Abstract:
Abstract Wrch1/RhoU is an atypical member of the Rho family. A major structural difference is the extended N-terminus of Wrch1 (nWrch1) containing three putative SH3 domain-binding motifs whose specificities are unknown. To define the impact of this extended region on coupling Wrch1 to cellular signaling, we analyzed in this study nWrch1 interaction with Src homology 3 (SH3) domains of different adaptor proteins. Using sedimentation and isothermal titration calorimetric (ITC) measurements, we identified isolated SH3 domains of growth factor receptor-bound protein 2 (Grb2), noncatalytic region

Abstract:
STAT3 (signal transducer and activator of transcription 3) is a transcription factor activated by cytokines, growth factors and oncogenes, whose activity is required for cell survival/proliferation of a wide variety of primary tumours and tumour cell lines. Prominent among its multiple effects on tumour cells is the stimulation of cell migration and metastasis, whose functional mechanisms are however not completely characterized. RhoU/Wrch1 (Wnt-responsive Cdc42 homologue) is an atypical Rho GTPase thought to be constitutively bound to GTP. RhoU was first identified as a Wnt-1-inducible mRNA a

Abstract:
L'épithélium intestinal se renouvelle tous les 4 à 6 jours chez les mammifères grâce aux cellules souches localisées au fond des cryptes. Le renouvellement dépend des signaux émis par le microenvironnement et requiert une phase de prolifération des cellules souches, de différenciation et d'apoptose/desquamation des cellules épithéliales. La signalisation Wnt, joue un rôle majeur dans l'homéostasie intestinale par l'action de deux gradients inversés le long de l'axe crypte/lumière ; la signalisation Wnt canonique, active au fond des cryptes, contrôle la prolifération alors que la signalisation
