产品描述 | Desmopressin (dDAVP) is a synthetic peptide analog of natural pituitary hormone 8-arginine vasopressin (ADH) with hemostatic and anti-diuretic properties [1]. Desmopressin reduced the formation of lung nodules in F3II tumor cell injected BALB/c mice. In vitro, desmopressin blocked the F3II cell colony formation. Desmopressin could inhibit metastasis formation on V2 vasopressin receptors in both endothelial and cancer cells [1]. Desmopressin has been proved to increase the release of platelet adhesion promoting factors which is most likely von Willebrand factor (VWF), from endothelial cells (ECs). However, desmopressin had no direct effect on platelets [2]. The administration of desmopressin agglomerates in rats significantly reduced the urine production [3]. Apart from these, rats treated by desmopressin had demonstrated a stronger Pimonidazole staining in the outer and inner medulla compared to control. Desmopressin-treated rats revealed nuclear accumulation in the papilla, which was confirmed by HIF-1α immunostaining. Desmopressin-treated animals had shown a significant increase of HIF-target genes in the group of Desmopressin-regulated gene products including insulin-like growth factor binding proteins 1 and 3, fibronectin, hexokinase 2, angiopoietin 2, cathepsin D and cyclooxygenase 2. Desmopressin had been shown to cause the renal urine concentrating mechanism, leading to an upregulation of hypoxia-inducible gene expression and renal medullary hypoxia [4].
