SFFV proviral integration 1

PU.1, Spi-1
This gene encodes an ETS-domain transcription factor that activates gene expression during myeloid and B-lymphoid cell development. The nuclear protein binds to a purine-rich sequence known as the PU-box found near the promoters of target genes, and regulates their expression in coordination with other transcription factors and cofactors. The protein can also regulate alternative splicing of target genes. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008] (from NCBI)

PU.1-Silenced Dendritic Cells Induce Mixed Chimerism and Alleviate Intestinal Transplant Rejection in Rats via a Th1 to Th2 Shift.
New
Li et al., Nanjing, China. In Cell Physiol Biochem, Feb 2016
Here, we demonstrate that in rat intestinal transplantation, PU.1-silenced dendritic cells (DCs) plus bone marrow (BM) cell transfusion results in mixed chimerism, and we investigate the mechanisms responsible for the effects of mixed chimerism rejection.

Ebrahimi et al., Tehrān, Iran. In Ann Hematol, Feb 2016
To demonstrate whether PU.1 suppression induces monocyte lineage conversion into red blood cells, a combination of three PU.1-specific siRNAs was implemented to knock down PU.1 gene expression and generate the balance in favor of GATA-1 expression to induce erythroid differentiation.

New
Schultze et al., Bonn, Germany. In Cell Res, Feb 2016
UNASSIGNED: Differentiation of inflammatory macrophages from monocytes is characterized by an orderly integration of epigenetic and transcriptional regulatory mechanisms guided by lineage-determining transcription factors such as PU.1.

Early enhancer establishment and regulatory locus complexity shape transcriptional programs in hematopoietic differentiation.
New
Impact
Leslie et al., New York City, United States. In Nat Genet, Nov 2015
Our method suggests a new mechanistic role for PU.1 at transition peaks during B cell specification and can be used to correct assignments of enhancers to genes.
Minimal PU.1 reduction induces a preleukemic state and promotes development of acute myeloid leukemia.
New
Impact
Steidl et al., United States. In Nat Med, Oct 2015
Although loss or near-complete loss of the hematopoietic transcription factor PU.1 induces acute myeloid leukemia (AML) in mice, a similar degree of PU.1 impairment is exceedingly rare in human AML; yet, moderate PU.1 inhibition is common in AML patients.
Population Variation and Genetic Control of Modular Chromatin Architecture in Humans.
New
Impact
Dermitzakis et al., Lausanne, Switzerland. In Cell, Sep 2015
Chromatin state variation at gene regulatory elements is abundant across individuals, yet we understand little about the genetic basis of this variability.
RORC1 Regulates Tumor-Promoting "Emergency" Granulo-Monocytopoiesis.
New
Impact
Sica et al., Milano, Italy. In Cancer Cell, Sep 2015
RORC1 orchestrates myelopoiesis by suppressing negative (Socs3 and Bcl3) and promoting positive (C/EBPβ) regulators of granulopoiesis, as well as the key transcriptional mediators of myeloid progenitor commitment and differentiation to the monocytic/macrophage lineage (IRF8 and PU.1).

Review
New
Ponting et al., Oxford, United Kingdom. In Neurobiol Aging, Aug 2015
We identified a subnetwork of transcription factors, including RUNX1, IRF8, PU.1, and TAL1, which are master regulators (MRs) for the age-dependent microglia module.
Positive and negative regulators of the metallothionein gene (review).
Review
New
Takahashi, Sagamihara, Japan. In Mol Med Report, Jul 2015
Previous studies from the group of the present review have revealed that the hematopoietic master transcription factor, PU.1, directly represses the expression levels of MT genes through its epigenetic activities, and upregulation of MT results in the potent inhibition of myeloid differentiation.
Batf3 maintains autoactivation of Irf8 for commitment of a CD8α(+) conventional DC clonogenic progenitor.
New
Impact
Murphy et al., Saint Louis, United States. In Nat Immunol, Jul 2015
Irf8 expression in CDPs required prior autoactivation of Irf8 that was dependent on the transcription factor PU.1.

Review
New
Badie et al., Melbourne, Australia. In Carcinogenesis, Apr 2015
The transcription factor PU.1, encoded by the murine Sfpi1 gene (SPI1 in humans), is a member of the Ets transcription factor family and plays a vital role in commitment and maturation of the myeloid and lymphoid lineages.

Runx1 is induced by high Pu.1 level and in turn transrepresses pu.1 expression, thus constituting a negative feedback loop that fashions a favorable Pu.1 level required for balanced fate commitment to neutrophils versus macrophages.
