Journal ArticleDOI
Membrane organization and function of M1 and M23 isoforms of aquaporin-4 in epithelial cells
Claudia Silberstein,Richard Bouley,Yan Huang,Pingke Fang,Núria M. Pastor-Soler,Dennis Brown,Alfred N. Van Hoek +6 more
TL;DR: It is concluded that the higher-order organization of AQP4 in OAPs increases single-channel osmotic water permeability by one order of magnitude and that differential cellular expression levels of the two isoforms could regulate this organization.
Journal ArticleDOI
Postnatal Expression of Aquaporins in Epithelial Cells of the Rat Epididymis
Nicolas Da Silva,Claudia Silberstein,Valérie Beaulieu,Christine Piétrement,Alfred N. Van Hoek,Dennis Brown,Sylvie Breton +6 more
TL;DR: AQPs may be involved not only in the transepithelial transport of water in the epididymis but also in the postnatal development of this organ, as suggested by the differential expression of AQP2.
Journal ArticleDOI
Role of NHERF1, Cystic Fibrosis Transmembrane Conductance Regulator, and cAMP in the Regulation of Aquaporin 9
Christine Piétrement,Nicolas Da Silva,Claudia Silberstein,Marianne James,Mireille Marsolais,Alfred N. Van Hoek,Dennis Brown,Núria M. Pastor-Soler,Nadia Ameen,Raynald Laprade,Vijaya Ramesh,Sylvie Breton +11 more
TL;DR: It is proposed that CFTR is an important regulator of AQP9 and that the interaction between AQP 9, NHERF1, and CFTR may facilitate the activation of AQp9 by cAMP.
Journal ArticleDOI
Functional characterization and localization of AQP3 in the human colon
TL;DR: Immunocytochemistry and immunofluorescence studies in human colon revealed that the AQP3 protein is restricted to the villus epithelial cells, suggesting that AQP 3 is implicated in water absorption across human colonic surface cells.
Journal ArticleDOI
Cytotoxic effect of Shiga toxin-2 holotoxin and its B subunit on human renal tubular epithelial cells.
TL;DR: The cytotoxicity of Stx type 2 (Stx2 holotoxin) and its B subunit ( Stx2 B sub unit) on human renal tubular epithelial cells (HRTEC) in the presence and absence of inflammatory factors is examined.
