Cell-autonomous inflammation of BRCA1-deficient ovarian cancers drives both tumor-intrinsic immunoreactivity and immune resistance via STING

Julien Dorier, George Coukos, Christian Iseli, Mauro Delorenzi, Alizée Jéléna Grimm, Giovanni Ciriello, Alexandre Harari, Marco Mina

In this study, we investigate mechanisms leading to inflammation and immunoreactivity in ovarian tumors with homologous recombination deficiency (HRD). BRCA1 loss is found to lead to transcriptional reprogramming in tumor cells and cell-intrinsic inflammat ...

Systematic inference and comparison of multi-scale chromatin sub-compartments connects spatial organization to cell phenotypes

Elisa Oricchio, Stephanie Jocelyne Sungalee, Daniele Tavernari, Giovanni Ciriello, Marco Mina

Chromatin compartmentalization reflects biological activity. However, inference of chromatin sub-compartments and compartment domains from chromosome conformation capture (Hi-C) experiments is limited by data resolution. As a result, these have been charac ...

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

Bruno Emanuel Ferreira De Sousa Correia, George Coukos, Elisa Oricchio, Natalya Katanayeva, Julien Racle, Jessica Sordet, Sarah Wehrle, Elena Battistello, 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 ...

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

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

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 ...

Pan-Cancer Landscape of Aberrant DNA Methylation across Human Tumors

Douglas Hanahan, Mohammad Sadegh Saghafinia, Giovanni Ciriello, Marco Mina

The discovery of cancer-associated alterations has primarily focused on genetic variants. Nonetheless, altered epigenomes contribute to deregulate transcription and promote oncogenic pathways. Here, we designed an algorithmic approach (RESET) to identify a ...

Conditional Selection of Genomic Alterations Dictates Cancer Evolution and Oncogenic Dependencies

Elisa Oricchio, Mohammad Sadegh Saghafinia, Elena Battistello, Daniele Tavernari, Stephanie Jocelyne Sungalee, Franck Claude Raynaud, Giovanni Ciriello, Marco Mina, Titouan Laessle

Cancer evolves through the emergence and selection of molecular alterations. Cancer genome profiling has revealed that specific events are more or less likely to be co-selected, suggesting that the selection of one event depends on the others. However, the ...
