Journal ArticleDOI
Mutation in TET2 in Myeloid Cancers
François Delhommeau,Sabrina Dupont,Véronique Della Valle,Chloé James,Séverine Trannoy,Aline Massé,Olivier Kosmider,Jean-Pierre Le Couedic,Fabienne Robert,Antonio José Alberdi,Yann Lécluse,Isabelle Plo,François Dreyfus,Christophe Marzac,Nicole Casadevall,Catherine Lacombe,Serge Romana,Philippe Dessen,Jean Soulier,Franck Viguié,Michaela Fontenay,William Vainchenker,Olivier Bernard +22 more
TL;DR: Somatic mutations in TET2 occur in about 15% of patients with various myeloid cancers and were present in hematopoietic stem cells and preceded the JAK2 V617F mutation in the five samples from patients with myeloproliferative disorders that were analyzed.
Journal ArticleDOI
Mushroom body efferent neurons responsible for aversive olfactory memory retrieval in Drosophila
Julien Séjourné,Pierre-Yves Plaçais,Yoshinori Aso,Igor Siwanowicz,Séverine Trannoy,Vladimiros Thoma,Stevanus Rio Tedjakumala,Gerald M. Rubin,Paul Tchénio,Kei Ito,Guillaume Isabel,Hiromu Tanimoto,Thomas Preat +12 more
TL;DR: It is found that MB-V2 neurons were essential for retrieval of both short- and long-lasting memory, but not for memory formation or memory consolidation.
Journal ArticleDOI
Slow oscillations in two pairs of dopaminergic neurons gate long-term memory formation in Drosophila
Pierre-Yves Plaçais,Séverine Trannoy,Guillaume Isabel,Guillaume Isabel,Yoshinori Aso,Igor Siwanowicz,Ghislain Belliart-Guérin,Philippe Vernier,Serge Birman,Hiromu Tanimoto,Thomas Preat +10 more
TL;DR: The role of Drosophila dopaminergic neurons is examined and it is found that they act as a switch between two exclusive consolidation pathways leading to LTM or anesthesia-resistant memory (ARM).
Journal ArticleDOI
Two Independent Mushroom Body Output Circuits Retrieve the Six Discrete Components of Drosophila Aversive Memory
TL;DR: This work has identified a specific pair of MB efferent neurons that retrieve memory from γ KCs, and revealed that six discrete memory phases actually exist, three of which have been conflated in the past.
Journal ArticleDOI
The steroid hormone receptor EcR finely modulates Drosophila lifespan during adulthood in a sex-specific manner.
Hervé Tricoire,Valentine Battisti,Séverine Trannoy,Christelle Lasbleiz,Anne-Marie Pret,Véronique Monnier +5 more
TL;DR: A mild ubiquitous inactivation of EcR during adulthood was sufficient to slow the aging of male flies, whereas a stronger EcR inactivation decreased longevity, revealing a complex adult and sex-specific control of lifespan by steroid signalling in Drosophila.
