Role of polycomb in the control of transposable elements
Image is not available

This opinion piece reviews for the first time the evidences across kingdoms that Polycomb (PcG) Repressive Complex 2, thought to be dedicated to the epigenetic silencing of protein-coding genes, can also target, and even silence, transposable elements: could an ancestral role of PcG proteins be to silence transposable elements?

Presence of 2-hydroxymyristate on endotoxins is associated with death in
neonates with Enterobacter cloacae complex septic shock
Image is not available

This is the first published evidence linking lipopolysaccharide structural moiety to neonatal sepsis outcome and opens the possibility of using the 2-hydroxymyristate marker as a detection tool for high-risk patients, which could help reduce their mortality.

Macromolecular interactions in vitro, comparing classical and novel approaches
Image is not available

In a study published in European Biophysics Journal, two teams of the B3S department (INTGEN and MIP) with the PIM platform, in collaboration with national and international experts on molecular scale biophysics compare six approches to measure macromolecular interactions in vitro. The results were obtained in the context of a Training School (ARBRE-MOBIEU COST Action) organized in 2019 in our institute.
