TranscriptomicsThe transcription factors STAT5a/b negatively regulate cell proliferation through the activation of cdkn2b and cdkn1a expression
Although the cytokine-inducible transcription factors STAT5a/b promote proliferation of a wide range of cell types, there are cell- and context specific cases in which loss of STAT5a/b results in enhanced cell proliferation. Here we report that loss of STAT5a/b from mouse embryonic fibroblasts (MEFs...

TranscriptomicsDistinct STAT5 concentrations uniquely control establishment and differentiation of mammary epithelium during pregnancy
To dissect regulatory processes of cell proliferation and differentiation we generated mouse strains carrying any combination of the four Stat5 alleles, thus expressing STAT5 from 0 to 100%. RNA-Seq analyses revealed that different STAT5 levels activate specific genetic programs linked to cell proli...

TranscriptomicsDevelopment of mammary luminal progenitor cells is controlled by the transcription factor STAT5A
Mammary alveologenesis is abrogated in the absence of the transcription factors STAT5A/5B that mediate cytokine signaling. To reveal the underlying causes for this developmental block we studied mammary stem and progenitor cells. While loss of STAT5A/5B did not affect the stem cell population and ...

TranscriptomicsThe gene encoding the hematopoietic stem cell regulator CCN3 (NOV) is under direct cytokine control through the transcription factors STAT5a/b.
Cytokines control the biology of hematopoietic stem and progenitor cells in part through the transcription factors STAT5a/b. CCN3/NOV has been reported as a positive regulator of hematopoietic stem and progenitor cells. We report microarray analyses of Lineage- Sca-1+ c-Kit+ (KSL) cells in the pre...
