Whole-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 ...

Histone acetylation dynamics modulates chromatin conformation and allele-specific interactions at oncogenic loci

Elisa Oricchio, Daniele Tavernari, Natalya Katanayeva, Stephanie Jocelyne Sungalee, Ruxandra-Andreea Lambuta, Giovanni Ciriello

In cancer cells, enhancer hijacking mediated by chromosomal alterations and/or increased deposition of acetylated histone H3 lysine 27 (H3K27ac) can support oncogene expression. However, how the chromatin conformation of enhancer-promoter interactions is a ...

Mesomelic dysplasias associated with the HOXD locus are caused by regulatory reallocations

Denis Duboule, Lucille Delisle, Christopher Chase Bolt

Mesomelic dysplasia, a severe shortening and bending of the limb, has been linked to rearrangements in the HoxD cluster in humans and mice. Here the authors engineer a 1 Mb inversion including the HoxD gene cluster and use this model to provide a mechanist ...

Genome-wide Screens Implicate Loss of Cullin Ring Ligase 3 in Persistent Proliferation and Genome Instability in TP53-Deficient Cells

Sebastian Martin Waszak, Ruxandra-Andreea Lambuta

TP53 deficiency is the most common alteration in cancer; however, this alone is typically insufficient to drive tumorigenesis. To identify genes promoting tumorigenesis in combination with TP53 deficiency, we perform genome-wide CRISPR-Cas9 knockout screen ...

Effect of Fc Receptor Genetic Diversity on HIV-1 Disease Pathogenesis

Jacques Fellay, Christian Axel Wandall Thorball

Fc receptor (FcR) genes collectively have copy number and allelic polymorphisms that have been implicated in multiple inflammatory and autoimmune diseases. This variation might also be involved in etiology of infectious diseases. The protective role of Fc- ...

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 ...

Functional Dissection of Intersubunit Interactions in the EspR Virulence Regulator of Mycobacterium tuberculosis

Stewart Cole, Giovanni Dietler, Matteo Dal Peraro, Florence Pojer, Marco Stenta, Aleksandre Japaridze, Benjamin Blasco, Basile Isidore Martin Wicky

The nucleoid-associated protein EspR, a chromosome organizer, has pleiotropic effects on expression of genes associated with cell wall function and pathogenesis in Mycobacterium tuberculosis. In particular, EspR binds to several sites upstream of the espAC ...

Multiscale Spatial Organization of RNA Polymerase in Escherichia coli

Seamus John Holden

Nucleic acid synthesis is spatially organized in many organisms. In bacteria, however, the spatial distribution of transcription remains obscure, owing largely to the diffraction limit of conventional light microscopy (200-300 nm). Here, we use photoactiva ...

A novel homozygous R764H mutation in crumbs homolog 1 causes autosomal recessive retinitis pigmentosa

Purpose: Retinitis pigmentosa (RP; MIM 268000) is a hereditary disease characterized by poor night vision and progressive loss of photoreceptors, eventually leading to blindness. This degenerative process primarily affects peripheral vision due to the loss ...

The Wnt inhibitory factor 1 (WIF1) is targeted in glioblastoma and has a tumor suppressing function potentially by induction of senescence

Mauro Delorenzi

Gene expression-based prediction of genomic copy number aberrations in the chromosomal region 12q13 to 12q15 that is flanked by MDM2 and CDK4 identified Wnt inhibitory factor 1 (WIF1) as a candidate tumor suppressor gene in glioblastoma. WIF1 encodes a sec ...
