Carbon turnover and microbial activity in an artificial soil under imposed cyclic drainage and imbibition

Tatjana Milojevic

Water table fluctuations generate temporally and spatially dynamic physicochemical conditions that drive biogeochemical hot spots and hot moments in the vadose zone. However, their role in the cycling of soil C remains poorly known. Here, we present result ...

Microfluidic iMITOMI platform to study the architecture of low-affinity transcription factor binding site clusters

Ivan Istomin

Gene regulatory networks (GRNs) determine cellular behaviour, and ultimately the functioning of single- and multicellular organisms. Transcription factors regulate gene expression by binding to DNA or via remodelling chromatin. Recent advances in biotechno ...

Genomic Analysis of European Drosophila melanogaster Populations Reveals Longitudinal Structure, Continent-Wide Selection, and Previously Unknown DNA Viruses

Bart Deplancke

Genetic variation is the fuel of evolution, with standing genetic variation especially important for short-term evolution and local adaptation. To date, studies of spatiotemporal patterns of genetic variation in natural populations have been challenging, a ...

The N-Terminal Region of Yeast Protein Phosphatase Ppz1 Is a Determinant for Its Toxicity

Maria Lopez Malo

The Ppz enzymes are Ser/Thr protein phosphatases present only in fungi that are characterized by a highly conserved C-terminal catalytic region, related to PP1c phosphatases, and a more divergent N-terminal extension. In Saccharomyces cerevisiae, Ppz phosp ...

LPA1 receptor and chronic stress: Effects on behaviour and the genes involved in the hippocampal excitatory/inhibitory balance

Maria del Carmen Sandi Perez, Olivia Zanoletti, Alexandre Claude Gustave Bacq

The LPA1 receptor, one of the six characterized G protein-coupled receptors (LPA1–6) through which lysophosphatidic acid acts, is likely involved in promoting normal emotional behaviours. Current data suggest that the LPA-LPA1-receptor pathway may be invol ...

Rapid identification and interpretation of gene‐environment associations using the new R.SamBada landscape genomics pipeline

Stéphane Joost, Kevin Leempoel, Sylvie Stucki, Estelle Rochat, Oliver Michele Selmoni, Elia Vajana, Solange Catherine Gaillard

Samβada is a genome‐environment association (GEA) software, designed to search for signatures of local adaptation. However, pre‐ and post‐processing of data can be labour‐intensive, preventing wider uptake of the method. We have now developed R.SamBada, an ...

Mechanistic insights into AMP-activated protein kinase-dependent gene expression

Caterina Collodet

AMP-activated protein kinase (AMPK) is a fundamental enzyme that controls energy homeostasis, through orchestrating the cellular response to a reduction in energy availability. Under conditions of cellular energy stress AMPK senses the decrease in ATP leve ...

The Ovulatory Signal Precipitates LRH-1 Transcriptional Switching Mediated by Differential Chromatin Accessibility

Kristina Schoonjans

In the ovary, follicular growth and maturation are complicated processes that involve a series of morphological and physiological changes in oocytes and somatic cells leading to ovulation and luteinization, essential processes for fertility. Given the comp ...

Quantitative relationships between SMAD dynamics and target gene activation kinetics in single live cells

Felix Naef, David Michael Suter, Torgil Elias Friman, Onur Tidin

The transduction of extracellular signals through signaling pathways that culminate in a transcriptional response is central to many biological processes. However, quantitative relationships between activities of signaling pathway components and transcript ...

Systems genetics approaches to probe gene function

Hao Li

Genes are the functional units of heredity. However, the functions of many genes remain unknown, which impedes the understanding of the underlying mechanism of complex traits and diseases. Systems genetics approaches try to understand the complexity underl ...

Gene expression across mammalian organ development

Maria del Carmen Sandi Perez

The evolution of gene expression in mammalian organ development remains largely uncharacterized. Here we report the transcriptomes of seven organs (cerebrum, cerebellum, heart, kidney, liver, ovary and testis) across developmental time points from early or ...
