The light chain but not the heavy chain of botulinum A toxin inhibits exocytosis from permeabilized adrenal chromaffin cells.
The heavy and light chains of botulinum A toxin were separated by anion exchange chromatography. Their intracellular actions were studied using bovine adrenal chromaffin cells permeabilized with streptolysin O. Purified light chain inhibited the Ca2+-stimulated [3H]noradrenaline release with a half-maximal effect at about 1.8 nM. The inhibition was incomplete. Heavy chain up to 28 nM was neithe...
متن کاملEffects of relaxin on rat uterine myosin light chain kinase activity and myosin light chain phosphorylation.
Isometrically suspended uteri from estrogen-primed rats were stimulated with prostaglandin F2 alpha and then exposed to relaxin. Relaxin-dependent decreases in the ratio of phosphorylated to total myosin light chains (MLC) and in MLC kinase activity, measured in the presence of 0.5 mg/ml of uterine myosin and the absence and presence of Ca2+-calmodulin (CaM), were observed. The time-course and ...
متن کاملL-Arginine Supplementation Influenced Nitrite but Not Nitrate and Total Nitrite in Rabbit Model of Hypercholesterolemia
Background: The assessment of altered nitric oxide (NO) availability is of potentially important diagnostic and prognostic significance. The present study is aimed to investigate the effect of L-arginine (as a natural NO donor) supplementation on NO metabolite in a rabbit model of hypercholesterolemia to find a reliable marker for endothelial NO production. Methods: White male rabbits (n = 30)...
متن کاملMechanical activity in heart regulates translation of α-myosin heavy chain mRNA but not its localization.
Mechanical inactivity depresses protein expression in cardiac muscle tissue and results in atrophy. We explore the mechanical transduction mechanism in spontaneously beating neonatal rat cardiomyocytes expressing the α-myosin heavy chain (α-MyHC) isoform by interfering with cross-bridge function [2,3-butanedione monoxime (BDM), 7.5 mM] without affecting cell calcium. The polysome content and α-...
متن کاملKinesin light chain-independent function of the Kinesin heavy chain
In Drosophila, the asymmetries that specify the embryonic axes are established early during oogenesis in a process that requires the precise localisation of several transcripts (Riechmann and Ephrussi, 2001; van Eeden and St Johnston, 1999). The localisation of oskar mRNA to the posterior pole of the oocyte specifies where the pole plasm forms, and thus where the abdomen and the germ line will ...
