The eukaryote-specific N-terminal extension of ribosomal protein S31 contributes to the assembly and function of 40S ribosomal subunits

Fernández-Pevida, Antonio ; Martín-Villanueva, Sara ; Murat, Guillaume ; Lacombe, Thierry ; Kressler, Dieter ; Cruz, Jesús de la

In: Nucleic Acids Research, 2016, vol. 44, no. 16, p. 7777–7791

The archaea-/eukaryote-specific 40S-ribosomal-subunit protein S31 is expressed as an ubiquitin fusion protein in eukaryotes and consists of a conserved body and a eukaryote-specific N-terminal extension. In yeast, S31 is a practically essential protein, which is required for cytoplasmic 20S pre-rRNA maturation. Here, we have studied the role of the N-terminal extension of the yeast S31...

Early effects of carbachol on the morphology of motor endplates of mammalian skeletal muscle fibers

Voigt, Tilman

In: Muscle & Nerve, 2010, vol. 41, no. 3, p. 399 - 405

Long-term disturbance of the calcium homeostasis of motor endplates (MEPs) causes necrosis of muscle fibers. The onset of morphological changes in response to this disturbance, particularly in relation to the fiber type, is presently unknown. Omohyoid muscles of mice were incubated for 1-30 minutes in 0.1 mM carbachol, an acetylcholine agonist that causes an inward calcium current. In these...

The direct effect of leptin on skeletal muscle thermogenesis is mediated by substrate cycling between de novo lipogenesis and lipid oxidation

Solinas, Giovanni ; Summermatter, Serge ; Mainieri, Davide ; Gubler, Marcel ; Pirola, Luciano ; Wymann, Matthias P. ; Rusconi, Sandro ; Montani, Jean-Pierre ; Seydoux, Josiane

In: FEBS Letters, 2004, vol. 577, no. 3, p. 539-544

We report here studies that integrate data of respiration rate from mouse skeletal muscle in response to leptin and pharmacological interference with intermediary metabolism, together with assays for phosphatidylinositol 3-kinase (PI3K) and AMP- activated protein kinase (AMPK). Our results suggest that the direct effect of leptin in stimulating thermogenesis in skeletal muscle is mediated by...
