Transcriptomic profiling of murine GnRH neurons reveals developmental trajectories linked to human reproduction and infertility

Bart Deplancke, Julie Marie Russeil, Daniel Alpern, Vincent Roland Julien Gardeux

Rationale: Neurons producing Gonadotropin-Releasing Hormone (GnRH) are essential for human reproduction and have to migrate from nose to brain during prenatal life. Impaired GnRH neuron biology results in alterations of the reproductive axis, including del ...

Mammalian adipogenesis regulator (Areg) cells use retinoic acid signalling to be non- and anti-adipogenic in age-dependent manner

Bart Deplancke, Pernille Yde Rainer, Radiana Ferrero, Julie Marie Russeil, Horia Hashimi, Magda Zachara, Daniel Alpern, Maria Litovchenko

Adipose stem and precursor cells (ASPCs) give rise to adipocytes and determine the composition and plasticity of adipose tissue. Recently, several studies have demonstrated that ASPCs partition into at least three distinct cell subpopulations, including th ...

A leukemia-protective germline variant mediates chromatin module formation via transcription factor nucleation

Freddy Radtke, Ute Koch, Bart Deplancke, Riccardo Dainese, Julie Marie Russeil, Daniel Alpern, Vincent Roland Julien Gardeux, Maria Litovchenko, Gerard Llimos Aubach, Jörn Pezoldt, Judith Franziska Kribelbauer

Non-coding variants coordinate transcription factor (TF) binding and chromatin mark enrichment changes over regions spanning >100 kb. These molecularly coordinated regions are named "variable chromatin modules" (VCMs), providing a conceptual framework of h ...

Disparate temperature-dependent virus-host dynamics for SARS-CoV-2 and SARS-CoV in the human respiratory epithelium

Bastien Mangeat, Bart Deplancke, Julie Marie Russeil, Daniel Alpern, Vincent Roland Julien Gardeux, Elisa Cora, Jörn Pezoldt

Since its emergence in December 2019, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has spread globally and become a major public health burden. Despite its close phylogenetic relationship to SARS-CoV, SARS-CoV-2 exhibits increased human-to- ...

The Hippo pathway controls myofibril assembly and muscle fiber growth by regulating sarcomeric gene expression

Bart Deplancke, Julie Marie Russeil, Daniel Alpern

Skeletal muscles are composed of gigantic cells called muscle fibers, packed with force-producing myofibrils. During development, the size of individual muscle fibers must dramatically enlarge to match with skeletal growth. How muscle growth is coordinated ...

Mitochondrial gene signature in the prefrontal cortex for differential susceptibility to chronic stress

Maria del Carmen Sandi Perez, Rolf Gruetter, Bart Deplancke, Antoine Timothée Cherix, Jocelin Grosse, Julie Marie Russeil, Daniel Alpern, Meltem Weger, Sriparna Ghosal

Mitochondrial dysfunction was highlighted as a crucial vulnerability factor for the development of depression. However, systemic studies assessing stress-induced changes in mitochondria-associated genes in brain regions relevant to depression symptomatolog ...

A parallelized, automated platform enabling individual or sequential ChIP of histone marks and transcription factors

Bart Deplancke, Antonio Carlos Alves Meireles Filho, Riccardo Dainese, Daniel Alpern, Vincent Roland Julien Gardeux, Gerard Llimos Aubach, Jia Yuan Jiang

Despite its popularity, chromatin immunoprecipitation followed by sequencing (ChIP-seq) remains a tedious (>2 d), manually intensive, low-sensitivity and low-throughput approach. Here, we combine principles of microengineering, surface chemistry, and molec ...

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

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

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 ...
