Cytochalasin B
Cytochalasin B competitively inhibits the transport of uridine and thymidine by Novikoff rat hepatoma cells growing in suspension culture with apparent K(i)'s of 2 and 6 microM, respectively, but has no effect on the intracellular phosphorylation of the nucleosides. Choline transport is not affected by cytochalasin B. Results from pulse-chase experiments indicate that cytochalasin B has no dire...
متن کاملCytochalasin B
Cytochalasin B, a mold metabolite, has been shown to inhibit cytokinesis and motility (3), morphogenie development (18), endocytosis (5), and the transport of sugars (8-10, 12). I t has also been demonstrated that this drug inhibits the stimuatcd elaboration of extracellular substances from glands-the release of thyroxine from the thyroid gland after stimulation by thyroid-stimulating hormone (...
متن کاملCytochalasin B and Pigment Granule Translocation
The redistribution of melanin granules within dermal and epidermal melanocytes of the frog is responsible for changes in skin color . Surviving frog skin can be lightened and darkened by many different compounds (I). When the granules are dispersed into the branched processes of individual melanocytes, the skin appears dark . When melanin granules are aggregated in the perikaryon, the melanocyt...
متن کاملCytochalasin B Modulates Macrophage-Mediated Inflammatory Responses
The actin cytoskeleton plays an important role in macrophage-mediated inflammatory responses by modulating the activation of Src and subsequently inducing nuclear factor (NF)-κB translocation. In spite of its critical functions, few papers have examined how the actin cytoskeleton can be regulated by the activation of toll-like receptor (TLR). Therefore, in this study, we further characterized t...
متن کاملCytochalasin B and embryonic heart muscle: contractility, excitability and ultrastructure.
The effect of cytochalasin B (CB) on beating, electrical activity and cytological ultrastructure of embryonic hearts and tissue-cultured heart preparations was investigated. The inhibition of spontaneous pulsation and the subsequent recovery after drug washout were found to be dosedependent and to be a function of the type of preparation. In the presence of CB, spontaneous action potentials can...
