Epigenetic and tumorigenicity

The team of Hervé Chneiweiss and Marie-Pierre Junier has just shown the key role that the ARNT2 transcription factor plays in the level of aggression of brain tumour cells. This was done by analysing chromatin epigenetic modifications. [...]

The P-bodies finally identifies within eukaryotic cells

Dominique Weil's team recently published in the Molecular Cell journal a pioneering study describing the purification and analysis of P-bodies (P for "processing"), which are droplets of RNA and proteins that condense in the cytoplasm of eukaryotic cells. [...]

The kinase Mps1 is required to generate oocytes with the correct chromosome count for fertilisation

Katja Wassmann's team at the IBPS recently published a study in Nature Communications in which they tried to gain a better understanding of the molecular mechanisms underlying chromosome segregation among mammalian oocytes. [...]

New regulators of hematopoietic stem cells identified

Charles Durand and Thierry Jaffredo at the IBPS (UMR 7622) recently showed in The Journal of Cell Biology that stromal cells, known to regulate hematopoietic stem cells (HSCs), secrete extracellular vesicles (EVs) specifically captured by HSCs. [...]

When exposure to phthalates disturbs mouse sexual communication

Sakina Mhaouty-Kodja's team at the Institute of Biology Paris-Seine published results in Environmental Health Perspectives showing that male adult mice chronically exposed to low doses of DEHP emit less ultrasonic vocalisations in the presence of sexually receptive females. [...]

A role for mechanics in the construction of neuronal circuits

In a study published in Nature Communications, Marie Breau, a IBPS researcher from Sylvie Schneider-Maunoury’s team, found out that the axons of the zebrafish olfactory sensory neurons, which establish connections with the brain, elongate through an original mechanism involving mechanical forces exerted on the neurons. [...]


Hommage à Véronique Soulier

C’est avec une immense tristesse que nous avons appris le décès de Véronique Soulier (récemment devenue Madame Moison), survenu le lundi 17 juillet. Véronique a assumé la responsabilité administrative et financière de l’IBPS de juillet 2014 à juillet 2015.

Smoking would increase sensitivity to stress

Researchers from the Institute of Biology Paris-Seine (Neuroscience Paris-Seine) and the Institut de Pharmacologie Moléculaire & Cellulaire (Sophia Antipolis, Valbonne) have investigated the relationship between stress and nicotine. and show that smoking increases sensitivity to stress, due to an action on a7 nicotinic receptors. These results have been published in Molecular Psychiatry. [...]

A new diagnostic marker for cardiovascular diseases

In a recent article published in Circulation, the team of Mustapha Rouis at the Institute of Biology Paris-Seine has identified the thioredoxin-80 (TRX-80) as a new marker for inflammatory and cardiovascular diseases (CVD). The team showed that the concentration of this protein in the blood increased with age. [...]
