The table shows the FBA results of the basic dopaminergic nerve cell experiment. Four different target functions were selected for the simulation: (i) minApo, (ii) maxApo, (iii) minDeg, (iv) maxDeg. The table includes three reactions groups: ‘ROS production (dopamine)’, ‘ αSYN aggregation’ and ‘Toxic effects of αSYN aggregates’. ‘ROS production (dopamine)’ comprise all reactions of the dopamine synthesis and metabolism, where ROS or ROS-like metabolites are produced. These reactions are DOPALlikeROS, SalsolinollikeROS, DopaminesyntheseROSout, DOPALSynthesis2, and HVAldehydSynthesis2. ‘ αSYN aggregation’ includes the reaction of DA and αSYN (SNCADopamineAggregation), the reaction of ROS and αSYN (SNCAROSAggregation), and the increased αSYN expression (SNCAOverexpression). Finally, ‘Toxic effects of αSYN aggregates’ contains the reaction MitochondriaDamageSNCAAggregates and isdamagedProtein. For each reaction group, the reaction fluxes are added up to obtain a better overview of the corresponding topic.
