Apart from the putative anti-cancer effect of flavonoids through their UV-blocking activity, flavonoids may be beneficial in accelerating wound healing processes via the regulation of numerous pathways, notably Wnt/β-catenin, Hippo, TGF-β, Hedgehog, c-Jun, Nrf2/ARE, NF-κB, MAPK/ERK, Ras/Raf/MEK/ERK, PI3K/Akt, and NO [229]. This evidence concerns the gene JUN and cancer.
