The cost of adaptability: resource availability constrains functional stability under pulsed disturbances

Global change exposes ecosystems to changes in the frequency, magnitude, and concomitancy of disturbances, which impact the composition and functioning of these systems. Here, we experimentally evaluate the effects of salinity disturbances and eutrophicati ...

DNA methylation sites in early adulthood characterised by pubertal timing and development: a twin study

Markus Kirolos Youssef

Background Puberty is a highly heritable and variable trait, with environmental factors having a role in its eventual timing and development. Early and late pubertal onset are both associated with various diseases developing later in life, and epigenetic c ...

The enhancement of DNA fragmentation in a bench top ultrasonic water bath with needle-induced air bubbles: Simulation and experimental investigation

Martinus Gijs, Thomas Lehnert, Yang Liu, Lin Sun

Shearing DNA to a certain size is the first step in many medical and biological applications, especially in next-generation gene sequencing technology. In this article, we introduced a highly efficient ultrasonic DNA fragmentation method enhanced by needle ...

Essential role of Cp190 in physical and regulatory boundary formation

Nicolas Jean Philippe Guex, Julien Dorier, Christian Iseli

Boundaries in animal genomes delimit contact domains with enhanced internal contact frequencies and have debated functions in limiting regulatory cross-talk between domains and guiding enhancers to target promoters. Most mammalian boundaries form by stalli ...

KRAB zinc finger protein-mediated control of transposon-embedded regulatory sequences from human germline to early embryos

Alexandra Iouranova

Transposable elements (TEs), also called jumping genes, are genetic elements capable of changing their position within the genome of their host. They make up large fractions of genomes, including 45% of human DNA content, according to current estimates. S ...

Confronting false discoveries in single-cell differential expression

Grégoire Courtine, Gioele La Manno, Quentin Barraud, Jordan Squair, Mark Andrew Anderson, Claudia Kathe, Nicholas David James, Matthieu Pierre Gautier, Michael Alexander Skinnider, Rémi Bernard René Hudelle, Thomas Haynes Hutson

Differential expression analysis of single-cell transcriptomics allows scientists to dissect cell-type-specific responses to biological perturbations. Here, the authors show that many commonly used methods are biased and can produce false discoveries. Diff ...

ZNF445 is a primary regulator of genomic imprinting

Didier Trono, Priscilla Turelli, Christian Axel Wandall Thorball, Evaristo Jose Planet Letschert, Sandra Eloise Kjeldsen, Michaël Imbeault, Andrea Coluccio

Genomic imprinting is an epigenetic process regulated by germline-derived DNA methylation, causing parental origin-specific monoallelic gene expression. Zinc finger protein 57 (ZFP57) is critical for maintenance of this epigenetic memory during post-fertil ...

DPPA2 and DPPA4 are necessary to establish a 2C‐like state in mouse embryonic stem cells

Didier Trono, Julien Léonard Duc, Alexandre Coudray, Alberto De Iaco

After fertilization of the transcriptionally silent oocyte, expression from both parental chromosomes is launched through zygotic genome activation (ZGA), occurring in the mouse at the 2-cell (2C) stage. Among the first elements to be transcribed are the D ...

Cell-Imprint Surface Modification by Contact Photolithography-Based Approaches: Direct-Cell Photolithography and Optical Soft Lithography Using PDMS Cell Imprints

Philippe Renaud, Harald Van Lintel, Shahin Bonakdar, Hanie Kavand

New cell-imprint surface modification techniques based on direct-cell photolithography and optical soft lithography using poly(dimethylsiloxane) (PDMS) cell imprints are presented for enhanced cell-based studies. The core concept of engineering materials f ...

BRB-seq: ultra-affordable high-throughput transcriptomics enabled by bulk RNA barcoding and sequencing

Bart Deplancke, David Hacker, Bastien Mangeat, Vincent Roland Julien Gardeux, Julie Marie Russeil, Daniel Alpern, Antonio Carlos Alves Meireles Filho

Despite its widespread use, RNA-seq is still too laborious and expensive to replace RT-qPCR as the default gene expression analysis method. We present a novel approach, BRB-seq, which uses early multiplexing to produce 3 cDNA libraries for dozens of sample ...
