Promyelocytic leukemia zinc finger (PLZF) protein is a sequence-specific DNA-binding protein that represses the transcriptional activity of target genes such as those for cyclin A and the interleukin-3 receptor alpha chain. The PLZF gene becomes fused to the retinoic acid receptor alpha gene as a result of the t(11, 17)(q23;q21) chromosomal translocation that is associated with acute promyelocy...

Monocyte differentiation induced by 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) is interrupted during the course of acute promyelocytic leukemia (APL). One form of APL is associated with the translocation t(11;17), which joins the promyelocytic leukemia zinc finger (PLZF) and retinoic acid receptor alpha (RARalpha) genes. Because PLZF is coexpressed in the myeloid lineage with the vitamin D(3)...

The transcription factor PLZF [promyelocytic leukemia zinc finger, encoded by zinc finger BTB domain containing 16 (Zbtb16)] is induced during the development of innate and innate-like lymphocytes to direct their acquisition of a T-helper effector program, but the molecular mechanisms involved are poorly understood. Using biotinylation-based ChIP-seq and microarray analysis of both natural kill...

Promyelocyte Leukemia Zinc Finger (PLZF) is a Kruppel-like zinc finger gene previously identified in a unique case of acute promyelocytic leukemia (APL) as the counterpart of a reciprocal chromosomal translocation involving the retinoic acid receptor alpha gene (RAR alpha). PLZF is highly conserved throughout evolution from yeast to mammals. To elucidate its role, we isolated the murine PLZF ge...

Promyelocytic leukemia zinc finger (PLZF) protein expression is closely related to the progression of human cancers, including prostate cancer (PCa). However, the according context of a signaling pathway for PLZF to suppress prostate tumorigenesis remains greatly unknown. Here we report that PLZF is a downstream mediator of the PTEN signaling pathway in PCa. We found that PLZF expression is clo...

Promyelocytic leukemia zinc finger protein (PLZF) is a protein involved in various signaling, growth regulatory, and differentiation pathways, including development/function of some T cells. Here, we aimed at the detection of PLZF during colorectal carcinogenesis, using immunofluorescence, and at the evaluation of the colocalization of PLZF with CD2 and CD56 positive cells (T, γ δ , NK, and NKT...

BACKGROUND: Retinoic acid receptors (RARs) are ligand-regulated transcription factors controlling cellular proliferation and differentiation. Receptor-interacting proteins such as corepressors and coactivators play a crucial role in specifying the overall transcriptional activity of the receptor in response to ligand treatment. Little is known however on how receptor activity is controlled by i...

The promyelocytic leukaemia zinc finger (PLZF) protein belongs to the family of Krüppel-like zinc finger proteins. It is a transcriptional repressor involved in cell cycle control and has been implicated in limb development, differentiation of myeloid cells, and spermatogenesis. Little is known about the regulation of PLZF expression. In search for mediators of progesterone signalling in the fe...

Ectopic repression of retinoic acid (RA) receptor target genes by PML/RARA and PLZF/RARA fusion proteins through aberrant recruitment of nuclear corepressor complexes drives cellular transformation and acute promyelocytic leukemia (APL) development. In the case of PML/RARA, this repression can be reversed through treatment with all-trans RA (ATRA), leading to leukemic remission. However, PLZF/R...

BACKGROUND Pressure overload and prolonged angiotensin II (Ang II) infusion elicit cardiac hypertrophy in Ang II receptor 1 (AT(1)) null mouse, whereas Ang II receptor 2 (AT(2)) gene deletion abolishes the hypertrophic response. The roles and signals of the cardiac AT(2) receptor still remain unsettled. Promyelocytic leukemia zinc finger protein (PLZF) was shown to bind to the AT(2) receptor an...
