Abstract

Background: Promyelocytic leukemia zinc finger-retinoic acid receptor - (PLZF-RAR-) is a transcriptional repressor generated by a chromosomal translocation between the PLZF and RAR- genes in acute promyelocyteic leukemia patients. Results: The transcriptional regulation ofCDKN1Aby PLZF-RAR- involves the competitive binding of p53,RAR-, and Sp1, the modification of histones, and DNA methylation at the promoter. Conclusion: PLZF-RAR- increases cell proliferation by repressing p21 expression. Significance: Oncoprotein PLZF-RAR- represses transcription of the CDKN1A.
