Inheritance of H3K9 methylation regulates genome architecture in Drosophila early embryos

Fides Zenk

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 ( ...

Species-specific regulation of XIST by the JPX/FTX orthologs

Olga Marie Louise Rosspopoff

X chromosome inactivation (XCI) is an essential process, yet it initiates with remarkable diversity in various mammalian species. XIST, the main trigger of XCI, is controlled in the mouse by an interplay of lncRNA genes (LRGs), some of which evolved concom ...

Whole genome doubling promotes tumorigenesis through loss of chromatin segregation and compartment repositioning

Ruxandra-Andreea Lambuta

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 ...

SMCHD1 promotes ATM-dependent DNA damage signaling and repair of uncapped telomeres

Joachim Lingner, Wareed Ahmed, Marianna Feretzaki, Verena Pfeiffer, Aleksandra Vancevska

Structural maintenance of chromosomes flexible hinge domain-containing protein 1 (SMCHD1) has been implicated in X-chromosome inactivation, imprinting, and DNA damage repair, and mutations in SMCHD1 can cause facioscapulohumeral muscular dystrophy. More re ...

Gender medicine and oncology: report and consensus of an ESMO workshop

Jacques Fellay

Background: The importance of sex and gender as modulators of disease biology and treatment outcomes is well known in other disciplines of medicine, such as cardiology, but remains an undervalued issue in oncology. Considering the increasing evidence for t ...

The telomeric DNA damage response: Insights into telomere compaction and identification of novel damage signaling factors

Aleksandra Vancevska

Telomeres are dynamic nucleo-protein structures capping the ends of all eukaryotic chromosomes. Together with telomerase, they counteract replication-dependent telomere attrition. Additionally, they disguise the linear ends of the chromosome from the DNA d ...

Male-killing symbiont damages host's dosage-compensated sex chromosome to induce embryonic apoptosis

Bruno Lemaitre, Toshiyuki Harumoto

Some symbiotic bacteria are capable of interfering with host reproduction in selfish ways. How such bacteria can manipulate host's sex-related mechanisms is of fundamental interest encompassing cell, developmental and evolutionary biology. Here, we uncover ...

Replication of Telomeres and the Regulation of Telomerase

Joachim Lingner, Verena Pfeiffer

Telomeres are the physical ends of eukaryotic chromosomes. They protect chromosome ends from DNA degradation, recombination, and DNA end fusions, and they are important for nuclear architecture. Telomeres provide a mechanism for their replication by semico ...

A new genomic evolutionary model for rearrangements, duplications, and losses that applies across eukaryotes and prokaryotes

Bernard Moret, Yu Lin

Genomic rearrangements have been studied since the beginnings of modern genetics and models for such rearrangements have been the subject of many papers over the last 10 years. However, none of the extant models can predict the evolution of genomic organiz ...

Use of igf-1 and nt-3 in the treatment of x-linked adrenoleukodystrophy

Patrick Aebischer, Jean-Charles Bensadoun

The present invention is directed to new compositions uses thereof and related methods for the treatment of X- linked adrenoleukodystrophy. ...

Insulin-like growth factor-1 and neurotrophin-3 gene therapy prevents motor decline in an X-linked adrenoleukodystrophy mouse model

Patrick Aebischer, Jean-Charles Bensadoun

X-linked adrenoleukodystrophy (X-ALD) is the most common inherited peroxisomal disorder characterized by a progressive demyelination of the central nervous system. The marked loss of myelin and oligodendrocytes observed in the disease prompted us to evalua ...

Ectopic nuclear reorganisation driven by a Hoxb1 transgene transposed into Hoxd

Denis Duboule

The extent to which the nuclear organisation of a gene impacts on its ability to be expressed, or whether nuclear organisation merely reflects gene expression states, remains an important but unresolved issue. A model system that has been instrumental in i ...

Invasion an fixation of sex-reversal genes

Séverine Vuilleumier Varisco

We simulated a meta-population with random dispersal among demes but local mating within demes to investigate conditions under which a dominant female-determining gene W, with no individual selection advantage, can invade and become fixed in females, chang ...

Genetic characterization of CHO production host DG44 and derivative recombinant cell lines

Florian Maria Wurm, David Hacker, Madiha Derouazi, Martin Bertschinger

The dihydrofolate reductase-deficient Chinese hamster ovary (CHO) cell line DG44 is the dominant mammalian host for recombinant protein manufacturing, in large part because of the availability of a well-characterized genetic selection and amplification sys ...
