*2.1. Cell Culture*

Human SH-SY5Y neuroblastoma cells were cultured at 37 ◦C and 5% CO2 in Dulbecco's modified Eagle medium (DMEM) (Invitrogen™, Life Technologies, Grand Island, NY, USA) mixed with F12 (Invitrogen™, Life Technologies, Grand Island, NY, USA), 10% fetal bovine serum (FBS) (Biowest LLC, Miami, FL, USA), and glutamine (Biological Industries, Kibbutz Beit Haemek, Israel). The medium was changed twice per week. Cells were grown to 80% confluence before treatment.
