Gallouzi, Imed-eddine, Parker, Fabienne, Chebli, Karim, Maurier, Florence, Labourier, Emmanuel, Barlat, Isabelle, ...

A potential p120 GTPase-activating protein (RasGAP) effector, G3BP (RasGAP Src homology 3 [SH3] binding protein), was previously identified based on its ability to bind the SH3 domain of RasGAP. Here...

Antagonism between RSF1 and SR proteins for both splice-site recognition in vitro and Drosophila development

Labourier, Emmanuel, Bourbon, Henri-Marc, Gallouzi, Imed-eddine, Fostier, Maggy, Allemand, Eric, Tazi, Jamal

Specific recognition of splice sites within metazoan mRNA precursors (pre-mRNAs) is a potential stage for gene regulation by alternative splicing. Splicing factors of the SR protein family play a...

NF-κB-Mediated MyoD Decay during Muscle Wasting Requires Nitric Oxide Synthase mRNA Stabilization, HuR Protein, and Nitric Oxide Release†

Di Marco, Sergio, Mazroui, Rachid, Dallaire, Patrice, Chittur, Sridar, Tenenbaum, Scott A., Radzioch, Danuta, ...

Muscle wasting (cachexia) is a consequence of chronic diseases, such as cancer, and is associated with degradation of muscle proteins such as MyoD. The cytokines tumor necrosis factor alpha and gamma...

Inhibition of the Ubiquitin-Proteasome System Induces Stress Granule Formation

Mazroui, Rachid, Di Marco, Sergio, Kaufman, Randal J., Gallouzi, Imed-Eddine

The inhibition of the ubiquitin-dependent proteasome system (UPS) via specific drugs is one type of approach used to combat cancer. Although it has been suggested that UPS inhibition prevents the...

Involvement of Transportin 2–mediated HuR Import in Muscle Cell Differentiation

Van Der Giessen, Kate, Gallouzi, Imed-Eddine

Muscle fiber formation requires the sequential expression of myogenic regulatory factors (MRFs) such as MyoD and myogenin. The messenger RNAs encoding these two proteins are regulated...

The RNA-Binding Protein HuR Promotes Cell Migration and Cell Invasion by Stabilizing the β-actin mRNA in a U-Rich-Element-Dependent Manner▿ †
