| In Vitro | Diprotin A (100 μM; 30 minutes after CXCR4-blocker or Src-inhibitor treatment) induces the phosphorylation of Src [Tyr 416] and VE-cadherin [Tyr731] in hECs in both normoxia and H/R conditions in human endothelial cells and disrupts endothelial cell-to-cell junctions, which are attenuated by CXCR4 (receptor of SDF-1α)-blocker or Src-inhibitor[1]. Western Blot Analysis[1] Cell Line: Human endothelial cells[1] Concentration: 100 μM Incubation Time: 30 minutes after CXCR4-blocker or Src-inhibitor treatment Result: Induced the phosphorylation of Src [Tyr 416] and VE-cadherin [Tyr731] in hECs. |
| In Vivo | Diprotin A (intraperitoneal injection; 70 μg/kg; twice daily; 7 days) increases the phosphorylation of Src and VE-cadherin and aggravates vascular leakage in the retinas. Collectively, Diprotin A induces vascular leakage by augmenting the SDF-1α/CXCR4/Src/VE-cadherin signaling pathway[1]. Animal Model: Streptozotocin-induced diabetic retinopathy model in wild-type C57/BL6 mice[1] Dosage: 70 μg/kg Administration: Intraperitoneal injection; twice daily; 7 days Result: Induced vascular leakage by augmenting the SDF-1α/CXCR4/Src/VE-cadherin signaling pathway. |
