TBX3 acts as tissue-specific component of the Wnt/beta-catenin transcriptional complex

BCL9 and PYGO are beta-catenin cofactors that enhance the transcription of Wnt target genes. They have been proposed as therapeutic targets to diminish Wnt signaling output in intestinal malignancies. Here we find that, in colorectal cancer cells and in de ...

Plastic and genetic responses of a common sedge to warming have contrasting effects on carbon cycle processes

Luca Bragazza, Constant Signarbieux

Climate warming affects plant physiology through genetic adaptation and phenotypic plasticity, but little is known about how these mechanisms influence ecosystem processes. We used three elevation gradients and a reciprocal transplant experiment to show th ...

Blacklisting variants common in private cohorts but not in public databases optimizes human exome analysis

Jacques Fellay, Alessandro Borghesi

Computational analyses of human patient exomes aim to filter out as many nonpathogenic genetic variants (NPVs) as possible, without removing the true disease-causing mutations. This involves comparing the patient's exome with public databases to remove rep ...

Functional characterization of 3D protein structures informed by human genetic diversity

Istvan Bartha

Sequence variation data of the human proteome can be used to analyze 3D protein structures to derive functional insights. We used genetic variant data from nearly 140,000 individuals to analyze 3D positional conservation in 4,715 proteins and 3,951 homolog ...

A comprehensive assessment of demographic, environmental, and host genetic associations with gut microbiome diversity in healthy individuals

Jacques Fellay, Christian Hammer, Flavia Aurelia Shoko Hodel, Petar Scepanovic

Background The gut microbiome is an important determinant of human health. Its composition has been shown to be influenced by multiple environmental factors and likely by host genetic variation. In the framework of the Milieu Interieur Consortium, a total ...

Simultaneous preservation of the DNA quality, the community composition and the density of freshwater oligochaetes for the development of genetically based biological indices

Régis Lionel Vivien

Introduction. Oligochaetes are recognized as valuable bioindicators of sediment quality in streams and lakes. The development of an oligochaete index based on the identification of specimens using DNA barcodes requires a method for simultaneously preservin ...

Label-free detection of hypoxia-induced extracellular vesicle secretion from MCF-7 cells

Philippe Renaud, Sandro Carrara, Tugba Kilic

Nanoscale extracellular vesicles (EVs) including exosomes (50–150 nm membrane particles) have emerged as promising cancer biomarkers due to the carried genetic information about the parental cells. However the sensitive detection of these vesicles remains ...

Maturing Mycobacterium smegmatis peptidoglycan requires non-canonical crosslinks to maintain shape

Georg Fantner, John McKinney, Haig Alexander Eskandarian

In most well-studied rod-shaped bacteria, peptidoglycan is primarily crosslinked by penicillin-binding proteins (PBPs). However, in mycobacteria, crosslinks formed by L,D-transpeptidases (LDTs) are highly abundant. To elucidate the role of these unusual cr ...

The ultimate and proximate mechanisms driving the evolution of long tails in forest deer mice

Susanne Petra Pfeifer

Understanding both the role of selection in driving phenotypic change and its underlying genetic basis remain major challenges in evolutionary biology. Here, we use modern tools to revisit a classic system of local adaptation in the North American deer mou ...

Persistence of butterfly populations in fragmented habitats along urban density gradients: motility helps

Stéphane Joost, Estelle Rochat, Ivo Widmer

In a simulation study of genotypes conducted over 100 generations for more than 1600 butterfly’s individuals, we evaluate how the increase of anthropogenic fragmentation and reduction of habitat size along urbanisation gradients (from 7% to 59% of impervio ...

The genomic landscape of human cellular circadian variation points to a novel role for the signalosome

Frédéric Bruno Martin Gachon, Konstantin Popadin, Daniel Alain Dominique Marie Mauvoisin

The importance of natural gene expression variation for human behavior is undisputed, but its impact on circadian physiology remains mostly unexplored. Using umbilical cord fibroblasts, we have determined by genome-wide association how common genetic varia ...

Miniaturized single-cell analyses for biomedical applications

Loïc Arvind Roger Arm

Numerous diseases affecting living beings have as a cause a modification of gene expression resulting in anomalous expression of proteins in up- or down-regulated fashion, with altered functions or expression of proteins that are not present in the cell in ...
