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 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 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 کاملInduction of triploidy in the mouse by cytochalasin B.
Mouse eggs fertilized in vivo were treated with cytochalasin B in vitro (5 mug/ml of culture medium) at the moment of extrusion of the second polar body (2-5, 3-0, 3-5 h after copulation). Cytochalasin B inhibits cytokinesis of the second maturation division, so that triploid digynic eggs are formed in over 50% of treated eggs. Triploid eggs were transplanted to the oviducts of recipients. On t...
