Cytochalasin B and the Adenosine Triphosphate Content of Treated Fibroblasts
INTRODUCTION the addition of the drug . Concentrations of about 3 μg/ml were required to observe altered cell morphology. The possibility was considered that depolymerization of microfilaments-with a resulting change in cell shape and function--resulted from a rapid depletion of intracellular energy levels brought about by the inhibition of sugar transport . The effects of cytochalasin B and io...
متن کاملDifferences in malsegregation rates obtained by scoring ana-telophases or binucleate cells.
In this work we have applied in situ hybridization with alphoid centromeric probes specific to chromosomes 7 and 11 to ana-telophase cells from human primary fibroblasts. The aim was to visualize the events leading to aneuploidy directly during anaphase, analyse the induction of aneuploidy during this mitotic stage and compare the frequencies of chromosome malsegregation observed in ana-telopha...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Cytochalasin B inhibits the proliferation of human glioma U251 cells through cell cycle arrest and apoptosis.
Cytochalasin B (CB) is known to inhibit a number of cancer types, but its effects on gliomas are unknown. We examined the in vitro effects of CB on the proliferation of human glioma U251 cells, as well as determined its mechanism of action. Cell proliferation was determined using CCK-8. The effect of CB on U251 cell morphology was observed under a transmission electron microscope. Cell cycle di...
متن کاملCytochalasin 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...
