A review of human studies identified the mir-663a as upregulated two days post-burn in deep partial thickness burn skin compared to normal skin [Siu et al. DOI:10.1111/wrr.13100]. A study in mice demonstrated that the mir-663a controls the TGF-β1 signaling pathway, where its downregulation upregulates TGF-β1 expression to activate the TGF-β1/Smad pathway, facilitating re-epithelialization and granulation tissue production during wound healing [Wang et al. DOI:10.1007/s00438-024-02183-w].
