Publikováno v: Journal of Biological Chemistry. 280:28601-28609

We have cloned two new triadin isoforms from rat skeletal muscle, Trisk 49 and Trisk 32, which were named according to their theoretical molecular masses (49 and 32 kDa, respectively). Specific antibodies directed against each protein were produced t

Maurocalcine (MCa), a 33 amino acid toxin obtained from scorpion venom, has been shown to interact with the isolated skeletal-type ryanodine receptor (RyR1) and to strongly modify its calcium channel gating. In this study, we explored the effects of

Junctate is a key element in calcium entry induced by activation of InsP3 receptors and/or calcium store depletion

Publikováno v: The Journal of Cell Biology

In many cell types agonist-receptor activation leads to a rapid and transient release of Ca2+ from intracellular stores via activation of inositol 1,4,5 trisphosphate (InsP3) receptors (InsP3Rs). Stimulated cells activate store- or receptor-operated

Human skeletal muscle triadin: gene organization and cloning of the major isoform, Trisk 51

Autor: Séverine Groh, Norma B. Romero, Michel Villaz, Joelle Henry-Berger, Dominique Thevenon, Michel DeWaard, Isabelle Marty, Sophia Smida-Rezgui, Frédéric Chevessier

Publikováno v: Biochemical and Biophysical Research Communications. 303:669-675

We obtained the gene organization of human triadin gene by aligning the DNA coding sequence of human 95-kDa triadin (Trisk 95) with human genomic database. We identified a novel human triadin isoform, a potential human homologue of rat Trisk 51. We s

Up-regulation of α2β1 integrin cell-surface expresssion protects A431 cells from epidermal growth factor-induced apoptosis

Autor: Jean-Baptiste Rognoni, Pierre-Marie Martin, Stéphane Honoré, Claude Penel, Sophia Smida Rezgui

Publikováno v: International Journal of Cancer. 87:360-367

High epidermal growth factor (EGF) concentration (10–8 M) induces inhibition of A431 cell proliferation, resulting in part from an apoptotic process. For some cells escaping this process, proliferation was associated with a decrease in apoptosis. M

Transduction of the scorpion toxin maurocalcine into cells. Evidence that the toxin crosses the plasma membrane

Maurocalcine (MCa) is a 33 amino acid residue peptide toxin isolated from the scorpion Scorpio maurus palmatus. External application of MCa to cultured myotubes is known to produce Ca2+ release from intracellular stores. MCa binds directly to the ske

Monolayer versus aggregate balance in survival process for EGF-induced apoptosis in A431 carcinoma cells: Implication of ROS-P38 MAPK-integrin alpha2beta1 pathway

A431 cells escape EGF-induced apoptosis by forming cell aggregates. We show that these clusters migrate and merge with neighboring ones, resulting in larger structures composed of a multilayer central (3D) population surrounded by a cell monolayer (2
