allele-specific interactions at oncogenic loci

Elisa Oricchio, Daniele Tavernari, Natalya Katanayeva, Stephanie Jocelyne Sungalee, Ruxandra-Andreea Lambuta

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 ...

Whole-genome doubling drives oncogenic loss of chromatin segregation

Juan Diaz Miyar, Elisa Oricchio, Natalya Katanayeva, Daniele Tavernari, Ruxandra-Andreea Lambuta

Whole-genome doubling (WGD) is a recurrent event in human cancers and it promotes chromosomal instability and acquisition of aneuploidies(1-8). However, the three-dimensional organization of chromatin in WGD cells and its contribution to oncogenic phenotyp ...

Cathepsin S Regulates Antigen Processing and T Cell Activity in Non-Hodgkin Lymphoma

Bruno Emanuel Ferreira De Sousa Correia, George Coukos, Elisa Oricchio, Julien Racle, Sarah Wehrle, Elena Battistello, Jessica Sordet, Natalya Katanayeva, Stephanie Jocelyne Sungalee, Elie Charles Eugène Dheilly

Genomic alterations in cancer cells can influence the immune system to favor tumor growth. In non-Hodgkin lymphoma, physiological interactions between B cells and the germinal center microenvironment are coopted to sustain cancer cell proliferation. We fou ...

Individual transcription factors modulate both the micromovement of chromatin and its long-range structure

David Michael Suter, Natalya Katanayeva, Haitham Ahmed Shaban Ahmed, Armelle Inge Marie Eleonore Tollenaere

The control of eukaryotic gene expression is intimately connected to highly dynamic chromatin structures. Gene regulation relies on activator and repressor transcription factors (TFs) that induce local chromatin opening and closing. However, it is unclear ...

Genetic and epigenetic inactivation of SESTRIN1 controls mTORC1 and response to EZH2 inhibition in follicular lymphoma

Elisa Oricchio, Elena Battistello, Stephanie Jocelyne Sungalee, Natalya Katanayeva, Maria Christine Donaldson

Follicular lymphoma (FL) is an incurable form of B cell lymphoma. Genomic studies have cataloged common genetic lesions in FL such as translocation t(14;18), frequent losses of chromosome 6q, and mutations in epigenetic regulators such as EZH2 Using a focu ...

Antibody-peptide conjugates deliver covalent inhibitors blocking oncogenic cathepsins

Bruno Emanuel Ferreira De Sousa Correia, Luc Reymond, Florence Pojer, Elisa Oricchio, Sandrine Madeleine Suzanne Georgeon, Kelvin Ka Ching Lau, Sarah Wehrle, Aaron Simone Petruzzella, Natalya Katanayeva, Albert Santamaria Martinez, Marine Jeanne Françoise Bruand

Cysteine cathepsins are a family of proteases that are relevant therapeutic targets for the treatment of different cancers and other diseases. However, no clinically approved drugs for these proteins exist, as their systemic inhibition can induce deleterio ...

EZH2 oncogenic mutations drive epigenetic, transcriptional, and structural changes within chromatin domains

Suliana Manley, Elisa Oricchio, Kyle Michael Douglass, Daniele Tavernari, Elena Battistello, Natalya Katanayeva, Stephanie Jocelyne Sungalee, Maria Christine Donaldson, Timo Henry René Rey

Chromatin is organized into topologically associating domains (TADs) enriched in distinct histone marks. In cancer, gain-of-function mutations in the gene encoding the enhancer of zeste homolog 2 protein (EZH2) lead to a genome-wide increase in histone-3 L ...
