title: [Study of dominant negative effect of the PLZF-RARalpha against the wild-type RARalpha in acute promyelocytic leukemia].
abstract: OBJECTIVE
  To explore the role of promyelocytic leukemia zinc finger (PLZF) gene on 11q23 and RARalpha gene on 17q21.
  
  
  METHODS
  Eight PLZF/RARalpha expression plasmids with deletions of different PLZF motifs were constructed by using PCR based-method.
  
  
  CONCLUSIONS
  By transient co-transfection, it was confirmed that PLZF/RARalpha had a dominant negative effect against the wild-type RARalpha, the POZ domain of PLZF/RARalpha was responsible for the dominant negative effect and the PLZF/RARalpha may play certain role through a spatial interaction with POZ.
