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 ( ...
Springernature2024Whole genome doubling promotes tumorigenesis through loss of chromatin segregation and compartment repositioning
Whole genome doubling (WGD) events are drivers of genetic innovation across vertebrate evolution. While generally detrimental to mammalian organisms, WGDs are crucial in the development of various plants and fungi, as well as for the terminal differentiati ...
EPFL2023The THO complex counteracts TERRA R-loop-mediated telomere fragility in telomerase(+) cells and telomeric recombination in ALT(+) cells
Joachim Lingner, Rita Valador Fernandes
Telomeres are the nucleoprotein structures at the ends of linear chromosomes. Telomeres are transcribed into long non-coding Telomeric Repeat-Containing RNA (TERRA), whose functions rely on its ability to associate with telomeric chromatin. The conserved T ...
OXFORD UNIV PRESS2023Histone 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 ...
2021Roles of Epigenetic Dysregulation in Cancer Progression and Metastasis
Nearly all the cells of an organism share the same DNA sequence or genome, and yet they show different phenotypes and carry out different functions. This diversity is made possible by a verity of molecular modifications acting on the DNA sequence that coll ...
EPFL2020Computational study of transcription factor binding sites
Any living organism contains a whole set of instructions encoded as genes on the DNA. This set of instructions contains all the necessary information that the organism will ever need, from its development to a mature individual to environment specific resp ...
EPFL2020Expression and differential regulation of human TERRA at several chromosome ends
Joachim Lingner, Marianna Feretzaki, Patricia Renck Nunes
The telomeric long noncoding RNA TERRA has been implicated in regulating telomere maintenance by telomerase and homologous recombination, and in influencing telomeric protein composition during the cell cycle and the telomeric DNA damage response. TERRA tr ...
COLD SPRING HARBOR LAB PRESS, PUBLICATIONS DEPT2019Histone Modifications in Development and Malignancy
Non-Hodgkin lymphoma (NHL) development is driven by the accumulations of multiple genetic, epigenetic, and chromosomal alterations. These lesions can lead to modifications of the chromatin architecture. To identify novel oncogenic interactions driven by mo ...
AMER SOC HEMATOLOGY2019A Tale of Two Tumors: Unraveling the Complexities of Epigenetic Dysregulation in Cancer
Epigenetics plays an important role in cancer development and progression. Cancer cells hijack the epigenome by modifying the histone protein units responsible for packaging DNA, or by modifying the DNA itself, resulting in changes to chromatin topology an ...
EPFL2019Mitotic chromosome binding predicts transcription factor properties in interphase
Mammalian transcription factors (TFs) differ broadly in their nuclear mobility and sequence-specific/non-specific DNA binding affinity. How these properties affect the ability of TFs to occupy their specific binding sites in the genome and modify the epige ...
