Nuclear expression of hypoxia-inducible factor 1alpha protein is heterogeneous in human malignant cells under normoxic conditions.

abstract：:The expression of DNA-topoisomerase II was analysed at the protein level in newly diagnosed cases of acute lymphoblastic leukemia (ALL) in children. Blast cells obtained from 81 children with untreated ALL were determined by means of immunocytochemistry. Of the ALL, 49 (60%) were positive for topoisomerase II and 32 (...
