Effect of CC and FCC on antioxidant enzymes and neuronal stress marker in SH-SY5Y neuroblastoma cells. The antioxidant enzymes (a) superoxide dismutase (SOD), (b) catalase (CAT), and neuronal marker (c) brain-derived neurotrophic factor (BDNF) genes expression levels were detected by quantitative real-time PCR. “+, -”: Cells were treated with or without H₂O₂. The data are expressed as mean ± SD, n = 3. ^### p < 0.001 compared to the control cells and * p < 0.05, ** p < 0.05, *** p < 0.001 compared to H₂O₂ treatment alone, and ^$ p < 0.05 compared to CC 100 µg/mL treatment group.
