Abstract
Burn injury leads to mitochondrial dysfunction and autophagy, also known as mitophagy. The alleviation of mitochondrial damage may be a potential method for the treatment of burn injury and complications. In this animal study, we analyzed the expression of mitochondrial damage- and mitophagy-related factors, specifically PINK1 and PRKN. The results showed mitochondria damage in the skin; compared with the normal control group, genes involved in the mitochondrial damage, such as Nrf-1, UQCRC2, CYC1, and NDUFA9, as well as in the mitophagy, including PINK1, PRKN, MFN1, and USP30, were differentially expressed. Furthermore, PINK1 interacted with PRKN and participated in mitophagy in the skin. In conclusion, our data reveal more about the mechanism underlying mitophagy in burns, providing a potential clinical treatment.
