Traditional Chinese medicine (TCM) provides alternative treatment choices for diabetic wounds. The aim of this study was to evaluate the effects of Angelica dahurica and Rheum officinale (ARE) on diabetic wounds and its underlying action mechanism. A total of 36 healthy male Sprague–Dawley rats were randomly divided into three groups: diabetes mellitus (DM) rats treated with ARE (DM-ARE), DM rats treated with 0.9% saline (DM-NS), and non-DM rats treated with 0.9% saline (NDM-NS). DM was induced by intraperitoneal administration of 40 mg/kg of streptozotocin after a 2-week high-fat diet feeding. After excisional skin wounds and treatments, the remaining wound area (RWA) in each group was measured. The RWA in the DM-NS group (69.60% ± 2.35%) was greater than that in the DM-ARE (55.70% ± 1.85%) and NDM-NS groups (52.50% ± 2.77%) on day 6. Besides, the DM-ARE group showed higher vascular endothelial growth factor (VEGF), higher inducible nitric oxide synthase (iNOs), higher [Formula: see text]-smooth muscle actin ([Formula: see text]-SMA), and lower nuclear factor kappa-light-chain-enhancer of activated B cell (NF-[Formula: see text]B) expression in the wound skin tissue. These results showed that treatment with ARE shifted the recovery pattern of diabetic rats to the pattern of nondiabetic rats, indicating that ARE may improve wound healing in diabetic conditions.

Abstract Vascular endothelial growth factor (VEGF) and endometrial angiogenesis play a critical role in successful embryonic implantation. Despite many studies of the effects of estrogen and progesterone on VEGF expression, its focal regulation at the site of implantation is unknown. Retinoic acid (RA) has been reported to regulate VEGF in a variety of cell types. Because localized RA synthesis occurs within the periimplantation endometrium, we tested the possibility that RA regulates VEGF production in endometrial stromal cells. Using primary and telomerase-immortalized human endometrial stromal cells, we determined that RA alone did not alter constitutive levels of VEGF production, but markedly amplified secretion when the cells were cotreated with activators of VEGF gene transcription (12-O-tetradecanoyl phorbol-13-acetate, TPA; TGF-β; and IL-1β). Whereas TPA or TGF-β alone stimulated VEGF promoter activity and up-regulated mRNA levels, significant protein secretion was detected only after RA was added to the culture systems. Analysis of retinoids in secretory phase endometrial biopsies indicated that endogenous RA accumulated at concentrations sufficient to induce VEGF secretion. Polyribosome profile analysis showed that the addition of RA to transcriptional activators of VEGF shifted the translational suppressed VEGF mRNA transcripts into larger polyribosome complexes engaged in active translation. Although the precise mechanism(s) of the RA effect remains to be defined, it appears to be mediated by reactive oxygen species; the antioxidant N-acetylcysteine inhibited RA+TPA-stimulated secretion of VEGF by more than 80%. Together, our results demonstrate that in human endometrial stromal cells, RA can combine with transcriptional activators of VEGF to augment VEGF secretion through a translational mechanism of action mediated by reactive oxygen species. These findings suggest a link between the spatiotemporal changes of retinoid synthesis in the periimplantation stroma and the capacity to quickly up-regulate focal VEGF secretion needed to induce early angiogenic events of pregnancy.
