Target Background

Transcriptional activator that binds to DNA sequences containing the consensus pentanucleotide 5'-CGGA[AT]-3'.
Gene References into Functions
  1. Our data indicate that miR-17-5p acts as a tumour suppressor in Triple-negative breast cancer (TNBC)by targeting ETV1, and a low-abundance of miR-17-5p may be involved in the pathogenesis of TNBC. These findings indicate that miR-17-5p may be a therapeutic target for TNBC PMID: 29126392
  2. Our results indicate that assessing AP1 and PEA3 transcription factor status might be a good indicator of OAC status. However, we could not detect any associations with disease stage or patient treatment regime. This suggests that the PEA3-AP1 regulatory module more likely contributes more generally to the cancer phenotype. In keeping with this observation, depletion of ETV1 and/or ETV4 causes an OAC cell growth defect PMID: 28859074
  3. Structured and disordered regions cooperatively mediate DNA-binding autoinhibition of ETV1, ETV4 and ETV5. PMID: 28161714
  4. the prostate cancer-related oncogenic E26 transformation-specific (ETS) transcription factors, ETV1, ETV4, and ETV5, were required for TAZ gene transcription in PC3 prostate cancer cells PMID: 28408625
  5. C646 treatment attenuated ETV1 protein expression and inactivated KIT-dependent pathways. Taken together, the present study suggests that CBP/p300 may serve as novel antineoplastic targets and that use of the selective HAT inhibitor C646 is a promising antitumor strategy for Gastrointestinal stromal tumors. PMID: 27633918
  6. these data reveal a JMJD2A/ETV1/YAP1 axis that promotes prostate cancer initiation and that may be a suitable target for therapeutic inhibition. PMID: 26731476

  8. ETV1 and COP1 are a pair of independent predictors of prognosis for triple-negative breast cancer. PMID: 25884720
  9. ETV1 overexpression is associated with prostate cancer aggressiveness. PMID: 25595908
  10. Results show that ETV1 was upregulated at a higher rate in Gastrointestinal stromal tumor and was correlated with KIT expression. PMID: 24970355
  11. These results illuminate the complex interplay of AR, ETV1, and PTEN pathways in pre-cancerous neoplasia and early tumorigenesis PMID: 25631336
  12. YK-4-279 is a potent inhibitor of ETV1 and inhibits both the primary tumor growth and metastasis of fusion positive prostate cancer xenografts. PMID: 25479232
  13. mutation of the KIT protein that stabilizes ETV1 is likely to be a key step by which an endogenous brain-cell progenitor may form a germinoma. PMID: 25736805
  14. ETV1 expression is a rare event in human melanoma and seems to be rather based on hyperactivation of MAPK signals, by BRAF (V600E) mutation, than on ETV1 gene amplification. PMID: 25073704
  15. developed a novel RNA in situ hybridization-based assay for the in situ detection of ETV1, ETV4, and ETV5 in formalin-fixed paraffin-embedded tissues from prostate needle biopsies, prostatectomy, and metastatic PCa specimens using RNA probes PMID: 25203299
  16. Elevated levels of either wild-type ETV1 or its truncated derivative, dETV1, which mimics the product of an oncogenic rearrangement in certain tumors, results in increased expression of mRNA for p14ARF, a known activator of p53. PMID: 24157551
  17. These results point to a new avenue for pharmacologic ETV1 inhibition and may inform a general means to discover small molecule perturbagens of transcription factor oncoproteins. PMID: 24737027
  18. The gastrointestinal stromal tumor-specific transcription factor ETV1 may have no prognostic potential, whereas its downstream gene KCTD10 is associated with a favorable prognosis. PMID: 23977394
  19. ETV1 expression is significantly correlated with Snail expression in human gastric tumor samples. In summary, we present data that ETV1 promotes Snail expression to induce EMT-like metastatic progression in gastric cancer. PMID: 24100634

  30. High ER81 expression is associated with gastric adenocarcinoma. PMID: 21673681
  31. in clinical prostate cancer overexpression of full-length ETV1 is due to genomic rearrangements involving different chromosomes PMID: 21298110
