產品詳情

  • 產品描述：
    人尿皮素-2(UCN2)酶聯免疫試劑盒（CSB-EL025552HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、組織培養上清液樣本中的UCN2含量。UCN2 是一個靶點。UCN2 即尿皮質素 2，屬促腎上腺皮質激素釋放因子家族，參與調節應激反應、心血管功能及能量代謝。研究機制上，其通過與特定受體結合激活下游信號通路，為相關疾病如心血管病、代謝病的治療帶來新方向。試劑盒檢測范圍為6.25 pg/mL-400 pg/mL，該產品適用于體外研究場景，如探究UCN2在代謝調控相關細胞模型中的分泌動態、動物實驗中的組織分布分析，或臨床前研究中的生物標志物探索，為心血管疾病、肥胖癥及應激相關分子機制研究提供可靠工具。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    Suppresses food intake, delays gastric emptying and decreases heat-induced edema. Might represent an endogenous ligand for maintaining homeostasis after stress.

    3. Data show that corticotropin releasing hormone receptor 2 (Crhr2) protein is abundantly expressed in the heart, and plasma Ucn2 levels were higher in patients with heart failure compared to healthy controls, indicating that endogenous Crhr2 is associated with heart failure. PMID: 28550160

    11. study showed that Ucn2 and Ucn3 differentially regulate the LPS-induced TNF-alpha and IL-10 expression and secretion in trophoblast explants acting through CRH-R2. Ucn2 is proinflammatory. PMID: 22000474

    14. Unlike urocortin-1 levels, higher levels of urocortin 2 are not associated with worse left ventricular diastolic performance in patients with chronic systolic heart failure. PMID: 20670842
    15. Urocortin 2 may play a role in the regulation of estradiol production throughout pregnancy, thereby contributing to the placental regulation of key reproductive events in pregnancy maintenance and parturition. PMID: 19417223
    16. Placental Ucn2 and Ucn3 expression is sensitive to O(2) tensions and mediated by HIF-1alpha. In preeclampsia, the increased expression of both peptides may reflect a response to the oxidative stress. PMID: 20616367
    17. SCP and UCN are potent activators of the p42/44 MAPK pathway, with SRP able to induce phosphorylation of p42/44 MAPK as well, albeit not as pronounced PMID: 14519439
    18. data suggest a distinctive role for corticotropin-releasing hormone receptor 2 specific agonists like urocortin II in the control of myometrial contractility during human pregnancy PMID: 14592950
    19. data indicate that intracisternal Ucn 2 induced a central CRF(2)-mediated inhibition of gastric emptying involving sympathetic alpha(1)-adrenergic mechanisms independent from the vagus contrasting with the vagal-dependent inhibitory actions of CRF & Ucn 1 PMID: 16223946
    20. the 38 amino acid urocortin 2 peptide is the minimal pharmacophore PMID: 16476507
