Tuning SAS-6 architecture with monobodies impairs distinct steps of centriole assembly

Pierre Gönczy, Georg Fantner, Oliver Hantschel, Santiago Harald Andany, Niccolo Banterle, Virginie Hamel, Georgios Hatzopoulos, Tatiana Favez

Centrioles are evolutionarily conserved multi-protein organelles essential for forming cilia and centrosomes. Centriole biogenesis begins with self-assembly of SAS-6 proteins into 9-fold symmetrical ring polymers, which then stack into a cartwheel that sca ...

The human telomeric proteome during telomere replication

Joachim Lingner, Aleksandra Vancevska, Thomas Frédéric Lunardi, Gérald Joseph Paul Lossaint, Chih-Yi Gabriela Lin

Telomere shortening can cause detrimental diseases and contribute to aging. It occurs due to the end replication problem in cells lacking telomerase. Furthermore, recent studies revealed that telomere shortening can be attributed to difficulties of the sem ...

Computational identification and experimental characterization of preferred downstream positions in human core promoters

Philipp Bucher, René Dreos

Author summary Transcription of genes by the RNA polymerase II enzyme initiates at a genomic region termed the core promoter. The core promoter is a regulatory region that may contain diverse short DNA sequence motifs/elements that confer specific properti ...

Toward a mechanistic understanding of variable chromatin modules

Gerard Llimos Aubach

Our genome is a long sequence of DNA that contains all the information to be able to constitute a living organism like us, similarly to what the letters in a book do to create a story. This sequence, which is a stretch of molecules called nucleotides, is a ...

High throughput screening identifies SOX2 as a super pioneer factor that inhibits DNA methylation maintenance at its binding sites

Ludovica Vanzan

Binding of mammalian transcription factors (TFs) to regulatory regions is hindered by chromatin compaction and DNA methylation of their binding sites. Nevertheless, pioneer transcription factors (PFs), a distinct class of TFs, have the ability to access nu ...

Nucleosome Binding by the Lysine Specific Demethylase 1 (LSD1) Enzyme Enables Histone H3 Demethylation

Beat Fierz, Aurore Marie-France Delachat

The essential human enzyme lysine specific demethylase 1 (LSD1) silences genes by demethylating mono- and dimethylated lysine 4 in histone H3 (H3K4me1/2). Studies of the minimal requirements for LSD1 activity are complicated by the heterogeneity of histone ...

NCoR1 Protects Mice From Dextran Sodium Sulfate Induced Colitis by Guarding Colonic Crypt Cells From Luminal Insult

Johan Auwerx

BACKGROUND & AIMS: Colonic stem cells are essential for producing the mucosal lining, which in turn protects stem cells from insult by luminal factors. Discovery of genetic and biochemical events that control stem cell proliferation and differentiation can ...

Cognitive epigenetic priming: leveraging histone acetylation for memory amelioration

Johannes Gräff, Allison Marie Burns

Multiple studies have found that increasing histone acetylation by means of histone deacetylase inhibitor (HDACi) treatment can ameliorate memory and rescue cognitive impairments, but their mode of action is not fully understood. In particular, it is uncle ...

The Gene-Regulatory Footprint of Aging Highlights Conserved Central Regulators

Johan Auwerx, Maroun Bou Sleiman, Richardus Houtkooper, Xu Wang, Pooja Jha

Many genes and pathways have been linked to aging, yet our understanding of underlying molecular mechanisms is still lacking. Here, we measure changes in the transcriptome, histone modifications, and DNA methylome in three metabolic tissues of adult and ag ...

The role of histone tails in nucleosome stability: An electrostatic perspective

Alessandro Samuele Patelli

We propose a methodology for the study of protein-DNA electrostatic interactions and apply it to clarify the effect of histone tails in nucleosomes. This method can be used to correlate electrostatic interactions to structural and functional features of pr ...

Development of chemical biology tools to reveal the function and organization of the silenced chromatin state

Nora Guidotti

Effector proteins are recruited to chromatin via transient interactions between their reader domains and histone post-translational modification (PTM) patterns. These interactions form signaling pathways that control gene expression or repression and which ...

Computational characterisation of the selectivity and binding mode of mono- and binuclear transition metal based anticancer compounds

Thibaud Edouard Alistair von Erlach

The rising resistance and the severe side effects associated with classical anticancer drugs such as cisplatin or mercaptopurines has triggered the development of novel antitumourous agents based on transition metal (e.g. ruthenium, osmium, and gold) organ ...
