In contrast to most Staphylococcus aureus isolates in which the gene for staphylococcal beta-lactamase (blaZ) is plasmid borne, isolates typeable by group II bacteriophages frequently carry blaZ on the chromosome. Furthermore, the chromosomal gene encodes the type B variant of staphylococcal beta-lactamase for which the nucleotide and deduced amino acid sequences have not yet been reported. To ...
PURPOSE To understand the involvement of isoprenylated small guanosine triphosphatases (GTPases) in lovastatin-induced cataractogenesis, Rho- and Rac-mediated cell adhesion and actin cytoskeletal reorganization were investigated in lovastatin-treated lens epithelial cells. METHODS The effects of lovastatin on F-actin reorganization (phalloidin staining), focal adhesion formation (paxillin or ...
To study an endocytotic role of the GTP-binding protein RhoA in Xenopus oocytes, we have monitored changes in the surface expression of sodium pumps, the surface area of the oocyte and the uptake of the fluid-phase marker inulin. Xenopus oocytes possess intracellular sodium pumps that are continuously exchanged for surface sodium pumps by constitutive endo- and exocytosis. Injection of Clostrid...
Signalling via m3 and m2 receptors in smooth muscles involved activation of two G-protein-dependent pathways by each receptor. m2 receptors were coupled via Gbetagammai3 with activation of phospholipase C-beta3, phosphoinositide 3-kinase and Cdc42/Rac1 (where Cdc stands for cell division cycle) and p21-activated kinase 1 (PAK1), resulting in phosphorylation and inactivation of myosin light chai...
