Transcriptomics reveals the potential mechanism of ellagic acid extract from raspberry on wound healing

The aim of this study was to reveal the mechanism of its wound healing function at the molecular level using transcriptome sequencing technology. The results showed that EAE mainly upregulated Cyclin A gene through AMPK signalling pathway, activated cell cycle pathway, promoted DNA synthesis, accelerated mitosis, and thus promoted the proliferation of Human immortalized keratinocytes (HaCaT) cells. In addition, analysis of downregulated gene enrichment revealed that these genes were significantly or very significantly enriched not only in the cytokine-cytokine receptor interaction pathway but also in the TNF and the NF-kappa B signalling inflammatory classical pathway. It was mainly through downregulation of genes such as Fn14, CCL2, CCL5, CARD14 and LTB that prevented inflammatory responses while delaying apoptosis. The results of this study provided important information for the molecular mechanism of wound healing of EAE and provided a basis for further development of functional products of raspberry.
