The mold metabolite cytochalasin B blocked transmission through the perfused superior cervical sympathetic ganglion of the cat. Acetylcholine injected close-arterially during block continued to excite the ganglion cells so that failure was presynaptic and, by inference, due to reduced output of acetylcholine from the preganglionic nerves. This blocking effect of cytochalasin was reduced by pyru...
Movement of extrusomes in the heliozoon Actinophrys sol was characterized at surfaces of the cell body and giant food vacuoles where microtubules are absent. Extrusomes moved in a saltatory manner at an average velocity of 0.5 μms-1. The highest velocity observed was 2.1 μms-1. Cytochalasin B (50 μg/ml) strongly inhibited extrusome movement at the surfaces of newly-formed food vacuoles, suggest...
Human tumor cell lines derived from melanoma, glioblastoma, and carcinoma of the prostate, bladder, and kidney multinucleated in response to growth in cytochalasin B-supplemented medium, whereas cell lines derived from normal prostate, kidney, skin, lung, and other nonmalignant diseases remained predominantly binucleate under comparable conditions. The multinucleate cytochalasin B phenotype was...
Numerous reports have linked cytoskeleton-associated proteins with the regulation of epithelial Na(+) channel (ENaC) activity. The purpose of the present study was to determine the effect of actin cytoskeleton disruption by cytochalasin E on ENaC activity in Xenopus 2F3 cells. Here, we show that cytochalasin E treatment for 60 min can disrupt the integrity of the actin cytoskeleton in cultured ...
