L'équipe de Sébastien Léon vient de publier un nouvel article dans PLOS Genetics, intitulé : 2-deoxyglucose transiently inhibits yeast AMPK signaling and triggers glucose transporter endocytosis, potentiating the drug toxicity   Abstract 2-deoxyglucose is a glucose analog that impacts many aspects of cellular physiology. After its uptake and its phosphorylation into 2-deoxyglucose-6-phosphate (2DG6P), it interferes with several metabolic…

Un nouvel article co-signé par la plateforme ProtéoSeine :   Cisplatin causes covalent inhibition of protein-tyrosine phosphatase 1B (PTP1B) through reaction with its active site cysteine: Molecular, cellular and in vivo mice studies Abstract Protein tyrosine phosphatase 1B (PTP1B) is a critical regulator of different signalling cascades such as the EGFR pathway. The biological importance of PTP1B is further…

Manon Monier et Virginie Courtier viennent de publier dans Insects une nouvelle revue : Drosophila Glue: A Promising Model for Bioadhesion Abstract The glue produced by Drosophila larvae to attach themselves to a substrate for several days and resist predation until the end of metamorphosis represents an attractive model to develop new adhesives for dry environments. The…

Féliciations à l'équipe Libri pour ce nouvel article publié dans Molecular Cell! Sen1 is a key regulator of transcription-driven conflicts   Summary Cellular homeostasis requires the coordination of several machineries concurrently engaged in the DNA. Wide-spread transcription can interfere with other processes, and transcription-replication conflicts (TRCs) threaten genome stability. The conserved Sen1 helicase not only terminates non-coding transcription but…
