Effects of Coff/Caff plus Mel on the expression level of Nrf2 in N2a/APP cells treated with regimen 1.
Notes: N2a/APP cells were treated with Coff or Caff at 10 μM for 12 hours in the day, followed by Mel at 1, 5, or 10 μM for another 12 hours in the night. Cells were harvested, lysed, and subjected to SDS-PAGE. The target protein was probed using corresponding primary antibody. β-actin was used as the internal control for value normalization. (A) Representative blots of Nrf2; and bar graphs showing the relative expression level of Nrf2 in response to Coff and Mel (B), and Caff and Mel (C). ***P<0.001, by one-way ANOVA.
Abbreviations: ANOVA, analysis of variance; APP, amyloid precursor protein; Caff, caffeine; Coff, coffee; Mel, melatonin; N2a, Neuro-2a; SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis.
