Pyrroloquinoline Quinine and LY294002 Changed Cell Cycle and Apoptosis by Regulating PI3K-AKT-GSK3β Pathway in SH-SY5Y Cells

To verify the role of PI3K-AKT-GSK3β pathway during manganese (Mn)-induced cell death, apoptosis, related indicators were investigated. SH-SY5Y cells were directly exposed to different concentrations of MnCl2. Then, cell viability, apoptosis, necrosis rate, and cell cycle were detected by MTT, FITC Annexin V Apoptosis Detection Kit with PI and PI staining. Then, in two intervention groups, cells were preconditioned with agonist (PQQ) and...
