BAD and Parkinson disease: The PD model induced by H2O2 increased the levels of the apoptosis-promoting protein BAD/Bax and decreased the levels of anti-apoptosis proteins, such as Bcl-2, p53, CytC, and Glycogen synthase kinase 3 beta (GSK3β), but there was a marked decrease in apoptosis-promoting protein levels and an increase in anti-apoptosis protein levels in the UF-treated groups.
