Apigenin promotes survival of random skin flaps by enhancing angiogenesis, attenuating apoptosis, alleviating oxidative stress, and activating autophagy. The inhibition of autophagy by 3-methyladenine reversed the beneficial effects of apigenin on flap survival, angiogenesis, apoptosis, and oxidative stress.
Random skin flap is widely used in plastic surgery. However, flap necrosis caused by ischemia-reperfusion injury limits its clinical applications. Apigenin, a naturally occurring flavonoid mainly derived from plants, facilitates flap survival. In this study, we explored the effects of apigenin on flap survival and the underlying mechanisms. A total of 54 mice having a dorsal random flap model were randomly divided into control, apigenin, and apigenin +3-methyladenine groups. These groups were treated with dimethyl sulfoxide solution, apigenin, and apigenin +3-methyladenine, respectively. The animals were then euthanized to assess angiogenesis, apoptosis, oxidative stress, and autophagy levels through histological and protein analyses. Apigenin promotes survival of the skin flap area and reduces tissue edema. In addition, apigenin enhanced angiogenesis, attenuated apoptosis, alleviated oxidative stress, and activated autophagy. Interestingly, 3-methyladenine reversed the effects of apigenin on flap survival, angiogenesis, apoptosis, and oxidative stress through inhibition of autophagy. The findings of this study show that apigenin promotes angiogenesis, inhibits cell apoptosis, and lowers oxidative stress by mediating autophagy, thus the improving survival rate of random skin flaps.
