EGCG Protects against 6-OHDA-Induced Neurotoxicity in a Cell Culture Model

Figure 4

⁵⁵Fe iron uptake by the N27 cell. Cells were treated with EGCG (100 μM) for 2 h followed by 6-OHDA (25 μM) for 24 h. Percentage of ⁵⁵Fe uptake was calculated by measuring the fraction of radioactivity in the cell lysates in relation to initial added radioactivity. Values (mean ± SEM, ) are expressed as percentage of controls after normalizing with protein concentration. Bar means without a common letter differ. ; .
