Reproductive isolation arises during laboratory adaptation to a novel hot environment
Background: Reproductive isolation can result from adaptive processes (e.g., ecological speciation and mutation-order speciation) or stochastic processes such as "system drift" model. Ecological speciation predicts barriers to gene flow between populations ...
BMC2024Inheritance 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 drives oncogenic loss of chromatin segregation
Elisa Oricchio, Daniele Tavernari, Natalya Katanayeva, Ruxandra-Andreea Lambuta, Juan Diaz Miyar, Giovanni Ciriello
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 ...
NATURE PORTFOLIO2023Whole 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 ...
EPFL2023Genomic Analysis of European Drosophila melanogaster Populations Reveals Longitudinal Structure, Continent-Wide Selection, and Previously Unknown DNA Viruses
Genetic variation is the fuel of evolution, with standing genetic variation especially important for short-term evolution and local adaptation. To date, studies of spatiotemporal patterns of genetic variation in natural populations have been challenging, a ...
2020KAP1 facilitates reinstatement of heterochromatin after DNA replication
Didier Trono, Priscilla Turelli, Julien Léonard Duc, Sandra Eloise Kjeldsen, Annamaria Kauzlaric, Andrea Coluccio, Julien Paul André Pontis, Suk Min Jang, Benjamin Rauwel, Geneviève Almouzni
During cell division, maintenance of chromatin features from the parental genome requires their proper establishment on its newly synthetized copy. The loss of epigenetic marks within heterochromatin, typically enriched in repetitive elements, endangers ge ...
2018Signatures of selection and environmental adaptation across the goat genome post-domestication
Stéphane Joost, Estelle Rochat
Background: Since goat was domesticated 10,000 years ago, many factors have contributed to the differentiation of goat breeds and these are classified mainly into two types: (i) adaptation to different breeding systems and/or purposes and (ii) adaptation t ...
BMC2018A Fast and Exact Algorithm for the Exemplar Breakpoint Distance
A fundamental problem in comparative genomics is to compute the distance between two genomes. For two genomes without duplicate genes, we can easily compute a variety of distance measures in linear time, but the problem is NP-hard under most models when ge ...

A fundamental problem in comparative genomics is to compute the distance between two genomes. For two genomes without duplicate genes, we can easily compute a variety of distance measures in linear time, but the problem is NP-hard under most models when ge ...
Springer2015Centrosomes and cancer: revisiting a long-standing relationship
Over a century ago, centrosome aberrations were postulated to cause cancer by promoting genome instability. The mechanisms governing centrosome assembly and function are increasingly well understood, allowing for a timely reappraisal of this postulate. Thi ...
