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/cm2/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.
