Aripiprazole, but Not Olanzapine, Alters the Response to Oxidative Stress in Fao Cells by Reducing the Activation of Mitogen-Activated Protein Kinases (MAPKs) and Promoting Cell Survival.

ABSTRACT: Prolonged use of atypical antipsychotics (AAPs) is commonly associated with increased cardiovascular disease risk. While weight gain and related health issues are generally considered the primary contributors to this risk, direct interference with mitochondrial bioenergetics, particularly in the liver where these drugs are metabolized, is emerging as an additional contributing factor. Here, we compared the effects of two AAPs with disparate metabolic profiles on the response of Fao hepatoma cells to oxidative stress: olanzapine (OLA), which is obesogenic, and aripiprazole (ARI), which is not. Results showed that cells treated with ARI exhibited resistance to H₂O₂-induced oxidative stress, while OLA treatment had the opposite effect. Despite enhanced survival, ARI-trea
