TranscriptomicsGenome-Wide STAT5 binding sites in Kit225 leukemia cells
In order to systematically map STAT5 genomic binding sites and IL-2 mediated gene expression changes we mapped STAT5 binding sites using chip-on-ChIP in IL-2 dependent Kit225 cells that were either left un-stimulated or stimulated with IL-2 for 30 minutes. Using MAT analysis we identified 1581 STAT5...

GenomicsDynamic, sex-differential STAT5 and BCL6 binding to sex-biased, growth hormone-regulated genes in adult mouse liver
Sex-dependent pituitary growth hormone (GH) secretory patterns determine the sex-biased expression of >1,000 genes in mouse and rat liver, affecting lipid and drug metabolism, inflammation and disease. A fundamental biological question is how robust differential expression can be achieved for hundre...

GenomicsGenome-wide analyses reveal the extent of opportunistic STAT5 binding that does not yield transcriptional activation of neighboring genes.
Signal Transducers and Activators of Transcription (STAT) 5A/B regulate cytokine-inducible genes upon binding to GAS motifs. It is not known what percentage of genes with GAS motifs bind to and are regulated by STAT5. Moreover, it is not clear whether genome-wide STAT5 binding is modulated by its co...

TranscriptomicsCritical Role of STAT5 Transcription Factor Tetramerization for Cytokine Responses and Normal Immune Function (RNA)
Cytokine-activated STAT proteins dimerize and bind to high-affinity motifs, and N-terminal domain-mediated oligomerization of dimers allows tetramer formation and binding to low-affinity tandem motifs, but the functions of dimers versus tetramers are unknown. We generated Stat5a and Stat5b double kn...

GenomicsActive STAT5 in CD8 T cells imprints a T-Bet-dependent Tc-1 program with repressed IL-6/ TGFb1 signaling leading to enhanced anti-tumor responses
CD8 T cells (TCs) expressing active STAT5 (STAT5CA) transcription factors were found to be superior to un-manipulated counterparts in their long-term persistence, capacity to infiltrate a tumor, thrive in its microenvironment and induce its regression. STAT5CA induced sustained expression of genes c...

GenomicsSTAT5 paralog dose governs T cell effector and regulatory function
The transcription factor STAT5 is fundamental to the mammalian immune system. However, the relationship between its two paralogs, STAT5A and STAT5B, and the extent to which they are functionally distinct, remains controversial. We addressed this longstanding question in primary CD4+ 'helper' T cells...

GenomicsImpact of STAT5 dosage and binding location on genetic and biological programs activated in mouse mammary epithelium during pregnancy.
The transcription factor STAT5 has long been recognized as an important mediator of prolactin induced mammary development during pregnancy. We have used mouse genetics and genome-wide analyses to determine how altering concentrations of STAT5A and STAT5B impacts different target promoters. Examinati...

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...

TranscriptomicssiRNA profiling of mouse samples knocked doen for Stat5 to identify its target genes
STAT5A and STAT5B proteins belong to the family of signal transducers and activators of transcription. They are encoded by 2 separate genes with 91% identity in their amino acid sequences. Despite their high degree of conservation, STAT5A and STAT5B exert non-redundant functions, resulting at least ...

TranscriptomicsRoles of STAT3 and STAT5 in regulation of gene expression under Th17 differentiation
Interleukin 2 (IL-2), a cytokine linked to human autoimmune diseases, limits IL-17 production. We show that deletion of Stat3 in T cells abrogates IL-17 production and attenuates autoimmunity associated with IL-2 deficiency. While STAT3 induces IL-17 and ROR?t and inhibits Foxp3, IL-2 inhibited IL-1...
