Abstract:
Endothelial cells are crucially involved in wound healing angiogenesis, restoring blood flow to wound tissues. Our previous study demonstrated that the Chinese 2‐herb formula (NF3) possesses significant wound healing effect in diabetic foot ulcer rats with promising in vitro proangiogenic effects on human umbilical vein endothelial cells (HUVEC). Here, we present the comparative global proteome analysis of NF3‐treated HUVEC in static or scratch conditions, screening the comprehensive molecular targets in governing the proangiogenic response in wound healing. Our results suggest plasminogen activator inhibitor‐1, specifically down‐regulated in static condition and Annexin A1 and Annexin A2, up‐regulated in scratch condition, as principal proteins responsible for the proangiogenesis in wound healing. We also identified a panel of cytoskeleton regulatory proteins in static and scratch condition, mediating the migratory behavior of NF3‐treated HUVEC. The key proteins in static state include myosin regulatory light polypeptide 9, SPAST, tropomyosin (TPM)2, and Vimentin while that in scratch state contained prelamin‐A/C, TPM1, TPM2, and Vimentin. In addition, NF3 was shown to regulate transcription and translation, cell–cell interaction, and ROS defense in HUVEC. Proliferation and migration assays further confirmed the identified principal proteins plasminogen activator inhibitor‐1 and Annexin A2 which are responsible for NF3‐induced proangiogenesis of HUVEC in wound healing. This is the first study on the global proteome expression of NF3‐treated HUVEC with the identification of the differences at the molecular level, between static and scratch conditions involved in wound healing angiogenesis.
