Transcription factor PU.1 and immune cell differentiation (Review)
PU.1 expression is increased during granulocyte and macrophage differentiation, while it is decreased during T lymphocyte and B lymphocyte differentiation. The present study reviews and discusses the effects of the transcription factor PU.1 on immune cell differentiation.
Distinctive and indispensable roles of PU.1 in maintenance of ...
2005年9月1日 · By using a conditional PU.1 knock-out model, we here show that HSCs express PU.1, and its constitutive expression is necessary for maintenance of the HSC pool in the bone marrow. Bone marrow HSCs disrupted with PU.1 in situ could not maintain hematopoiesis and were outcompeted by normal HSCs.
The transcription factor PU.1 is a critical regulator of cellular ...
PU.1 is an E26 transformation-specific family transcription factor that is required for development of the immune system. PU.1 functions at both early and late stages of lymphoid and myeloid differentiation. At least 110 direct target genes of PU.1 have …
The role of a key transcription factor PU.1 in autoimmune diseases
PU.1, a transcription factor member of the E26 transformation-specific family, affects the function of a variety of immune cells in several physiological and pathological conditions.
Transcription Factor PU.1 Promotes Conventional Dendritic Cell …
2019年1月15日 · We found that conditional ablation of the Ets-family transcription factor PU.1 in DC-restricted progenitors led to increased pDC production at the expense of cDCs. PU.1 controlled many of the cardinal functions of DCs, such as antigen presentation by cDCs and type I interferon production by pDCs.
PU.1 and partners: regulation of haematopoietic stem cell fate in ...
The haematopoietic-specific Ets family transcription factor PU.1 regulates many lymphoid- and myeloid-specific gene promoters and enhancers by interacting with multiple proteins during haematopoietic development.
The key role of PU.1/SPI-1 in B cells, myeloid cells and macrophages
1999年4月1日 · PU.1 is a member of the transcription factor family Ets that is expressed selectively on B cells, myeloid cells and macrophages. PU.1 regulates the expression of several genes, including those encoding immunoglobulins, receptors and enzymes.
Mechanisms governing the pioneering and redistribution
2020年1月21日 · Establishing gene regulatory networks during differentiation or reprogramming requires master or pioneer transcription factors (TFs) such as PU.1, a prototype master TF of hematopoietic lineage...
PU.1-c-Jun interaction is crucial for PU.1 function in myeloid ...
2022年9月14日 · PU.1 controls hematopoietic differentiation through physical interactions with other transcription factors, such as C/EBPα and the AP-1 family member c-Jun. We found that PU.1 recruits c-Jun...
PU.1: A crucial and versatile player in hematopoiesis and leukemia
2008年1月1日 · PU.1 is expressed strongly in early hematopoietic cells including hematopoietic stem cells (HSCs), common lymphoid progenitors (CLPs), granulocyte/macrophage progenitors (GMPs) and early thymic progenitors (ETPs).
