Transcriptional profiling of human skin fibroblast cell line Hs27 induced by herbal formula Astragali Radix and Rehmanniae Radix
چکیده انگلیسی

Ethnopharmacological relevanceThe herbs Astragali Radix (AR) and Rehmanniae Radix (RR) have long been used in traditional Chinese Medicine and serve as the principal herbs in treating diabetic foot ulcer.Aim of the studyChinese herbal formulus comprising Astragali Radix (AR) and Rehmanniae Radix (RR) have been shown to improve the healing of diabetic foot ulcer through enhancing the viability of primary fibroblasts in diabetic patients suffering insulin resistance. Our previous study demonstrated that the herbal formula NF3 comprising of AR and RR in the ratio of 2:1 was effective in promoting wound healing in diabetic rats, and in vitro data indicated that the wound healing effects of NF3 might be due to the regulation and coordination of inflammation, angiogenesis and tissue regeneration. However, the underlying molecular mechanism has not been well investigated. In this study, we investigated the cellular and molecular effects of the herbal formula NF3 on human skin fibroblast cells.Materials and methodsHuman skin fibroblast cells Hs27 were treated with NF3 ranging from 0 to 8 mg/ml for 24 h, and the cells without NF3 treatment were used as control. Cell proliferation assay and cell cycle analysis were performed. Transcriptional profiles of Hs27 cells upon NF3 treatment were acquired by using a human cDNA microarray containing 10,000 genes, and the signaling pathways differentially regulated by NF3 were identified and analyzed.ResultsNF3 promoted Hs27 cell proliferation and cell cycle progression. Microarray analysis revealed that 116 genes were differentially expressed upon NF3 treatment. Functional analysis of the genes indicated that NF3 mainly activated Wnt and angiogenesis related pathways, which are directly related to cell proliferation, angiogenesis, extracellular matrix (ECM) formation and inflammation during the process of wound healing.ConclusionThis study provides insight into the molecular mechanism of how the herbal formula Astragali Radix and Rehmanniae Radix may serve as potential therapeutics for wound healing.
