Sheng-ji Hua-yu ointment ameliorates cutaneous wound healing in diabetes via up-regulating CCN1.

Ethnopharmacological Relevance: Diabetic ulcers (DUs) are one of the most severe complications of diabetes, and efficacious therapeutic means are currently lacking. Sheng-ji Hua-yu (SJHY) ointment is a classical Chinese traditional prescription that can significantly attenuate DU defects, but the specific mechanism remains to be fully elucidated.
Aim of the Study: In order to verify the underlying mechanism of SJHY ointment in accelerating the closure of DUs.
Materials and Methods: Modular pharmacology and molecular docking were utilized to predict the therapeutic targets of SJHY ointment against DUs. Male db/db diabetic mice and HaCaT cell models induced by methylglyoxal were used to validate the findings.
Results: CCN1 was proven to be the core target of SJHY ointment involved in DUs treatment. CCN1 up-regulated by SJHY treatment (0.5 g/cm ² /day) at the mRNA and protein levels was detected on Day9 after wounding. With CCN1 knockdown, accelerated cell proliferation, migration, and anti-inflammatory effect of SJHY treatment (10 mg/L) were reversed.
Conclusions: SJHY ointment ameliorates cutaneous wound healing by up-regulating CCN1.
