TUNEL assay for the effect of CFR on the apoptosis of the SK-N-SH cells (magnification, ×200). Control group: transfected with empty control plasmids, H₂O₂ group: transfected with α-syn plasmids and 300 μM H₂O₂, H₂O₂ + CFR-L group: transfected with α-syn plasmids, 300 μM H₂O₂, and 5% CFR, and H₂O₂ + CFR-H group: transfected with α-syn plasmids, 300 μM H₂O₂, and 10% CFR.
