A developmental switch in the piRNA pathway ensures stage-specific transposon silencing

Thomas Høgsbro Grønbæk, Marianne Yoth, А. А. Ильин, Anja Ebert, Marina Giovannetti, Tamsin J. Samuels, Felipe Karam Teixeira, Peter Refsing Andersen

The paper shows the piRNA pathway in Drosophila undergoes a developmental switch to target different transposon families at distinct germline stages.

A histone methyltransferase-independent function of PRC2 controls small RNA dynamics during programmed DNA elimination in Paramecium

Caridad Miró-Pina, Olivia Charmant, Marina Giovannetti, Augustin de Vanssay, Andrea Frapporti, Adeline Humbert, Maoussi Lhuillier‐Akakpo, Guillaume Chevreux, Olivier Arnaiz, Sandra Duharcourt

The paper shows PRC2 controls small RNA dynamics during DNA elimination in Paramecium by selectively degrading non-TE scnRNAs, independent of its histone methyltransferase activity.

SIN-3 transcriptional coregulator maintains mitochondrial homeostasis and polyamine flux

Marina Giovannetti, María Jesús Rodríguez‐Palero, Paola Fabrizio, Ophélie Nicolle, Cécile Bedet, Grégoire Michaux, Michael A. Witting, Marta Artal‐Sanz, Francesca Palladino

This study shows that loss of SIN-3 in C. elegans disrupts mitochondrial function and metabolism, leading to mitochondrial fragmentation and altered metabolic flux.
