Colchicine, colcemide and cytochalasin B do not affect translocation of the glucocorticoid hormone-receptor in rat thymocytes or Ehrlich ascites cells.

The involvement of intracellular cytoskeletal elements in the translocation of the dexamethasone-receptor complex from the cytoplasm to the nucleus was studied using the cytoskeleton-disrupting agents colcemide, colchicine and cytochalasin B. These compounds did not affect the translocation of the hormone-receptor complex. We conclude that microfilaments and microtubules do not play a role in the translocation of the glucocorticoid hormone-receptor complex from the cytoplasm to the nucleus.
