靶點詳情

  • 功能:
    Endothelins are endothelium-derived vasoconstrictor peptides.
  • 基因功能參考文獻:
    1. EDN2 expression in left internal mammary arteries depends on tissue harvesting technique. PMID: 24647318
    2. Overexpression of Edn2 in the mouse retina causes an excess of tip cells and inhibits vascular growth. Overexpression of Edn2 in the brain and skin had no effect, but vascular development was inhibited in midgestation mouse embryos. PMID: 24043815
    3. Endothelin 2 and endothelin receptor type B may be a regenerative pathway for central nervous system myelination and remyelination. PMID: 23518706
    4. Studies revealed hypermethylation of EDN2 and EDN3 genes in human primary colon cancers and in a panel of human colon cancer cell lines. Epigenetic inactivation of ET-2 and ET-3 occurs frequently in both rat and human colon cancers. PMID: 22865632
    5. plasma levels of big ET-2, and big ET-3 are markedly increased in patients with end stage renal disease on hemodialysis PMID: 22921304
    6. In granulosa lutein cells from women with polycystic ovary syndrome, endothelin-2 mRNA was reduced as compared with normally ovulating women PMID: 22727793
    7. although endothelin 2 does not appear to be an independent prognostic marker, there is evidence of a putative role in clear cell renal cell carcinoma progression PMID: 22047647
    8. Endothelin-2 is a macrophage chemoattractant. ET-2 expression by tumors may modulate the behavior of macrophages such that activated cells accumulate in areas of hypoxia. PMID: 12207323
    9. Endothelin-2 is a hypoxia-induced autocrine survival factor for breast tumor cells PMID: 12516960
    10. The EDN2 A985 allele, which is considered to be protective in cardiovascular disease, may be a risk factor for atrial fibrillation in patients with hypertrophic cardiomyopathy. PMID: 18037749
