Interaction Information:
Comment | 6-OHDA induces 40% cell death after 24 h of treatment. |
Formal Description Interaction-ID: 4126 |
|
Comment | Production of free radicals in the cells is significantly increased after 2h treatment with 6-OHDA. Besides the increase in intracellular oxidants, 6-OHDA also causes mitochondrial function impairment and DNA damage. Altogether, these events induce loss of mitochondrial potential, cytochrome c release and initiation of the apoptotic process. |
