Genomic Instability Profiles at the Single Cell Level in Mouse Colorectal Cancers of Defined Genotypes

Maxim Norkin, Jörg Hülsken, Paloma Ordonez Moran

The genomes of many human CRCs have been sequenced, revealing a large number of genetic alterations. However, the molecular mechanisms underlying the accumulation of these alterations are still being debated. In this study, we examined colorectal tumours t ...

Improvement of breast cancer diagnosis through microfluidics

Huu Tuan Nguyen

In breast cancer, 15-20% of cases are reported with overexpression of human epidermal growth factor receptor 2 (HER2) that causes rapid cancer progression and poor prognosis. Fortunately, HER2-targeted therapy using specific antibodies such as Trastuzumab ...

Genetic and epigenetic inactivation of SESTRIN1 controls mTORC1 and response to EZH2 inhibition in follicular lymphoma

Elisa Oricchio, Natalya Katanayeva, Elena Battistello, Maria Christine Donaldson, Stephanie Jocelyne Sungalee, Giovanni Ciriello

Follicular lymphoma (FL) is an incurable form of B cell lymphoma. Genomic studies have cataloged common genetic lesions in FL such as translocation t(14;18), frequent losses of chromosome 6q, and mutations in epigenetic regulators such as EZH2 Using a focu ...

User-Friendly Image-Based Segmentation and Analysis of Chromosomes

Michaël Unser, Florian Maria Wurm, Lucia Baldi Unser, Ricard Delgado Gonzalo, Virginie Sophie Uhlmann

We designed two efficient and user-friendly tools for the segmentation and analysis of images containing chromosomes or, more generally, rod-shaped elements that are spread on microscopic slides. The segmentation tool allows to automatically extract the pr ...

The 16p11.2 locus modulates brain structures common to autism, schizophrenia and obesity

Nouchine Hadjikhani, Loyse Hippolyte

Anatomical structures and mechanisms linking genes to neuropsychiatric disorders are not deciphered. Reciprocal copy number variants at the 16p11.2 BP4-BP5 locus offer a unique opportunity to study the intermediate phenotypes in carriers at high risk for a ...

Natural variation in genome architecture among 205 Drosophila melanogaster Genetic Reference Panel lines

Bart Deplancke, Andreas Massouras, Sandy Lee, Yi Han, Yiming Zhu

The Drosophila melanogaster Genetic Reference Panel (DGRP) is a community resource of 205 sequenced inbred lines, derived to improve our understanding of the effects of naturally occurring genetic variation on molecular and organismal phenotypes. We used a ...

Genomic Variation and Its Impact on Gene Expression in Drosophila melanogaster

Bart Deplancke, Andreas Massouras, Sebastian Martin Waszak, Jeffrey David Jensen, Monica Albarca Aguilera

Understanding the relationship between genetic and phenotypic variation is one of the great outstanding challenges in biology. To meet this challenge, comprehensive genomic variation maps of human as well as of model organism populations are required. Here ...

A SP1/MIZ1/MYCN Repression Complex Recruits HDAC1 at the TRKA and p75NTR Promoters and Affects Neuroblastoma Malignancy by Inhibiting the Cell Response to NGF

Antonio Porro

Neuroblastoma is the most common extracranial solid tumor of childhood. One important factor that predicts a favorable prognosis is the robust expression of the TRKA and p75NTR neurotrophin receptor genes. Interestingly, TRKA and p75NTR expression is often ...

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 ...

Chromosomal Number Aberrations and Transformation in Adult Mouse Retinal Stem Cells In Vitro

Freddy Radtke, Ivan Stamenkovic

Purpose. The potential of stem cells (SCs) as a source for cell-based therapy on a wide range of degenerative diseases and damaged tissues such as retinal degeneration has been recognized. Generation of a high number of retinal stem cells (RSCs) in vitro w ...

Lack of Insertional-Deletional Polymorphism in a Collection of Mycobacterium ulcerans Isolates from Ghanaian Buruli Ulcer Patients

Stewart Cole, Julia Hauser

Mycobacterium ulcerans causes the devastating infectious skin disease Buruli ulcer and has a monomorphic population structure. The resolution of conventional genetic fingerprinting methods is therefore not sufficient for microepidemiological studies aiming ...

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 ...

Détection des aberrations chromosomiques basée sur les profiles d'expression des gènes et les données aCGH

The detection of chromosomal aberrations constitutes an important stage in the comprehension of the pathogenesis of several diseases, as cancer. In this case, the amplification or deletion (suppression) of some chromosomal regions, was identified as being ...
