Carrageenans are major gel forming polysaccharides in the extracellular matrix of the red macroalga Chondrus crispus. These galactans are made of linear chains of repetitive disaccharide motifs based on d-galactose residues alternately linked by β-1,4 and α-1,3 glycosidic bonds. A definite number…

Estimating consensus proteomes and metabolic functions from taxonomic affiliations

Arnaud Belcour, Pauline Hamon-Giraud, Alice Mataigne, Baptiste Ruiz, Yann Le Cunff, Jeanne Got, Lorraine Awhangbo, Megane Lebreton, Clémence Frioux, Simon Dittami, P. Dabert, Anne Siegel, Samuel Blanquart

Purpose: Metabarcoding, and metagenomic sequencing have enabled the characterization of highly diverse environmental communities. The challenge of estimating the metabolic functions carried out by these communities has led to the development of several state-of-the-art methods, most of which are…

Hormone-regulated dynamics of mRNA distribution on ribosomes in Sertoli cells

Xavier Leray, Julia Morales, Aurélie Tréfier, Kelly León, Thomas Bourquard, Astrid Musnier, Emmanuel Pecnard, Lucile Drobecq, Sandrine Boulben, Nicolas Azzopardi, Rémi Coulaud, Hamza Ouchène, Yan Jaszczyszyn, Eric Reiter, Florian Guillou, Lucie P Pellissier, Anne Poupon, Romain Yvinec, Pascale Crépieux

The effects of hormone stimulation on the cell translational profile remain poorly understood. Here, using polysome profiling combined to RNA sequencing, we analyzed the translational response to follicle-stimulating hormone (FSH) of primary rat Sertoli cells, that exhibit an active anabolic…
