BACKGROUND
Diabetic foot ulcers (DFU), as severe complications of diabetes mellitus (DM), significantly compromise patient health and carry risks of amputation and mortality.
AIM
To offer new insights into the occurrence and development of DFU, focusing on the therapeutic mechanisms of X-Paste (XP) of wound healing in diabetic mice.
METHODS
Employing traditional Chinese medicine ointment preparation methods, XP combines various medicinal ingredients. High-performance liquid chromatography (HPLC) identified XP’s main components. Using streptozotocin (STZ)-induced diabetic, we aimed to investigate whether XP participated in the process of diabetic wound healing. RNA-sequencing analyzed gene expression differences between XP-treated and control groups. Molecular docking clarified XP’s treatment mechanisms for diabetic wound healing. Human umbilical vein endothelial cells (HUVECs) were used to investigate the effects of Andrographolide (Andro) on cell viability, reactive oxygen species generation, apoptosis, proliferation, and metastasis in vitro following exposure to high glucose (HG), while NF-E2-related factor-2 (Nrf2) knockdown elucidated Andro’s molecular mechanisms.
RESULTS
XP notably enhanced wound healing in mice, expediting the healing process. RNA-sequencing revealed Nrf2 upregulation in DM tissues following XP treatment. HPLC identified 21 primary XP components, with Andro exhibiting strong Nrf2 binding. Andro mitigated HG-induced HUVECs proliferation, metastasis, angiogenic injury, and inflammation inhibition. Andro alleviates HG-induced HUVECs damage through Nrf2/HO-1 pathway activation, with Nrf2 knockdown reducing Andro’s proliferative and endothelial protective effects.
CONCLUSION
XP significantly promotes wound healing in STZ-induced diabetic models. As XP’s key component, Andro activates the Nrf2/HO-1 signaling pathway, enhancing cell proliferation, tubule formation, and inflammation reduction.
Core Tip: Diabetic foot ulcer (DFU) is a severe complication caused by diabetes mellitus. The healing process and time of skin wounds in diabetic mice are visibly improved by the application of X-Paste (XP). The analysis conducted on XP unveiled its 21 main components, with Andrographolide (Andro) displaying a notable binding ability with NF-E2-related factor-2 (Nrf2) by high-performance liquid chromatography. Moreover, the addition of Andro at the cellular level effectively alleviated high glucose (HG)-induced proliferation, migration, vascular injury, and inhibition of inflammatory products in human umbilical vein endothelial cells (HUVECs). Mechanistically, the Nrf2/HO-1 signaling pathway is activated by Andro, leading to the relief of HG-induced damage to HUVECs.
