Single-mitosis dissection of acute and chronic DNA mutagenesis and repair

How chronic mutational processes and punctuated bursts of DNA damage drive evolution of the cancer genome is poorly understood. Here, we demonstrate a strategy to disentangle and quantify distinct mechanisms underlying genome evolution in single cells, dur ...

Memory and relatedness of transcriptional activity in mammalian cell lineages

Felix Naef, David Michael Suter, Nicholas Edward Phillips, Aleksandra Mandic, Saeed Omidi Klishami

Phenotypically identical mammalian cells often display considerable variability in transcript levels of individual genes. How transcriptional activity propagates in cell lineages, and how this varies across genes is poorly understood. Here we combine live- ...

A Modular Ligation Strategy for Asymmetric Bivalent Nucleosomes Trimethylated at K36 and K27

Beat Fierz, Nora Guidotti, Andreas Linus Bachmann, Carolin Christine Lechner

In nature, individual histones in the same nucleosome can carry identical (symmetric) or different (asymmetric) post-translational modification (PTM) patterns, increasing the combinatorial complexity. Embryonic stem cells exhibit bivalent nucleosomes, some ...

Transcription-induced supercoiling explains formation of self-interacting chromatin domains in S-pombe

Julien Dorier, Yannis Burnier, Fabrizio Benedetti, Andrzej Stasiak

The question of how self-interacting chromatin domains in interphase chromosomes are structured and generated dominates current discussions on eukaryotic chromosomes. Numerical simulations using standard polymer models have been helpful in testing the vali ...

Models that include supercoiling of topological domains reproduce several known features of interphase chromosomes

Julien Dorier, Yannis Burnier, Fabrizio Benedetti, Andrzej Stasiak

Understanding the structure of interphase chromosomes is essential to elucidate regulatory mechanisms of gene expression. During recent years, high-throughput DNA sequencing expanded the power of chromosome conformation capture (3C) methods that provide in ...

Tonotopic mapping of human auditory cortex

Melissa Saenz

Since the early days of functional magnetic resonance imaging (fMRI), retinotopic mapping emerged as a powerful and widely-accepted tool, allowing the identification of individual visual cortical fields and furthering the study of visual processing. In con ...

Mutual Inhibition Between the Anaphase-promoting Complex and the Spindle Assembly Checkpoint in C. Elegans Embryos

Alexandra Bezler

The cell cycle orchestrates timely duplication and distribution of cellular components to daughter cells. Checkpoints operate to survey the faithful completion of specific steps during the cell cycle, thus ensuring the equal segregation of genetic material ...

Mutual Antagonism Between the Anaphase Promoting Complex and the Spindle Assembly Checkpoint Contributes to Mitotic Timing in Caenorhabditis elegans

Pierre Gönczy, Alexandra Bezler

The anaphase promoting complex/cyclosome (APC/C) triggers the separation of sister chromatids and exit from mitosis across eukaryotic evolution. The APC/C is inhibited by the spindle assembly checkpoint (SAC) until all chromosomes have achieved bipolar att ...

Massive Gene Duplication Event among Clinical Isolates of the Mycobacterium tuberculosis W/Beijing Family

Gaëlle Séraphine Kolly

As part of our effort to uncover the molecular basis for the phenotypic variation among clinical Mycobacterium tuberculosis isolates, we have previously reported that isolates belonging to the W/Beijing lineage constitutively overexpress the DosR-regulated ...

A G2-phase microtubule-damage response in fission yeast

Fernando Romero Balestra

Microtubules assume a variety of structures throughout the different stages of the cell cycle. Ensuring the correct assembly of such structures is essential to guarantee cell division. During mitosis, it is well established that the spindle assembly checkp ...
