Abstract
Background Solasonine (SS), the main active ingredient of Solanumnigrum L, has been reported to boast extensive anti-tumor, anti-oxidant, and anti-inflammatory properties. This study is committed to exploring whether solasonine can alleviate neurotoxicity resulting from sevoflurane. Materials and methods The mouse hippocampal neuron cell line HT22 was treated with sevoflurane and/or solasonine of different doses. The proliferation, inflammation, oxidative stress response, and apoptosis of HT22 cells were examined. The AMP-activated protein kinase (AMPK)/FoxO3a signaling pathway was ascertained through Western blot and cellular immunofluorescence. In in-vivo experiments, Morris water maze figured out the changes in learning and memory abilities of mice treated with 8 mg/kg solasonine and exposed to SEV. Results Sevoflurane induced apoptosis and hampered proliferation in HT22 cells. It also aggravated the release of inflammatory factors and oxidative stress mediators. Solasonine weakened neuron damage mediated by sevoflurane in a concentration-dependent pattern. Mechanically, sevoflurane clogged AMPK/FoxO3a signaling pathway activation, which was strengthened by solasonine. AMPK inhibition greatly influenced solasonine’s protective effect on HT22 cells. Invivo, solasonine prominently ameliorated learning and memory disorders and nerve damage in mice exposed to sevoflurane. Conclusions Solasonine alleviates sevoflurane-induced neurotoxicity through activating the AMPK/FoxO3a signaling pathway.
