A Cluster of Evolutionarily Recent KRAB Zinc Finger Proteins Protects Cancer Cells from Replicative Stress–Induced Inflammation
Didier Trono, Priscilla Turelli, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Florian Huber, Olga Marie Louise Rosspopoff, Romain Forey, Sandra Eloise Kjeldsen, Cyril David Son-Tuyên Pulver, 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 ...
2024Accessible and highly observable gastrointestinal organoid model systems for studying host-pathogen interactions
Traditional cell cultures have long been fundamental to biological research, offering an alternative to animal models burdened by ethical constraints and procedural intricacies, often lacking relevance to human physiology and disease. Moreover, their inabi ...
EPFL2024Deciphering the nature of cell state transitions in single cells using quantitative modeling of temporal dynamics
Cells are the smallest operational units of living systems. Through synthesis of various biomolecules and exchange of signals with the environment, cells tightly regulate their composition to realize a specific functional state. The transformation of a cel ...
EPFL2024Transposable elements mediate genetic effects altering the expression of nearby genes in colorectal cancer
Didier Trono, Evaristo Jose Planet Letschert, Nikolaos Lykoskoufis
Transposable elements (TEs) are prevalent repeats in the human genome, play a significant role in the regulome, and their disruption can contribute to tumorigenesis. However, TE influence on gene expression in cancer remains unclear. Here, we analyze 275 n ...
2024Inheritance 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 ( ...
Springernature2024The dynamic genetic determinants of increased transcriptional divergence in spermatids
Cis-genetic effects are key determinants of transcriptional divergence in discrete tissues and cell types. However, how cis- and trans-effects act across continuous trajectories of cellular differentiation in vivo is poorly understood. Here, we quantify al ...
Berlin2024Single-cell epigenomic reconstruction of developmental trajectories from pluripotency in human neural organoid systems
Cell fate progression of pluripotent progenitors is strictly regulated, resulting in high human cell diversity. Epigenetic modifications also orchestrate cell fate restriction. Unveiling the epigenetic mechanisms underlying human cell diversity has been di ...
Nature Portfolio2024Exploration and modulation of mechanical cues for enhanced cancer immunotherapy
The advent of immunotherapy, such as immune checkpoint blockade (ICB) and adoptive transfer of cytotoxic lymphocytes, has transformed the clinical care of cancer. However, a significant proportion of patients are resistant to immunotherapy or experience re ...
EPFL2024Exploring the role of cGAS-STING-mediated inflammation in age-associated neurodegeneration and antitumor immunity
Inflammation stands as a dynamic and intricate biological process, promoting vital defence mechanisms against harmful stimuli, including infections and injuries, to drive pathogen clearance and healing. On one hand, these responses can manifest acutely and ...
EPFL2024Meeting our Makers:Uncovering the cis-regulatory activity of transposable elements using statistical learning
The adaptation of organisms to their environment depends on the innovative potential inherent to genetic variation. In complex organisms such as mammals, processes like development and immunity require tight gene regulation. Complex forms emerge more often ...
