Besides, it was also preliminarily speculated that PD could be used for the treatment of VIN-induced neuropathic pain via the IL-17 signaling pathway, AGE-RAGE signaling pathway in diabetic complications, cellular senescence, FoxO signaling pathway, NOD-like receptor signaling pathway, Th17 cell differentiation, and HIF-1 signaling pathway due to the high representation of RELA, IL-6, TP53, MAPK3, and MAPK1 targets. This evidence concerns the gene RELA and vulvar intraepithelial neoplasia.
