Abstract

The PU.1 gene encodes an Ets family transcription factor which controls expression of many B cell- and macrophage-specific genes. Expression of the gene is critical for development of lymphoid and myeloid cell lineages, since PU.1-deficient mice exhibit defects in the development of these cell lineages. The PU.1 gene is identical to the Spi-1 gene isolated from common proviral integration sites in Friend virus-induced murine erythroleukemia (MEL), and deregulated expression of the gene is believed to be an essential step of the disease. We recently demonstrated that overexpression of PU.1 inhibits erythroid differentiation of MEL cells induced with the differentiating agent DMSO. We also noticed unexpectedly that overexpression of PU.1 together with DMSO induces marked growth arrest and apoptosis in MEL cells, supporting the notion that some oncogenes induce growth inhibition and apoptosis rather than cell proliferation and transformation under specific circumstances as shown with the c-myc gene. In this review, the role of PU.1 in hematopoietic cell differentiation, proliferation and apoptosis is described and the possible molecular mechanisms of PU.1-induced effects in MEL cells are discussed.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Borzoi correctly predicts upregulation of SHTN1 expression owing to the creation of a CEBP binding motif.

    “Borzoi correctly predicts the upregulation of SHTN1 expression owing to the creation of a CEBP binding motif69–72 (see Supplementary Fig. 9a and Extended Data Fig. 6a,b for additional examples).”
  • PU.1 is commonly characterized as a lineage differentiation factor, and its role as a regulator of cell proliferation has also been extensively studied.

    “while PU.1 is commonly characterized as a lineage differentiation factor, its role as a regulator of cell proliferation has also been extensively studied (Delestré et al., 2017; Fukuchi et al., 2008; Oikawa et al., 1999; Solomon et al., 2017; Ziliotto et al., 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
