Sevoflurane increased expression of DJ-1 in human M17 neuroblastoma cells. a, b Human M17 neuroblastoma cells were treated with sevoflurane at concentrations of 1, 2, 3% for 36 h. Real-time PCR analysis and Western blot analysis of DJ-1. c, d Human M17 neuroblastoma cells were treated with 2% sevoflurane for 24, 36, and 48 h. Real-time PCR analysis and Western blot analysis of DJ-1 (*P < 0.01 vs. non-treated control; n = 3–5)
