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 ...

Loss of Bacterial Cell Pole Stabilization in Caulobacter crescentus Sensitizes to Outer Membrane Stress and Peptidoglycan-Directed Antibiotics

Gerardo Turcatti, Marc Chambon, Julien Bortoli Chapalay

Rod-shaped bacteria frequently localize proteins to one or both cellpoles in order to regulate processes such as chromosome replication or polar organ-elle development. However, the roles of polar factors in responses to extracellularstimuli have been gene ...

Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

Beat Fierz, Rudolf Hovius

The inner nuclear membrane is functionalized by diverse transmembrane proteins that associate with nuclear lamins and/or chromatin. When cells enter mitosis, membrane-chromatin contacts must be broken to allow for proper chromosome segregation; yet how thi ...

A high-content RNAi screen reveals multiple roles for long noncoding RNAs in cell division

Christina Ernst

Genome stability relies on proper coordination of mitosis and cytokinesis, where dynamic microtubules capture and faithfully segregate chromosomes into daughter cells. With a high-content RNAi imaging screen targeting more than 2,000 human lncRNAs, we iden ...

Observing protein interaction dynamics to chemically defined chromatin fibers by colocalization single-molecule fluorescence microscopy

Beat Fierz, Maxime Nicolas Mivelaz

In eukaryotic cells, the genome is packaged into chromatin and exists in different states, ranging from open euchromatic regions to highly condensed heterochromatic regions. Chromatin states are highly dynamic and are organized by an interplay of histone p ...

Structural and DNA binding properties of mycobacterial integration host factor mIHF

Stewart Cole, Giovanni Dietler, David Lyndon Emsley, Luciano Andres Abriata, Aleksandre Japaridze, Jérémie Piton, Nina Theres Odermatt, Rajkumar Singh

In bacteria, nucleoid associated proteins (NAPs) take part in active chromosome organization by supercoil management, three-dimensional DNA looping and direct transcriptional control. Mycobacterial integration host factor (mIHF, rv1388) is a NAP restricted ...

Revealing chromatin organization in metaphase chromosomes

Beat Fierz

The local structural organization of chromatin in mitotic chromosomes is not well understood. A new cryo-electron tomography study from the Daban laboratory (Chicano et al, ) reveals that mitotic chromatin isolated from human cells can assume a plate-like ...

Expression 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 ...

Functional analysis of the telomeric long non-coding RNA TERRA

Patricia Renck Nunes

Telomeres are nucleoprotein structures present in the end of linear chromosomes. In humans, a core complex of 6 proteins cap and protect the chromosome ends from being recognized as double-strand breaks and eliciting unwanted DNA damage and repair response ...

Infrared nanospectroscopic mapping of a single metaphase chromosome

Giovanni Dietler, Andrzej Kulik, Francesco Simone Ruggeri, Ewelina Wioletta Lipiec

The integrity of the chromatin structure is essential to every process occurring within eukaryotic nuclei. However, there are no reliable tools to decipher the molecular composition of metaphase chromosomes. Here, we have applied infrared nanospectroscopy ...

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 ...

Mitotic chromosome binding predicts transcription factor properties in interphase

Mahé Cécile Raccaud

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 ...
