Gene References into Functions
  1. HSP27 is a partner of JAK2-STAT5 and a potential therapeutic target in myelofibrosis. PMID: 29650953
  2. the two cell lines exhibited relatively low protein expression levels of p53, lower levels of p53 and TPp53BP1 transcripts were detected in the K562/G cells. Taken together, these findings suggest that the resistance of CML to the tyrosine kinase inhibitor, imatinib, may be associated with persistent STAT5-mediated ROS production, and the abnormality of the p53 pathway PMID: 29115375
  3. Peripheral blood Tregs failed to effectively utilize IL-2 and had relatively little STAT5 phosphorylation in active ankylosing spondylitis. PMID: 27901054
  4. These results indicate that IL-3 regulates endothelial cells-extracellular vesicles release, cargo and IL-3 angiogenic paracrine action via STAT5. PMID: 27157262
  5. Similar to normal developmental programs, oncogenic functions of STAT5 rely on molecular crosstalk with PI3K/AKT signaling for the initiation, and in some instances the progression, of breast cancer. (Review) PMID: 28495456
  6. we demonstrated that Imatinib mesylate (IM)impaired T cell survival through the inhibition of IL-7 and STAT5-p but not TCR signaling which remained unaffected during IM therapy. Thus, off-target inhibitory effects of IM on IL-7 and STAT5-p explain how T cell lymphopenia occurs in patients treated with IM. PMID: 28387753
  7. Our results suggest the regulation of STAT5A via epigenetic mechanisms during normal pregnancy and the association of STAT5A epigenetic dysregulation in pregnancy related complications PMID: 27452437

  9. STAT3/miR-211/STAT5A signaling plays a key role in mesenchymal stem cell migration. PMID: 27145179

  13. O-GlcNAcylation and tyrosine phosphorylation act together to trigger pYSTAT5 levels and oncogenic transcription in neoplastic cells. A mutated hyperactive gain-of-function (GOF) STAT5 without O-GlcNAcylation resulted in decreased tyrosine phosphorylation, oligomerization and transactivation potential and complete loss of oncogenic transformation capacity. PMID: 28074064
  14. STAT5 interacted with minichromosome maintenance (MCM) complex, suggesting that STAT5 directly facilitates viral DNA replication by recruiting the helicase complex of the cellular DNA replication machinery to viral DNA replication centers. PMID: 28459842
  15. High STAT5 phosphorylation is associated with systemic lupus erythematosus. PMID: 28254841
  16. NPM1 downregulation by P-STAT5 is mediated by impairing the BRCA1-BARD1 ubiquitin ligase, which controls the stability of NPM1. In turn, decreased NPM1 levels led to suppression of p53 expression, resulting in enhanced cell survival. PMID: 28005077
  17. High STAT5A expression is associated with B-lymphoblastic lymphoma with inflammation. PMID: 27018255
  18. Results provide evidence that HDAC6 could regulate HMGN2 acetylation levels and binding to Stat5a-responsive promoters, and therefore, Stat5a transcriptional activity in breast cancer cells. PMID: 27358110
